Subject: [PATCH 0001/2145] DATAJDBC-166 - Allow registration of RowMappers
 based on result type.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

RowMapper can be configured either via the @Query(rowMapperClass = …​.) or by registerign a RowMapperMap bean and register RowMapper per method return type.

                @Bean
                RowMapperMap rowMappers() {
                        return new ConfigurableRowMapperMap() //
                                        .register(Person.class, new PersonRowMapper()) //
                                        .register(Address.class, new AddressRowMapper());
                }

When determining the RowMapper to use for a method the following steps are followed based on the return type of the method:

1. If the type is a simple type no RowMapper is used. Instead the query is expected to return a single row with a single column and a conversion to the return type is applied to that value.

2. The entity classes in the RowMapperMap are iterated until one is found that is a superclass or interface of the return type in question. The RowMapper registered for that class is used. Iterating happens in the order of registration, so make sure to register more general types after specific ones.

If applicable wrapper type like collections or Optional are unwrapped. So a return type of Optional<Person> will use the type Person in the steps above.

 If you compile your sources with the `-parameters` compiler flag you can omit the `@Param` annotations.
 
+==== Custom RowMapper
+
+You can configure the `RowMapper` to use using either the `@Query(rowMapperClass = ....)` or you can register a `RowMapperMap` bean and register `RowMapper` per method return type.

 === Id generation
 
 Spring Data JDBC uses the id to identify entities but also to determine if an entity is new or already existing in the database.

Subject: [PATCH 0004/2145] DATAJDBC-183 - Using dedicated class for handling
 map entries.

Instead of using Map.Entry we now use a dedicated class to hold key and value of a map entry.
This avoids side effects from the implementation of Map.Entry.

Replaced call to saveReferencedEntities with insertReferencedEntities which is simpler but equivalent since referenced entities always get only inserted, never updated.

Removed superfluous methods resulting from that change.

Subject: [PATCH 0006/2145] DATAJDBC-186 - Removed requirement for id
 properties.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It is now ok for an entity to be “new” after saving.
We now only check that an entity is not new when the id is provided by the database.
If in such a case the entity is still “new” after saving it basically means obtaining the id from JDBC and setting it in the entity failed.

Removed need for entities in maps to have an id.

Together these changes simplify the requirements for Map values, which now can be value objects.

Subject: [PATCH 0010/2145] DATAJDBC-189 - Move default implementation to
 NamingStrategy

This makes it nicer to overwrite certain aspects with a lambda instead of an anonymous class. Brings the naming strategy in line with pairs like WebMvcConfigurer / WebMvcConfigurerAdapter.

Subject: [PATCH 0011/2145] DATAJDBC-189 - Polishing.

Removed DefaultNamingStrategy since we don't have GA release breaking APIs is still ok.
Introduced an instance of NamingStrategy so we don't have to create a new class whereever we just want the default implementation.

JavaDoc.
Formatting

Subject: [PATCH 0014/2145] DATAJDBC-155 - Simplified construction of
 JdbcRepositoryFactory.

Made the DefaultDataAccessStrategy actually the default for JdbcRepositoryFactoryBean.
Therefore the injection of a strategy is optional.

Simplified constructors of DefaultDataAccessStrategy.
Created factory method to construct a correct DataAccessStrategy for use with MyBatis.

Did some untangling in the test application context configurations.

Subject: [PATCH 0017/2145] DATAJDBC-178 - Polishing.

Renamed MyBatisNamingStrategy into NamespaceStrategy.
This avoids the confusion with the existing NamingStrategy.

Introduced a default instance.
Added a method creating a proper DataAccessStrategy with a NamespaceStrategy.

JavaDoc.

 There are few ways to tweak this behavior.

 One important constraint is that after saving an entity the entity shouldn't be _new_ anymore.

Subject: [PATCH 0021/2145] DATAJDBC-197 - Repositories find methods now emit
 AfterLoadEvents as intended.

Event publishing moved into the JdbcEntityTemplate in order to ensure events for AggregateRoots.

Removed superfluous AggregateChange from AfterCreation event.

Subject: [PATCH 0032/2145] DATAJDBC-204 - Polishing.

Extracted ApplicationContext and Repository construction into method in order to make the actual test stand out more.
Split a test in two.
JavaDoc.
Code formatting.
Removed access modifiers in tests.

Subject: [PATCH 0039/2145] DATAJDBC-209 - Improve assertion on The
 QueryAnnotationHsqlIntegrationTests#executeCustomQueryWithReturnTypeIsDate

Since Timestamp extends Date the repository returns the Timestamp as it comes from the database.
Trying to compare that to an actual Date results in non determistic results, so we have to use an actual Timestamp.

Original pull request: #66.

Date: Fri, 18 May 2018 13:57:46 +0200
Subject: [PATCH 0054/2145] DATAJDBC-106 - Polishing.

Moved annotation processing of @Table and @Column into metamodel classes so that the NamingStrategy is only responsible for generic fallbacks. Allow @Column to be used as meta-annotation.

From d0a8af21a3ce1c8143efd7d99166d6e881602c6f Mon Sep 17 00:00:00 2001
From: Oliver Gierke <ogierke@pivotal.io>
Date: Fri, 18 May 2018 15:11:27 +0200
Subject: [PATCH 0055/2145] DATAJDBC-137 - Polishing.

Moved the dependency to NamedParameterJdbcOperations out of JdbcMappingContext. This revealed that despite the DataAccessStrategy abstraction, there are a couple of places in the query execution subsystem that work with a plain NamedParameterJdbcOperations instance, so that we now have to carry that around all the way from the repository factory bean. Improving that is subject for further changes.

A bit of JavaDoc and generics polish here and there.

Subject: [PATCH 0058/2145] DATAJDBC-220 - Added a Degraph test for inter
 module dependencies.

The existing test only analysed Spring Data JDBC itself.
The new test also considers packages from commons and treats

    org.springframework.data.x.X

and

    org.springframework.data.jdbc.x.Y

as belonging to the same "sub-module" "x".

Subject: [PATCH 0059/2145] DATAJDBC-143 - Removed domain type parameter form
 JdbcEntityOperations.save().

Such a parameter would only make sense with inheritance and we don't support inheritance at all in the moment.
Anything we need in order to support inheritance should be added once we do support inheritance.

+[[jdbc.repositories]]
+= JDBC Repositories
+
+This chapter will point out the specialties for repository support for JDBC. This builds on the core repository support explained in <<repositories>>.
+So make sure you've got a sound understanding of the basic concepts explained there.
+
+[[jdbc.introduction]]
+== Introduction
+
+[[jdbc.why]]
+=== Why Spring Data JDBC?
+
+The main persistence API for relational databases in the Java world is certainly JPA, which has it's own Spring Data module.
+Why is there another one?
+
+JPA does a lot of things in order to help the developer.
+Among others it tracks changes to entities.
+It does lazy loading for you.
+It allows to map a wide array of object constructs to an equally wide array of database design.
+
+This is great and makes a lot of things really easy.
+Just take a look at a basic JPA tutorial.
+But often it gets really confusing why JPA does a certain thing.
+Or things that are really simple conceptually get rather difficult with JPA.
+
+Spring Data JDBC aims to be much simpler conceptually:
+
+* If you load an entity, SQL statements get executed and once this is done you have a completely loaded entity.
+No lazy loading or caching is done.
+
+* If you save and entity it gets saved.
+If you don't it doesn't.
+There is no dirty tracking and no session.
+
+* There is a simplistic model of how to map entities to tables.
+It probably only works for rather simple cases.
+If you don't like that, just code your strategy yourself.
+Spring Data JDBC will offer only very limited support for customizing the strategy via annotations.
+
+[[jdbc.domain-driven-design]]
+=== Domain Driven Design and Relational Databases.
+
+All Spring Data modules are inspired by the concepts of Repository, Aggregate and Aggregate Root from Domain Driven Design.
+These are possibly even more important for Spring Data JDBC because they are to some extend contrary to normal practice when working with relational databases.
+
+An *Aggregate* is a group of entities that is guaranteed to be consistent between atomic changes to it.
+A classic example is an `Order` with `OrderItems`.
+A property on `Order`, e.g. `numberOfItems` will be consistent with the actual number of `OrderItems`.
+
+References across Aggregates aren't guaranteed to be consistent at all times.
+They are just guaranteed to become eventual consistent.
+
+Each Aggregate has exactly one *Aggregate Root* which is one of the enties of the Aggregate.
+The Aggregate gets only manipulated through methods on that Aggregate Root.
+These are the *atomic changes* mentioned above.
+
+*Repositories* are an abstraction over a persistent store that look like a collection of all the Aggregates of a certain type.
+For Spring Data in general this means you want to have one `Repository` per Aggregate Root.
+For Spring Data JDBC this means above that: All entities reachable from an Aggregate Root are considered to be part of that Aggregate Root.
+It is expected that no table outside that Aggregate has a foreign key to that table.
+
+WARNING: Especially in the current implementation entities referenced from an Aggregate Root will get deleted and recreated by Spring Data JDBC!
+
+Of course you can always overwrite the Repository methods with implementations that match your style of working and designing your database.
+
+[[jdbc.java-config]]
+=== Annotation based configuration
+The Spring Data JDBC repositories support can be activated by an annotation through JavaConfig.
+
+.Spring Data JDBC repositories using JavaConfig
+====
+[source, java]
+----
+@Configuration
+@EnableJdbcRepositories
+class ApplicationConfig {
+
+  @Bean
+  public DataSource dataSource() {
+
+    EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
+    return builder.setType(EmbeddedDatabaseType.HSQL).build();
+  }
+
+}
+----
+====
+
+The just shown configuration class sets up an embedded HSQL database using the `EmbeddedDatabaseBuilder` API of spring-jdbc. We finally activate Spring Data JDBC repositories using the `@EnableJdbcRepositories`. If no base package is configured it will use the one the configuration class resides in.
+
+[[jdbc.entity-persistence]]
+== Persisting entities
+
+Saving an Aggregate can be performed via the `CrudRepository.save(…)`-Method. If the Aggregate is a new Aggregate this will result in an insert for the Aggregate Root, followed by insert statments for all directly or indirectly referenced entities.
+
+If the Aggregate Root is _not new_ all referenced entities will get deleted, the Aggregate Root updated and all referenced entities will get inserted again.
+
+NOTE: This approach has some obvious downsides.
+If only few of the referenced entities have been actually changed the deletion and insertion is wasteful.
+While this process could and probably will be improved there are certain limitations to what Spring Data can offer.
+It does not know the previous state of an Aggregate.
+So any update process always has to take whatever it finds in the database and make sure it converts it to whatever is the state of the entity passed to the save method.
+
+[[jdbc.entity-persistence.types]]
+=== Supported types in your entity
+
+Properties of the following types are currently supported:
+
+* all primitive types and their boxed types (`int`, `float`, `Integer`, `Float` ...)
+
+* enums get mapped to their name.
+
+* `String`
+
+* `java.util.Date`, `java.time.LocalDate`, `java.time.LocalDateTime`, `java.time.LocalTime`
+
+and anything your database driver accepts.
+
+* references to other entities. They will be considered a one-to-one relationship.
+It is optional for such entities to have an id attribute.
+The table of the referenced entity is expected to have an additional column named like the table of the referencing entity.
+This name can be changed by implementing `NamingStrategy.getReverseColumnName(JdbcPersistentProperty property)` according to your preferences.
+
+* `Set<some entity>` will be considered a one-to-many relationship.
+The table of the referenced entity is expected to have an additional column named like the table of the referencing entity.
+This name can be changed by implementing `NamingStrategy.getReverseColumnName(JdbcPersistentProperty property)` according to your preferences.
+
+* `Map<simple type, some entity>` will be considered a qualified one-to-many relationship.
+The table of the referenced entity is expected to have two additional columns: One named like the table of the referencing entity for the foreign key and one with the same name and an additional `_key` suffix for the map key.
+This name can be changed by implementing `NamingStrategy.getReverseColumnName(JdbcPersistentProperty property)` and `NamingStrategy.getKeyColumn(JdbcPersistentProperty property)` according to your preferences.
+
+* `List<some entity>` will be mapped like a  `Map<Integer, some entity>`.
+
+The handling of referenced entities is very limited.
+This is based on the idea of Aggregate Roots as described above.
+If you reference another entity that entity is by definition part of your Aggregate.
+So if you remove the reference the previously referenced entity will get deleted.
+This also means references will be 1-1 or 1-n, but not n-1 or n-m.
+
+If you are having n-1 or n-m references you are by definition dealing with two separate Aggregates.
+References between those should be encoded as simple ids, which should map just fine with Spring Data JDBC.
+
+[[jdbc.entity-persistence.naming-strategy]]
+=== NamingStrategy
+
+When you use the standard implementations of `CrudRepository` as provided by Spring Data JDBC it will expect a certain table structure.
+You can tweak that by providing a https://github.com/spring-projects/spring-data-jdbc/blob/master/src/main/java/org/springframework/data/jdbc/mapping/model/NamingStrategy.java[`NamingStrategy`] in your application context.
+
+[[jdbc.entity-persistence.state-detection-strategies]]
+=== Entity state detection strategies
+
+Spring Data JDBC offers the following strategies to detect whether an entity is new or not:
+
+.Options for detection whether an entity is new in Spring Data JDBC
+[options = "autowidth"]
+|===============
+|Id-Property inspection (*default*)|By default Spring Data JDBC inspects the identifier property of the given entity.
+If the identifier property is `null`, then the entity will be assumed as new, otherwise as not new.
+|Implementing `Persistable`|If an entity implements `Persistable`, Spring Data JDBC will delegate the new detection to the `isNew(…)` method of the entity.
+See the link:$$http://docs.spring.io/spring-data/data-commons/docs/current/api/index.html?org/springframework/data/domain/Persistable.html$$[JavaDoc] for details.
+|Implementing `EntityInformation`|You can customize the `EntityInformation` abstraction used in the `SimpleJdbcRepository` implementation by creating a subclass of `JdbcRepositoryFactory` and overriding the `getEntityInformation(…)` method accordingly.
+You then have to register the custom implementation of `JdbcRepositoryFactory` as a Spring bean.
+Note that this should be rarely necessary. See the link:$$http://docs.spring.io/spring-data/data-jdbc/docs/current/api/index.html?org/springframework/data/jdbc/repository/support/JdbcRepositoryFactory.html$$[JavaDoc] for details.
+|===============
+
+[[jdbc.entity-persistence.id-generation]]
+=== Id generation
+
+Spring Data JDBC uses the id to identify entities.
+The id of an entity must be annotated with Spring Data's https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
+
+When your data base has some autoincrement column for the id column the generated value will get set in the entity after inserting it into the database.
+
+One important constraint is that after saving an entity the entity must not be _new_ anymore.
+With autoincrement columns this happens automatically since the the id gets set by Spring Data with the value from the id column.
+If you are not using autoincrement columns you can use that using a `BeforeSave`-listener which sets the id of the entity (see below).
+
+[[jdbc.query-methods]]
+== Query methods
+
+[[jdbc.query-methods.strategies]]
+=== Query lookup strategies
+
+The JDBC module only supports defining a query manually as a String in a `@Query` annotation.
+Deriving a query from the name of the method is currently not supported.
+
+[[jdbc.query-methods.at-query]]
+=== Using @Query
+
+.Declare query at the query method using @Query
+====
+[source, java]
+----
+public interface UserRepository extends CrudRepository<User, Long> {
+
+  @Query("select firstName, lastName from User u where u.emailAddress = :email")
+  User findByEmailAddress(@Param("email") String email);
+}
+----
+====
+
+[NOTE]
+====
+Spring fully supports Java 8’s parameter name discovery based on the `-parameters` compiler flag. Using this flag in your build as an alternative to debug information, you can omit the `@Param` annotation for named parameters.
+====
+
+[NOTE]
+====
+Spring Data JDBC only support named parameters.
+====
+
+
+[[jdbc.query-methods.at-query.custom-rowmapper]]
+==== Custom RowMapper
+
+You can configure the `RowMapper` to use, using either the `@Query(rowMapperClass = ....)` or you can register a `RowMapperMap` bean and register `RowMapper` per method return type.
+
+[source,java]
+----
+@Bean
+RowMapperMap rowMappers() {
+	return new ConfigurableRowMapperMap() //
+		.register(Person.class, new PersonRowMapper()) //
+		.register(Address.class, new AddressRowMapper());
+}
+----
+
+When determining the `RowMapper` to use for a method the following steps are followed based on the return type of the method:
+
+1. If the type is a simple type, no `RowMapper` is used.
+    Instead the query is expected to return a single row with a single column and a conversion to the return type is applied to that value.
+
+2. The entity classes in the `RowMapperMap` are iterated until one is found that is a superclass or interface of the return type in question.
+    The `RowMapper` registered for that class is used.
+    Iterating happens in the order of registration, so make sure to register more general types after specific ones.
+
+If applicable, wrapper types like collections or `Optional` are unwrapped.
+Thus, a return type of `Optional<Person>` will use the type `Person` in the steps above.
+
+
+[[jdbc.query-methods.at-query.modifying]]
+==== Modifying query
+
+You can mark as a modifying query using the `@Modifying` on query method.
+
+[source,java]
+----
+@Modifying
+@Query("UPDATE DUMMYENTITY SET name = :name WHERE id = :id")
+boolean updateName(@Param("id") Long id, @Param("name") String name);
+----
+
+The return types that can be specified are `void`, `int`(updated record count) and `boolean`(whether record was updated).
+
+
+[[jdbc.mybatis]]
+== MyBatis Integration
+
+For each operation in `CrudRepository` Spring Data Jdbc will execute multiple statements.
+If there is a https://github.com/mybatis/mybatis-3/blob/master/src/main/java/org/apache/ibatis/session/SqlSessionFactory.java[`SqlSessionFactory`] in the application context, Spring Data will check for each step if the `SessionFactory` offers a statement.
+If one is found that statement will be used (including its configured mapping to an entity).
+
+The name of the statement is constructed by concatenating the fully qualified name of the entity type  with `Mapper.` and a String determining the kind of statement.
+E.g. if an instance of `org.example.User` is to be inserted Spring Data Jdbc will look for a statement named `org.example.UserMapper.insert`.
+
+Upon execution of the statement an instance of [`MyBatisContext`] will get passed as an argument which makes various arguments available to the statement.
+
+[cols="default,default,default,asciidoc"]
+|===
+| Name | Purpose | CrudRepository methods which might trigger this statement | Attributes available in the `MyBatisContext`
+
+| `insert` | Insert for a single entity. This also applies for entities referenced by the aggregate root. | `save`, `saveAll`. |
+`getInstance`:
+        the instance to be saved
+
+`getDomainType`: the type of the entity to be saved.
+
+`get(<key>)`: id of the referencing entity, where `<key>` is the name of the back reference column as provided by the `NamingStrategy`.
+
+
+| `update` | Update for a single entity. This also applies for entities referenced by the aggregate root. | `save`, `saveAll`.|
+`getInstance`: the instance to be saved
+
+`getDomainType`: the type of the entity to be saved.
+
+| `delete` | Delete  a single entity. | `delete`, `deleteById`.|
+`getId`: the id of the instance to be deleted
+
+`getDomainType`: the type of the entity to be deleted.
+
+| `deleteAll-<propertyPath>` | Delete all entities referenced by any aggregate root of the type used as prefix via the given property path.
+Note that the type used for prefixing the statement name is the name of the aggregate root not the one of the entity to be deleted. | `deleteAll`.|
+
+`getDomainType`: the type of the entities to be deleted.
+
+| `deleteAll` | Delete all aggregate roots of the type used as the prefix | `deleteAll`.|
+
+`getDomainType`: the type of the entities to be deleted.
+
+| `delete-<propertyPath>` | Delete all entities referenced by an aggregate root via the given propertyPath | `deleteById`.|
+
+`getId`: the id of the aggregate root for which referenced entities are to be deleted.
+
+`getDomainType`: the type of the entities to be deleted.
+
+
+| `findById` | Select an aggregate root by id | `findById`.|
+
+`getId`: the id of the entity to load.
+
+`getDomainType`: the type of the entity to load.
+
+| `findAll` | Select all aggregate roots | `findAll`.|
+
+`getDomainType`: the type of the entity to load.
+
+| `findAllById` | Select a set of aggregate roots by ids | `findAllById`.|
+
+`getId`: list of  ids of the entities to load.
+
+`getDomainType`: the type of the entity to load.
+
+
+| `findAllByProperty-<propertyName>` | Select a set of entities that is referenced by another entity. The type of the referencing entity is used for the prefix. The referenced entities type as the suffix. | All `find*` methods.|
+
+`getId`: the id of the entity referencing the entities to be loaded.
+
+`getDomainType`: the type of the entity to load.
+
+| `count` | Count the number of aggregate root of the type used as prefix | `count` |
+
+`getDomainType` the type of aggregate roots to count.
+|===
+
+[[jdbc.events]]
+== Events
+
+Spring Data Jdbc triggers events which will get published to any matching `ApplicationListener` in the application context.
+For example the following listener will get invoked before an aggregate gets saved.
+
+[source,java]
+----
+@Bean
+public ApplicationListener<BeforeSave> timeStampingSaveTime() {
+
+	return event -> {
+
+		Object entity = event.getEntity();
+		if (entity instanceof Category) {
+			Category category = (Category) entity;
+			category.timeStamp();
+		}
+	};
+}
+----
+
+.Available events
+|===
+| Event | When It's Published
+
+| https://docs.spring.io/spring-data/jdbc/docs/1.0.0.M1/api/org/springframework/data/jdbc/mapping/event/BeforeDeleteEvent.java[`BeforeDeleteEvent`]
+| before an aggregate root gets deleted.
+
+| https://docs.spring.io/spring-data/jdbc/docs/1.0.0.M1/api/org/springframework/data/jdbc/mapping/event/AfterDeleteEvent.java[`AfterDeleteEvent`]
+| after an aggregate root got deleted.
+
+| https://docs.spring.io/spring-data/jdbc/docs/1.0.0.M1/api/org/springframework/data/jdbc/mapping/event/AfterDelete.java[`BeforeDeleteEvent`]
+| before an aggregate root gets saved, i.e. inserted or updated but after the decision was made if it will get updated or deleted.
+The event has a reference to an https://docs.spring.io/spring-data/jdbc/docs/1.0.0.M1/api/org/springframework/data/jdbc/core/conversion/AggregateChange.java[`AggregateChange`] instance.
+The instance can be modified by adding or removing https://docs.spring.io/spring-data/jdbc/docs/1.0.0.M1/api/org/springframework/data/jdbc/core/conversion/DbAction.java[`DbAction`]s.
+
+| https://docs.spring.io/spring-data/jdbc/docs/1.0.0.M1/api/org/springframework/data/jdbc/mapping/event/AfterSaveEvent.java[`AfterSaveEvent`]
+| after an aggregate root gets saved, i.e. inserted or updated.
+
+| https://docs.spring.io/spring-data/jdbc/docs/1.0.0.M1/api/org/springframework/data/jdbc/mapping/event/AfterLoadEvent.java[`AfterLoadEvent`]
+| after an aggregate root got created from a database `ResultSet` and all it's property set
+|===
+
+[[jdbc.logging]]
+== Logging
+
+Spring Data JDBC does little to no logging of it's own.
+Instead the mechanics to issue SQL statements do provide logging.
+Thus if you want to inspect what SQL statements are executed activate logging for Springs https://docs.spring.io/spring/docs/current/spring-framework-reference/data-access.html#jdbc-JdbcTemplate[`NamedParameterJdbcTemplate`] and/or http://www.mybatis.org/mybatis-3/logging.html[MyBatis].
+
+[[jdbc.transactions]]
+== Transactionality
+CRUD methods on repository instances are transactional by default.
+For reading operations the transaction configuration `readOnly` flag is set to `true`, all others are configured with a plain `@Transactional` so that default transaction configuration applies.
+For details see JavaDoc of link:$$http://docs.spring.io/spring-data/data-jdbc/docs/current/api/index.html?org/springframework/data/jdbc/repository/support/SimpleJdbcRepository.html$$[`SimpleJdbcRepository`]. If you need to tweak transaction configuration for one of the methods declared in a repository simply redeclare the method in your repository interface as follows:
+
+.Custom transaction configuration for CRUD
+====
+[source, java]
+----
+public interface UserRepository extends CrudRepository<User, Long> {
+
+  @Override
+  @Transactional(timeout = 10)
+  public List<User> findAll();
+
+  // Further query method declarations
+}
+----
+This will cause the `findAll()` method to be executed with a timeout of 10 seconds and without the `readOnly` flag.
+====
+
+Another possibility to alter transactional behaviour is using a facade or service implementation that typically covers more than one repository. Its purpose is to define transactional boundaries for non-CRUD operations:
+
+.Using a facade to define transactions for multiple repository calls
+====
+[source, java]
+----
+@Service
+class UserManagementImpl implements UserManagement {
+
+  private final UserRepository userRepository;
+  private final RoleRepository roleRepository;
+
+  @Autowired
+  public UserManagementImpl(UserRepository userRepository,
+    RoleRepository roleRepository) {
+    this.userRepository = userRepository;
+    this.roleRepository = roleRepository;
+  }
+
+  @Transactional
+  public void addRoleToAllUsers(String roleName) {
+
+    Role role = roleRepository.findByName(roleName);
+
+    for (User user : userRepository.findAll()) {
+      user.addRole(role);
+      userRepository.save(user);
+    }
+}
+----
+This will cause call to `addRoleToAllUsers(…)` to run inside a transaction (participating in an existing one or create a new one if none already running). The transaction configuration at the repositories will be neglected then as the outer transaction configuration determines the actual one used. Note that you will have to activate `<tx:annotation-driven />` or use `@EnableTransactionManagement` explicitly to get annotation based configuration at facades working. The example above assumes you are using component scanning.
+====
+
+[[jdbc.transaction.query-methods]]
+=== Transactional query methods
+To allow your query methods to be transactional simply use `@Transactional` at the repository interface you define.
+
+.Using @Transactional at query methods
+====
+[source, java]
+----
+@Transactional(readOnly = true)
+public interface UserRepository extends CrudRepository<User, Long> {
+
+  List<User> findByLastname(String lastname);
+
+  @Modifying
+  @Transactional
+  @Query("delete from User u where u.active = false")
+  void deleteInactiveUsers();
+}
+----
+Typically you will want the readOnly flag set to true as most of the query methods will only read data. In contrast to that `deleteInactiveUsers()` makes use of the `@Modifying` annotation and overrides the transaction configuration. Thus the method will be executed with `readOnly` flag set to `false`.
+====
+
+[NOTE]
+====
+It's definitely reasonable to use transactions for read only queries and we can mark them as such by setting the `readOnly` flag. This will not, however, act as check that you do not trigger a manipulating query (although some databases reject `INSERT` and `UPDATE` statements inside a read only transaction). The `readOnly` flag instead is propagated as hint to the underlying JDBC driver for performance optimizations.

+[[jdbc.auditing]]
+== JDBC Auditing
+
+In order to activate auditing just add `@EnableJdbcAuditing` to your configuration.
+
+.Activating auditing with Java configuration
+====
+[source, java]
+----
+@Configuration
+@EnableJdbcAuditing
+class Config {
+
+  @Bean
+  public AuditorAware<AuditableUser> auditorProvider() {
+    return new AuditorAwareImpl();
+  }
+}
+----
+====
+
+If you expose a bean of type `AuditorAware` to the `ApplicationContext`, the auditing infrastructure automatically picks it up and uses it to determine the current user to be set on domain types. If you have multiple implementations registered in the `ApplicationContext`, you can select the one to be used by explicitly setting the `auditorAwareRef` attribute of `@EnableJdbcAuditing`.

Subject: [PATCH 0062/2145] DATAJDBC-207 - Default NamingStrategy is now Snake
 Case.

Moved the implementation from the DelimiterNamingStrategy into the NamingStrategy.
Dropped the support for different separators, since there is no good way to support it in the default implementations of an interface.
A getSeparator() method would bleed into the public API.
Also the added value of that flexibility seems limited.

During migration of the various test it became obvious that SqlGeneratorUnitTests was broken since test failures happend on a worker thread not on the main test thread.
This is fixed as well with this commit.

Subject: [PATCH 0064/2145] DATAJDBC-137 - Improve EntityInformation usage.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Moved to both the usage of the newly introduced PersistentEntity.isNew(…) and identifier lookups via PersistentEntity instead of using a custom EntityInformation implementation. JdbcRepositoryFactory now creates a PersistentEntityInformation, SimpleJdbcRepository simply works with a PersistentEntity.

Removed references to EntityInformation (a repository subsystem concept) from the template implementation. Removed BasicJdbcPersistentEntity and its tests entirely. JdbcAuditingEventListener is now using an IsNewAwareAuditingHandler.

Related tickets: DATACMNS-1333.

 No lazy loading or caching is done.
 
-* If you save and entity it gets saved.
-If you don't it doesn't.

 There is no dirty tracking and no session.

 [[jdbc.domain-driven-design]]
 === Domain Driven Design and Relational Databases.
 
-All Spring Data modules are inspired by the concepts of Repository, Aggregate and Aggregate Root from Domain Driven Design.
-These are possibly even more important for Spring Data JDBC because they are to some extend contrary to normal practice when working with relational databases.
+All Spring Data modules are inspired by the concepts of "`repository`", "`aggregate`", and "`aggregate`" root from Domain Driven Design.
+These are possibly even more important for Spring Data JDBC, because they are, to some extent, contrary to normal practice when working with relational databases.
 
-An *Aggregate* is a group of entities that is guaranteed to be consistent between atomic changes to it.
+An aggregate is a group of entities that is guaranteed to be consistent between atomic changes to it.
 A classic example is an `Order` with `OrderItems`.
-A property on `Order`, e.g. `numberOfItems` will be consistent with the actual number of `OrderItems`.
+A property on `Order` (for example, `numberOfItems` is consistent with the actual number of `OrderItems`) remains consistent as changes are made.
 
-References across Aggregates aren't guaranteed to be consistent at all times.
-They are just guaranteed to become eventual consistent.
+References across aggregates are not guaranteed to be consistent at all times.
+They are guaranteed to become consistent eventually.
 
-Each Aggregate has exactly one *Aggregate Root* which is one of the enties of the Aggregate.
-The Aggregate gets only manipulated through methods on that Aggregate Root.
-These are the *atomic changes* mentioned above.
+Each aggregate has exactly one aggregate root, which is one of the entities of the aggregate.
+The aggregate gets manipulated only through methods on that aggregate root.
+These are the atomic changes mentioned earlier.
 
-*Repositories* are an abstraction over a persistent store that look like a collection of all the Aggregates of a certain type.
-For Spring Data in general this means you want to have one `Repository` per Aggregate Root.
-For Spring Data JDBC this means above that: All entities reachable from an Aggregate Root are considered to be part of that Aggregate Root.
-It is expected that no table outside that Aggregate has a foreign key to that table.

Subject: [PATCH 0066/2145] DATAJDBC-102 - Determine the EntityInstantiator to
 be used dynamically.

Replaced the direct use of EntityInstantiator with EntityInstantiators.
Moved it into the MappingContext because instantiation is part of the mapping process.

Original pull request: #68.

Subject: [PATCH 0069/2145] DATAJDBC-137 - Fixes warnings and improves Javadoc.

All packages now use @NoNullApi.
All warnings related to that fixed, except a few cases where upstream annotations are simply wrong.
Added null checks.
Fixed generic types where possible.
Improved Javadoc.
Code Formatting.

Subject: [PATCH 0072/2145] DATAJDBC-232 - Adapt code to changes to support
 immutable entities.

We now treat all properties of an entity mutable and continue to use the reflective PersistentPropertyAccessor implementation to make sure we don't break the old behavior of reflectively mutating immutable objects.

This is a workaround for now and has to be replaced by more exhaustive changes later.

Related tickets: DATACMNS-1322.

Subject: [PATCH 0074/2145] DATAJDBC-235 - Add support for configurable
 conversion.

We now support configurable conversion by introducing CustomConversions and RelationalConverter. CustomConversions is a registry for converters that should be applied on a per-type basis for properties. CustomConversions is typically registered as bean and fed into RelationalMappingContext and the newly introduced RelationalConverter to consider simple types and conversion rules.

RelationalConverter with its implementation BasicRelationalConverter encapsulates conversion infrastructure such as EntityInstantiator, CustomConversions, and MappingContext that is required during relational value conversion. BasicRelationalConverter is responsible for simple value conversion and entity instantiation to pull related code together. It's not in full charge of row result to object mapping as this responsibility remains as part of DataAccessStrategy.

This change supersedes and removes ConversionCustomizer.

Subject: [PATCH 0077/2145] DATAJDBC-227 - Refactored JdbcEntityWriter and
 DbActions.

JdbcEntityWriter and JdbcDeleteEntityWriter now use an iterative approach based on PersistentPropertyPath instead of a recursive one.

DbAction is now split into multiple interfaces representing different variants of actions.
The implementations are simple value types without any implementation inheritance hierarchy.
All elements of a DbAction implementation are not null making usage and construction of instances much easier.

Original pull request: #79.

From 12d539a017c6a831578d8939696e8068d3cecb31 Mon Sep 17 00:00:00 2001
From: Mark Paluch <mpaluch@pivotal.io>
Date: Thu, 19 Jul 2018 15:15:10 +0200
Subject: [PATCH 0078/2145] DATAJDBC-227 - Polishing.

Return List<DbChange<?>> in RelationalEntityWriters so AggregateChange can be assembled in less places to reduce the number of abstractions per method. Change ResultOrException in FunctionCollector to static class so instances no longer retain a reference to their enclosing class. Fix DbAction generics in AggregateChange. Replace simple constructors with Lombok usage. Javadoc, typos, formatting.

Original pull request: #79.

Subject: [PATCH 0080/2145] DATAJDBC-238 -
 JdbcRepositoryFactory.getEntityInformation never returns null.

Instead it throws an exception as this is required by the interface it implements.

Subject: [PATCH 0082/2145] DATAJDBC-233 - Changed API in order to support
 immutable entities.

Note: Immutable entities still aren't supported yet, these are just the API changes plus implementations that work for mutable entities.

The API of DbActions will need further evolution.

Subject: [PATCH 0084/2145] DATAJDBC-243 - Remove JdbcConfiguration import in
 EnableJdbcRepositories.

We now no longer import JdbcConfiguration to prevent bean overrides when creating a configuration class that extends JdbcConfiguration. Using EnableJdbcRepositories requires either an import of the configuration class inside the application code or registration of the required RelationalConverter and RelationalMappingContext beans.

Subject: [PATCH 0091/2145] DATAJDBC-229 - Added UUID.class as simple type.

Also made RelationalMappingContext actually use the JdbcSimpleTypes.

In order for this to work the database needs to be able to handle parameters of type UUID and store them either as such or internally convert them.
Currently no conversion by Spring Data JDBC happens.

Introduced variable for linking to JavaDoc.
Used the `revnumber` in there in order to link to the proper version of the JavaDoc.
Changed package and class names matching the changes of DATAJDBC-226.
Fixed some typos.

Subject: [PATCH 0094/2145] DATAJDBC-241 - Support for immutable entities.

Immutable entities can now be saved and loaded and the immutability will be honored.

This feature is currently limited to a single level of reference.

In order to implement this the logic for updating IDs with those generated from the database got moved out of the DefaultDataAccessStrategy into the AggregateChange.
As part of that move DataAccessStrategy.save now returns a generated id, if available.

Subject: [PATCH 0100/2145] DATAJDBC-251 - Back-reference for dependent entity
 gets properly set.

If a parent DbAction does not offer a generated id, the id of the entity is used instead. This behavior was broken by DATAJDBC-241.

Related tickets: DATAJDBC-241.

Subject: [PATCH 0102/2145] DATAJDBC-252 - Optimize population of (immutable)
 entities to be created.

The entity creation not skips the property population entirely if the metamodel indicates that the instantiation already creates a complete entity. If there's need to actively populate properties, we now correctly skip the ones already consumed by the constructor.

Previously, SimpleJdbcRepository.save(…) returned the original instance as result of the operation. That assumed that the JdbcAggregateOperations would only manipulate that instance, not return a new one. We now properly return the result of the delegating method call.

Subject: [PATCH 0121/2145] DATAJDBC-266 - Entities referenced by 1:1 don't
 need an Id.

The id-property was used to determine if there is an instance at all, or if it was null.
For entities that don't have an id that purpose is now fulfilled by selecting the backreference and checking it against null.

See also: DATAJDBC-223.

Subject: [PATCH 0123/2145] DATAJDBC-246 - Configured Travis CI build for JDK
 9-11.

Upgraded the dependency-plugin.
Configured matrix build for travis, allowing the JDK 11 build to fail.
The failure should go away once the Spring Framework version we use include the fix for SPR-17093.
Removed Jacoco from the build for JDK 10+.

Subject: [PATCH 0127/2145] DATAJDBC-221 - Added AggregateReference for
 references across aggregates.

AggregateReferences can be used to reference other aggregates via their aggregate root without making them part of the referencing aggregate.
I.e. the referenced entities will not be included in SQL statements for the referencing aggregates, apart from their id.

Conversion between AggregateReferences and their ids and vice versa is done by the RelationalConverter.

 = Spring Data JDBC
 
 The primary goal of the http://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use data access technologies. *Spring Data JDBC* offers the popular Repository abstraction based on JDBC.
 
-== This is NOT an ORM
-
-Spring Data JDBC does not try to be an ORM. It is not a competitor to JPA.
-Instead it is more of a construction kit for your personal ORM that you can define the way you like or need it.
-
-This means that it does rather little out of the box.
-But it offers plenty of places where you can put your own logic, or integrate it with the technology of your choice for generating SQL statements.
-
-== The Aggregate Root
-
-Spring Data repositories are inspired by the repository as described in the book Domain Driven Design by Eric Evans.
-One consequence of this is that you should have a repository per Aggregate Root.
-Aggregate Root is another concept from the same book and describes an entity which controls the lifecycle of other entities which together are an Aggregate.
-An Aggregate is a subset of your model which is consistent between method calls to your Aggregate Root.
-
-Spring Data JDBC tries its best to encourage modelling your domain along these ideas.
-
-== Maven Coordinates
-
-[source,xml]
-----
-<dependency>
-    <groupId>org.springframework.data</groupId>
-    <artifactId>spring-data-jdbc</artifactId>
-    <version>1.0.0.BUILD-SNAPSHOT</version>
-</dependency>
-----
+It aims at being conceptually easy.
+In order to achieve this it does NOT offer caching, lazy loading, write behind or many other features of JPA.
+This makes Spring Data JDBC a simple, limited, opinionated ORM.
 
 == Features
 
-=== CRUD operations
-
-In order to use Spring Data JDBC you need the following:
-
-1. An entity with an attribute marked as _id_ using the Spring Data https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
-+
-[source,java]
-----
- public class Person {
-	 @Id
-	 Integer id;
- }
-----
-+
-1. A repository
-+
-[source,java]
-----
-public interface PersonRepository extends CrudRepository<Person, Integer> {}
-----
-+
-1. Add `@EnableJdbcRepositories` to your application context configuration.
-1. Make sure your application context contains a bean of type `DataSource`.
-
-Now you can get an instance of the repository interface injected into your beans and use it:
-
-[source,java]
-----
-@Autowired
-private PersonRepository repository;
-
-public void someMethod() {
-	Person person = repository.save(new Person());
-}
-----
-
-==== Supported types in your entity
-
-Properties of the following types are currently supported:
-
-* all primitive types and their boxed types (`int`, `float`, `Integer`, `Float` ...)
-
-* enums get mapped to their name.
-
-* `String`
-
-* `java.util.Date`, `java.time.LocalDate`, `java.time.LocalDateTime`, `java.time.LocalTime`
-
-and anything your database driver accepts.
-
-* references to other entities, which will be considered a one-to-one relationship.
-The table of the referenced entity is expected to have an additional column named like the table of the referencing entity.
-This name can be changed by implementing `NamingStrategy.getReverseColumnName(JdbcPersistentProperty property)` according to your preferences.
-
-* `Set<some entity>` will be considered a one-to-many relationship.
-The table of the referenced entity is expected to have an additional column named like the table of the referencing entity.
-This name can be changed by implementing `NamingStrategy.getReverseColumnName(JdbcPersistentProperty property)` according to your preferences.
-
-* `Map<simple type, some entity>` will be considered a qualified one-to-many relationship.
-The table of the referenced entity is expected to have two additional columns: One named like the table of the referencing entity for the foreign key and one with the same name and an additional `_key` suffix for the map key.
-This name can be changed by implementing `NamingStrategy.getReverseColumnName(JdbcPersistentProperty property)` and `NamingStrategy.getKeyColumn(JdbcPersistentProperty property)` according to your preferences.
-
-* `List<some entity>` will be mapped like a  `Map<Integer, some entity>`.
-
-The handling of referenced entities is very limited.
-Part of this is because this project is still before its first release.
-
-But another reason is the idea of <<The Aggregate Root,Aggregate Roots>> as described above.
-If you reference another entity that entity is by definition part of your Aggregate.
-So if you remove the reference it will get deleted.
-This also means references will be 1-1 or 1-n, but not n-1 or n-m.
-
-If you are having n-1 or n-m references you are probably dealing with two separate Aggregates.
-References between those should be encoded as simple ids, which should map just fine with Spring Data JDBC.
-
-Also the mapping we offer is very limited for a third reason which already was mentioned at the very beginning of the document: this is not an ORM.
-We will offer ways to plug in your own SQL in various ways.
-But the default mapping itself will stay limited.
-If you want highly customizable mappings which support almost everything one can imagine you will probably be much happier with (Spring Data) JPA,
-which is a very powerful and mature technology.
-
-=== Query annotation
-
-You can annotate a query method with `@Query` to specify a SQL statement to be used for that method.
-You can bind method arguments using named parameters in the SQL statement like in the following example:
-
-[source,java]
-----
-@Query("SELECT * FROM DUMMYENTITY WHERE name  < :upper and name > :lower")
-List<DummyEntity> findByNameRange(@Param("lower") String lower, @Param("upper") String upper);
-----
-
-If you compile your sources with the `-parameters` compiler flag you can omit the `@Param` annotations.
-
-==== Custom RowMapper
-
-You can configure the `RowMapper` to use, using either the `@Query(rowMapperClass = ....)` or you can register a `RowMapperMap` bean and register `RowMapper` per method return type.
-
-[source,java]
-----
-
-@Bean
-RowMapperMap rowMappers() {
-	return new ConfigurableRowMapperMap() //
-		.register(Person.class, new PersonRowMapper()) //
-		.register(Address.class, new AddressRowMapper());
-}
-
-----
-
-When determining the `RowMapper` to use for a method the following steps are followed based on the return type of the method:
-
-1. If the type is a simple type, no `RowMapper` is used.
-    Instead the query is expected to return a single row with a single column and a conversion to the return type is applied to that value.
-
-2. The entity classes in the `RowMapperMap` are iterated until one is found that is a superclass or interface of the return type in question.
-    The `RowMapper` registered for that class is used.
-    Iterating happens in the order of registration, so make sure to register more general types after specific ones.
-
-If applicable, wrapper types like collections or `Optional` are unwrapped.
-Thus, a return type of `Optional<Person>` will use the type `Person` in the steps above.
-
-==== Modifying query
-
-You can mark as a modifying query using the `@Modifying` on query method.
-
-[source,java]
-----
-@Modifying
-@Query("UPDATE DUMMYENTITY SET name = :name WHERE id = :id")
-boolean updateName(@Param("id") Long id, @Param("name") String name);
-----
-
-The return types that can be specified are `void`, `int`(updated record count) and `boolean`(whether record was updated).
-
-=== Id generation
-
-Spring Data JDBC uses the id to identify entities, but also to determine if an entity is new or already existing in the database.
-If the id is `null` or of a primitive type having value `0` or `0.0`, the entity is considered new.
-
-If your database has some autoincrement-column for the id-column, the generated value will get set in the entity after inserting it into the database.
-
-There are few ways to tweak this behavior.
-If you don't like the logic to distinguish between new and existing entities you can implement https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/domain/Persistable.html[`Persistable`] with your entity and overwrite `isNew()` with your own logic.
+* Implementation of CRUD methods for Aggregates.
+* `@Query` annotation
+* Support for transparent auditing (created, last changed)
+* Events for persistence events
+* Possibility to integrate custom repository code
+* JavaConfig based repository configuration by introducing `EnableJdbcRepository`
+* Integration with MyBatis
 
-One important constraint is that after saving an entity the entity shouldn't be _new_ anymore.
-With autoincrement-columns this happens automatically since the id gets set by Spring Data with the value from the id-column.
-If you are not using autoincrement-columns, you can use a `BeforeSave`-listener which sets the id of the entity (see below).
-
-=== NamingStrategy
-
-If you use the standard implementations of `CrudRepository` as provided by Spring Data JDBC, it will expect a certain table structure.
-You can tweak that by providing a https://github.com/spring-projects/spring-data-jdbc/blob/master/src/main/java/org/springframework/data/jdbc/mapping/model/NamingStrategy.java[`NamingStrategy`] in your application context.
-
-In many cases a https://github.com/spring-projects/spring-data-jdbc/blob/master/src/main/java/org/springframework/data/jdbc/mapping/model/DelimiterNamingStrategy.java[`DelimiterNamingStrategy`]
-might be good basis for a custom implementation
-
-=== Events
-
-Spring Data JDBC triggers events which will get published to any matching `ApplicationListener`  in the application context.
-For example, the following listener will get invoked before an Aggregate gets saved.
-
-[source,java]
-----
-@Bean
-public ApplicationListener<BeforeSaveEvent> timeStampingSaveTime() {
-
-	return event -> {
-
-		Object entity = event.getEntity();
-		if (entity instanceof Category) {
-			Category category = (Category) entity;
-			category.timeStamp();
-		}
-	};
-}
-----

-.Available events
-|===
-| Event | When It's Published
-
-| https://github.com/spring-projects/spring-data-jdbc/blob/master/src/main/java/org/springframework/data/jdbc/mapping/event/BeforeDeleteEvent.java[`BeforeDeleteEvent`]
-| before an aggregate root gets deleted.
-
-| https://github.com/spring-projects/spring-data-jdbc/blob/master/src/main/java/org/springframework/data/jdbc/mapping/event/AfterDeleteEvent.java[`AfterDeleteEvent`]
-| after an aggregate root got deleted.
-
-| https://github.com/spring-projects/spring-data-jdbc/blob/master/src/main/java/org/springframework/data/jdbc/mapping/event/BeforeSaveEvent.java[`BeforeSaveEvent`]
-| before an aggregate root gets saved, i.e. inserted or updated but after the decision was made if it will get updated or deleted.
-The event has a reference to an https://github.com/spring-projects/spring-data-jdbc/blob/master/src/main/java/org/springframework/data/jdbc/core/conversion/AggregateChange.java[`AggregateChange`] instance.
-The instance can be modified by adding or removing https://github.com/spring-projects/spring-data-jdbc/blob/master/src/main/java/org/springframework/data/jdbc/core/conversion/DbAction.java[`DbAction`]s.

-| after an aggregate root got created from a database `ResultSet` and all it's property set
-|===
-
-
-=== MyBatis
-
-For each operation in `CrudRepository` Spring Data JDBC will execute multiple statements.
-If there is a https://github.com/mybatis/mybatis-3/blob/master/src/main/java/org/apache/ibatis/session/SqlSessionFactory.java[`SqlSessionFactory`] in the application context, it will be checked if it offers a statement for each step.
-If one is found, that statement will be used (including its configured mapping to an entity).
-
-By default, the name of the statement is constructed by concatenating the fully qualified name of the entity type  with `Mapper.` and a string determining the kind of statement.
-E.g. if an instance of `org.example.User` is to be inserted, Spring Data JDBC will look for a statement named `org.example.UserMapper.insert`.
-
-Upon execution of the statement an instance of [`MyBatisContext`] will get passed as an argument which makes various arguments available to the statement.
-
-[cols="default,default,default,asciidoc"]
-|===
-| Name | Purpose | CrudRepository methods which might trigger this statement | Attributes available in the `MyBatisContext`
-
-| `insert` | Insert for a single entity. This also applies for entities referenced by the aggregate root. | `save`, `saveAll`. |

-==== NamespaceStrategy
-
-You can customize the namespace part of a statement name using https://github.com/spring-projects/spring-data-jdbc/blob/master/src/main/java/org/springframework/data/jdbc/mybatis/NamespaceStrategy.java[`NamespaceStrategy`].
-
-== Features planned for the not too distant future
-
-=== Advanced query annotation support
-
-* projections
-* SpEL expressions
-
-=== MyBatis per method support
-
-The current MyBatis supported is rather elaborate in that it allows to execute multiple statements for a single method call.
-But sometimes less is more, and it should be possible to annotate a method with a simple annotation to identify a SQL statement in a MyBatis mapping to be executed.
-
-== Spring Boot integration

-There is https://github.com/schauder/spring-data-jdbc-boot-starter[preliminary Spring Boot integration].
+== Getting Help
 
-Currently you will need to build it locally.
+If you are new to Spring Data JDBC read the following two articles https://spring.io/blog/2018/09/17/introducing-spring-data-jdbc["Introducing Spring Data JDBC"] and https://spring.io/blog/2018/09/24/spring-data-jdbc-references-and-aggregates["Spring Data JDBC, References, and Aggregates"]
 
-== Getting Help
+There are also examples in the https://github.com/spring-projects/spring-data-examples/tree/master/jdbc[Spring Data Examples] project.
 
-Right now the best source of information is the source code in this repository.
+A very good source of information is the source code in this repository.
 Especially the integration tests (if you are reading this on github, type `t` and then `IntegrationTests.java`)
 
 We are keeping an eye on the (soon to be created) https://stackoverflow.com/questions/tagged/spring-data-jdbc[spring-data-jdbc tag on stackoverflow].

+* Publishing other's private information, such as physical or electronic addresses,
+  without explicit permission
+* Other unethical or unprofessional conduct
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+By adopting this Code of Conduct, project maintainers commit themselves to fairly and consistently applying these principles to every aspect of managing this project. Project maintainers who do not follow or enforce the Code of Conduct may be permanently removed from the project team.
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community.
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting a project maintainer at spring-code-of-conduct@pivotal.io.
+All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances.
+Maintainers are obligated to maintain confidentiality with regard to the reporter of an incident.
+
+This Code of Conduct is adapted from the http://contributor-covenant.org[Contributor Covenant], version 1.3.0, available at http://contributor-covenant.org/version/1/3/0/[contributor-covenant.org/version/1/3/0/].

Subject: [PATCH 0135/2145] #2 - Refactor to functional usage of resources.

DatabaseClient now creates functions. The actual invocation/execution takes place from DefaultFetchFunctions (FetchSpec) to keep stateful resources in the scope of the execution. execute()/executeMany() use Flux.usingWhen/Mono.usingWhen to release connections after their usage.

Subject: [PATCH 0136/2145] #2 - Introduce ConnectionAccessor.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Declare interface exposing inConnection(…) methods to encapsulate types implementing functionality that is applies within a connection scope. Move FetchSpec and SqlResult implementations to top-level types.

Subject: [PATCH 0152/2145] #2 - Use java.lang.Long as fallback Id type.

We now use java.lang.Long as fallback Id type for entities that do not declare an explicit Id property. Previously we used ObjectId which was a left-over from the initial draft of MappingRelationalEntityInformation.

Subject: [PATCH 0155/2145] #2 - Add transactional support.

We now support transaction hosting and transaction management via TransactionalDatabaseClient.

TransactionalDatabaseClient databaseClient = TransactionalDatabaseClient.create(connectionFactory);

Flux<Integer> integerFlux = databaseClient.inTransaction(db -> {

	return db.execute().sql("INSERT INTO legoset (id, name, manual) VALUES($1, $2, $3)") //
			.bind(0, 42055) //
			.bind(1, "SCHAUFELRADBAGGER") //
			.bindNull("$3") //
			.fetch().rowsUpdated();
});

From a5e2a8e61f79e3a3622ae955a638bf703a23d8ca Mon Sep 17 00:00:00 2001

Subject: [PATCH 0158/2145] #2 - Polishing.

Introduce customization hook methods. Rename DefaultTypedGenericExecuteSpec to DefaultTypedExecuteSpec and GenericExecuteSpecSupport to ExecuteSpecSupport as types are not tied to generic execution. Encapsulate fields in DatabaseClient builders.

+= Spring Data JDBC
+
+The primary goal of the http://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use data access technologies. *Spring Data JDBC* offers the popular Repository abstraction based on JDBC.
+
+It aims at being conceptually easy.
+In order to achieve this it does NOT offer caching, lazy loading, write behind or many other features of JPA.
+This makes Spring Data JDBC a simple, limited, opinionated ORM.
+
+== Features
+
+* Implementation of CRUD methods for Aggregates.
+* `@Query` annotation
+* Support for transparent auditing (created, last changed)
+* Events for persistence events
+* Possibility to integrate custom repository code
+* JavaConfig based repository configuration by introducing `EnableJdbcRepository`
+* Integration with MyBatis
+
+== Getting Help
+
+If you are new to Spring Data JDBC read the following two articles https://spring.io/blog/2018/09/17/introducing-spring-data-jdbc["Introducing Spring Data JDBC"] and https://spring.io/blog/2018/09/24/spring-data-jdbc-references-and-aggregates["Spring Data JDBC, References, and Aggregates"]
+
+There are also examples in the https://github.com/spring-projects/spring-data-examples/tree/master/jdbc[Spring Data Examples] project.
+
+A very good source of information is the source code in this repository.
+Especially the integration tests (if you are reading this on github, type `t` and then `IntegrationTests.java`)
+
+We are keeping an eye on the (soon to be created) https://stackoverflow.com/questions/tagged/spring-data-jdbc[spring-data-jdbc tag on stackoverflow].
+
+If you think you found a bug, or have a feature request please https://jira.spring.io/browse/DATAJDBC/?selectedTab=com.atlassian.jira.jira-projects-plugin:summary-panel[create a ticket in our issue tracker].
+
+== Execute Tests
+
+=== Fast running tests
+
+Fast running tests can be executed with a simple
+
+[source]
+----
+mvn test
+----
+
+This will execute unit tests and integration tests using an in-memory database.
+
+=== Running tests with a real database
+
+In order to run the integration tests against a specific database you need to have a local Docker installation available, and then execute.
+
+[source]
+----
+mvn test -Dspring.profiles.active=<databasetype>
+----
+
+This will also execute the unit tests.
+
+Currently the following _databasetypes_ are available:
+
+* hsql (default, does not require a running database)
+* mysql
+* postgres
+* mariadb
+
+=== Run tests with all databases
+
+[source]
+----
+mvn test -Pall-dbs
+----
+
+This will execute the unit tests, and all the integration tests with all the databases we currently support for testing. Running the integration-tests depends on Docker.
+
+== Contributing to Spring Data JDBC
+
+Here are some ways for you to get involved in the community:
+
+* Get involved with the Spring community by helping out on http://stackoverflow.com/questions/tagged/spring-data-jdbc[stackoverflow] by responding to questions and joining the debate.
+* Create https://jira.spring.io/browse/DATAJDBC[JIRA] tickets for bugs and new features and comment and vote on the ones that you are interested in.
+* Github is for social coding: if you want to write code, we encourage contributions through pull requests from http://help.github.com/forking/[forks of this repository]. If you want to contribute code this way, please reference a JIRA ticket as well, covering the specific issue you are addressing.
+* Watch for upcoming articles on Spring by http://spring.io/blog[subscribing] to spring.io.
+
+Before we accept a non-trivial patch or pull request we will need you to https://cla.pivotal.io/sign/spring[sign the Contributor License Agreement]. Signing the contributor’s agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions, and you will get an author credit if we do. If you forget to do so, you'll be reminded when you submit a pull request. Active contributors might be asked to join the core team, and given the ability to merge pull requests.

-The primary goal of the http://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use data access technologies. *Spring Data JDBC* offers the popular Repository abstraction based on JDBC.
+R2DBC is the abbreviation for https://github.com/r2dbc/[Reactive Relational Database Connectivity], an incubator to integrate relational databases using a reactive driver.
 
-It aims at being conceptually easy.
-In order to achieve this it does NOT offer caching, lazy loading, write behind or many other features of JPA.
-This makes Spring Data JDBC a simple, limited, opinionated ORM.
+The state of R2DBC is incubating to evaluate how an reactive integration could look like. To get started, you need a R2DBC driver first.
 
-== Features
+== This is NOT an ORM
 
-* Implementation of CRUD methods for Aggregates.
-* `@Query` annotation
-* Support for transparent auditing (created, last changed)
-* Events for persistence events
-* Possibility to integrate custom repository code
-* JavaConfig based repository configuration by introducing `EnableJdbcRepository`
-* Integration with MyBatis
+Spring Data R2DBC does not try to be an ORM. 
+Instead it is more of a construction kit for your personal reactive relational data access component that you can define the way you like or need it.

-In order to run the integration tests against a specific database you need to have a local Docker installation available, and then execute.
+=== Examples inserting data
 
-[source]
+[source,java]
 ----
-mvn test -Dspring.profiles.active=<databasetype>
+Flux<Integer> ids = databaseClient.insert()
+				.into("legoset")
+				.value("id", 42055)
+				.value("name", "Description")
+				.nullValue("manual", Integer.class)
+				.exchange() //
+				.flatMapMany(it -> it.extract((r, m) -> r.get("id", Integer.class)).all())
+
+Flux<Integer> ids = databaseClient.insert()
+				.into(LegoSet.class)
+				.using(legoSet)
+				.exchange()
+				.flatMapMany(it -> it.extract((r, m) -> r.get("id", Integer.class)).all())
 ----
 
-This will also execute the unit tests.
+=== Examples using reactive repositories
 
-Currently the following _databasetypes_ are available:
+[source,java]
+----
+interface LegoSetRepository extends ReactiveCrudRepository<LegoSet, Integer> {
 
-* hsql (default, does not require a running database)
-* mysql
-* postgres
-* mariadb
+		@Query("SELECT * FROM legoset WHERE name like $1")
+		Flux<LegoSet> findByNameContains(String name);
 
-=== Run tests with all databases
+		@Query("SELECT * FROM legoset WHERE manual = $1")
+		Mono<LegoSet> findByManual(int manual);
+}
+----
+
+=== Examples using transaction control
 
-[source]
+All examples above run with auto-committed transactions. To get group multiple statements within the same transaction or
+control the transaction yourself, you need to use `TransactionalDatabaseClient`:
+
+[source,java]
 ----
-mvn test -Pall-dbs
+TransactionalDatabaseClient databaseClient = TransactionalDatabaseClient.create(connectionFactory);
 ----
 
-This will execute the unit tests, and all the integration tests with all the databases we currently support for testing. Running the integration-tests depends on Docker.
+`TransactionalDatabaseClient` allows multiple flavors of transaction management:
+
+* Participate in ongoing transactions and fall-back to auto-commit mode if there's no active transaction (default).
+* Group multiple statements in a managed transaction using `TransactionalDatabaseClient.inTransaction(…)`.
+* Application-controlled transaction management using `TransactionalDatabaseClient.beginTransaction()`/`commitTransaction()`/`rollbackTransaction()`.
 
-== Contributing to Spring Data JDBC
+Participating in ongoing transactions does not require changes to your application code. Instead, a managed transaction must be hosted by your application container. Transaction control needs to happen there, as well.
+
+**Statement grouping**
+
+[source,java]
+----
+Flux<Integer> rowsUpdated = databaseClient.inTransaction(db -> {
+
+	return db.execute().sql("INSERT INTO legoset (id, name, manual) VALUES($1, $2, $3)") //
+			.bind(0, 42055) //
+			.bind(1, "Description") //
+			.bindNull("$3", Integer.class) //
+			.fetch()
+			.rowsUpdated();
+});
+----
+
+**Application-controlled transaction management**
+
+[source,java]
+----
+Flux<Long> txId = databaseClient.execute().sql("SELECT txid_current();").exchange()
+				.flatMapMany(it -> it.extract((r, md) -> r.get(0, Long.class)).all());
+
+Mono<Void> then = databaseClient.enableTransactionSynchronization(databaseClient.beginTransaction() //
+				.thenMany(txId)) //
+				.then(databaseClient.rollbackTransaction()));
+----
+
+NOTE: Application-controlled transactions must be enabled with `enableTransactionSynchronization(…)`.
+
+== Building from Source
+
+You don't need to build from source to use Spring Data R2DBC (binaries in https://repo.spring.io[repo.spring.io]), but if you want to try out the latest and greatest, Spring Data R2DBC can be easily built with the https://github.com/takari/maven-wrapper[maven wrapper]. You also need JDK 1.8.
+
+[indent=0]
+----
+	$ ./mvnw clean install
+----
+
+If you want to build with the regular `mvn` command, you will need https://maven.apache.org/run-maven/index.html[Maven v3.5.0 or above].
+
+_Also see link:CONTRIBUTING.adoc[CONTRIBUTING.adoc] if you wish to submit pull requests, and in particular please fill out the https://cla.pivotal.io/[Contributor's Agreement] before your first change._

Subject: [PATCH 0175/2145] DATAJDBC-258 - Integration test support for MS SQL
 Server added.

This adds MS-SQL-Server via Testcontainers to the set of databases available for integration testing.
For this purpose it accepts the EULA of MS SQL Server.

Failing tests are ignored to be fixed in separate issues.

Original pull request: #98.

Subject: [PATCH 0185/2145] #15 - Add BindMarkers abstraction.

We now expose a bind marker API that allows to model a vendor-specific bind marker strategy. The currently supported database systems (Postgres, MsSql) implement indexed respective named strategies that differ in how placeholders and identifiers are generated.

Original pull request: #19.

Subject: [PATCH 0187/2145] #13 - Add @EnableR2dbcRepositories.

We now provide an annotation-based activation model for R2DBC repositories. Configuration classes can be annotated with @EnableR2dbcRepositories and configuration infrastructure will scan for bean definitions to implement declared R2DBC repositories.

Original pull request: #17.

Subject: [PATCH 0193/2145] #20 - Add Dialect initial support for H2,
 PostgreSQL, and Microsoft SQL Server.

We now provide dialect support for H2, PostgreSQL, and Microsoft SQL Server databases, configurable through AbstractR2dbcConfiguration. By default, we obtain the Dialect by inspecting ConnectionFactoryMetadata to identify the database and the most likely dialect to use.

BindableOperation encapsulates statements/queries that can accept parameters. Use BindableOperation for statements through DatabaseClient.
Extract SQL creation.

Split integration test into abstract base class that can be implemented with a database-specific test class.

Original pull request: #24.

Subject: [PATCH 0194/2145] #20 - Polishing.

Rename Database.latestDialect() to defaultDialect(). Rename Dialect.returnGeneratedKeys() to Dialect.generatedKeysClause(). Simplify IndexBindMarkers. Create BindableOperation.bind(Statement, SettableValue) to reduce code duplicates. Rename BindSpecWrapper to BindSpecAdapter.

Original pull request: #24.

+= Preface
+
+The Spring Data R2DBC project applies core Spring concepts to the development of solutions that use the https://r2dbc.io[R2DBC] drivers for relational databases.
+We provide a `DatabaseClient` as a high-level abstraction for storing and querying rows.
+
+This document is the reference guide for Spring Data - R2DBC Support.
+It explains R2DBC module concepts and semantics and.
+
+This section provides some basic introduction to Spring and databases.
+[[get-started:first-steps:spring]]
+== Learning Spring
+
+Spring Data uses Spring framework's http://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/core.html[core] functionality, including:
+
+* http://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/core.html#beans[IoC] container
+* http://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/core.html#validation[type conversion system]
+* http://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/core.html#expressions[expression language]
+* http://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/integration.html#jmx[JMX integration]
+* http://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/data-access.html#dao-exceptions[DAO exception hierarchy].
+
+While you need not know the Spring APIs, understanding the concepts behind them is important.
+At a minimum, the idea behind Inversion of Control (IoC) should be familiar, and you should be familiar with whatever IoC container you choose to use.
+
+The core functionality of the R2DBC support can be used directly, with no need to invoke the IoC services of the Spring Container.
+This is much like `JdbcTemplate`, which can be used "'standalone'" without any other services of the Spring container.
+To leverage all the features of Spring Data R2DBC, such as the repository support, you need to configure some parts of the library to use Spring.
+
+To learn more about Spring, you can refer to the comprehensive documentation that explains the Spring Framework in detail.
+There are a lot of articles, blog entries, and books on the subject.
+See the Spring framework http://spring.io/docs[home page] for more information.
+
+[[get-started:first-steps:what]]
+== What is R2DBC?
+
+https://r2dbc.io[R2DBC] is the acronym for Reactive Relational Database Connectivity. R2DBC is an API specification initiative that declares a reactive API to be implemented by driver vendors for accessing their relational databases.
+
+Part of the answer why R2DBC was created is the need for a non-blocking application stack to handle concurrency with a small number of threads and scale with fewer hardware resources.
+This need cannot be satisfied with reusing standardized relational database access APIs - namely JDBC – as JDBC is a fully blocking API.
+Attempts to compensate for blocking behavior with a `ThreadPool` are limited useful.
+
+The other part of the answer is that most applications use a relational database to store their data.
+While several NoSQL database vendors provide reactive database clients for their databases, migration to NoSQL is not an option for most projects.
+This was the motivation for a new common API to serve as a foundation for any non-blocking database driver.
+While the open source ecosystem hosts various non-blocking relational database driver implementations, each client comes with a vendor-specific API so a generic layer on top of these libraries is not possible.
+
+[[get-started:first-steps:reactive]]
+== What is Reactive?
+
+The term, reactive refers to programming models that are built around reacting to change, availability, and processability — network components reacting to I/O events, UI controllers reacting to mouse events, resources being made available and others.
+In that sense, non-blocking is reactive, because, instead of being blocked, we are now in the mode of reacting to notifications as operations complete or data becomes available.
+
+There is also another important mechanism that we on the Spring team associate with reactive and that is non-blocking back pressure.
+In synchronous, imperative code, blocking calls serve as a natural form of back pressure that forces the caller to wait.
+In non-blocking code, it becomes important to control the rate of events so that a fast producer does not overwhelm its destination.
+
+Reactive Streams is a https://github.com/reactive-streams/reactive-streams-jvm/blob/v{reactiveStreamsVersion}/README.md#specification[small spec] (also https://docs.oracle.com/javase/9/docs/api/java/util/concurrent/Flow.html[adopted] in Java 9) that defines the interaction between asynchronous components with back pressure.
+For example a data repository (acting as {reactiveStreamsJavadoc}/org/reactivestreams/Publisher.html[`Publisher`]) can produce data that an HTTP server (acting as {reactiveStreamsJavadoc}/org/reactivestreams/Subscriber.html`[`Subscriber`]) can then write to the response.
+The main purpose of Reactive Streams is to let the subscriber to control how quickly or how slowly the publisher produces data.
+
+[[get-started:first-steps:reactive-api]]
+== Reactive API
+
+Reactive Streams plays an important role for interoperability. It is of interest to libraries and infrastructure components but less useful as an application API, because it is too low-level.
+Applications need a higher-level and richer, functional API to compose async logic — similar to the Java 8 Stream API but not only for tables.
+This is the role that reactive libraries play.
+
+https://github.com/reactor/reactor[Project Reactor] is the reactive library of choice for Spring Data R2DBC.
+It provides the https://projectreactor.io/docs/core/release/api/reactor/core/publisher/Mono.html[`Mono`] and https://projectreactor.io/docs/core/release/api/reactor/core/publisher/Flux.html[`Flux`] API types to work on data sequences of `0..1` (`Mono`) and `0..N` (`Flux`) through a rich set of operators aligned with the ReactiveX vocabulary of operators.
+Reactor is a Reactive Streams library and, therefore, all of its operators support non-blocking back pressure.
+Reactor has a strong focus on server-side Java. It is developed in close collaboration with Spring.
+
+Spring Data R2DBC requires Project Reactor as a core dependency but it is interoperable with other reactive libraries via Reactive Streams.
+As a general rule, a Spring Data R2DBC repository accepts a plain `Publisher` as input, adapts it to a Reactor type internally, uses that, and returns either a `Mono` or a `Flux` as output.
+So, you can pass any `Publisher` as input and you can apply operations on the output, but you need to adapt the output for use with another reactive library.
+Whenever feasible, Spring Data adapts transparently to the use of RxJava or another reactive library.
+
+[[requirements]]

+[[mapping-chapter]]
+= Mapping
+
+Rich mapping support is provided by the `MappingR2dbcConverter`. `MappingR2dbcConverter` has a rich metadata model that allows to map domain objects to a data row.
+The mapping metadata model is populated by using annotations on your domain objects.
+However, the infrastructure is not limited to using annotations as the only source of metadata information.
+The `MappingR2dbcConverter` also lets you map objects to rows without providing any additional metadata, by following a set of conventions.
+
+This section describes the features of the `MappingR2dbcConverter`, including how to use conventions for mapping objects to rows and how to override those conventions with annotation-based mapping metadata.
+
+[[mapping-conventions]]
+== Convention-based Mapping
+
+`MappingR2dbcConverter` has a few conventions for mapping objects to rows when no additional mapping metadata is provided.
+The conventions are:
+
+* The short Java class name is mapped to the table name in the following manner.
+The class `com.bigbank.SavingsAccount` maps to the `savings_account` table name.
+
+* Nested objects are not supported.
+
+* The converter uses any Spring Converters registered with it to override the default mapping of object properties to row columns and values.
+
+* The fields of an object are used to convert to and from columns in the row.
+Public `JavaBean` properties are not used.
+
+* If you have a single non-zero-argument constructor whose constructor argument names match top-level column names of the row, that constructor is used.
+Otherwise, the zero-argument constructor is used.
+If there is more than one non-zero-argument constructor, an exception will be thrown.
+
+[[mapping-usage]]
+== Metadata-based Mapping
+
+To take full advantage of the object mapping functionality inside the Spring Data R2DBC support, you should annotate your mapped objects with the `@Table` annotation.
+Although it is not necessary for the mapping framework to have this annotation (your POJOs are mapped correctly, even without any annotations), it lets the classpath scanner find and pre-process your domain objects to extract the necessary metadata.
+If you do not use this annotation, your application takes a slight performance hit the first time you store a domain object, because the mapping framework needs to build up its internal metadata model so that it knows about the properties of your domain object and how to persist them.
+The following example shows a domain object:
+
+.Example domain object
+====
+[source,java]
+----
+package com.mycompany.domain;
+
+@Table
+public class Person {
+
+  @Id
+  private Long id;
+
+  private Integer ssn;
+
+  private String firstName;
+
+  @Indexed
+  private String lastName;
+}
+----
+====
+
+IMPORTANT: The `@Id` annotation tells the mapper which property you want to use for the primary key property.
+
+
+[[mapping-usage-annotations]]
+=== Mapping Annotation Overview
+
+The `MappingR2dbcConverter` can use metadata to drive the mapping of objects to rows. The following annotations are available:
+
+* `@Id`: Applied at the field level to mark the primary used for identity purpose.
+* `@Table`: Applied at the class level to indicate this class is a candidate for mapping to the database. You can specify the name of the table where the database will be stored.
+* `@Transient`: By default all private fields are mapped to the row, this annotation excludes the field where it is applied from being stored in the database
+* `@PersistenceConstructor`: Marks a given constructor - even a package protected one - to use when instantiating the object from the database. Constructor arguments are mapped by name to the key values in the retrieved row.
+* `@Column`: Applied at the field level and described the name of the column as it will be represented in the row thus allowing the name to be different than the fieldname of the class.
+
+The mapping metadata infrastructure is defined in a separate spring-data-commons project that is technology agnostic. Specific subclasses are using in the R2DBC support to support annotation based metadata. Other strategies are also possible to put in place if there is demand.
+
+
+[[mapping-custom-object-construction]]
+=== Customized Object Construction
+
+The mapping subsystem allows the customization of the object construction by annotating a constructor with the `@PersistenceConstructor` annotation. The values to be used for the constructor parameters are resolved in the following way:
+
+* If a parameter is annotated with the `@Value` annotation, the given expression is evaluated and the result is used as the parameter value.
+* If the Java type has a property whose name matches the given field of the input row, then it's property information is used to select the appropriate constructor parameter to pass the input field value to. This works only if the parameter name information is present in the java `.class` files which can be achieved by compiling the source with debug information or using the new `-parameters` command-line switch for javac in Java 8.
+* Otherwise a `MappingException` will be thrown indicating that the given constructor parameter could not be bound.
+
+[source,java]

+class OrderItem {
+
+  private @Id String id;
+  private int quantity;
+  private double unitPrice;
+
+  OrderItem(String id, int quantity, double unitPrice) {
+    this.id = id;
+    this.quantity = quantity;
+    this.unitPrice = unitPrice;
+  }
+
+  // getters/setters ommitted

+= R2DBC Repositories
+
+[[r2dbc.repositories.intro]]
+== Introduction
+
+This chapter points out the specialties for repository support for R2DBC.
+This chapter builds on the core repository support explained in <<repositories>>.
+Before reading this chapter, you should have a sound understanding of the basic concepts explained there.
+
+[[r2dbc.repositories.usage]]
+== Usage
+
+To access domain entities stored in a relational database, you can use our sophisticated repository support that eases implementation quite significantly.
+To do so, create an interface for your repository, as the following example shows:
+
+.Sample Person entity
+====
+[source,java]
+----
+public class Person {
+
+  @Id
+  private Long id;
+  private String firstname;
+  private String lastname;
+
+  // … getters and setters omitted
+}
+----
+====
+
+.Basic repository interface to persist Person entities
+====
+[source]
+----
+public interface PersonRepository extends ReactiveCrudRepository<Person, Long> {
+
+  // additional custom query methods go here
+}
+----
+====
+
+Right now, this interface serves only to provide type information, but we can add additional methods to it later.
+To configure R2DBC repositories, you can use the `@EnableR2dbcRepositories` annotation.
+If no base package is configured, the infrastructure scans the package of the annotated configuration class.
+The following example shows how to use Java configuration for a repository:
+
+.Java configuration for repositories
+====
+[source,java]
+----
+@Configuration
+@EnableR2dbcRepositories
+class ApplicationConfig extends AbstractR2dbcConfiguration {
+
+  @Override
+  public ConnectionFactory connectionFactory() {
+    return …;
+  }
+}
+----
+====
+
+Because our domain repository extends `ReactiveCrudRepository`, it provides you with CRUD operations to access the entities.
+Working with the repository instance is just a matter of dependency injecting it into a client.
+Consequently, you can retrieve all `Person` objects would resemble the following code:
+
+.Paging access to Person entities
+====
+[source,java]
+----
+@RunWith(SpringRunner.class)
+@ContextConfiguration
+public class PersonRepositoryTests {
+
+    @Autowired PersonRepository repository;
+
+    @Test
+    public void readsallEntitiesCorrectly() {
+
+      repository.findAll()
+                .as(StepVerifier::create)
+                .expectNextCount(1)
+                .verifyComplete();
+    }
+}
+----
+====
+
+The preceding example creates an application context with Spring's unit test support, which performs annotation-based dependency injection into test cases.
+Inside the test method, we use the repository to query the database.
+We use `StepVerifier` as test aid to verify our expectations against the results.
+
+[[r2dbc.repositories.queries]]
+== Query Methods
+
+Most of the data access operations you usually trigger on a repository result in a query being executed against the databases.
+Defining such a query is a matter of declaring a method on the repository interface, as the following example shows:
+
+.PersonRepository with query methods
+====
+[source,java]
+----
+public interface PersonRepository extends ReactiveCrudRepository<Person, Long> {
+
+    @Query("SELECT * FROM person WHERE lastname = $1")
+    Flux<Person> findByLastname(String lastname);                      <1>
+
+    @Query("SELECT firstname, lastname FROM person WHERE lastname = $1")
+    Mono<Person> findFirstByLastname(String lastname)                  <2>
+
+}
+----
+<1> The `findByLastname` method shows a query for all people with the given last name.
+The query is provided as R2DBC repositories do not support query derivation.
+The annotated query uses native bind markers, which are Postgres bind markers in this example.
+<4> A query for a single `Person` entity projecting only `firstname` and `lastname` columns.
+====
+
+NOTE: R2DBC repositories do not support query derivation.

+[[r2dbc.core]]
+= R2DBC support
+
+The R2DBC support contains a wide range of features:
+
+* Spring configuration support with Java-based `@Configuration` classes  for an R2DBC driver instance.
+* `DatabaseClient` helper class that increases productivity when performing common R2DBC operations with integrated object mapping between rows and POJOs.
+* Exception translation into Spring's portable Data Access Exception hierarchy.
+* Feature-rich Object Mapping integrated with Spring's Conversion Service.
+* Annotation-based mapping metadata that is extensible to support other metadata formats.
+* Automatic implementation of Repository interfaces, including support for custom query methods.
+
+For most tasks, you should use `DatabaseClient` or the Repository support, which both leverage the rich mapping functionality.
+`DatabaseClient` is the place to look for accessing functionality such as ad-hoc CRUD operations.
+
+[[r2dbc.getting-started]]
+== Getting Started
+
+An easy way to bootstrap setting up a working environment is to create a Spring-based project through https://start.spring.io[start.spring.io].
+
+.Add the following to the pom.xml files `dependencies` element:
++
+[source,xml,subs="+attributes"]
+----
+<dependencies>
+
+  <!-- other dependency elements omitted -->
+
+  <dependency>
+    <groupId>org.springframework.data</groupId>
+    <artifactId>spring-data-r2dbc</artifactId>
+    <version>{version}</version>
+  </dependency>
+
+  <!-- a R2DBC driver -->
+  <dependency>
+    <groupId>io.r2dbc</groupId>
+    <artifactId>…</artifactId>
+    <version>{r2dbcVersion}</version>
+  </dependency>
+
+</dependencies>
+----
+. Change the version of Spring in the pom.xml to be
++
+[source,xml,subs="+attributes"]
+----
+<spring.framework.version>{springVersion}</spring.framework.version>
+----
+. Add the following location of the Spring Milestone repository for Maven to your `pom.xml` such that it is at the same level of your `<dependencies/>` element:
++
+[source,xml]
+----
+<repositories>
+  <repository>
+    <id>spring-milestone</id>
+    <name>Spring Maven MILESTONE Repository</name>
+    <url>http://repo.spring.io/libs-milestone</url>
+  </repository>
+</repositories>
+----
+
+The repository is also http://repo.spring.io/milestone/org/springframework/data/[browseable here].
+
+You may also want to set the logging level to `DEBUG` to see some additional information. To do so, edit the `application.properties` file to have the following content:
+
+[source]
+----
+logging.level.org.springframework.data.r2dbc=DEBUG
+----
+
+Then you can create a `Person` class to persist:
+
+[source,java]
+----
+package org.spring.r2dbc.example;
+
+public class Person {
+
+  private String id;
+  private String name;
+  private int age;
+
+  public Person(String id, String name, int age) {
+    this.id = id;
+    this.name = name;
+    this.age = age;
+  }
+
+  public String getId() {
+    return id;
+  }
+  public String getName() {
+    return name;
+  }
+  public int getAge() {
+    return age;
+  }
+
+  @Override
+  public String toString() {
+    return "Person [id=" + id + ", name=" + name + ", age=" + age + "]";
+  }
+}
+----
+
+Next, you need to create a table structure in your database:
+
+[source,sql]
+----
+CREATE TABLE person
+  (id VARCHAR(255) PRIMARY KEY,
+   name VARCHAR(255),
+   age INT);
+----
+
+You also need a main application to run:
+
+[source,java]
+----
+package org.spring.r2dbc.example;
+
+public class R2dbcApp {
+
+  private static final Log log = LogFactory.getLog(R2dbcApp.class);
+
+  public static void main(String[] args) throws Exception {
+
+    ConnectionFactory connectionFactory = new H2ConnectionFactory(H2ConnectionConfiguration.builder()
+                                                                    .url("/service/mem:test;DB_CLOSE_DELAY=10")
+                                                                    .build());
+
+    DatabaseClient client = DatabaseClient.create(connectionFactory);
+
+    client.execute()
+            .sql("CREATE TABLE person" +
+                    "  (id VARCHAR(255) PRIMARY KEY," +
+                    "   name VARCHAR(255)," +
+                    "   age INT)")
+            .fetch()
+            .rowsUpdated()
+            .as(StepVerifier::create)
+            .expectNextCount(1)
+            .verifyComplete();
+
+    client.insert()
+            .into(Person.class)
+            .using(new Person("joe", "Joe", 34))
+            .then()
+            .as(StepVerifier::create)
+            .verifyComplete();
+
+    client.select()
+            .from(Person.class)
+            .fetch()
+            .first()
+            .doOnNext(it -> log.info(it))
+            .as(StepVerifier::create)
+            .expectNextCount(1)
+            .verifyComplete();
+  }
+}
+----
+
+When you run the main program, the preceding examples produce the following output:
+
+[source]

+----
+
+Even in this simple example, there are few things to notice:
+
+* You can create an instance of the central helper class in Spring Data R2DBC, <<r2dbc.datbaseclient,`DatabaseClient`>>, by using a standard `io.r2dbc.spi.ConnectionFactory` object.
+* The mapper works against standard POJO objects without the need for any additional metadata (though you can optionally provide that information. See <<mapping-chapter,here>>.).
+* Mapping conventions can use field access. Notice that the `Person` class has only getters.
+* If the constructor argument names match the column names of the stored row, they are used to instantiate the object.

+== Examples Repository
+
+There is a https://github.com/spring-projects/spring-data-examples[GitHub repository with several examples] that you can download and play around with to get a feel for how the library works.
+
+[[r2dbc.drivers]]
+== Connecting to a Relational Database with Spring
+
+One of the first tasks when using relational databases and Spring is to create a `io.r2dbc.spi.ConnectionFactory` object using the IoC container. The following example explains Java-based configuration.
+
+[[r2dbc.connectionfactory]]
+=== Registering a `ConnectionFactory` Instance using Java-based Metadata
+
+The following example shows an example of using Java-based bean metadata to register an instance of a `io.r2dbc.spi.ConnectionFactory`:
+
+.Registering a `io.r2dbc.spi.ConnectionFactory` object using Java-based bean metadata
+====
+[source,java]
+----
+@Configuration
+public class ApplicationConfiguration extends AbstractR2dbcConfiguration {
+
+  @Override
+  @Bean
+  public ConnectionFactory connectionFactory() {
+    return …;
+  }
+}
+----
+====
+
+This approach lets you use the standard `io.r2dbc.spi.ConnectionFactory` instance, with the container using Spring's `AbstractR2dbcConfiguration`. As compared to registering a `ConnectionFactory` instance directly, the configuration support has the added advantage of also providing the container with an `ExceptionTranslator` implementation that translates R2DBC exceptions to exceptions in Spring's portable `DataAccessException` hierarchy for data access classes annotated with the `@Repository` annotation. This hierarchy and the use of `@Repository` is described in http://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/data-access.html[Spring's DAO support features].
+
+`AbstractR2dbcConfiguration` registers also `DatabaseClient` that is required for database interaction and for Repository implementation.
+
+[[r2dbc.drivers]]
+=== R2DBC Drivers
+
+Spring Data R2DBC supports drivers by R2DBC's pluggable SPI mechanism. Any driver implementing the R2DBC spec can be used with Spring Data R2DBC.
+R2DBC is a relatively young initiative that gains significance by maturing through adoption.
+As of writing the following 3 drivers are available:
+
+* https://github.com/r2dbc/r2dbc-postgresql[Postgres] (`io.r2dbc:r2dbc-postgresql`)
+* https://github.com/r2dbc/r2dbc-h2[H2] (`io.r2dbc:r2dbc-h2`)
+* https://github.com/r2dbc/r2dbc-mssql[Microsoft SQL Server] (`io.r2dbc:r2dbc-mssql`)
+
+Spring Data R2DBC reacts to database specifics by inspecting `ConnectionFactoryMetadata` and selects the appropriate database dialect.
+You can configure an own `Dialect` if the used driver is not yet known to Spring Data R2DBC.
+
+[[r2dbc.datbaseclient]]
+== Introduction to `DatabaseClient`
+
+Spring Data R2DBC includes a reactive, non-blocking `DatabaseClient` for database interaction. The client has a functional, fluent API with reactive types for declarative composition.
+`DatabaseClient` encapsulates resource handling such as opening and closing connections so your application code can make use of executing SQL queries or calling higher-level functionality such as inserting or selecting data.
+
+NOTE: `DatabaseClient` is a young application component providing a minimal set of convenience methods that is likely to be extended through time.
+
+NOTE: Once configured, `DatabaseClient` is thread-safe and can be reused across multiple instances.
+
+Another central feature of `DatabaseClient` is translation of exceptions thrown by R2DBC drivers into Spring's portable Data Access Exception hierarchy. See "`<<r2dbc.exception>>`" for more information.
+
+The next section contains an example of how to work with the `DatabaseClient` in the context of the Spring container.
+
+[[r2dbc.datbaseclient.create]]
+=== Creating `DatabaseClient`
+
+The simplest way to create a `DatabaseClient` is through a static factory method:
+
+[source,java]
+----
+DatabaseClient.create(ConnectionFactory connectionFactory)
+----
+
+The above method creates a `DatabaseClient` with default settings.
+
+You can also use `DatabaseClient.builder()` with further options to customize the client:
+
+* `exceptionTranslator`: Supply a specific `R2dbcExceptionTranslator` to customize how R2DBC exceptions are translated into Spring's portable Data Access Exception hierarchy.  See "`<<r2dbc.exception>>`" for more information.
+* `dataAccessStrategy`: Strategy how SQL queries are generated and how objects are mapped.
+
+Once built, a `DatabaseClient` instance is immutable. However, you can clone it and build a modified copy without affecting the original instance, as the following example shows:
+
+[source,java]
+----
+DatabaseClient client1 = DatabaseClient.builder()
+        .exceptionTranslator(exceptionTranslatorA).build();
+
+DatabaseClient client2 = client1.mutate()
+        .exceptionTranslator(exceptionTranslatorB).build();
+----
+
+=== Controlling Database Connections
+
+Spring Data R2DBC obtains a connection to the database through a `ConnectionFactory`.
+A `ConnectionFactory` is part of the R2DBC specification and is a generalized connection factory.
+It lets a container or a framework hide connection pooling and transaction management issues from the application code.
+
+When you use Spring Data R2DBC, you can create a `ConnectionFactory` using your R2DBC driver.
+`ConnectionFactory` implementations can either return the same connection, different connections or provide connection pooling.
+`DatabaseClient` uses `ConnectionFactory` to create and release connections per operation without affinity to a particular connection across multiple operations.
+
+[[r2dbc.exception]]
+== Exception Translation
+
+The Spring framework provides exception translation for a wide variety of database and mapping technologies.
+This has traditionally been for JDBC and JPA. The Spring support for R2DBC extends this feature by providing implementations of the `R2dbcExceptionTranslator` interface.
+
+`R2dbcExceptionTranslator` is an interface to be implemented by classes that can translate between `R2dbcException` and Spring’s own `org.springframework.dao.DataAccessException`, which is agnostic in regard to data access strategy.
+Implementations can be generic (for example, using SQLState codes) or proprietary (for example, using Postgres error codes) for greater precision.
+
+`SqlErrorCodeR2dbcExceptionTranslator` is the implementation of `R2dbcExceptionTranslator` that is used by default.
+This implementation uses specific vendor codes.
+It is more precise than the SQLState implementation.
+The error code translations are based on codes held in a JavaBean type class called `SQLErrorCodes`.
+This class is created and populated by an `SQLErrorCodesFactory`, which (as the name suggests) is a factory for creating SQLErrorCodes based on the contents of a configuration file named `sql-error-codes.xml` from Spring's Data Access module.
+This file is populated with vendor codes and based on the `ConnectionFactoryName` taken from `ConnectionFactoryMetadata`.
+The codes for the actual database you are using are used.
+
+The `SqlErrorCodeR2dbcExceptionTranslator` applies matching rules in the following sequence:
+
+1. Any custom translation implemented by a subclass. Normally, the provided concrete `SqlErrorCodeR2dbcExceptionTranslator` is used, so this rule does not apply. It applies only if you have actually provided a subclass implementation.
+2. Any custom implementation of the `SQLExceptionTranslator` interface that is provided as the `customSqlExceptionTranslator` property of the `SQLErrorCodes` class.
+3. Error code matching is applied.
+4. Use a fallback translator.
+
+
+NOTE: The `SQLErrorCodesFactory` is used by default to define Error codes and custom exception translations. They are looked up in a file named `sql-error-codes.xml` from the classpath, and the matching `SQLErrorCodes` instance is located based on the database name from the database metadata of the database in use. `SQLErrorCodesFactory` is as of now part of Spring JDBC. Spring Data R2DBC reuses existing translation configurations.
+
+You can extend `SqlErrorCodeR2dbcExceptionTranslator`, as the following example shows:
+
+[source,java]
+----
+public class CustomSqlErrorCodeR2dbcExceptionTranslator extends SqlErrorCodeR2dbcExceptionTranslator {
+
+    protected DataAccessException customTranslate(String task, String sql, R2dbcException r2dbcex) {
+        if (sqlex.getErrorCode() == -12345) {
+            return new DeadlockLoserDataAccessException(task, r2dbcex);
+        }
+        return null;
+    }
+}
+----
+
+In the preceding example, the specific error code (`-12345`) is translated, while other errors are left to be translated by the default translator implementation.
+To use this custom translator, you must configure `DatabaseClient` through the builder method `exceptionTranslator`, and you must use this `DatabaseClient` for all of the data access processing where this translator is needed.
+The following example shows how you can use this custom translator:
+
+[source,java]
+----
+ConnectionFactory connectionFactory = …;
+
+CustomSqlErrorCodeR2dbcExceptionTranslator exceptionTranslator = new CustomSqlErrorCodeR2dbcExceptionTranslator();
+
+DatabaseClient client = DatabaseClient.builder()
+                            .connectionFactory(connectionFactory)
+                            .exceptionTranslator(exceptionTranslator)
+                            .build();
+----
+
+[[r2dbc.datbaseclient.statements]]
+=== Running Statements
+
+Running a statement is the basic functionality that is covered by `DatabaseClient`.
+The following example shows what you need to include for a minimal but fully functional class that creates a new table:
+
+[source,java]
+----
+Mono<Void> completion = client.execute()
+        .sql("CREATE TABLE person (id VARCHAR(255) PRIMARY KEY, name VARCHAR(255), age INTEGER);")
+        .then();
+----
+
+`DatabaseClient` is designed for a convenient fluent usage.
+It exposes intermediate, continuation, and terminal methods at each stage of the execution specification.
+The example above uses `then()` to return a completion `Publisher` that completes as soon as the query (or queries, if the SQL query contains multiple statements) completes.
+
+NOTE: `execute().sql(…)` accepts either the SQL query string or a query `Supplier<String>` to defer the actual query creation until execution.
+
+[[r2dbc.datbaseclient.queries]]
+=== Running Queries
+
+SQL queries can return values or the number of affected rows.
+`DatabaseClient` can return the number of updated rows or the rows themself, depending on the issued query.
+
+The following example shows an `UPDATE` statement that returns the number of updated rows:
+
+[source,java]
+----
+Mono<Integer> affectedRows = client.execute()
+        .sql("UPDATE person SET name = 'Joe'")
+        .fetch().rowsUpdated();
+----
+
+Running a `SELECT` query returns a different type of result, in particular tabular results. Tabular data is typically consumes by streaming each `Row`.
+You might have noticed the use of `fetch()` in the previous example.
+`fetch()` is a continuation operator that allows you to specify how much data you want to consume.
+
+[source,java]
+----
+Mono<Map<String, Object>> first = client.execute()
+        .sql("SELECT id, name FROM person")
+        .fetch().first();
+----
+
+Calling `first()` returns the first row from the result and discards remaining rows.
+You can consume data with the following operators:
+
+* `first()` return the first row of the entire result
+* `one()` returns exactly one result and fails if the result contains more rows.
+* `all()` returns all rows of the result
+* `rowsUpdated()` returns the number of affected rows (`INSERT` count, `UPDATE` count)
+
+`DatabaseClient` queries return their results by default as `Map` of column name to value. You can customize type mapping by applying an `as(Class<T>)` operator.
+
+[source,java]
+----
+Flux<Person> all = client.execute()
+        .sql("SELECT id, name FROM mytable")
+        .as(Person.class)
+        .fetch().all();
+----
+
+`as(…)` applies <<mapping-conventions,Convention-based Object Mapping>> and maps the resulting columns to your POJO.
+
+[[r2dbc.datbaseclient.mapping]]
+=== Mapping Results
+
+You can customize result extraction beyong `Map` and POJO result extraction by providing an extractor `BiFunction<Row, RowMetadata, T>`.
+The extractor function interacts directly with R2DBC's `Row` and `RowMetadata` objects and can return arbitrary values (singular values, collections/maps, objects).
+
+The following example extracts the `id` column and emits its value:
+
+[source,java]
+----
+Flux<String> names= client.execute()
+        .sql("SELECT name FROM person")
+        .fetch()
+        .extract((row, rowMetadata) -> row.get("id", String.class))
+        .all();
+----
+
+[[r2dbc.datbaseclient.mapping.null]]
+.What about `null`?
+****
+Relational database results may contain `null` values.
+Reactive Streams forbids emission of `null` values which requires a proper `null` handling in the extractor function.
+While you can obtain `null` values from a `Row`, you must not emit a `null` value.
+You must wrap any `null` values in an object (e.g. `Optional` for singular values) to make sure a `null` value is never returned directly by your extractor function.
+****
+
+[[r2dbc.datbaseclient.binding]]
+=== Binding Values to Queries
+
+A typical application requires parametrized SQL statements to select or update rows according to some input.
+These are typically `SELECT` statements  constrained by a `WHERE` clause or `INSERT`/`UPDATE` statements accepting input parameters.
+Parametrized statements bear the risk of SQL injection if parameters are not escaped properly.
+`DatabaseClient` leverages R2DBC's Bind API to eliminate the risk of SQL injection for query parameters.
+You can provide a parametrized SQL statement with the `sql(…)` operator and bind parameters to the actual `Statement`.
+Your R2DBC driver then executes the statement using prepared statements and parameter substitution.
+
+Parameter binding supports various binding strategies:
+
+* By Index using zero-based parameter indexes.
+* By Name using the placeholder name.
+
+The following example shows parameter binding for a PostgreSQL query:
+
+[source,java]
+----
+db.execute()
+    .sql("INSERT INTO person (id, name, age) VALUES($1, $2, $3)")
+    .bind(0, "joe")
+    .bind(1, "Joe")
+    .bind(2, 34);
+----
+
+NOTE: If you are familiar with JDBC, then you're also familiar with `?` (questionmark) bind markers.
+JDBC drivers translate questionmark bindmarkers to database-native markers as part of statement execution.
+Make sure to use the appropriate bind markers that are supported by your database as R2DBC requires database-native parameter bind markers.
+
+[[r2dbc.datbaseclient.transactions]]
+=== Transactions
+
+A common pattern when using relational databases is grouping multiple queries within a unit of work that is guarded by a transaction.
+Relational databases typically associate a transaction with a single transport connection.
+Using different connections hence results in utilizing different transactions.
+Spring Data R2DBC includes a transactional `DatabaseClient` implementation with `TransactionalDatabaseClient` that allows you to group multiple statements within the same transaction.
+`TransactionalDatabaseClient` is a extension of `DatabaseClient` that exposes the same functionality as `DatabaseClient` and adds transaction-management methods.
+
+You can run multiple statements within a transaction using the `inTransaction(Function)` closure:
+
+[source,java]
+----
+TransactionalDatabaseClient databaseClient = TransactionalDatabaseClient.create(connectionFactory);
+
+Flux<Void> completion = databaseClient.inTransaction(db -> {
+
+    return db.execute().sql("INSERT INTO person (id, name, age) VALUES($1, $2, $3)") //
+            .bind(0, "joe") //
+            .bind(1, "Joe") //
+            .bind(2, 34) //
+            .fetch().rowsUpdated()
+            .then(db.execute().sql("INSERT INTO contacts (id, name) VALUES($1, $2)")
+                    .bind(0, "joe")
+                    .bind(1, "Joe")
+                    .fetch().rowsUpdated())
+            .then();
+});

DatabaseClient now no longer exposes the exchange() method but rather provides map(…) and then(…) methods.
Calling map(…) extracts values from tabular results by propagating the mapping function to Result.map(…).
then() allows statement execution without returning the result propagating only completion and error signals.

Subject: [PATCH 0202/2145] #8 - Reduce API surface for mapped tabular results.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move retrieval methods from FetchSpec into RowsFetchSpec and UpdatedRowsFetchSpec.

map(…) now returns RowsFetchSpec to not expose updated rows count as mapped results are consumed as objects.

Subject: [PATCH 0205/2145] #30 - Add custom conversion support.

We now support custom conversions via R2dbcCustomConversions.
Custom conversions introduces simple types that depend on the used dialect.
Custom conversions and simple types are held in RelationalConverter and MappingContext.

Simple types and conversions are used by DatabaseClient and repository support to properly apply registered converters and support native types such as array-columns.

Related tickets: #22, #26.
Original pull request: #31.

 Spring Data JDBC Changelog
 =========================
 
+Changes in version 1.1.0.M1 (2018-12-11)
+----------------------------------------
+* DATAJDBC-306 - Simplify reference documentation setup.
+* DATAJDBC-305 - Release 1.1 M1 (Moore).
+* DATAJDBC-301 - Fix Travis build failing due to moved JDK8.
+* DATAJDBC-294 - ID in where clauses doesn't properly considers the NamingStrategy.
+* DATAJDBC-288 - Alter visibility of JdbcConfiguration to support better extensibility.
+* DATAJDBC-286 - Mapping OneToOne relationship broken for immutable entities & PostgreSQL.
+* DATAJDBC-280 - The Travis build is broken due to a broken JDK download.
+* DATAJDBC-276 - AggregateChange.setId requires an ID-attribute for List elements.
+* DATAJDBC-273 - Creating entity via constructor assumes child properties are nested entities.
+* DATAJDBC-272 - Split Spring Data JDBC project into modules.
+* DATAJDBC-271 - Simplify README.
+* DATAJDBC-266 - Referenced entity in one to one relationship requires an id, which it shouldn't.
+* DATAJDBC-263 - When entities get created via a method with @Query annotation no AfterLoadEvent gets triggered.
+* DATAJDBC-262 - Id gets updated.
+* DATAJDBC-258 - Run integration tests with Microsoft SQL Server.
+* DATAJDBC-246 - Make the Travis build run with different JDKs.
+* DATAJDBC-221 - Introduce a Reference type for cross aggregate references.
+* DATAJDBC-125 - support multiple entity references of same type.
+
+
 Changes in version 1.0.3.RELEASE (2018-11-27)
 ---------------------------------------------
 * DATAJDBC-294 - ID in where clauses doesn't properly considers the NamingStrategy.

Subject: [PATCH 0224/2145] DATAJDBC-290 - Reestablish compatibility.

Recreated RowMapperMap, its implementation and related methods in order to not to break existing implementations.
Everything deprecated so we can remove it from 1.2 on.

Original pull request: #101.

 The constructor of `JdbcCustomConversions` accepts a list of `org.springframework.core.convert.converter.Converter`.
 
+Converters should be annotated with `@ReadingConverter` or `@WritingConverter` in order to control their applicability to only reading from or to writing to the database.
+
+`TIMESTAMPTZ` in the example is a database specific data type that needs conversion into something more suitable for a domain model.

Subject: [PATCH 0235/2145] #48 - Atomically close connections.

We now make sure to close connections only once by tracking the cleanup state. Flux.usingWhen/Mono.usingWhen do not ensure atomic cleanup in situations where the subscription completes and then the subscription is terminated.

This behavior has lead to closing a connection multiple times.

Subject: [PATCH 0237/2145] DATAJDBC-282 - Add insert and update methods to
 JdbcRepository.

This introduces the JdbcRepository interface which offers two additional methods beyond the CrudRepository:
`insert` and `update`.
Both methods skip the test if the aggregate is new and perform the respective operation.

Especially `insert` is useful for saving new aggregates which are new but have an ID set by the client and not generated by the database.

Original pull request: #107.

Subject: [PATCH 0239/2145] DATAJDBC-282 - Removed JdbcRepository.

The decision was made not to offer `insert` and `update` as part of the repository interface.

It stays available as part of the `JdbcAggregateTemplate` which may be used directly or inside of a custom method implementation.

 When you use the standard implementations of `CrudRepository` that Spring Data JDBC provides, they expect a certain table structure.
 You can tweak that by providing a {javadoc-base}org/springframework/data/relational/core/mapping/NamingStrategy.html[`NamingStrategy`] in your application context.
 
+[[jdbc.entity-persistence.custom-table-name]]
+=== `Custom table names`
+
+When the NamingStrategy does not matching on your database table names, you can customize the names with the {javadoc-base}org/springframework/data/relational/core/mapping/Table.html[`@Table`] annotation.
+The element `value` of this annotation provides the custom table name. The following example maps the `MyEntity` class to the `CUSTOM_TABLE_NAME` table in the database:
+
+====
+[source, java]
+----
+@Table("CUSTOM_TABLE_NAME")
+public class MyEntity {
+    @Id
+    Integer id;
+
+    String name;
+}
+----
+====
+
+[[jdbc.entity-persistence.custom-column-name]]
+=== `Custom column names`
+
+When the NamingStrategy does not matching on your database column names, you can customize the names with the {javadoc-base}org/springframework/data/relational/core/mapping/Column.html[`@Column`] annotation.
+The element `value` of this annotation provides the custom column name.
+The following example maps the `name` property of the `MyEntity` class to the `CUSTOM_COLUMN_NAME` column in the database:
+
+====
+[source, java]
+----
+public class MyEntity {
+    @Id
+    Integer id;
+
+    @Column("CUSTOM_COLUMN_NAME")
+    String name;
+}
+----
+====
+
+The {javadoc-base}org/springframework/data/relational/core/mapping/Column.html[`@Column`] annotation can also be used on a reference type (one-to-one relationship) or on Sets, Lists, and Maps (one-to-many relationship)
+On all these types the `value` element of the annotation is used to provide a custom name for the id column in the other table.
+In the following example the corresponding table for the `MySubEntity` class has a name column, and the id column of the `MyEntity` id for relationship reasons.
+The name of this `MySubEntity` class's id column can also be customized with the `value` element of the {javadoc-base}org/springframework/data/relational/core/mapping/Column.html[`@Column`] annotation:

+    @Column("CUSTOM_COLUMN_NAME")
+    Set<MySubEntity> name;
+}
+
+public class MySubEntity {
+    String name;
+}
+----
+====
+
+By the using of Lists and Maps you must have an additional column for the position of a dataset in a List or the key value of a dataset in the map.
+This additional column name can be customized with the `keyColumn` Element of the {javadoc-base}org/springframework/data/relational/core/mapping/Column.html[`@Column`] annotation:

The default ("") is equivalent to no annotation at all, i.e. the `NamingStrategy` determines the table name.

Subject: [PATCH 0245/2145] #29 - Use Testcontainers to run Postgres
 integration tests.

Postgres integration tests now run either with a locally installed and started database or if no such database can be found an instance gets started in a Docker container via Testcontainers.

We prefer a database based on TestContainers. Only if this can't be obtained do we try to access a local database for Postgres.

This minimizes the risk of accessing a database during tests that is not intended for that purpose.

If the system property `spring.data.r2dbc.test.preferLocalDatabase` is set to "true" the local database is preferred.

Subject: [PATCH 0247/2145] #23 - Add support for named parameters.

DatabaseClient now supports named parameters prefixed with a colon such as :name in addition to database-native bind markers. Named parameters thus are supported in annotated repository query methods which also increases portability of queries across database vendors.

Named parameter support unrolls collection arguments to reduce the need for argument-specific SQL statements:

db.execute()
    .sql("SELECT id, name, state FROM table WHERE age IN (:ages)")
    .bind("ages", Arrays.asList(35, 50));

Results in a query: SELECT id, name, state FROM table WHERE age IN (35, 50)

Collection arguments containing nested object arrays can be used to use select lists:

List<Object[]> tuples = new ArrayList<>();
tuples.add(new Object[] {"John", 35});
tuples.add(new Object[] {"Ann",  50});

db.execute()
    .sql("SELECT id, name, state FROM table WHERE (name, age) IN (:tuples)")
    .bind("tuples", tuples);

translates to: SELECT id, name, state FROM table WHERE (name, age) IN (('John', 35), ('Ann', 50))

-NOTE: If you are familiar with JDBC, then you're also familiar with `?` (question mark) bind markers.
+.R2DBC Native Bind Markers
+****
+R2DBC uses database-native bind markers that depend on the actual database.
+If you are familiar with JDBC, then you're also familiar with `?` (question mark) bind markers.
 JDBC drivers translate question mark bind markers to database-native markers as part of statement execution.
-Make sure to use the appropriate bind markers that are supported by your database as R2DBC requires database-native parameter bind markers.
+
+Postgres uses indexed markers (`$1`, `$2`), SQL Server uses named bind markers prefixed with `@` as its native bind marker syntax.
+Spring Data R2DBC leverages `Dialect` implementations to expand named parameters to native bind markers at the time of query execution which gives you a certain degree of query portability across various database vendors.
+You can still use native bind markers if you prefer to do so.
+****
+
+The query-preprocessor unrolls named `Collection` parameters into a series of bind markers to remove the need of dynamic query creation based on the number of arguments.
+Nested object arrays are expanded to allow usage of e.g. select lists.
+
+Consider the following query:
+
+[source,sql]
+----
+SELECT id, name, state FROM table WHERE (name, age) IN (('John', 35), ('Ann', 50))
+----
+
+This query can be parametrized and executed as:
+
+[source,java]
+----
+List<Object[]> tuples = new ArrayList<>();
+tuples.add(new Object[] {"John", 35});
+tuples.add(new Object[] {"Ann",  50});
+
+db.execute()
+    .sql("SELECT id, name, state FROM table WHERE (name, age) IN (:tuples)")
+    .bind("tuples", tuples);
+----
+
+NOTE: Usage of select lists is vendor-dependent.
+
+A simpler variant using `IN` predicates:
+
+[source,java]
+----
+db.execute()
+    .sql("SELECT id, name, state FROM table WHERE age IN (:ages)")
+    .bind("ages", Arrays.asList(35, 50));

Subject: [PATCH 0248/2145] #23 - Polishing.

Formatting.
Made Tests simpler and stricter by using `containsExactly`.
Added @Test annotation to ignored database specific tests so they actually show up as ignored.

Original pull request: #47.

 .R2DBC Native Bind Markers
 ****
-R2DBC uses database-native bind markers that depend on the actual database.
-If you are familiar with JDBC, then you're also familiar with `?` (question mark) bind markers.
-JDBC drivers translate question mark bind markers to database-native markers as part of statement execution.
+R2DBC uses database-native bind markers that depend on the actual database vendor.
+As an example, Postgres uses indexed markers such as `$1`, `$2`, `$n`.
+Another example is SQL Server that uses named bind markers prefixed with `@` (at).
 
-Postgres uses indexed markers (`$1`, `$2`), SQL Server uses named bind markers prefixed with `@` as its native bind marker syntax.
-Spring Data R2DBC leverages `Dialect` implementations to expand named parameters to native bind markers at the time of query execution which gives you a certain degree of query portability across various database vendors.
-You can still use native bind markers if you prefer to do so.
+This is different from JDBC which requires `?` (question mark) as bind markers.
+In JDBC, the actual drivers translate question mark bind markers to database-native markers as part of their statement execution.
+
+Spring Data R2DBC allows you to use native bind markers or named bind markers with the `:name` syntax.
+
+Named parameter support leverages ``Dialect``s  to expand named parameters to native bind markers at the time of query execution which gives you a certain degree of query portability across various database vendors.
 ****
 
 The query-preprocessor unrolls named `Collection` parameters into a series of bind markers to remove the need of dynamic query creation based on the number of arguments.

Very likely without the person using this knowing that she is accepting a license.
The file now has to be explicitly provided.

The Travis CI build adds the container-license-acceptance.txt for the build only.

+=== `Embedded entities`
+
+Embedded entities are used to have value objects in your java data model, even if there is only one table in your database.
+In the following example you see, that `MyEntity` is mapped with the `@Embedded` annotation.
+The consequence of this is, that in the database a table `my_entity` with the two columns `id` and `name` (from the `EmbeddedEntity` class) is expected.
+
+====
+[source, java]
+----
+public class MyEntity {
+    @Id
+    Integer id;
+
+    @Embedded
+    EmbeddedEntity embeddedEntity;
+}
+
+public class EmbeddedEntity {
+    String name;
+}
+----
+====
+
+If you need a value object multiple times in an entity, this can be achieved with the optional `value` element of the `@Embedded` annotation.
+This element represents a prefix and is prepend for each column name in the embedded object.

Subject: [PATCH 0259/2145] DATAJDBC-330 - Move default bean lookup from
 JdbcRepositoryConfigExtension to JdbcRepositoryFactoryBean.

So far the lookup of `NamedParameterJdbcOperations` and `DataAccessStrategy` could happend before these beans were registered resulting in failure to consider those beans.

The logic is now split in two parts:
If a bean name is given, this is configured on the BeanDefinition level in the JdbcRepositoryConfigExtension.
If no name is give a bean is looked up by type in the JdbcRepositoryFactoryBean.

This makes the code even simpler and uses standard Spring features instead of reimplementing them.

Original pull request: #115.

Subject: [PATCH 0262/2145] DATAJDBC-259 - Polishing.

Unwrap multi-dimensional array types to determine the proper component type. Extend tests. Inline isCollectionOf[Entities|SimpleType]Like calls and remove utility methods on RelationalPersistentProperty as the usage-scope is specific to array handling.

Subject: [PATCH 0263/2145] DATAJDBC-329 - Replacing JdbcConfiguration.

Reverting breaking changes to JdbcConfiguration.
Deprecating JdbcConfiguration in favor of AbstractJdbcConfiguration.
Cleaning up the API to separate it from spring-data-relational and therefore R2DBC.

Subject: [PATCH 0271/2145] DATAJDBC-334 - Fixes broken parameter names for
 quoted column names.

When a column has a quoted name it contains characters illegal for parameter names.
Therefore the parameter names now get sanitised.

Original pull request: #120.

Subject: [PATCH 0273/2145] #63 - Add DatabaseClient Coroutines extensions.

This commit introduces Coroutines support for `DatabaseClient`
functional API via Kotlin extensions that provide suspendable
functions prefixed by `await` for `Mono` based APIs.

Extensions for `Flux` will be added when Kotlin/kotlinx.coroutines#254
will be fixed.

It also provides `asType<Foo>()` extensions useful for Reactive API
as well.

Original pull request: #63.

Subject: [PATCH 0275/2145] DATAJDBC-309 - Add Statement Builder API for
 SELECT.

We now provide a Statement Builder API along with a renderer to build statement object graphs and to render these to SQL.

SelectBuilder builder = StatementBuilder.select();

Table employee = SQL.table("employee");
Table department = SQL.table("department");

Column name = employee.column("name").as("emp_name");
Column department_name = employee.column("name").as("department_name");

Select select = builder.select(name, department_name).from(employee).join(department)
		.on(SQL.column("department_id", employee)).equals(SQL.column("id", department))
		.and(SQL.column("tenant", employee)).equals(SQL.column("tenant", department))
		.orderBy(OrderByField.from(name).asc()).build();

String sql = SqlRenderer.render(select);

Subject: [PATCH 0277/2145] DATAJDBC-309 - Polishing.

Javadoc, static factory methods, typos. Refactor SQL rendering from a shared stack-based implementation to independent delegating visitors. Introduce DelegatingVisitor and TypedSubtreeVisitor base classes. Introduce SelectList container. Extract nested renderes to top-level types.

Move SQL renderer to renderer package.

Extend In to multi-expression argument. Introduce helper methods in Table to create multiple columns. Introduce factory method on StatementBuilder to create a new builder given a collection of expressions.

Add support for comparison conditions and LIKE and equal/not equal/less with equals to/greater with equals to conditions.

 Add condition creation methods to Column so Column objects can now create conditions for a fluent DSL as in (.where(left.isGreater(right)).

StatementBuilder.select(left).from(table).where(left.isGreater(right)).build().

Introduce RenderContext and RenderNamingStrategy.

Add since tags. Improve Javadoc.

+ * methods to provide its functionality.
+ * <p/>
+ * <h3>Delegation</h3> Typically, a {@link Visitor} is scoped to a single responsibility. If a {@link Visitor segment}
+ * requires {@link #doEnter(Visitable) processing} that is not directly implemented by the visitor itself, the current
+ * {@link Visitor} can delegate processing to a {@link DelegatingVisitor delegate}. Once a delegation is installed, the
+ * {@link DelegatingVisitor delegate} is used as {@link Visitor} for the current and all subsequent items until it
+ * {@link #doLeave(Visitable) signals} that it is no longer responsible.
+ * <p/>
+ * Nested visitors are required to properly signal once they are no longer responsible for a {@link Visitor segment} to
+ * step back from the delegation. Otherwise, parents are no longer involved in the visitation.
+ * <p/>
+ * Delegation is recursive and limited by the stack size.

Subject: [PATCH 0280/2145] DATAJDBC-335 - Add DSL and renderer for Insert,
 Update, and Delete.

We now provide Statement builders for Insert, Update, and Delete statements.

Table myTable = SQL.table("mytable");

Insert insert = StatementBuilder.insert().into(myTable).values(SQL.bindMarker()).build();

Update update = StatementBuilder.update(table).set(myTable.column("foo").set(SQL.bindMarker())).build();

Delete delete = StatementBuilder.delete().from(table).where(myTable.column("foo").isEqualTo(SQL.literal("bar"))).build();

Original pull request: #121.

Subject: [PATCH 0286/2145] DATAJDBC-326 - Support conversion of
 backreferences.

Ids used as backreferences now get properly converted.

Introduced Identifier to hold information about data that needs to be considered for inserts or updates but is not part of the entity.
Apart from column names and values they also hold information about the desired JdbcType in order to facilitate conversions.
This replaces the Map handed around in the past.

Original pull request: #118.

Subject: [PATCH 0297/2145] DATAJDBC-327 - Add support for conversion to
 JdbcValue and store byte[] as binary.

Some JDBC drivers depend on correct explicit type information in order to pass on parameters to the database.
So far CustomConversion had no way to provide that information.
With this change one can use @WritingConverter that converts to JdbcTypeAware in order to provide that information.

byte[] now also get stored as BINARY.

Original pull request: #123.

-When setting bind parameters with a JDBC driver one may opt to provide a `java.sql.Types` constant value to denote the type of the parameter.
-If for a value this type need to be specified this can be done by using a writing converter as described in the previous section.
-This converter should convert to `JdbcValue` which has a field for the value and one of for the `JDBCType`.
+Value conversion uses `JdbcValue` to enrich values propagated to JDBC operations with a `java.sql.Types` type.

Subject: [PATCH 0300/2145] DATAJDBC-343 - Omit table prefixes for assignment
 columns.

INSERT and UPDATE assignments/column lists no longer include the table prefix for a column as columns as the support is Dialect-specific and we should generally assume columns in these clauses to belong to the table used in the statement.

Subject: [PATCH 0302/2145] #59 - Consider custom conversion in
 MappingR2dbcConverter.

MappingR2dbcConverter now considers custom conversions for inbound and outbound conversion of top-level types (Row to Entity, Entity to OutboundRow) and on property level (e.g. convert an object to String and vice versa).

Original pull request: #70.

+== Mapping Configuration
+
+Unless explicitly configured, an instance of `MappingR2dbcConverter` is created by default when you create a `DatabaseClient`.
+You can create your own instance of the `MappingR2dbcConverter`.
+By creating your own instance, you can register Spring converters to map specific classes to and from the database.
+
+You can configure the `MappingR2dbcConverter` as well as `DatabaseClient` and `ConnectionFactory` by using  Java-based metadata. The following example uses Spring's Java-based configuration:
+
+.@Configuration class to configure R2DBC mapping support
+====
+[source,java]
+----
+@Configuration
+public class MyAppConfig extends AbstractR2dbcConfiguration {
+
+  public ConnectionFactory connectionFactory() {
+    return ConnectionFactories.get("r2dbc:…");
+  }
+
+  // the following are optional
+
+  @Bean
+  @Override
+  public R2dbcCustomConversions r2dbcCustomConversions() {
+
+    List<Converter<?, ?>> converterList = new ArrayList<Converter<?, ?>>();
+    converterList.add(new org.springframework.data.r2dbc.test.PersonReadConverter());
+    converterList.add(new org.springframework.data.r2dbc.test.PersonWriteConverter());
+    return new R2dbcCustomConversions(getStoreConversions(), converterList);
+  }
+}
+----
+====
+
+`AbstractR2dbcConfiguration` requires you to implement a method that defines a `ConnectionFactory`.
+
+You can add additional converters to the converter by overriding the `r2dbcCustomConversions` method.
+
+NOTE: `AbstractR2dbcConfiguration` creates a `DatabaseClient` instance and registers it with the container under the name `databaseClient`.

+=== Overriding Mapping with Explicit Converters
+
+When storing and querying your objects, it is convenient to have a `R2dbcConverter` instance handle the mapping of all Java types to `OutboundRow` instances.
+However, sometimes you may want the `R2dbcConverter` instances do most of the work but let you selectively handle the conversion for a particular type -- perhaps to optimize performance.
+
+To selectively handle the conversion yourself, register one or more one or more `org.springframework.core.convert.converter.Converter` instances with the `R2dbcConverter`.
+
+You can use the `r2dbcCustomConversions` method in `AbstractR2dbcConfiguration` to configure converters. The examples <<mapping-configuration, at the beginning of this chapter>> show how to perform the configuration using Java.
+
+NOTE: Custom top-level entity conversion requires asymmetric types for conversion. Inbound data is extracted from R2DBC's `Row`.
+Outbound data (to be used with `INSERT`/`UPDATE` statements) is represented as `OutboundRow` and later assembled to a statement.
+
+The following example of a Spring Converter implementation converts from a `Row` to a `Person` POJO:
+
+[source,java]
+----
+@ReadingConverter
+ public class PersonReadConverter implements Converter<Row, Person> {
+
+  public Person convert(Row source) {
+    Person p = new Person(source.get("id", String.class),source.get("name", String.class));
+    p.setAge(source.get("age", Integer.class));
+    return p;
+  }
+}
+----
+
+The following example converts from a `Person` to a `OutboundRow`:
+
+[source,java]
+----
+@WritingConverter
+public class PersonWriteConverter implements Converter<Person, OutboundRow> {
+
+  public OutboundRow convert(Person source) {
+    OutboundRow row = new OutboundRow();
+    row.put("_d", source.getId());
+    row.put("name", source.getFirstName());
+    row.put("age", source.getAge());
+    return row;
+  }
+}

Subject: [PATCH 0305/2145] DATAJDBC-336 - URL Cleanup.

This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener).

# HTTP URLs that Could Not Be Fixed
These URLs were unable to be fixed. Please review them to see if they can be manually resolved.

* http://mybatis.org/dtd/mybatis-3-mapper.dtd (301) with 2 occurrences could not be migrated:
   ([https](https://mybatis.org/dtd/mybatis-3-mapper.dtd) result SSLHandshakeException).

# Fixed URLs

## Fixed Success
These URLs were switched to an https URL with a 2xx status. While the status was successful, your review is still recommended.

* http://maven.apache.org/xsd/maven-4.0.0.xsd with 4 occurrences migrated to:
  https://maven.apache.org/xsd/maven-4.0.0.xsd ([https](https://maven.apache.org/xsd/maven-4.0.0.xsd) result 200).
* http://projects.spring.io/spring-data-jdbc with 2 occurrences migrated to:
  https://projects.spring.io/spring-data-jdbc ([https](https://projects.spring.io/spring-data-jdbc) result 301).

# Ignored
These URLs were intentionally ignored.

* http://maven.apache.org/POM/4.0.0 with 8 occurrences
* http://www.w3.org/2001/XMLSchema-instance with 4 occurrences

 |Implementing `EntityInformation`|You can customize the `EntityInformation` abstraction used in the `SimpleJdbcRepository` implementation by creating a subclass of `JdbcRepositoryFactory` and overriding the `getEntityInformation(…)` method.
 You then have to register the custom implementation of `JdbcRepositoryFactory` as a Spring bean.
 Note that this should rarely be necessary. See the link:{javadoc-base}org/springframework/data/jdbc/repository/support/JdbcRepositoryFactory.html[Javadoc] for details.

Subject: [PATCH 0307/2145] #79 - URL Cleanup.

This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener).

# Fixed URLs

## Fixed Success
These URLs were switched to an https URL with a 2xx status. While the status was successful, your review is still recommended.

Subject: [PATCH 0308/2145] DATAJDBC-336 - URL Cleanup.

This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener).

# Fixed URLs

## Fixed Success
These URLs were switched to an https URL with a 2xx status. While the status was successful, your review is still recommended.

Subject: [PATCH 0319/2145] DATAJDBC-340 - Using new SQL generation DSL.

SqlGenerator basically got rewritten using the new SQL rendering API.

The SQL rendering API got some minor improvements in the process.

The whole generation process is now based on paths instead of properties which makes the actual logic of the construction much more obvious.

Subject: [PATCH 0320/2145] DATAJDBC-340 - Polishing.

Encapsulate column caches in Columns type.

Relax RelationalMappingContext to MappingContext with appropriate generics. Remove unused SQL generator source. Cache table and Id column objects. Simplify assertions. Consistently use naming pattern for named parameters.

Migrate http URLs to https.

Original pull request: #147.

Subject: [PATCH 0321/2145] DATAJDBC-357 - Dialect support pagination and array
 support.

We now support Dialect abstractions to consider vendor-specific deviations in SQL query rendering. Dialects support right now:

Feature flags for array support
Limit and Offset handling
The rendering is extended by considering rendering callback hook functions.

Current dialects:

Postgres SQL
SQL Server (2012)
MySQL

Original pull request: #125.

Subject: [PATCH 0322/2145] DATAJDBC-357 - Polishing.

Implemented workaround for MySql not supporting offset without Limit.
Using `SELECT 1` as dummy order by since it is documented to be optimized away.
Renamed tests to match the project standard.

Subject: [PATCH 0334/2145] #75 - Add support for MySQL using jasync-mysql.

We now support MySQL through the jasync-mysql driver that exposes its asynchronous functionality through a R2DBC wrapper implementation.

Jasync uses for now its own exceptions.

Original pull request: #84.

Subject: [PATCH 0336/2145] #75 - Polishing.

Clarified code a little.

Added a warning to `AnonymousBindMarkers`:

 Anonymous bind markers are problematic because the have to appear in generated SQL in the same order they get generated.
 This might cause challenges in the future with complex generate statements.
 For example those containing subselects which limit the freedom of arranging bind markers.

We now attempt to lookup ConnectionFactory from ApplicationContext and fall back to a local
method call if ConnectionFactory is not exposed as bean.

Subject: [PATCH 0341/2145] #100 - Remove Spring JDBC as mandatory dependency.

We now ship our own SqlProvider variant to not require Spring JDBC as mandatory dependency. Spring JDBC can be provided optionally to use SQL-code based exception translation.

Subject: [PATCH 0342/2145] #73 - Introduce PreparedOperation.

We now encapsulate prepared operations from the StatementFactory within PreparedOperation that renders SQL and provides binding values.

StatementFactory supports SELECT/INSERT/UPDATE/DELETE statement creation considering Dialect-specific rendering.
StatementFactory replaces String-based statement methods in ReactiveDataAccessStrategy.

PreparedOperation<Update> operation = accessStrategy.getStatements().update(entity.getTableName(), binder -> {
	binder.bind("name", "updated value");
	binder.filterBy("id", SettableValue.from(42));
});

databaseClient.execute().sql(operation).then();

Original pull request: #82.

We now apply bindings to a BindTarget that can be overridden without the need to implement all Statement methods.

PreparedOperation no longer has a direct dependency on R2DBC Statement.

Original pull request: #82.

From b1c68d901eba5e203351b44fcb307bddc777ca42 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0345/2145] DATAJDBC-359 - Support for arbitrary chains of
 entities with or without Id.

Introduced a `ReadingContext` in the `EntityRowMapper` to avoid passing the `ResultSet` and the `path` all over the place.

Added a dependency test to Spring Data Relational and fixed the test failure by moving the PersistentPropertyPathExtension to core.mapping.

Original pull request: #150.

Subject: [PATCH 0346/2145] DATAJDBC-359 - Polishing.

Deprecate remaining DataAccessStrategy types in jdbc.core and create replacements in jdbc.core.convert. Migrate using code to replacement types.

Simplify warnings and if flows. Add since version to deprecations.

Move MyBatisDataAccessStrategyUnitTests from core to mybatis package.

Original pull request: #150.

Subject: [PATCH 0347/2145] #64 - Add Criteria API.

We now support Criteria creation and mapping to express where conditions with a fluent API.

databaseClient.select().from("legoset")
  .where(Criteria.of("name").like("John%").and("id").lessThanOrEquals(42055));

+The R2DBC support contains a wide range of features:
+
+* Spring configuration support with Java-based `@Configuration` classes  for an R2DBC driver instance.
+* `DatabaseClient` helper class that increases productivity when performing common R2DBC operations with integrated object mapping between rows and POJOs.
+* Exception translation into Spring's portable Data Access Exception hierarchy.
+* Feature-rich Object Mapping integrated with Spring's Conversion Service.
+* Annotation-based mapping metadata that is extensible to support other metadata formats.
+* Automatic implementation of Repository interfaces, including support for custom query methods.
+
+For most tasks, you should use `DatabaseClient` or the Repository support, which both leverage the rich mapping functionality.
+`DatabaseClient` is the place to look for accessing functionality such as ad-hoc CRUD operations.
+
+[[r2dbc.getting-started]]
+== Getting Started
+
+An easy way to bootstrap setting up a working environment is to create a Spring-based project through https://start.spring.io[start.spring.io].
+
+. Add the following to the pom.xml files `dependencies` element:
++
+[source,xml,subs="+attributes"]
+----
+<dependencyManagement>
+  <dependencies>
+    <dependency>
+      <groupId>io.r2dbc</groupId>
+      <artifactId>r2dbc-bom</artifactId>
+      <version>${r2dbc-releasetrain.version}</version>
+      <type>pom</type>
+      <scope>import</scope>
+    </dependency>
+  </dependencies>
+</dependencyManagement>
+
+<dependencies>
+
+  <!-- other dependency elements omitted -->
+
+  <dependency>
+    <groupId>org.springframework.data</groupId>
+    <artifactId>spring-data-r2dbc</artifactId>
+    <version>{version}</version>
+  </dependency>
+
+  <!-- a R2DBC driver -->
+  <dependency>
+    <groupId>io.r2dbc</groupId>
+    <artifactId>r2dbc-h2</artifactId>
+    <version>{r2dbcVersion}</version>
+  </dependency>
+
+</dependencies>
+----
+. Change the version of Spring in the pom.xml to be
++
+[source,xml,subs="+attributes"]
+----
+<spring.framework.version>{springVersion}</spring.framework.version>
+----
+. Add the following location of the Spring Milestone repository for Maven to your `pom.xml` such that it is at the same level of your `<dependencies/>` element:
++
+[source,xml]
+----
+<repositories>
+  <repository>
+    <id>spring-milestone</id>
+    <name>Spring Maven MILESTONE Repository</name>
+    <url>https://repo.spring.io/libs-milestone</url>
+  </repository>
+</repositories>
+----
+
+The repository is also https://repo.spring.io/milestone/org/springframework/data/[browseable here].
+
+You may also want to set the logging level to `DEBUG` to see some additional information. To do so, edit the `application.properties` file to have the following content:
+
+[source]
+----
+logging.level.org.springframework.data.r2dbc=DEBUG
+----
+
+Then you can create a `Person` class to persist:
+
+[source,java]
+----
+package org.spring.r2dbc.example;
+
+public class Person {
+
+  private String id;
+  private String name;
+  private int age;
+
+  public Person(String id, String name, int age) {

+  @Override

+    return "Person [id=" + id + ", name=" + name + ", age=" + age + "]";
+  }
+}
+----
+
+Next, you need to create a table structure in your database:
+
+[source,sql]
+----
+CREATE TABLE person
+  (id VARCHAR(255) PRIMARY KEY,
+   name VARCHAR(255),
+   age INT);
+----
+
+You also need a main application to run:
+
+[source,java]
+----
+package org.spring.r2dbc.example;
+
+public class R2dbcApp {
+
+  private static final Log log = LogFactory.getLog(R2dbcApp.class);
+
+  public static void main(String[] args) throws Exception {
+
+    ConnectionFactory connectionFactory = ConnectionFactories.get("rdbc:h2:mem:///test?options=DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE");
+
+    DatabaseClient client = DatabaseClient.create(connectionFactory);
+
+    client.execute()
+            .sql("CREATE TABLE person" +
+                    "(id VARCHAR(255) PRIMARY KEY," +
+                    "name VARCHAR(255)," +
+                    "age INT)")
+            .fetch()
+            .rowsUpdated()
+            .as(StepVerifier::create)

+            .verifyComplete();
+
+    client.insert()
+            .into(Person.class)
+            .using(new Person("joe", "Joe", 34))
+            .then()
+            .as(StepVerifier::create)
+            .verifyComplete();
+
+    client.select()
+            .from(Person.class)
+            .fetch()
+            .first()
+            .doOnNext(it -> log.info(it))
+            .as(StepVerifier::create)
+            .expectNextCount(1)
+            .verifyComplete();
+  }
+}
+----
+
+When you run the main program, the preceding examples produce output similar to the following:
+
+[source]
+----

+----
+
+Even in this simple example, there are few things to notice:
+
+* You can create an instance of the central helper class in Spring Data R2DBC, <<r2dbc.datbaseclient,`DatabaseClient`>>, by using a standard `io.r2dbc.spi.ConnectionFactory` object.
+* The mapper works against standard POJO objects without the need for any additional metadata (though you can optionally provide that information. See <<mapping-chapter,here>>.).
+* Mapping conventions can use field access. Notice that the `Person` class has only getters.
+* If the constructor argument names match the column names of the stored row, they are used to instantiate the object.
+

+== Examples Repository
+
+There is a https://github.com/spring-projects/spring-data-examples[GitHub repository with several examples] that you can download and play around with to get a feel for how the library works.
+
+[[r2dbc.drivers]]
+== Connecting to a Relational Database with Spring
+
+One of the first tasks when using relational databases and Spring is to create a `io.r2dbc.spi.ConnectionFactory` object using the IoC container. The following example explains Java-based configuration.
+
+[[r2dbc.connectionfactory]]
+=== Registering a `ConnectionFactory` Instance using Java-based Metadata
+
+The following example shows an example of using Java-based bean metadata to register an instance of a `io.r2dbc.spi.ConnectionFactory`:
+
+.Registering a `io.r2dbc.spi.ConnectionFactory` object using Java-based bean metadata
+====
+[source,java]
+----
+@Configuration
+public class ApplicationConfiguration extends AbstractR2dbcConfiguration {
+
+  @Override
+  @Bean
+  public ConnectionFactory connectionFactory() {
+    return …;
+  }
+}
+----
+====
+
+This approach lets you use the standard `io.r2dbc.spi.ConnectionFactory` instance, with the container using Spring's `AbstractR2dbcConfiguration`. As compared to registering a `ConnectionFactory` instance directly, the configuration support has the added advantage of also providing the container with an `ExceptionTranslator` implementation that translates R2DBC exceptions to exceptions in Spring's portable `DataAccessException` hierarchy for data access classes annotated with the `@Repository` annotation. This hierarchy and the use of `@Repository` is described in https://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/data-access.html[Spring's DAO support features].
+
+`AbstractR2dbcConfiguration` registers also `DatabaseClient` that is required for database interaction and for Repository implementation.
+
+[[r2dbc.drivers]]
+=== R2DBC Drivers
+
+Spring Data R2DBC supports drivers by R2DBC's pluggable SPI mechanism. Any driver implementing the R2DBC spec can be used with Spring Data R2DBC.
+R2DBC is a relatively young initiative that gains significance by maturing through adoption.
+As of writing the following 3 drivers are available:
+
+* https://github.com/r2dbc/r2dbc-postgresql[Postgres] (`io.r2dbc:r2dbc-postgresql`)
+* https://github.com/r2dbc/r2dbc-h2[H2] (`io.r2dbc:r2dbc-h2`)
+* https://github.com/r2dbc/r2dbc-mssql[Microsoft SQL Server] (`io.r2dbc:r2dbc-mssql`)
+* https://github.com/jasync-sql/jasync-sql[Microsoft SQL Server] (`com.github.jasync-sql:jasync-r2dbc-mysql`)
+
+Spring Data R2DBC reacts to database specifics by inspecting `ConnectionFactoryMetadata` and selects the appropriate database dialect.
+You can configure an own `Dialect` if the used driver is not yet known to Spring Data R2DBC.

+[[r2dbc.datbaseclient]]
+= Introduction to `DatabaseClient`
+
+Spring Data R2DBC includes a reactive, non-blocking `DatabaseClient` for database interaction. The client has a functional, fluent API with reactive types for declarative composition.
+`DatabaseClient` encapsulates resource handling such as opening and closing connections so your application code can make use of executing SQL queries or calling higher-level functionality such as inserting or selecting data.
+
+NOTE: `DatabaseClient` is a young application component providing a minimal set of convenience methods that is likely to be extended through time.
+
+NOTE: Once configured, `DatabaseClient` is thread-safe and can be reused across multiple instances.
+
+Another central feature of `DatabaseClient` is translation of exceptions thrown by R2DBC drivers into Spring's portable Data Access Exception hierarchy. See "`<<r2dbc.exception>>`" for more information.
+
+The next section contains an example of how to work with the `DatabaseClient` in the context of the Spring container.
+
+[[r2dbc.datbaseclient.create]]
+== Creating `DatabaseClient`
+
+The simplest way to create a `DatabaseClient` is through a static factory method:
+
+[source,java]
+----
+DatabaseClient.create(ConnectionFactory connectionFactory)
+----
+
+The above method creates a `DatabaseClient` with default settings.
+
+You can also use `DatabaseClient.builder()` with further options to customize the client:
+
+* `exceptionTranslator`: Supply a specific `R2dbcExceptionTranslator` to customize how R2DBC exceptions are translated into Spring's portable Data Access Exception hierarchy.  See "`<<r2dbc.exception>>`" for more information.
+* `dataAccessStrategy`: Strategy how SQL queries are generated and how objects are mapped.
+
+Once built, a `DatabaseClient` instance is immutable. However, you can clone it and build a modified copy without affecting the original instance, as the following example shows:
+
+[source,java]
+----
+DatabaseClient client1 = DatabaseClient.builder()
+        .exceptionTranslator(exceptionTranslatorA).build();
+
+DatabaseClient client2 = client1.mutate()
+        .exceptionTranslator(exceptionTranslatorB).build();
+----
+
+== Controlling Database Connections
+
+Spring Data R2DBC obtains a connection to the database through a `ConnectionFactory`.
+A `ConnectionFactory` is part of the R2DBC specification and is a generalized connection factory.
+It lets a container or a framework hide connection pooling and transaction management issues from the application code.
+
+When you use Spring Data R2DBC, you can create a `ConnectionFactory` using your R2DBC driver.
+`ConnectionFactory` implementations can either return the same connection, different connections or provide connection pooling.
+`DatabaseClient` uses `ConnectionFactory` to create and release connections per operation without affinity to a particular connection across multiple operations.
+
+[[r2dbc.exception]]
+= Exception Translation
+
+The Spring framework provides exception translation for a wide variety of database and mapping technologies.
+The Spring support for R2DBC extends this feature by providing implementations of the `R2dbcExceptionTranslator` interface.
+
+`R2dbcExceptionTranslator` is an interface to be implemented by classes that can translate between `R2dbcException` and Spring’s own `org.springframework.dao.DataAccessException`, which is agnostic in regard to data access strategy.
+Implementations can be generic (for example, using SQLState codes) or proprietary (for example, using Postgres error codes) for greater precision.
+
+`R2dbcExceptionSubclassTranslator` is the implementation of `R2dbcExceptionTranslator` that is used by default.
+It considers R2DBC's categorized exception hierarchy to translate these into Spring's consistent exception hierarchy.
+`R2dbcExceptionSubclassTranslator` uses `SqlStateR2dbcExceptionTranslator` as fallback if it is not able to translate an exception.
+
+`SqlErrorCodeR2dbcExceptionTranslator` uses specific vendor codes using Spring JDBC's `SQLErrorCodes`.
+It is more precise than the SQLState implementation.
+The error code translations are based on codes held in a JavaBean type class called `SQLErrorCodes`.
+This class is created and populated by an `SQLErrorCodesFactory`, which (as the name suggests) is a factory for creating SQLErrorCodes based on the contents of a configuration file named `sql-error-codes.xml` from Spring's Data Access module.
+This file is populated with vendor codes and based on the `ConnectionFactoryName` taken from `ConnectionFactoryMetadata`.
+The codes for the actual database you are using are used.
+
+The `SqlErrorCodeR2dbcExceptionTranslator` applies matching rules in the following sequence:
+
+1. Any custom translation implemented by a subclass. Normally, the provided concrete `SqlErrorCodeR2dbcExceptionTranslator` is used, so this rule does not apply. It applies only if you have actually provided a subclass implementation.
+2. Any custom implementation of the `SQLExceptionTranslator` interface that is provided as the `customSqlExceptionTranslator` property of the `SQLErrorCodes` class.
+3. Error code matching is applied.
+4. Use a fallback translator.
+
+NOTE: The `SQLErrorCodesFactory` is used by default to define Error codes and custom exception translations. They are looked up in a file named `sql-error-codes.xml` from the classpath, and the matching `SQLErrorCodes` instance is located based on the database name from the database metadata of the database in use. `SQLErrorCodesFactory` requires Spring JDBC.
+
+You can extend `SqlErrorCodeR2dbcExceptionTranslator`, as the following example shows:
+
+[source,java]
+----
+public class CustomSqlErrorCodeR2dbcExceptionTranslator extends SqlErrorCodeR2dbcExceptionTranslator {
+
+    protected DataAccessException customTranslate(String task, String sql, R2dbcException r2dbcex) {
+        if (sqlex.getErrorCode() == -12345) {
+            return new DeadlockLoserDataAccessException(task, r2dbcex);
+        }
+        return null;
+    }
+}
+----
+
+In the preceding example, the specific error code (`-12345`) is translated, while other errors are left to be translated by the default translator implementation.
+To use this custom translator, you must configure `DatabaseClient` through the builder method `exceptionTranslator`, and you must use this `DatabaseClient` for all of the data access processing where this translator is needed.
+The following example shows how you can use this custom translator:
+
+[source,java]
+----
+ConnectionFactory connectionFactory = …;
+
+CustomSqlErrorCodeR2dbcExceptionTranslator exceptionTranslator = new CustomSqlErrorCodeR2dbcExceptionTranslator();
+
+DatabaseClient client = DatabaseClient.builder()
+                            .connectionFactory(connectionFactory)
+                            .exceptionTranslator(exceptionTranslator)
+                            .build();
+----

+[[r2dbc.datbaseclient.statements]]
+= Running Statements
+
+Running a statement is the basic functionality that is covered by `DatabaseClient`.
+The following example shows what you need to include for a minimal but fully functional class that creates a new table:
+
+[source,java]
+----
+Mono<Void> completion = client.execute()
+        .sql("CREATE TABLE person (id VARCHAR(255) PRIMARY KEY, name VARCHAR(255), age INTEGER);")
+        .then();
+----
+
+`DatabaseClient` is designed for a convenient fluent usage.
+It exposes intermediate, continuation, and terminal methods at each stage of the execution specification.
+The example above uses `then()` to return a completion `Publisher` that completes as soon as the query (or queries, if the SQL query contains multiple statements) completes.
+
+NOTE: `execute().sql(…)` accepts either the SQL query string or a query `Supplier<String>` to defer the actual query creation until execution.
+
+[[r2dbc.datbaseclient.queries]]
+== Running Queries
+
+SQL queries can return values or the number of affected rows.
+`DatabaseClient` can return the number of updated rows or the rows themselves, depending on the issued query.
+
+The following example shows an `UPDATE` statement that returns the number of updated rows:
+
+[source,java]
+----
+Mono<Integer> affectedRows = client.execute()
+        .sql("UPDATE person SET name = 'Joe'")
+        .fetch().rowsUpdated();
+----
+
+Running a `SELECT` query returns a different type of result, in particular tabular results. Tabular data is typically consumes by streaming each `Row`.
+You might have noticed the use of `fetch()` in the previous example.
+`fetch()` is a continuation operator that allows you to specify how much data you want to consume.
+
+[source,java]
+----
+Mono<Map<String, Object>> first = client.execute()
+        .sql("SELECT id, name FROM person")
+        .fetch().first();
+----
+
+Calling `first()` returns the first row from the result and discards remaining rows.
+You can consume data with the following operators:
+
+* `first()` return the first row of the entire result
+* `one()` returns exactly one result and fails if the result contains more rows.
+* `all()` returns all rows of the result
+* `rowsUpdated()` returns the number of affected rows (`INSERT` count, `UPDATE` count)
+
+`DatabaseClient` queries return their results by default as `Map` of column name to value. You can customize type mapping by applying an `as(Class<T>)` operator.
+
+[source,java]
+----
+Flux<Person> all = client.execute()
+        .sql("SELECT id, name FROM mytable")
+        .as(Person.class)
+        .fetch().all();
+----
+
+`as(…)` applies <<mapping-conventions,Convention-based Object Mapping>> and maps the resulting columns to your POJO.
+
+[[r2dbc.datbaseclient.mapping]]
+== Mapping Results
+
+You can customize result extraction beyond `Map` and POJO result extraction by providing an extractor `BiFunction<Row, RowMetadata, T>`.
+The extractor function interacts directly with R2DBC's `Row` and `RowMetadata` objects and can return arbitrary values (singular values, collections/maps, objects).
+
+The following example extracts the `id` column and emits its value:
+
+[source,java]
+----
+Flux<String> names= client.execute()
+        .sql("SELECT name FROM person")
+        .map((row, rowMetadata) -> row.get("id", String.class))
+        .all();
+----
+
+[[r2dbc.datbaseclient.mapping.null]]
+.What about `null`?
+****
+Relational database results may contain `null` values.
+Reactive Streams forbids emission of `null` values which requires a proper `null` handling in the extractor function.
+While you can obtain `null` values from a `Row`, you must not emit a `null` value.
+You must wrap any `null` values in an object (e.g. `Optional` for singular values) to make sure a `null` value is never returned directly by your extractor function.
+****
+
+[[r2dbc.datbaseclient.binding]]
+== Binding Values to Queries
+
+A typical application requires parameterized SQL statements to select or update rows according to some input.
+These are typically `SELECT` statements  constrained by a `WHERE` clause or `INSERT`/`UPDATE` statements accepting input parameters.
+Parameterized statements bear the risk of SQL injection if parameters are not escaped properly.
+`DatabaseClient` leverages R2DBC's Bind API to eliminate the risk of SQL injection for query parameters.
+You can provide a parameterized SQL statement with the `sql(…)` operator and bind parameters to the actual `Statement`.
+Your R2DBC driver then executes the statement using prepared statements and parameter substitution.
+
+Parameter binding supports various binding strategies:
+
+* By Index using zero-based parameter indexes.
+* By Name using the placeholder name.
+
+The following example shows parameter binding for a query:
+
+[source,java]
+----
+db.execute()
+    .sql("INSERT INTO person (id, name, age) VALUES(:id, :name, :age)")
+    .bind("id", "joe")
+    .bind("name", "Joe")
+    .bind("age", 34);
+----
+
+.R2DBC Native Bind Markers
+****
+R2DBC uses database-native bind markers that depend on the actual database vendor.
+As an example, Postgres uses indexed markers such as `$1`, `$2`, `$n`.
+Another example is SQL Server that uses named bind markers prefixed with `@` (at).
+
+This is different from JDBC which requires `?` (question mark) as bind markers.
+In JDBC, the actual drivers translate question mark bind markers to database-native markers as part of their statement execution.
+
+Spring Data R2DBC allows you to use native bind markers or named bind markers with the `:name` syntax.
+
+Named parameter support leverages ``Dialect``s  to expand named parameters to native bind markers at the time of query execution which gives you a certain degree of query portability across various database vendors.
+****
+
+The query-preprocessor unrolls named `Collection` parameters into a series of bind markers to remove the need of dynamic query creation based on the number of arguments.
+Nested object arrays are expanded to allow usage of e.g. select lists.
+
+Consider the following query:
+
+[source,sql]
+----
+SELECT id, name, state FROM table WHERE (name, age) IN (('John', 35), ('Ann', 50))
+----
+
+This query can be parametrized and executed as:
+
+[source,java]
+----
+List<Object[]> tuples = new ArrayList<>();
+tuples.add(new Object[] {"John", 35});
+tuples.add(new Object[] {"Ann",  50});
+
+db.execute()
+    .sql("SELECT id, name, state FROM table WHERE (name, age) IN (:tuples)")
+    .bind("tuples", tuples);
+----
+
+NOTE: Usage of select lists is vendor-dependent.
+
+A simpler variant using `IN` predicates:
+
+[source,java]
+----
+db.execute()
+    .sql("SELECT id, name, state FROM table WHERE age IN (:ages)")
+    .bind("ages", Arrays.asList(35, 50));

+[[r2dbc.datbaseclient.transactions]]
+== Transactions
+
+A common pattern when using relational databases is grouping multiple queries within a unit of work that is guarded by a transaction.
+Relational databases typically associate a transaction with a single transport connection.
+Using different connections hence results in utilizing different transactions.
+Spring Data R2DBC includes a transactional `DatabaseClient` implementation with `TransactionalDatabaseClient` that allows you to group multiple statements within the same transaction.
+`TransactionalDatabaseClient` is a extension of `DatabaseClient` that exposes the same functionality as `DatabaseClient` and adds transaction-management methods.
+
+You can run multiple statements within a transaction using the `inTransaction(Function)` closure:
+
+[source,java]
+----
+TransactionalDatabaseClient databaseClient = TransactionalDatabaseClient.create(connectionFactory);
+
+Flux<Void> completion = databaseClient.inTransaction(db -> {
+
+    return db.execute().sql("INSERT INTO person (id, name, age) VALUES(:id, :name, :age)")

-  public String toString() {
-    return "Person [id=" + id + ", name=" + name + ", age=" + age + "]";
-  }
-}
-----
-
-Next, you need to create a table structure in your database:
-
-[source,sql]
-----
-CREATE TABLE person
-  (id VARCHAR(255) PRIMARY KEY,
-   name VARCHAR(255),
-   age INT);
-----
-
-You also need a main application to run:
-
-[source,java]
-----
-package org.spring.r2dbc.example;
-
-public class R2dbcApp {
-
-  private static final Log log = LogFactory.getLog(R2dbcApp.class);
-
-  public static void main(String[] args) throws Exception {
-
-    ConnectionFactory connectionFactory = new H2ConnectionFactory(H2ConnectionConfiguration.builder()
-                                .url("/service/mem:test;DB_CLOSE_DELAY=10")
-                                .build());
-
-    DatabaseClient client = DatabaseClient.create(connectionFactory);
-
-    client.execute()
-            .sql("CREATE TABLE person" +
-                    "(id VARCHAR(255) PRIMARY KEY," +
-                    "name VARCHAR(255)," +
-                    "age INT)")
-            .fetch()
-            .rowsUpdated()
-            .as(StepVerifier::create)
-            .expectNextCount(1)
-            .verifyComplete();
-
-    client.insert()
-            .into(Person.class)
-            .using(new Person("joe", "Joe", 34))
-            .then()
-            .as(StepVerifier::create)
-            .verifyComplete();
-
-    client.select()
-            .from(Person.class)
-            .fetch()
-            .first()
-            .doOnNext(it -> log.info(it))
-            .as(StepVerifier::create)
-            .expectNextCount(1)
-            .verifyComplete();
-  }
-}
-----
-
-When you run the main program, the preceding examples produce output similar to the following:
-
-[source]
-----

-----
-
-Even in this simple example, there are few things to notice:
-
-* You can create an instance of the central helper class in Spring Data R2DBC, <<r2dbc.datbaseclient,`DatabaseClient`>>, by using a standard `io.r2dbc.spi.ConnectionFactory` object.
-* The mapper works against standard POJO objects without the need for any additional metadata (though you can optionally provide that information. See <<mapping-chapter,here>>.).
-* Mapping conventions can use field access. Notice that the `Person` class has only getters.
-* If the constructor argument names match the column names of the stored row, they are used to instantiate the object.
-
-[[r2dbc.examples-repo]]
-== Examples Repository
-
-There is a https://github.com/spring-projects/spring-data-examples[GitHub repository with several examples] that you can download and play around with to get a feel for how the library works.
-
-[[r2dbc.drivers]]
-== Connecting to a Relational Database with Spring
-
-One of the first tasks when using relational databases and Spring is to create a `io.r2dbc.spi.ConnectionFactory` object using the IoC container. The following example explains Java-based configuration.
-
-[[r2dbc.connectionfactory]]
-=== Registering a `ConnectionFactory` Instance using Java-based Metadata
-
-The following example shows an example of using Java-based bean metadata to register an instance of a `io.r2dbc.spi.ConnectionFactory`:
-
-.Registering a `io.r2dbc.spi.ConnectionFactory` object using Java-based bean metadata
-====
-[source,java]
-----
-@Configuration
-public class ApplicationConfiguration extends AbstractR2dbcConfiguration {
-
-  @Override
-  @Bean
-  public ConnectionFactory connectionFactory() {
-    return …;
-  }
-}
-----
-====
-
-This approach lets you use the standard `io.r2dbc.spi.ConnectionFactory` instance, with the container using Spring's `AbstractR2dbcConfiguration`. As compared to registering a `ConnectionFactory` instance directly, the configuration support has the added advantage of also providing the container with an `ExceptionTranslator` implementation that translates R2DBC exceptions to exceptions in Spring's portable `DataAccessException` hierarchy for data access classes annotated with the `@Repository` annotation. This hierarchy and the use of `@Repository` is described in https://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/data-access.html[Spring's DAO support features].
-
-`AbstractR2dbcConfiguration` registers also `DatabaseClient` that is required for database interaction and for Repository implementation.
-
-[[r2dbc.drivers]]
-=== R2DBC Drivers
-
-Spring Data R2DBC supports drivers by R2DBC's pluggable SPI mechanism. Any driver implementing the R2DBC spec can be used with Spring Data R2DBC.
-R2DBC is a relatively young initiative that gains significance by maturing through adoption.
-As of writing the following 3 drivers are available:
-
-* https://github.com/r2dbc/r2dbc-postgresql[Postgres] (`io.r2dbc:r2dbc-postgresql`)
-* https://github.com/r2dbc/r2dbc-h2[H2] (`io.r2dbc:r2dbc-h2`)
-* https://github.com/r2dbc/r2dbc-mssql[Microsoft SQL Server] (`io.r2dbc:r2dbc-mssql`)
-
-Spring Data R2DBC reacts to database specifics by inspecting `ConnectionFactoryMetadata` and selects the appropriate database dialect.
-You can configure an own `Dialect` if the used driver is not yet known to Spring Data R2DBC.
-
-[[r2dbc.datbaseclient]]
-== Introduction to `DatabaseClient`
-
-Spring Data R2DBC includes a reactive, non-blocking `DatabaseClient` for database interaction. The client has a functional, fluent API with reactive types for declarative composition.
-`DatabaseClient` encapsulates resource handling such as opening and closing connections so your application code can make use of executing SQL queries or calling higher-level functionality such as inserting or selecting data.
-
-NOTE: `DatabaseClient` is a young application component providing a minimal set of convenience methods that is likely to be extended through time.
-
-NOTE: Once configured, `DatabaseClient` is thread-safe and can be reused across multiple instances.
-
-Another central feature of `DatabaseClient` is translation of exceptions thrown by R2DBC drivers into Spring's portable Data Access Exception hierarchy. See "`<<r2dbc.exception>>`" for more information.
-
-The next section contains an example of how to work with the `DatabaseClient` in the context of the Spring container.
-
-[[r2dbc.datbaseclient.create]]
-=== Creating `DatabaseClient`
-
-The simplest way to create a `DatabaseClient` is through a static factory method:
-
-[source,java]
-----
-DatabaseClient.create(ConnectionFactory connectionFactory)
-----
-
-The above method creates a `DatabaseClient` with default settings.
-
-You can also use `DatabaseClient.builder()` with further options to customize the client:
-
-* `exceptionTranslator`: Supply a specific `R2dbcExceptionTranslator` to customize how R2DBC exceptions are translated into Spring's portable Data Access Exception hierarchy.  See "`<<r2dbc.exception>>`" for more information.
-* `dataAccessStrategy`: Strategy how SQL queries are generated and how objects are mapped.
-
-Once built, a `DatabaseClient` instance is immutable. However, you can clone it and build a modified copy without affecting the original instance, as the following example shows:
-
-[source,java]
-----
-DatabaseClient client1 = DatabaseClient.builder()
-        .exceptionTranslator(exceptionTranslatorA).build();
-
-DatabaseClient client2 = client1.mutate()
-        .exceptionTranslator(exceptionTranslatorB).build();
-----
-
-=== Controlling Database Connections
-
-Spring Data R2DBC obtains a connection to the database through a `ConnectionFactory`.
-A `ConnectionFactory` is part of the R2DBC specification and is a generalized connection factory.
-It lets a container or a framework hide connection pooling and transaction management issues from the application code.
-
-When you use Spring Data R2DBC, you can create a `ConnectionFactory` using your R2DBC driver.
-`ConnectionFactory` implementations can either return the same connection, different connections or provide connection pooling.
-`DatabaseClient` uses `ConnectionFactory` to create and release connections per operation without affinity to a particular connection across multiple operations.
-
-[[r2dbc.exception]]
-== Exception Translation
-
-The Spring framework provides exception translation for a wide variety of database and mapping technologies.
-This has traditionally been for JDBC and JPA. The Spring support for R2DBC extends this feature by providing implementations of the `R2dbcExceptionTranslator` interface.
-
-`R2dbcExceptionTranslator` is an interface to be implemented by classes that can translate between `R2dbcException` and Spring’s own `org.springframework.dao.DataAccessException`, which is agnostic in regard to data access strategy.
-Implementations can be generic (for example, using SQLState codes) or proprietary (for example, using Postgres error codes) for greater precision.
-
-`SqlErrorCodeR2dbcExceptionTranslator` is the implementation of `R2dbcExceptionTranslator` that is used by default.
-This implementation uses specific vendor codes.
-It is more precise than the SQLState implementation.
-The error code translations are based on codes held in a JavaBean type class called `SQLErrorCodes`.
-This class is created and populated by an `SQLErrorCodesFactory`, which (as the name suggests) is a factory for creating SQLErrorCodes based on the contents of a configuration file named `sql-error-codes.xml` from Spring's Data Access module.
-This file is populated with vendor codes and based on the `ConnectionFactoryName` taken from `ConnectionFactoryMetadata`.
-The codes for the actual database you are using are used.
-
-The `SqlErrorCodeR2dbcExceptionTranslator` applies matching rules in the following sequence:
-
-1. Any custom translation implemented by a subclass. Normally, the provided concrete `SqlErrorCodeR2dbcExceptionTranslator` is used, so this rule does not apply. It applies only if you have actually provided a subclass implementation.
-2. Any custom implementation of the `SQLExceptionTranslator` interface that is provided as the `customSqlExceptionTranslator` property of the `SQLErrorCodes` class.
-3. Error code matching is applied.
-4. Use a fallback translator.
-
-
-NOTE: The `SQLErrorCodesFactory` is used by default to define Error codes and custom exception translations. They are looked up in a file named `sql-error-codes.xml` from the classpath, and the matching `SQLErrorCodes` instance is located based on the database name from the database metadata of the database in use. `SQLErrorCodesFactory` is as of now part of Spring JDBC. Spring Data R2DBC reuses existing translation configurations.
-
-You can extend `SqlErrorCodeR2dbcExceptionTranslator`, as the following example shows:
-
-[source,java]
-----
-public class CustomSqlErrorCodeR2dbcExceptionTranslator extends SqlErrorCodeR2dbcExceptionTranslator {
-
-    protected DataAccessException customTranslate(String task, String sql, R2dbcException r2dbcex) {
-        if (sqlex.getErrorCode() == -12345) {
-            return new DeadlockLoserDataAccessException(task, r2dbcex);
-        }
-        return null;
-    }
-}
-----
-
-In the preceding example, the specific error code (`-12345`) is translated, while other errors are left to be translated by the default translator implementation.
-To use this custom translator, you must configure `DatabaseClient` through the builder method `exceptionTranslator`, and you must use this `DatabaseClient` for all of the data access processing where this translator is needed.
-The following example shows how you can use this custom translator:
-
-[source,java]
-----
-ConnectionFactory connectionFactory = …;
-
-CustomSqlErrorCodeR2dbcExceptionTranslator exceptionTranslator = new CustomSqlErrorCodeR2dbcExceptionTranslator();
-
-DatabaseClient client = DatabaseClient.builder()
-                            .connectionFactory(connectionFactory)
-                            .exceptionTranslator(exceptionTranslator)
-                            .build();
-----
-
-[[r2dbc.datbaseclient.statements]]
-=== Running Statements
-
-Running a statement is the basic functionality that is covered by `DatabaseClient`.
-The following example shows what you need to include for a minimal but fully functional class that creates a new table:
-
-[source,java]
-----
-Mono<Void> completion = client.execute()
-        .sql("CREATE TABLE person (id VARCHAR(255) PRIMARY KEY, name VARCHAR(255), age INTEGER);")
-        .then();
-----
-
-`DatabaseClient` is designed for a convenient fluent usage.
-It exposes intermediate, continuation, and terminal methods at each stage of the execution specification.
-The example above uses `then()` to return a completion `Publisher` that completes as soon as the query (or queries, if the SQL query contains multiple statements) completes.
-
-NOTE: `execute().sql(…)` accepts either the SQL query string or a query `Supplier<String>` to defer the actual query creation until execution.
-
-[[r2dbc.datbaseclient.queries]]
-=== Running Queries
-
-SQL queries can return values or the number of affected rows.
-`DatabaseClient` can return the number of updated rows or the rows themselves, depending on the issued query.
-
-The following example shows an `UPDATE` statement that returns the number of updated rows:
-
-[source,java]
-----
-Mono<Integer> affectedRows = client.execute()
-        .sql("UPDATE person SET name = 'Joe'")
-        .fetch().rowsUpdated();
-----
-
-Running a `SELECT` query returns a different type of result, in particular tabular results. Tabular data is typically consumes by streaming each `Row`.
-You might have noticed the use of `fetch()` in the previous example.
-`fetch()` is a continuation operator that allows you to specify how much data you want to consume.
-
-[source,java]
-----
-Mono<Map<String, Object>> first = client.execute()
-        .sql("SELECT id, name FROM person")
-        .fetch().first();
-----
-
-Calling `first()` returns the first row from the result and discards remaining rows.
-You can consume data with the following operators:
-
-* `first()` return the first row of the entire result
-* `one()` returns exactly one result and fails if the result contains more rows.
-* `all()` returns all rows of the result
-* `rowsUpdated()` returns the number of affected rows (`INSERT` count, `UPDATE` count)
-
-`DatabaseClient` queries return their results by default as `Map` of column name to value. You can customize type mapping by applying an `as(Class<T>)` operator.
-
-[source,java]
-----
-Flux<Person> all = client.execute()
-        .sql("SELECT id, name FROM mytable")
-        .as(Person.class)
-        .fetch().all();
-----
-
-`as(…)` applies <<mapping-conventions,Convention-based Object Mapping>> and maps the resulting columns to your POJO.
-
-[[r2dbc.datbaseclient.mapping]]
-=== Mapping Results
-
-You can customize result extraction beyond `Map` and POJO result extraction by providing an extractor `BiFunction<Row, RowMetadata, T>`.
-The extractor function interacts directly with R2DBC's `Row` and `RowMetadata` objects and can return arbitrary values (singular values, collections/maps, objects).
-
-The following example extracts the `id` column and emits its value:
-
-[source,java]
-----
-Flux<String> names= client.execute()
-        .sql("SELECT name FROM person")
-        .map((row, rowMetadata) -> row.get("id", String.class))
-        .all();
-----
-
-[[r2dbc.datbaseclient.mapping.null]]
-.What about `null`?
-****
-Relational database results may contain `null` values.
-Reactive Streams forbids emission of `null` values which requires a proper `null` handling in the extractor function.
-While you can obtain `null` values from a `Row`, you must not emit a `null` value.
-You must wrap any `null` values in an object (e.g. `Optional` for singular values) to make sure a `null` value is never returned directly by your extractor function.
-****
-
-[[r2dbc.datbaseclient.binding]]
-=== Binding Values to Queries
-
-A typical application requires parameterized SQL statements to select or update rows according to some input.
-These are typically `SELECT` statements  constrained by a `WHERE` clause or `INSERT`/`UPDATE` statements accepting input parameters.
-Parameterized statements bear the risk of SQL injection if parameters are not escaped properly.
-`DatabaseClient` leverages R2DBC's Bind API to eliminate the risk of SQL injection for query parameters.
-You can provide a parameterized SQL statement with the `sql(…)` operator and bind parameters to the actual `Statement`.
-Your R2DBC driver then executes the statement using prepared statements and parameter substitution.
-
-Parameter binding supports various binding strategies:
-
-* By Index using zero-based parameter indexes.
-* By Name using the placeholder name.
-
-The following example shows parameter binding for a query:
-
-[source,java]
-----
-db.execute()
-    .sql("INSERT INTO person (id, name, age) VALUES(:id, :name, :age)")
-    .bind("id", "joe")
-    .bind("name", "Joe")
-    .bind("age", 34);
-----
-
-.R2DBC Native Bind Markers
-****
-R2DBC uses database-native bind markers that depend on the actual database vendor.
-As an example, Postgres uses indexed markers such as `$1`, `$2`, `$n`.
-Another example is SQL Server that uses named bind markers prefixed with `@` (at).
-
-This is different from JDBC which requires `?` (question mark) as bind markers.
-In JDBC, the actual drivers translate question mark bind markers to database-native markers as part of their statement execution.
-
-Spring Data R2DBC allows you to use native bind markers or named bind markers with the `:name` syntax.
-
-Named parameter support leverages ``Dialect``s  to expand named parameters to native bind markers at the time of query execution which gives you a certain degree of query portability across various database vendors.
-****
-
-The query-preprocessor unrolls named `Collection` parameters into a series of bind markers to remove the need of dynamic query creation based on the number of arguments.
-Nested object arrays are expanded to allow usage of e.g. select lists.
-
-Consider the following query:
-
-[source,sql]
-----
-SELECT id, name, state FROM table WHERE (name, age) IN (('John', 35), ('Ann', 50))
-----
-
-This query can be parametrized and executed as:
-
-[source,java]
-----
-List<Object[]> tuples = new ArrayList<>();
-tuples.add(new Object[] {"John", 35});
-tuples.add(new Object[] {"Ann",  50});
-
-db.execute()
-    .sql("SELECT id, name, state FROM table WHERE (name, age) IN (:tuples)")
-    .bind("tuples", tuples);
-----
-
-NOTE: Usage of select lists is vendor-dependent.
-
-A simpler variant using `IN` predicates:
-
-[source,java]
-----
-db.execute()
-    .sql("SELECT id, name, state FROM table WHERE age IN (:ages)")
-    .bind("ages", Arrays.asList(35, 50));
-----
-
-[[r2dbc.datbaseclient.transactions]]
-=== Transactions
-
-A common pattern when using relational databases is grouping multiple queries within a unit of work that is guarded by a transaction.
-Relational databases typically associate a transaction with a single transport connection.
-Using different connections hence results in utilizing different transactions.
-Spring Data R2DBC includes a transactional `DatabaseClient` implementation with `TransactionalDatabaseClient` that allows you to group multiple statements within the same transaction.
-`TransactionalDatabaseClient` is a extension of `DatabaseClient` that exposes the same functionality as `DatabaseClient` and adds transaction-management methods.
-
-You can run multiple statements within a transaction using the `inTransaction(Function)` closure:
-
-[source,java]
-----
-TransactionalDatabaseClient databaseClient = TransactionalDatabaseClient.create(connectionFactory);
-
-Flux<Void> completion = databaseClient.inTransaction(db -> {
-
-    return db.execute().sql("INSERT INTO person (id, name, age) VALUES(:id, :name, :age)")
-            .bind("id", "joe")
-            .bind("name", "Joe")
-            .bind("age", 34)
-            .fetch().rowsUpdated()
-            .then(db.execute().sql("INSERT INTO contacts (id, name) VALUES(:id, :name)")
-                    .bind("id", "joe")
-                    .bind("name", "Joe")
-                    .fetch().rowsUpdated())
-            .then();
-});

+= Fluent Data Access API
+
+You have already seen ``DatabaseClient``s SQL API that offers you maximum flexibility to execute any type of SQL.
+`DatabaseClient` provides a more narrow interface for typical ad-hoc use-cases such as querying, inserting, updating, and deleting data.
+
+The entry points (`insert()`, `select()`, `update()`, and others) follow a natural naming schema based on the operation to be run. Moving on from the entry point, the API is designed to offer only context-dependent methods that lead to a terminating method that creates and runs a SQL statement. Spring Data R2DBC uses a `Dialect` abstraction to determine bind markers, pagination support and  data types natively supported by the underlying driver.
+
+Let's take a look at a simple query:
+
+====
+[source,java]
+----
+Flux<Person> people = databaseClient.select()
+        .from(Person.class)                       <1>
+        .fetch()
+        .all();                                   <2>
+----
+<1> Using `Person` with the `from(…)` method sets the `FROM` table based on mapping metadata. It also maps tabular results on `Person` result objects.
+<2> Fetching `all()` rows returns a `Flux<Person>` without limiting results.
+====
+
+The following example declares a more complex query that specifies the table name by name, a `WHERE` condition and `ORDER BY` clause:
+
+====
+[source,java]
+----
+Mono<Person> first = databaseClient.select()
+        .from("legoset")                                  <1>
+        .matching(where("firstname").is("John")           <2>
+                .and("lastname").in("Doe", "White"))
+        .orderBy(desc("id"))                              <3>
+        .as(Person.class)
+        .fetch()
+        .one();                                           <4>
+----
+<1> Selecting from a table by name returns row results as `Map<String, Object>` with case-insensitive column name matching.
+<2> The issued query declares a `WHERE` condition on `firstname` and `lastname` columns to filter results.
+<3> Results can be ordered by individual column names resulting in an `ORDER BY` clause.
+<4> Selecting the one result fetches just a single row. This way of consuming rows expects the query to return exactly a single result. `Mono` emits a `IncorrectResultSizeDataAccessException` if the query yields more than a single result.
+====
+
+You can consume Query results in three ways:
+
+* Through object mapping (e.g. `as(Class<T>)`) using Spring Data's mapping-metadata.
+* As `Map<String, Object>` where column names are mapped to their value. Column names are looked up case-insensitive.
+* By supplying a mapping `BiFunction` for direct access to R2DBC `Row` and `RowMetadata`
+
+You can switch between retrieving a single entity and retrieving multiple entities as through the terminating methods:
+
+* `first()`: Consume only the first row returning a `Mono`. The returned `Mono` completes without emitting an object if the query returns no results.
+* `one()`: Consume exactly one row returning a `Mono`. The returned `Mono` completes without emitting an object if the query returns no results. If the query returns more than row then `Mono` completes exceptionally emitting `IncorrectResultSizeDataAccessException`.
+* `all()`: Consume all returned rows returning a `Flux`.
+* `rowsUpdated`: Consume the number of affected rows. Typically used with `INSERT`/`UPDATE`/`DELETE`  statements.
+
+[[r2dbc.datbaseclient.fluent-api.select]]
+== Selecting Data
+
+Use the `select()` entry point to express your `SELECT` queries.
+The resulting `SELECT` queries support the commonly used clauses `WHERE`, `ORDER BY` and support pagination.
+The fluent API style allows you to chain together multiple methods while having easy-to-understand code.
+To improve readability, use static imports that allow you avoid using the 'new' keyword for creating `Criteria` instances.
+
+[r2dbc.datbaseclient.fluent-api.criteria]]
+==== Methods for the Criteria Class
+
+The `Criteria` class provides the following methods, all of which correspond to SQL operators:
+
+* `Criteria` *and* `(String column)` Adds a chained `Criteria` with the specified `property` to the current `Criteria` and returns the newly created one.
+* `Criteria` *or* `(String column)` Adds a chained `Criteria` with the specified `property` to the current `Criteria` and returns the newly created one.
+* `Criteria` *greaterThan* `(Object o)` Creates a criterion using the `>` operator.
+* `Criteria` *greaterThanOrEquals* `(Object o)` Creates a criterion using the `>=` operator.
+* `Criteria` *in* `(Object... o)` Creates a criterion using the `IN` operator for a varargs argument.
+* `Criteria` *in* `(Collection<?> collection)` Creates a criterion using the `IN` operator using a collection.
+* `Criteria` *is* `(Object o)` Creates a criterion using column matching (`property = value`).
+* `Criteria` *isNull* `()` Creates a criterion using the `IS NULL` operator.
+* `Criteria` *isNotNull* `()` Creates a criterion using the `IS NOT NULL` operator.
+* `Criteria` *lessThan* `(Object o)` Creates a criterion using the `<` operator.
+* `Criteria` *lessThanOrEquals* `(Object o)` Creates a criterion using the `<=` operator.
+* `Criteria` *like* `(Object o)` Creates a criterion using the `LIKE` operator without escape character processing.
+* `Criteria` *not* `(Object o)` Creates a criterion using the `!=` operator.
+* `Criteria` *notIn* `(Object... o)` Creates a criterion using the `NOT IN` operator for a varargs argument.
+* `Criteria` *notIn* `(Collection<?> collection)` Creates a criterion using the `NOT IN` operator using a collection.
+
+You can use `Criteria` with `SELECT`, `UPDATE`, and `DELETE` queries.
+
+[r2dbc.datbaseclient.fluent-api.select.methods]]
+==== Methods for SELECT operations
+
+The `select()` entry point exposes some additional methods that provide options for the query:
+
+* *from* `(Class<T>)` used to specify the source table using a mapped object. Returns results by default as `T`.
+* *from* `(String)` used to specify the source table name. Returns results by default as `Map<String, Object>`.
+* *as* `(Class<T>)` used to map results to `T`.
+* *map* `(BiFunction<Row, RowMetadata, T>)` used to supply a mapping function to extract results.
+* *project* `(String... columns)` used to specify which columns to return.
+* *matching* `(Criteria)` used to declare a `WHERE` condition to filter results.
+* *orderBy* `(Order)` used to declare a `ORDER BY` clause to sort results.
+* *page* `(Page pageable)` used to retrieve a particular page within the result. Limits the size of the returned results and reads from a  offset.
+* *fetch* `()` transition call declaration to the fetch stage to declare result consumption multiplicity.
+
+[[r2dbc.datbaseclient.fluent-api.insert]]
+== Inserting Data
+
+Use the `insert()` entry point to insert data. Similar to `select()`, `insert()` allows free-form and mapped object inserts.
+
+Take a look at a simple typed insert operation:
+
+====
+[source,java]
+----
+Mono<Void> insert = databaseClient.insert()
+        .into(Person.class)                       <1>
+        .using(new Person(…))                     <2>
+        .then();                                  <3>
+----
+<1> Using `Person` with the `into(…)` method sets the `INTO` table based on mapping metadata. It also prepares the insert statement to accept `Person` objects for inserting.
+<2> Provide a scalar `Person` object. Alternatively, you can supply a `Publisher` to execute a stream of `INSERT` statements. This method extracts all non-``null`` values and inserts these.
+<3> Use `then()` to just insert an object without consuming further details. Modifying statements allow consumption of the number of affected rows or tabular results for consuming generated keys.
+====
+
+Inserts also support untyped operations:
+
+====
+[source,java]
+----
+Mono<Void> insert = databaseClient.insert()
+        .into("person")                           <1>
+        .value("firstname", "John")               <2>
+        .nullValue("lastname")                    <3>
+        .then();                                  <4>
+----
+<1> Start an insert into the `person` table.
+<2> Provide a non-null value for  `firstname`.
+<3> Set `lastname` to `null`.
+<3> Use `then()` to just insert an object without consuming further details. Modifying statements allow consumption of the number of affected rows or tabular results for consuming generated keys.
+====
+
+[r2dbc.datbaseclient.fluent-api.insert.methods]]
+==== Methods for INSERT operations
+
+The `insert()` entry point exposes some additional methods that provide options for the operation:
+
+* *into* `(Class<T>)` used to specify the target table using a mapped object. Returns results by default as `T`.
+* *into* `(String)` used to specify the target table name. Returns results by default as `Map<String, Object>`.
+* *using* `(T)` used to specify the object to insert.
+* *using* `(Publisher<T>)` used to accept a stream of objects to insert.
+* *table* `(String)` used to override the target table name.
+* *value* `(String, Object)` used to provide a column value to insert.
+* *nullValue* `(String)` used to provide a null value to insert.
+* *map* `(BiFunction<Row, RowMetadata, T>)` used to supply a mapping function to extract results.
+* *then* `()` execute `INSERT` without consuming any results.
+* *fetch* `()` transition call declaration to the fetch stage to declare result consumption multiplicity.
+
+[[r2dbc.datbaseclient.fluent-api.update]]
+== Updating Data
+
+Use the `update()` entry point to update rows.
+Updating data starts with a specification of the table to update accepting `Update` specifying assignments. It also accepts `Criteria` to create a `WHERE` clause.
+
+Take a look at a simple typed update operation:
+
+====
+[source,java]
+----
+Person modified = …
+
+Mono<Void> update = databaseClient.update()
+        .table(Person.class)                              <1>
+        .using(modified)                                  <2>
+        .then();                                          <3>
+----
+<1> Using `Person` with the `table(…)` method sets the table to update based on mapping metadata.
+<2> Provide a scalar `Person` object value. `using(…)` accepts the modified object and derives primary keys and updates all column values.
+<3> Use `then()` to just update rows an object without consuming further details. Modifying statements allow also consumption of the number of affected rows.
+====
+
+Update also support untyped operations:
+
+====
+[source,java]
+----
+Mono<Void> update = databaseClient.update()
+        .table("person")                                  <1>
+        .using(Update.update("firstname", "Jane"))        <2>
+        .matching(where("firstname").is("John"))          <3>
+        .then();                                          <4>
+----
+<1> Update table `person`.
+<2> Provide a `Update` definition, which columns to update.
+<3> The issued query declares a `WHERE` condition on `firstname` columns to filter rows to update.
+<4> Use `then()` to just update rows an object without consuming further details. Modifying statements allow also consumption of the number of affected rows.
+====
+
+[r2dbc.datbaseclient.fluent-api.delete.methods]]
+==== Methods for DELETE operations
+
+The `delete()` entry point exposes some additional methods that provide options for the operation:
+
+* *table* `(Class<T>)` used to specify the target table using a mapped object. Returns results by default as `T`.
+* *table* `(String)` used to specify the target table name. Returns results by default as `Map<String, Object>`.
+* *using* `(T)` used to specify the object to update. Derives criteria itself.
+* *using* `(Update)` used to specify the update definition.
+* *matching* `(Criteria)` used to declare a `WHERE` condition to rows to update.
+* *then* `()` execute `UPDATE` without consuming any results.
+* *fetch* `()` transition call declaration to the fetch stage to fetch the number of updated rows.
+
+[[r2dbc.datbaseclient.fluent-api.delete]]
+== Deleting Data
+
+Use the `delete()` entry point to delete rows.
+Removing data starts with a specification of the table to delete from and optionally accepts a `Criteria` to create a `WHERE` clause.
+
+Take a look at a simple insert operation:
+
+====
+[source,java]
+----
+Mono<Void> delete = databaseClient.delete()
+        .from(Person.class)                               <1>
+        .matching(where("firstname").is("John")           <2>
+                .and("lastname").in("Doe", "White"))
+        .then();                                          <3>
+----
+<1> Using `Person` with the `from(…)` method sets the `FROM` table based on mapping metadata.
+<2> The issued query declares a `WHERE` condition on `firstname` and `lastname` columns to filter rows to delete.
+<3> Use `then()` to just delete rows an object without consuming further details. Modifying statements allow also consumption of the number of affected rows.

Subject: [PATCH 0352/2145] #107 - Add support for
 ConnectionFactoryTransactionManager.ConnectionFactoryTransactionManager.

We now support R2DBC transaction management through ConnectionFactoryTransactionManager which is a ReactiveTransactionManager implementation to be used with TransactionalOperator and Spring's declarative transaction management.

ConnectionFactoryTransactionManager tm = new ConnectionFactoryTransactionManager(connectionFactory);
TransactionalOperator operator = TransactionalOperator.create(tm);
DatabaseClient db = DatabaseClient.create(connectionFactory);

Mono<Void> atomicOperation = db.execute().sql("INSERT INTO person (id, name, age) VALUES(:id, :name, :age)")
            .bind("id", "joe")
            .bind("name", "Joe")
            .bind("age", 34)
            .fetch().rowsUpdated()
            .then(db.execute().sql("INSERT INTO contacts (id, name) VALUES(:id, :name)")
                    .bind("id", "joe")
                    .bind("name", "Joe")
                    .fetch().rowsUpdated())
            .then()
            .as(operator::transactional);

+== Using `ConnectionFactory`
+
+Spring obtains an R2DBC connection to the database through a `ConnectionFactory`.
+A `ConnectionFactory` is part of the R2DBC specification and is a generalized connection factory.
+It lets a container or a framework hide connection pooling and transaction management issues from the application code.
+As a developer, you need not know details about how to connect to the database.
+That is the responsibility of the administrator who sets up the `ConnectionFactory`.
+You most likely fill both roles as you develop and test code, but you do not necessarily have to know how the production data source is configured.
+
+When you use Spring's R2DBC layer, you can can configure your own with a connection pool implementation provided by a third party.
+A popular implementation is R2DBC Pool.
+Implementations in the Spring distribution are meant only for testing purposes and do not provide pooling.
+
+To configure a ``ConnectionFactory``:
+
+. Obtain a connection with `ConnectionFactory` as you typically obtain an R2DBC
+  `ConnectionFactory`.
+. Provide an R2DBC URL. (See the documentation for your driver
+  for the correct value.)
+
+The following example shows how to configure a `ConnectionFactory` in Java:
+
+[source,java,indent=0]
+[subs="verbatim,quotes"]
+----
+	ConnectionFactory factory = ConnectionFactories.get("rdbc:h2:mem:///test?options=DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE");
+----
+
+[[r2dbc.connections.ConnectionFactoryUtils]]
+== Using `ConnectionFactoryUtils`
+
+The `ConnectionFactoryUtils` class is a convenient and powerful helper class that provides `static` methods to obtain connections from `ConnectionFactory` and close connections if necessary.
+It supports subscriber ``Context``-bound connections with, for example `ConnectionFactoryTransactionManager`.
+
+[[r2dbc.connections.SmartConnectionFactory]]
+== Implementing `SmartConnectionFactory`
+
+The `SmartConnectionFactory` interface should be implemented by classes that can provide a connection to a relational database.
+It extends the `ConnectionFactory` interface to let classes that use it query whether the connection should be closed after a given operation.
+This usage is efficient when you know that you need to reuse a connection.
+
+
+[[r2dbc.connections.TransactionAwareConnectionFactoryProxy]]
+== Using `TransactionAwareConnectionFactoryProxy`
+
+`TransactionAwareConnectionFactoryProxy` is a proxy for a target `ConnectionFactory`.
+The proxy wraps that target `ConnectionFactory` to add awareness of Spring-managed transactions.
+
+[[r2dbc.connections.ConnectionFactoryTransactionManager]]
+== Using `ConnectionFactoryTransactionManager`
+
+The `ConnectionFactoryTransactionManager` class is a `ReactiveTransactionManager` implementation for single R2DBC datasources.
+It binds an R2DBC connection from the specified data source to the subscriber `Context`, potentially allowing for one subscriber connection per data source.
+
+Application code is required to retrieve the R2DBC connection through `ConnectionFactoryUtils.getConnection(ConnectionFactory)` instead of R2DBC's standard `ConnectionFactory.create()`.
+All framework classes (such as `DatabaseClient`) use this strategy implicitly.
+If not used with this transaction manager, the lookup strategy behaves exactly like the common one. Thus, it can be used in any case.
+
+The `ConnectionFactoryTransactionManager` class supports custom isolation levels that get applied to the connection.

 A common pattern when using relational databases is grouping multiple queries within a unit of work that is guarded by a transaction.
 Relational databases typically associate a transaction with a single transport connection.
 Using different connections hence results in utilizing different transactions.
-Spring Data R2DBC includes a transactional `DatabaseClient` implementation with `TransactionalDatabaseClient` that allows you to group multiple statements within the same transaction.
-`TransactionalDatabaseClient` is a extension of `DatabaseClient` that exposes the same functionality as `DatabaseClient` and adds transaction-management methods.

-You can run multiple statements within a transaction using the `inTransaction(Function)` closure:
+Spring Data R2DBC includes transaction-awareness in `DatabaseClient` that allows you to group multiple statements within the same transaction using https://docs.spring.io/spring/docs/current/spring-framework-reference/data-access.html#transaction[Spring's Transaction Management].
+Spring Data R2DBC provides a implementation for `ReactiveTransactionManager` with `ConnectionFactoryTransactionManager`.

+ * will associate {@link Connection} with context-bound transactions itself, according to the specified propagation
+ * behavior. It assumes that a separate, independent {@link Connection} can be obtained even during an ongoing
+ * transaction.
+ * <p>
+ * Application code is required to retrieve the R2DBC Connection via
+ * {@link ConnectionFactoryUtils#getConnection(ConnectionFactory)} instead of a standard R2DBC-style
+ * {@link ConnectionFactory#create()} call. Spring classes such as {@link DatabaseClient} use this strategy implicitly.
+ * If not used in combination with this transaction manager, the {@link ConnectionFactoryUtils} lookup strategy behaves
+ * exactly like the native {@link ConnectionFactory} lookup; it can thus be used in a portable fashion.
+ * <p>
+ * Alternatively, you can allow application code to work with the standard R2DBC lookup pattern
+ * {@link ConnectionFactory#create()}, for example for code that is not aware of Spring at all. In that case, define a
+ * {@link TransactionAwareConnectionFactoryProxy} for your target {@link ConnectionFactory}, and pass that proxy
+ * {@link ConnectionFactory} to your DAOs, which will automatically participate in Spring-managed transactions when
+ * accessing it.
+ * <p>
+ * This transaction manager triggers flush callbacks on registered transaction synchronizations (if synchronization is
+ * generally active), assuming resources operating on the underlying R2DBC {@link Connection}.

+/**
+ * Proxy for a target R2DBC {@link ConnectionFactory}, adding awareness of Spring-managed transactions.
+ * <p>
+ * Data access code that should remain unaware of Spring's data access support can work with this proxy to seamlessly
+ * participate in Spring-managed transactions. Note that the transaction manager, for example
+ * {@link ConnectionFactoryTransactionManager}, still needs to work with the underlying {@link ConnectionFactory},
+ * <i>not</i> with this proxy.
+ * <p>
+ * <b>Make sure that {@link TransactionAwareConnectionFactoryProxy} is the outermost {@link ConnectionFactory} of a
+ * chain of {@link ConnectionFactory} proxies/adapters.</b> {@link TransactionAwareConnectionFactoryProxy} can delegate
+ * either directly to the target connection pool or to some intermediary proxy/adapter.
+ * <p>
+ * Delegates to {@link ConnectionFactoryUtils} for automatically participating in thread-bound transactions, for example
+ * managed by {@link ConnectionFactoryTransactionManager}. {@link #create()} calls and {@code close} calls on returned
+ * {@link Connection} will behave properly within a transaction, i.e. always operate on the transactional Connection. If
+ * not within a transaction, normal {@link ConnectionFactory} behavior applies.
+ * <p>
+ * This proxy allows data access code to work with the plain R2DBC API. However, if possible, use Spring's
+ * {@link ConnectionFactoryUtils} or {@link DatabaseClient} to get transaction participation even without a proxy for
+ * the target {@link ConnectionFactory}, avoiding the need to define such a proxy in the first place.
+ * <p>
+ * <b>NOTE:</b> This {@link ConnectionFactory} proxy needs to return wrapped {@link Connection}s (which implement the
+ * {@link ConnectionProxy} interface) in order to handle close calls properly. Use {@link Wrapped#unwrap()} to retrieve
+ * the native R2DBC Connection.

Subject: [PATCH 0353/2145] #107 - Polishing.

Extract method references for better readability. Add missing tests and update documentation.
Add delay for transactional MySql tests to avoid failures due to potentially delayed transaction id storage within the database.

 A common pattern when using relational databases is grouping multiple queries within a unit of work that is guarded by a transaction.
 Relational databases typically associate a transaction with a single transport connection.
 Using different connections hence results in utilizing different transactions.

Subject: [PATCH 0354/2145] #111 - Package and type renames.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Package renames:

- `….domain` -> `….mapping`
- `….function.connectionfactory` -> `connectionfactory`
- `….function.convert` -> `convert`
- `….function.query` -> `query`
- `….function` -> `….core`

Type moves:

- `….dialect.R2dbcSimpleTypeHolder` -> `….mapping.R2dbcSimpleTypeHolder`
- `….mapping.BindTarget` -> `….dialect.BindTarget`
- `….mapping.PreparedOperation` -> `….core.PreparedOperation`
- `….mapping.QueryOperation` -> `….core.QueryOperation`
- `….mapping.BindOperation` -> `….core.BindOperation`
- `….connectionfactory.ConnectionFactoryTransactionManager` -> `….connectionfactory.R2dbcTransactionManager`

That makes us end up with:

- `connectionfactory`
- `core` -> `connectionfactory`, `convert`, `dialect`, `mapping`, `query`
- `query` -> `convert`, `dialect`, `mapping`
- `convert` -> `dialect`, `mapping`
- `dialect` -> `mapping`
- `mapping` -> Spring Data Commons mapping

Reflect type renames in reference documentation.

Subject: [PATCH 0357/2145] DATAJDBC-370 - Fixed handling of entities with no
 withers.

We tried to set all the properties, even when they were already set via constructor.
Fixed it by unifying the three instances where we created and populated instances.

Subject: [PATCH 0359/2145] DATAJDBC-370 - Fix read/write of nulled embedded
 objects.

We now allow read and write of Objects annotated with Embedded that are actually null.
When writing all contained fields will be nulled.
Reading back the entity considers an embedded object to be null itself if all contained properties are null within the backing result.

Relates to DATAJDBC-364

Subject: [PATCH 0370/2145]  #109 - Fix simple type conversion for projection
 queries.

 We now correctly consider built-in converters for simple types that are read through DatabaseClient. Simple type projections typically select a single column and expect a result stream of simple values such as selecting a count and retrieving a Mono<Long>.

 You can configure an own https://docs.spring.io/spring-data/r2dbc/docs/{version}/api/org/springframework/data/r2dbc/dialect/Dialect.html[`Dialect`] if the used driver is not yet known to Spring Data R2DBC.

We compressed client.execute().sql(…) to client.execute(…) to not require the intermediate execute() step but rather accept the SQL to execute directly.

From 097190ee421ef43ca80a785dd8bb0295f868e53e Mon Sep 17 00:00:00 2001

Subject: [PATCH 0383/2145] DATAJDBC-223 - Chains of Lists or Maps get properly
 stored and loaded.

Also solved DATAJDBC-369 since it made refactoring easier.

Known limitation: Back-references to intermediate key columns currently can't get renamed and use the name defined by the property where they become part of the path.

Backward compatibility of the JdbcConfiguration is still broken.

Original pull request: #153.

Subject: [PATCH 0384/2145] DATAJDBC-223 - Polishing.

Simplify conditionals with nested ternary operators. Migrate RelationResolver.findAllBy to returning Iterable of Object instead of T as there is no type contract present. Use Spring utilities where applicable. Simplify tests. Fix warnings, Javadoc, Formatting.

Subject: [PATCH 0385/2145] DATAJDBC-374 - Add onEmpty attribute to Embedded
 annotation.

The onEmpty attribute allows to define if an embedded entity should be set to null or a default instance if all properties backing the entity are actually null.

    @Embedded(onEmpty = USE_NULL)
    EmbeddedEntity embeddedEntity;

Original pull request: #154.

Subject: [PATCH 0399/2145] #104 - Provide extension mechanism for R2dbcDialect
 resolution.

We now use Spring's spring.factories mechanism to register and lookup R2dbcDialectProvider implementations.
This allows a pluggable model for third party implementations to ship R2dbcDialect support that can be auto-discovered.

Original pull request: #127.

+You can let Spring auto-discover your `R2dbcDialect` by registering a class that implements `org.springframework.data.r2dbc.dialect.DialectResolver$R2dbcDialectProvider` through `META-INF/spring.factories`. +
+`DialectResolver` discovers dialect provider implementations from the class path using Spring's `SpringFactoriesLoader`.

 While you need not know the Spring APIs, understanding the concepts behind them is important.
 At a minimum, the idea behind Inversion of Control (IoC) should be familiar, and you should be familiar with whatever IoC container you choose to use.

Subject: [PATCH 0404/2145] #98 - Add support for
 AbstractRoutingConnectionFactory.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We now provide an abstract base class for ConnectionFactory routing. Routing keys are typically obtained from a subscriber context. AbstractRoutingConnectionFactory is backed by either a map of string identifiers or connection factories. When using string identifiers, these can map agains e.g. Spring bean names that can be resolved using BeanFactoryConnectionFactoryLookup.

class MyRoutingConnectionFactory extends AbstractRoutingConnectionFactory {

		@Override
		protected Mono<Object> determineCurrentLookupKey() {
			return Mono.subscriberContext().filter(it -> it.hasKey(ROUTING_KEY)).map(it -> it.get(ROUTING_KEY));
		}
}

@Bean
public void routingConnectionFactory() {

		MyRoutingConnectionFactory router = new MyRoutingConnectionFactory();

		Map<String, ConnectionFactory> factories = new HashMap<>();
		ConnectionFactory myDefault = …;
		ConnectionFactory primary = …;
		ConnectionFactory secondary = …;

		factories.put("primary", primary);
		factories.put("secondary", secondary);

		router.setTargetConnectionFactories(factories);
		router.setDefaultTargetConnectionFactory(myDefault);

		return router;
}

Subject: [PATCH 0406/2145] #105 - Move named parameter resolution to
 ReactiveDataAccessStrategy.

Named parameter resolution is now provided as part of ReactiveDataAccessStrategy. This allows us to hide implementation internals (bind markers). DatabaseClient allows configuration whether to use named parameter expansion.

Detailed configuration of named parameter support is now moved to DefaultReactiveDataAccessStrategy.

Original pull request: #105.

 = Spring Data Relational
 
 The primary goal of the https://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use data access technologies. *Spring Data Relational* offers the popular Repository abstraction based on link:spring-data-jdbc[JDBC].

 This will execute the unit tests, and all the integration tests with all the databases we currently support for testing. Running the integration-tests depends on Docker.
 
+== Running CI tasks locally
+
+Since this pipeline is purely Docker-based, it's easy to:
+
+* Debug what went wrong on your local machine.
+* Test out a a tweak to your `test.sh` script before sending it out.
+* Experiment against a new image before submitting your pull request.
+
+All of these use cases are great reasons to essentially run what the CI server does on your local machine.
+
+IMPORTANT: To do this you must have Docker installed on your machine.
+
+1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-jdbc-github  -v /usr/bin/docker:/usr/bin/docker -v /var/run/docker.sock:/var/run/docker.sock adoptopenjdk/openjdk8:latest /bin/bash`
++
+This will launch the Docker image and mount your source code at `spring-data-jdbc-github`.
++
+2. `cd spring-data-jdbc-github`
++
+Next, test everything from inside the container:
++
+3. `./mvnw -Pci,all-dbs clean dependency:list test -Dsort -B` (or whatever test configuration you must use)
+
+Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
+
+NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

 = Spring Data R2DBC
 
 The primary goal of the https://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use data access technologies. *Spring Data R2DBC* offers the popular Repository abstraction based on https://r2dbc.io[R2DBC].

+== Running CI tasks locally
+
+Since this pipeline is purely Docker-based, it's easy to:
+
+* Debug what went wrong on your local machine.
+* Test out a a tweak to your `test.sh` script before sending it out.
+* Experiment against a new image before submitting your pull request.
+
+All of these use cases are great reasons to essentially run what the CI server does on your local machine.
+
+IMPORTANT: To do this you must have Docker installed on your machine.
+
+1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-r2dbc-github  -v /usr/bin/docker:/usr/bin/docker -v /var/run/docker.sock:/var/run/docker.sock adoptopenjdk/openjdk8:latest /bin/bash`
++
+This will launch the Docker image and mount your source code at `spring-data-r2dbc-github`.
++
+2. `cd spring-data-r2dbc-github`
++
+Next, test everything from inside the container:
++
+3. `./mvnw -Pci,all-dbs clean dependency:list test -Dsort -B` (or whatever test configuration you must use)
+
+Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
+
+NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

Subject: [PATCH 0415/2145] DATAJDBC-384 - Fixed
 MyBatisDataAccessStrategy.findAllByPath.

findAllByPath now falls back to the older findAllByProperty for better backward compatibility.
Also the path is included in the query name used for MyBatis.

 Instead, the mechanics of `JdbcTemplate` to issue SQL statements provide logging.

Subject: [PATCH 0432/2145] #145 - Register R2DBC Repository factory in
 spring.factories.

We now register R2dbcRepositoryFactory as repository factory to aid Spring Data's multi-store detection so Spring Data enters strict config mode when multiple modules are on the class path.

+== Running CI tasks locally
+
+Since this pipeline is purely Docker-based, it's easy to:
+
+* Debug what went wrong on your local machine.
+* Test out a a tweak to your `test.sh` script before sending it out.
+* Experiment against a new image before submitting your pull request.
+
+All of these use cases are great reasons to essentially run what the CI server does on your local machine.
+
+IMPORTANT: To do this you must have Docker installed on your machine.
+
+1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-jdbc-github  -v /usr/bin/docker:/usr/bin/docker -v /var/run/docker.sock:/var/run/docker.sock adoptopenjdk/openjdk8:latest /bin/bash`
++
+This will launch the Docker image and mount your source code at `spring-data-jdbc-github`.
++
+2. `cd spring-data-jdbc-github`
++
+Next, test everything from inside the container:
++
+3. `./mvnw -Pci,all-dbs clean dependency:list test -Dsort -B` (or whatever test configuration you must use)
+
+Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
+
+NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

-=== Run tests with all databases
+== Reporting Issues
 
-[source]
-----
-$ mvn test -Pall-dbs
-----
+Spring Data uses JIRA as issue tracking system to record bugs and feature requests. If you want to raise an issue, please follow the recommendations below:
+
+* Before you log a bug, please search the
+https://jira.spring.io/browse/DATAJDBC[issue tracker] to see if someone has already reported the problem.
+* If the issue doesn’t already exist, https://jira.spring.io/browse/DATAJDBC[create a new issue].
+* Please provide as much information as possible with the issue report, we like to know the version of Spring Data that you are using and JVM version.
+* If you need to paste code, or include a stack trace use JIRA `{code}…{code}` escapes before and after your text.
+* If possible try to create a test-case or project that replicates the issue. Attach a link to your code or a compressed file containing your code.
+
+== Building from Source
 
-This will execute the unit tests, and all the integration tests with all the databases we currently support for testing. Running the integration-tests depends on Docker.
+You don’t need to build from source to use Spring Data (binaries in https://repo.spring.io[repo.spring.io]), but if you want to try out the latest and greatest, Spring Data can be easily built with the https://github.com/takari/maven-wrapper[maven wrapper].
+You also need JDK 1.8.
 
-== Running CI tasks locally
+[source,bash]
+----
+ $ ./mvnw clean install

-Since this pipeline is purely Docker-based, it's easy to:
+If you want to build with the regular `mvn` command, you will need https://maven.apache.org/run-maven/index.html[Maven v3.5.0 or above].
 
-* Debug what went wrong on your local machine.
-* Test out a a tweak to your `test.sh` script before sending it out.
-* Experiment against a new image before submitting your pull request.
+_Also see link:CONTRIBUTING.adoc[CONTRIBUTING.adoc] if you wish to submit pull requests, and in particular please sign the https://cla.pivotal.io/sign/spring[Contributor’s Agreement] before your first change, is trivial._
 
-All of these use cases are great reasons to essentially run what the CI server does on your local machine.
+=== Building reference documentation
 
-IMPORTANT: To do this you must have Docker installed on your machine.
+Building the documentation builds also the project without running tests.
 
-1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-jdbc-github  -v /usr/bin/docker:/usr/bin/docker -v /var/run/docker.sock:/var/run/docker.sock adoptopenjdk/openjdk8:latest /bin/bash`
-+
-This will launch the Docker image and mount your source code at `spring-data-jdbc-github`.
-+
-2. `cd spring-data-jdbc-github`
-+
-Next, test everything from inside the container:
-+
-3. `./mvnw -Pci,all-dbs clean dependency:list test -Dsort -B` (or whatever test configuration you must use)
+[source,bash]
+----
+ $ ./mvnw clean install -Pdistribute
+----
 
-Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
+The generated documentation is available from `target/site/reference/html/index.html`.
 
-NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

+== Running CI tasks locally
+
+Since this pipeline is purely Docker-based, it's easy to:
+
+* Debug what went wrong on your local machine.
+* Test out a a tweak to your `test.sh` script before sending it out.
+* Experiment against a new image before submitting your pull request.
+
+All of these use cases are great reasons to essentially run what the CI server does on your local machine.
+
+IMPORTANT: To do this you must have Docker installed on your machine.
+
+1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-r2dbc-github  -v /usr/bin/docker:/usr/bin/docker -v /var/run/docker.sock:/var/run/docker.sock adoptopenjdk/openjdk8:latest /bin/bash`
++
+This will launch the Docker image and mount your source code at `spring-data-r2dbc-github`.
++
+2. `cd spring-data-r2dbc-github`
++
+Next, test everything from inside the container:
++
+3. `./mvnw -Pci,all-dbs clean dependency:list test -Dsort -B` (or whatever test configuration you must use)
+
+Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
+
+NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

 The primary goal of the https://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use data access technologies. *Spring Data R2DBC* offers the popular Repository abstraction based on https://r2dbc.io[R2DBC].
 
 R2DBC is the abbreviation for https://github.com/r2dbc/[Reactive Relational Database Connectivity], an incubator to integrate relational databases using a reactive driver.
 
-The state of R2DBC is incubating to evaluate how an reactive integration could look like. To get started, you need a R2DBC driver first.
-
 == This is NOT an ORM
 
-Spring Data R2DBC does not try to be an ORM.
-Instead it is more of a construction kit for your personal reactive relational data access component that you can define the way you like or need it.
+Spring Data R2DBC aims at being conceptually easy. In order to achieve this it does NOT offer caching, lazy loading, write behind or many other features of ORM frameworks. This makes Spring Data R2DBC a simple, limited, opinionated object mapper.
 
-== Maven Coordinates
+== Features
 
-[source,xml]
-----
-<dependency>
-    <groupId>org.springframework.data</groupId>
-    <artifactId>spring-data-r2dbc</artifactId>
-    <version>1.0.0.BUILD-SNAPSHOT</version>
-</dependency>
-----
+* Spring configuration support using Java based `@Configuration` classes.
+* Annotation based mapping metadata.
+* Automatic implementation of Repository interfaces including support.
+* Support for Reactive Transactions
+* Schema and data initialization utilities.
 
+== Code of Conduct
 
-== DatabaseClient
+This project is governed by the link:CODE_OF_CONDUCT.adoc[Spring Code of Conduct]. By participating, you are expected to uphold this code of conduct. Please report unacceptable behavior to spring-code-of-conduct@pivotal.io.
 
-All functionality is encapsulated in `DatabaseClient` which is the entry point for applications that wish to integrate with relational databases using reactive drivers:
+== Getting Started
 
-[source,java]
-----
-PostgresqlConnectionFactory connectionFactory = new PostgresqlConnectionFactory(PostgresqlConnectionConfiguration.builder()
-		.host(…)
-		.database(…)
-		.username(…)
-		.password(…).build());
+Here is a quick teaser of an application using Spring Data Repositories in Java:
 
-DatabaseClient databaseClient = DatabaseClient.create(connectionFactory);
+[source,java]
 ----
+public interface PersonRepository extends CrudRepository<Person, Long> {
 
-The client API provides covers the following features:
-
-* Execution of generic SQL and consumption of update count/row results.
-* Generic `SELECT` with paging and ordering.
-* `SELECT` of mapped objects with paging and ordering.
-* Generic `INSERT` with parameter binding.
-* `INSERT` of mapped objects.
-* Parameter binding using the native syntax.
-* Result consumption: Update count, unmapped (`Map<String, Object>`), mapped to entities, extraction function.
-* Reactive repositories using `@Query` annotated methods.
-* Transaction Management.
-
-=== Examples executing generic SQL statements
+	@Query("SELECT * FROM person WHERE lastname = :lastname")
+  Flux<Person> findByLastname(String lastname);
 
-[source,java]
-----
-Mono<Integer> count = databaseClient.execute()
-				.sql("INSERT INTO legoset (id, name, manual) VALUES($1, $2, $3)")
-				.bind("$1", 42055)
-				.bind("$2", "Description")
-				.bindNull("$3", Integer.class)
-				.fetch()
-				.rowsUpdated();
-
-Flux<Map<String, Object>> rows = databaseClient.execute()
-				.sql("SELECT id, name, manual FROM legoset")
-				.fetch()
-				.all();
-
-Flux<Long> result = db.execute()
-				.sql("SELECT txid_current();")
-				.map((r, md) -> r.get(0, Long.class))
-				.all();
-----
+	@Query("SELECT * FROM person WHERE firstname LIKE :lastname")
+  Flux<Person> findByFirstnameLike(String firstname);
+}
 
-=== Examples selecting data
+@Service
+public class MyService {
 
-[source,java]
-----
+  private final PersonRepository repository;
 
-Flux<Map<String, Object>> rows = databaseClient.select()
-				.from("legoset")
-				.orderBy(Sort.by(desc("id")))
-				.fetch()
-				.all();
-
-Flux<LegoSet> rows = databaseClient.select()
-				.from("legoset")
-				.orderBy(Sort.by(desc("id")))
-				.as(LegoSet.class)
-				.fetch()
-				.all();
-----
+  public MyService(PersonRepository repository) {
+    this.repository = repository;
+  }
 
-=== Examples inserting data
+  public void doWork() {
 
-[source,java]
-----
-Flux<Integer> ids = databaseClient.insert()
-				.into("legoset")
-				.value("id", 42055)
-				.value("name", "Description")
-				.nullValue("manual", Integer.class)
-				.map((r, m) -> r.get("id", Integer.class)
-				.all();
-
-Mono<Void> completion = databaseClient.insert()
-				.into(LegoSet.class)
-				.using(legoSet)
-				.then();
-----
+    repository.deleteAll().block();
 
-=== Examples using reactive repositories
+    Person person = new Person();
+    person.setFirstname("Mark");
+    person.setLastname("Paluch");
+    repository.save(person).block();
 
-[source,java]
-----
-interface LegoSetRepository extends ReactiveCrudRepository<LegoSet, Integer> {
+    Flux<Person> lastNameResults = repository.findByLastname("Paluch");
+    Flux<Person> firstNameResults = repository.findByFirstnameLike("M%");
+ }
+}
 
-		@Query("SELECT * FROM legoset WHERE name like $1")
-		Flux<LegoSet> findByNameContains(String name);
+@Configuration
+@EnableR2dbcRepositories
+class ApplicationConfig extends AbstractR2dbcConfiguration {
 
-		@Query("SELECT * FROM legoset WHERE manual = $1")
-		Mono<LegoSet> findByManual(int manual);
+  @Bean
+  public ConnectionFactory connectionFactory() {
+    return ConnectionFactories.get("r2dbc:h2:mem:///test?options=DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE");
+  }
 }
 ----
 
-=== Examples using transaction control
+=== Maven configuration
 
-All examples above run with auto-committed transactions. To get group multiple statements within the same transaction or
-control the transaction yourself, you need to use `TransactionalDatabaseClient`:
+Add the Maven dependency:
 
-[source,java]
+[source,xml]
 ----
-TransactionalDatabaseClient databaseClient = TransactionalDatabaseClient.create(connectionFactory);
+<dependency>
+  <groupId>org.springframework.data</groupId>
+  <artifactId>spring-data-r2dbc</artifactId>
+  <version>${version}.RELEASE</version>
+</dependency>
 ----
 
-`TransactionalDatabaseClient` allows multiple flavors of transaction management:
+If you'd rather like the latest snapshots of the upcoming major version, use our Maven snapshot repository and declare the appropriate dependency version.
 
-* Participate in ongoing transactions and fall-back to auto-commit mode if there's no active transaction (default).
-* Group multiple statements in a managed transaction using `TransactionalDatabaseClient.inTransaction(…)`.
-* Application-controlled transaction management using `TransactionalDatabaseClient.beginTransaction()`/`commitTransaction()`/`rollbackTransaction()`.
+[source,xml]
+----
+<dependency>
+  <groupId>org.springframework.data</groupId>
+  <artifactId>spring-data-r2dbc</artifactId>
+  <version>${version}.BUILD-SNAPSHOT</version>
+</dependency>
 
-Participating in ongoing transactions does not require changes to your application code. Instead, a managed transaction must be hosted by your application container. Transaction control needs to happen there, as well.
+<repository>
+  <id>spring-libs-snapshot</id>
+  <name>Spring Snapshot Repository</name>
+  <url>https://repo.spring.io/libs-snapshot</url>
+</repository>
+----
 
-**Statement grouping**
+== Getting Help
 
-[source,java]
-----
-Flux<Integer> rowsUpdated = databaseClient.inTransaction(db -> {
-
-	return db.execute().sql("INSERT INTO legoset (id, name, manual) VALUES($1, $2, $3)") //
-			.bind(0, 42055) //
-			.bind(1, "Description") //
-			.bindNull("$3", Integer.class) //
-			.fetch()
-			.rowsUpdated();
-});
-----
+Having trouble with Spring Data? We’d love to help!

-				.flatMapMany(it -> it.map((r, md) -> r.get(0, Long.class)).all());
+== Reporting Issues
 
-Mono<Void> then = databaseClient.enableTransactionSynchronization(databaseClient.beginTransaction() //
-				.thenMany(txId)) //
-				.then(databaseClient.rollbackTransaction()));
-----

Subject: [PATCH 0443/2145] DATAJDBC-395 - Overhaul of
 AbstractJdbcConfiguration.

We now declare DataAccessStrategy as bean again as using a custom default caused the lazy resolution of a RelationResolver to break. Changed the signatures to avoid cross method invocations and allow us to declare the class to not need proxying.

Added integration tests to make sure the components that should be registered are actually registered and the configuration class is useable in the first place. With that in place, the broken cycle would've been caught immediately.

Subject: [PATCH 0444/2145] DATAJDBC-395 - Added dedicated configuration class
 for MyBatis integration.

We now ship MyBatisJdbcConfiguration as an alternative to (Abstract)JdbcConfiguration to tweak the DataAccessStrategy bean registered to create one that tries MyBatis mappings first but still delegates to the default one.

 == MyBatis Integration
 
+The execution of CRUD operations and query methods can be delegated to MyBatis.
+This section describes how to configure Spring Data JDBC to integrate with MyBatis and which conventions to follow to hand over the execution of the queries as well as the mapping to the library.
+
+[[jdbc.mybatis.configuration]]
+== Configuration
+
+The easiest way to properly plug MyBatis into Spring Data JDBC is by importing `MyBatisJdbcConfiguration` into you application configuration:
+
+[source, java]
+----
+@Configuration
+@EnableJdbcRepositories
+@Import(MyBatisJdbcConfiguration.class)
+class Application {
+
+  @Bean
+  SqlSessionFactoryBean sqlSessionFactoryBean() {
+    // Configure MyBatis here
+  }
+}
+----
+
+As you can see, all you need to declare is a `SqlSessionFactoryBean` as `MyBatisJdbcConfiguration` relies on a `SqlSession` bean to be available in the `ApplicationContext` eventually.
+
+[[jdbc.mybatis.conventions]]
+== Usage conventions
+
 For each operation in `CrudRepository`, Spring Data JDBC runs multiple statements.
 If there is a https://github.com/mybatis/mybatis-3/blob/master/src/main/java/org/apache/ibatis/session/SqlSessionFactory.java[`SqlSessionFactory`] in the application context, Spring Data checks, for each step, whether the `SessionFactory` offers a statement.
 If one is found, that statement (including its configured mapping to an entity) is used.

Subject: [PATCH 0445/2145] DATAJDBC-390 - Add ordering to
 RelationalAuditingEventListener to run before other listeners without
 explicitly specified order.

When an event listener is used to set an id before saving it, this ensures the auditing happens before setting the id.
If this is not ensured the auditing listener doesn't consider the entity as new and doesn't set created date and created by user.

- * {@link DatabaseClient} that participates in an ongoing transaction if the subscription happens within a hosted
- * transaction. Alternatively, transactions can be started and cleaned up using {@link #beginTransaction()} and

- * <p>
- * Transactional resources are bound to
- * {@link org.springframework.data.r2dbc.connectionfactory.ReactiveTransactionSynchronization} through nested
- * {@link TransactionContext} enabling nested (parallel) transactions. The simplemost approach to use transactions is by
- * using {@link #inTransaction(Function)} which will start a transaction and commit it on successful termination. The
- * callback allows execution of multiple statements within the same transaction.
- *
- * <pre class="code">
- * Flux<Integer> transactionalFlux = databaseClient.inTransaction(db -> {
- *
- * 	return db.execute("INSERT INTO person (id, firstname, lastname) VALUES(:id, :firstname, :lastname)") //
- * 			.bind("id", 1) //
- * 			.bind("firstname", "Walter") //
- * 			.bind("lastname", "White") //
- * 			.fetch().rowsUpdated();
- * });
- * </pre>
- *
- * Alternatively, transactions can be controlled by using {@link #beginTransaction()} and {@link #commitTransaction()}
- * methods. This approach requires {@link #enableTransactionSynchronization(Publisher) enabling of transaction
- * synchronization} for the transactional operation.
- *
- * <pre class="code">
- * Mono<Void> mono = databaseClient.beginTransaction()
- * 		.then(databaseClient.execute()
- * 				.execute("INSERT INTO person (id, firstname, lastname) VALUES(:id, :firstname, :lastname)") //
- * 				.bind("id", 1) //

Subject: [PATCH 0450/2145] #103 - Coroutines extensions throw proper
 EmptyResultDataAccessException.

RowsFetchSpec.awaitOne() and RowsFetchSpec.awaitFirst() now throw EmptyResultDataAccessException instead of NoSuchElementException to consistently use Spring DAO exceptions.

Subject: [PATCH 0451/2145] #138 - Allow multiple usages of the same named
 parameter.

We now allow multiple usages of the same named parameter if the underlying database supports identifiable placeholders.

SELECT * FROM person where name = :id or lastname = :id

gets translated to

SELECT * FROM person where name = $1 or lastname = $1

Subject: [PATCH 0453/2145] DATAJDBC-393 - EntityCallback support.

An `EntityCallback` works very similar to an `ApplicationEvent` but returns a potentially changed instance.
The returned instance will be used in further processing which enables proper event handling for immutable classes.

Auditing was changed to use a callback making it work also with immutable objects.

Original pull request: #161.

From: Mark Paluch <mpaluch@pivotal.io>
Date: Tue, 16 Jul 2019 11:13:25 +0200
Subject: [PATCH 0454/2145] DATAJDBC-393 - Polishing.

Accept AggregateChange in BeforeSave and BeforeDelete callbacks. Add Javadoc. Fix generics usage in RelationalAuditingCallback. Align documentation for consistent entity callback documentation.

Add overloaded JdbcAggregateTemplate constructor to directly configure EntityCallbacks.

Original pull request: #161.

Subject: [PATCH 0455/2145] DATAJDBC-394 - Don't use AS for table aliases.

The AS keyword for table aliases is optional for all databases that support it.
It is not supported by Oracle.
Thus not using it makes the generated SQL compatible to more databases.

Subject: [PATCH 0467/2145] DATAJDBC-399 - Performance improvements in metadata
 lookups.

Avoid Stream usage in favor of a simple for loop in event triggering in JdbcAggregateTemplate. Tweaked JdbcMappingContext to verify the presence of parameter names on metadata creation. Avoid the re-resolution of the column name for a property by caching the resolved column name. This significantly improves performance as it avoids repeated parsing and concatenation of strings. Added caching to PersistentPropertyPathExtension.

Subject: [PATCH 0477/2145] DATAJDBC-405 - Fixes asciidoctor includes.

Includes from Spring Data Commons failed because they where made relative from the asciidoc documents.
But the documents get moved before asciidoc is executed.

Corrected the environment variable used for building the reference to account for this.
Removed one manual fix which breaks with the proper fix.

Subject: [PATCH 0484/2145] #169 - Allow usage of Entity-level converters.

We now support Converters on Entity-level if object materialization/dematerialization is handled by application code. We're using a custom R2DBC MappingContext to create mapping metadata for types that have custom converters registered.

Subject: [PATCH 0485/2145] #162 - Refine declaration of nullable values in
 DatabaseClient.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

DatabaseClient.BindSpec.bind(…) (execute) and DatabaseClient.GenericInsertSpec.value(…) (insert) now consistently accept SettableValue for scalar and absent values.

This change allows us to provide a Kotlin extension leveraging reified generics to provide the type of a value even if it is null to construct an appropriate SettableValue for fluent API usage.

 == What is R2DBC?
 
-https://r2dbc.io[R2DBC] is the acronym for Reactive Relational Database Connectivity. R2DBC is an API specification initiative that declares a reactive API to be implemented by driver vendors for accessing their relational databases.
+https://r2dbc.io[R2DBC] is the acronym for Reactive Relational Database Connectivity.
+R2DBC is an API specification initiative that declares a reactive API to be implemented by driver vendors to access their relational databases.
 
-Part of the answer why R2DBC was created is the need for a non-blocking application stack to handle concurrency with a small number of threads and scale with fewer hardware resources.
-This need cannot be satisfied with reusing standardized relational database access APIs - namely JDBC – as JDBC is a fully blocking API.
-Attempts to compensate for blocking behavior with a `ThreadPool` are limited useful.
+Part of the answer as to why R2DBC was created is the need for a non-blocking application stack to handle concurrency with a small number of threads and scale with fewer hardware resources.
+This need cannot be satisfied by reusing standardized relational database access APIs -- namely JDBC –- as JDBC is a fully blocking API.
+Attempts to compensate for blocking behavior with a `ThreadPool` are of limited use.
 
 The other part of the answer is that most applications use a relational database to store their data.
 While several NoSQL database vendors provide reactive database clients for their databases, migration to NoSQL is not an option for most projects.
 This was the motivation for a new common API to serve as a foundation for any non-blocking database driver.
-While the open source ecosystem hosts various non-blocking relational database driver implementations, each client comes with a vendor-specific API so a generic layer on top of these libraries is not possible.

 [[get-started:first-steps:reactive]]
 == What is Reactive?
 
-The term, reactive refers to programming models that are built around reacting to change, availability, and processability — network components reacting to I/O events, UI controllers reacting to mouse events, resources being made available and others.
+The term, "`b`", refers to programming models that are built around reacting to change, availability, and processability -— network components reacting to I/O events, UI controllers reacting to mouse events, resources being made available, and others.
 In that sense, non-blocking is reactive, because, instead of being blocked, we are now in the mode of reacting to notifications as operations complete or data becomes available.
 
-There is also another important mechanism that we on the Spring team associated with reactive and that is non-blocking back pressure.
+There is also another important mechanism that we on the Spring team associate with reactive, and that is non-blocking back pressure.
 In synchronous, imperative code, blocking calls serve as a natural form of back pressure that forces the caller to wait.
 In non-blocking code, it becomes essential to control the rate of events so that a fast producer does not overwhelm its destination.
 
 https://github.com/reactive-streams/reactive-streams-jvm/blob/v{reactiveStreamsVersion}/README.md#specification[Reactive Streams is a small spec] (also https://docs.oracle.com/javase/9/docs/api/java/util/concurrent/Flow.html[adopted in Java 9]) that defines the interaction between asynchronous components with back pressure.
-For example, a data repository (acting as {reactiveStreamsJavadoc}/org/reactivestreams/Publisher.html[`Publisher`]) can produce data that an HTTP server (acting as {reactiveStreamsJavadoc}/org/reactivestreams/Subscriber.html`[`Subscriber`]) can then write to the response.

 The main purpose of Reactive Streams is to let the subscriber control how quickly or how slowly the publisher produces data.

 == Reactive API
 
 Reactive Streams plays an important role for interoperability. It is of interest to libraries and infrastructure components but less useful as an application API, because it is too low-level.
-Applications need a higher-level and richer, functional API to compose async logic — similar to the Java 8 Stream API but not only for tables.

 This is the role that reactive libraries play.
 
 https://github.com/reactor/reactor[Project Reactor] is the reactive library of choice for Spring Data R2DBC.
 It provides the https://projectreactor.io/docs/core/release/api/reactor/core/publisher/Mono.html[`Mono`] and https://projectreactor.io/docs/core/release/api/reactor/core/publisher/Flux.html[`Flux`] API types to work on data sequences of `0..1` (`Mono`) and `0..N` (`Flux`) through a rich set of operators aligned with the ReactiveX vocabulary of operators.
-Reactor is a Reactive Streams library and, therefore, all of its operators support non-blocking back pressure.

+Spring Data R2DBC requires Project Reactor as a core dependency, but it is interoperable with other reactive libraries through the  Reactive Streams specification.
 As a general rule, a Spring Data R2DBC repository accepts a plain `Publisher` as input, adapts it to a Reactor type internally, uses that, and returns either a `Mono` or a `Flux` as output.

 The mapping subsystem allows the customization of the object construction by annotating a constructor with the `@PersistenceConstructor` annotation. The values to be used for the constructor parameters are resolved in the following way:
 
-* If a parameter is annotated with the `@Value` annotation, the given expression is evaluated and the result is used as the parameter value.
-* If the Java type has a property whose name matches the given field of the input row, then it's property information is used to select the appropriate constructor parameter to pass the input field value to. This works only if the parameter name information is present in the java `.class` files which can be achieved by compiling the source with debug information or using the `-parameters` command-line switch for javac in Java 8.
-* Otherwise a `MappingException` will be thrown indicating that the given constructor parameter could not be bound.

+The term, "`reactive`", refers to programming models that are built around reacting to change, availability, and processability -— network components reacting to I/O events, UI controllers reacting to mouse events, resources being made available, and others.
 In that sense, non-blocking is reactive, because, instead of being blocked, we are now in the mode of reacting to notifications as operations complete or data becomes available.
 
 There is also another important mechanism that we on the Spring team associate with reactive, and that is non-blocking back pressure.

Subject: [PATCH 0516/2145] #181 - Remove repositories declaration from
 published pom.

We now use the Maven flatten plugin to remove repositories from the POM.

Also remove Java 8 from TravisCI as Java 8 can no longer be installed on Travis.

 entities.

We now exclude byte[] properties from being mapped to array types. To map data to a 1-dimensional BYTE[] Postgres type, properties can be declared as Collection<Byte> or Byte[].

Subject: [PATCH 0523/2145] #178 - Consider named and indexed parameters for
 named parameter processing.

Named parameters can be provided by name and by index. Repository query methods bind parameters by name if a named parameter can be found.

If parameters are bound by index, then the parameter name is looked up by index (index corresponds with the order of parameter name discovery when parsing the query). and bound to the parameter.

+[[r2dbc.init]]
+= Initializing a `ConnectionFactory`
+
+The `org.springframework.data.r2dbc.connectionfactory.init` package provides support for initializing an existing `ConnectionFactory`.
+You may sometimes need to initialize an instance that runs on a server somewhere or an embedded database.
+
+== Initializing a Database by Using @Bean methods
+
+If you want to initialize a database and you can provide a reference to a `ConnectionFactory` bean, you can use the
+
+.Using `ConnectionFactoryInitializer` to initialize a `ConnectionFactory`
+====
+[source,java]
+----
+@Configuration
+public class InitializerConfiguration {
+
+	@Bean
+	public ConnectionFactoryInitializer initializer(ConnectionFactory connectionFactory) {
+
+		ConnectionFactoryInitializer initializer = new ConnectionFactoryInitializer();
+		initializer.setConnectionFactory(connectionFactory);
+
+		CompositeDatabasePopulator populator = new CompositeDatabasePopulator();
+		populator.addPopulators(new ResourceDatabasePopulator(new ClassPathResource("com/foo/sql/db-schema.sql")));
+		populator.addPopulators(new ResourceDatabasePopulator(new ClassPathResource("com/foo/sql/test-data1.sql")));
+		initializer.setDatabasePopulator(populator);
+
+		return initializer;
+	}
+}
+----
+====
+
+The preceding example runs the two specified scripts against the database.
+The first script creates a schema, and the second populates tables with a test data set.
+
+The default behavior of the database initializer is to unconditionally run the provided scripts.
+This may not always be what you want — for instance, if you run the scripts against a database that already has test data in it.
+The likelihood of accidentally deleting data is reduced by following the common pattern (shown earlier) of creating the tables first and then inserting the data.
+The first step fails if the tables already exist.
+
+However, to gain more control over the creation and deletion of existing data, `ConnectionFactoryInitializer` and `ResourceDatabasePopulator` support various switches such as switching the initialization on and off.
+
+Each statement should be separated by `;` or a new line if the `;` character is not present at all in the script. You can control that globally or script by script, as the following example shows:
+
+.Customizing statement separators
+====
+[source,java]
+----
+@Configuration
+public class InitializerConfiguration {
+
+	@Bean
+	public ConnectionFactoryInitializer initializer(ConnectionFactory connectionFactory) {
+
+		ConnectionFactoryInitializer initializer = new ConnectionFactoryInitializer();
+
+		initializer.setConnectionFactory(connectionFactory);
+
+		ResourceDatabasePopulator populator = new ResourceDatabasePopulator(new ClassPathResource("com/foo/sql/db-schema.sql"));
+		populator.setSeparator("@@");                                                <1>
+		initializer.setDatabasePopulator(populator);
+
+		return initializer;
+	}
+}
+----
+<1> Set the separator scripts to `@@`.
+====
+
+In this example, the schema scripts uses `@@` as statement separator.
+
+=== Initialization of Other Components that Depend on the Database
+
+A large class of applications (those that do not use the database until after the Spring context has started) can use the database initializer with no further complications.
+If your application is not one of those, you might need to read the rest of this section.
+
+The database initializer depends on a `ConnectionFactory` instance and runs the scripts provided in its initialization callback (analogous to an `init-method` in an XML bean definition, a `@PostConstruct` method in a component, or the `afterPropertiesSet()` method in a component that implements `InitializingBean`).
+If other beans depend on the same data source and use the data source in an initialization callback, there might be a problem because the data has not yet been initialized.
+A common example of this is a cache that initializes eagerly and loads data from the database on application startup.
+
+To get around this issue, you have two options:
+
+1. change your cache initialization strategy to a later phase or
+2. ensure that the database initializer is initialized first
+
+Changing your cache initialization strategy might be easy if the application is in your control and not otherwise. Some suggestions for how to implement this include:
+
+* Make the cache initialize lazily on first usage, which improves application startup time.
+* Have your cache or a separate component that initializes the cache implement Lifecycle or SmartLifecycle.
+When the application context starts, you can automatically start a `SmartLifecycle` by setting its `autoStartup` flag, and you can manually start a Lifecycle by calling `ConfigurableApplicationContext.start()` on the enclosing context.
+* Use a Spring `ApplicationEvent` or similar custom observer mechanism to trigger the cache initialization.
+`ContextRefreshedEvent` is always published by the context when it is ready for use (after all beans have been initialized), so that is often a useful hook (this is how the `SmartLifecycle` works by default).
+
+Ensuring that the database initializer is initialized first can also be easy.
+Some suggestions on how to implement this include:
+
+* Rely on the default behavior of the Spring `BeanFactory`, which is that beans are initialized in registration order.
+You can easily arrange that by adopting the common practice of a set of `@Import` configuration that order your application modules and ensuring that the database and database initialization are listed first.
+* Separate the `ConnectionFactory` and the business components that use it and control their startup order by putting them in separate `ApplicationContext` instances (for example, the parent context contains the `ConnectionFactory`, and the child context contains the business components).

Date: Tue, 15 Oct 2019 15:52:19 +0200
Subject: [PATCH 0550/2145] DATAJDBC-291 - Polishing.

Introduce factory methods for AggregateChange save/delete object creation. Replace computeIfAbsent pattern with appropriate methods. Add indirection for staged values traversal. Rename CascadingValuesLookup to StagedValues.
Javadoc, formatting.

Subject: [PATCH 0551/2145] #209 - Provide extensions on TypedExecuteSpec and
 GenericExecuteSpec.

The original extensions did not allow for executing fetch operations because they where on BindSpec.

Original pull request: #210.

 =?UTF-8?q?ConnectionFactoryInitializer.execute(=E2=80=A6).?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ConnectionFactoryInitializer.execute(…) now calls .block() to subscribe to database initializer and database cleaner.

Previously, the resulting Mono wasn't subscribed to and the database was not initialized.

Subject: [PATCH 0567/2145] DATAJDBC-437 - In strict mode we only claim
 repositories for domain types with @Table annotation.

Before this change Spring Data JDBC didn't specify any identifying annotation and therefore would claim all or no repository depending on the the version of Spring Data Commons.

Also added the RepositoryFactorySupport to spring.factory in order to support detection of multiple RepositoryFactorySupport implementations on the classpath.

Related ticket: DATACMNS-1596.
Original pull request: #177.

Subject: [PATCH 0569/2145] DATAJDBC-431 - ReadOnlyProperty now no longer
 written.

The problem was that the SqlGenerator honored the annotation but they were included as query parameters and therefore automatically added back again.

Also:

* Simplified the relevant filter in the SqlGenerator.
* Introduced a meta annotation for running tests only agains HsqlDb.

Subject: [PATCH 0578/2145] DATAJDBC-417 - Fixed saving an entity containing a
 null embeddable with a reference to a further entity.

Constructing the DbActions assumed that the parent of a path exists (i.e. is not null) and created parent nodes.

We now support returning the affected rows count for repository query methods that are annotated with the Modifying annotation. A modifying query method can return either the affected row count, a boolean value whether at least one row was updated or suppress value emission.

    @Query("UPDATE person SET firstname = :firstname where lastname = :lastname")
    Mono<Integer> setFixedFirstnameFor(String firstname, String lastname);

+[[r2dbc.repositories.modifying]]
+=== Modifying Queries
+
+The previous sections describe how to declare queries to access a given entity or collection of entities.
+You can add custom modifying behavior by using the facilities described in <<repositories.custom-implementations,Custom Implementations for Spring Data Repositories>>.
+As this approach is feasible for comprehensive custom functionality, you can modify queries that only need parameter binding by annotating the query method with `@Modifying`, as shown in the following example:
+
+Declaring manipulating queries
+
+====
+[source,java]
+----
+@Query("UPDATE person SET firstname = :firstname where lastname = :lastname")
+Mono<Integer> setFixedFirstnameFor(String firstname, String lastname);
+----
+====
+
+The result of a modifying query can be:
+
+* `Void` to discard update count and await completion
+* `Integer` emitting the affected rows count

Subject: [PATCH 0591/2145] #235 - Polishing.

Added test and tweaked documentation to clarify that other numeric types beyond `Integer` are admissible.
Split a test in order to have meaningful test names.

Subject: [PATCH 0594/2145] DATAJDBC-219 - Implements optimistic record
 locking.

Optimistic locking is based on a numeric attribute annotated with `@Version` on the aggregate root.
That attribute is increased before any save operation and checked during updates to ensure that the database state hasn't changed since loading the aggregate.

Original pull request: #166.

+=== Optimistic Locking
+
+Spring Data JDBC supports optimistic locking by means of a numeric attribute that is annotated with
+ https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Version.html[`@Version`] on the aggregate root.
+Whenever Spring Data JDBC saves an aggregate with such a version attribute two things happen:
+The update statement for the aggregate root will contain a where clause checking that the version stored in the database is actually unchanged.
+If this isn't the case an `OptimisticLockingFailureException` will be thrown.
+Also the version attribute gets increased both in the entity and in the database so a concurrent action will notice the change and throw an `OptimisticLockingFailureException` if applicable as described above.
+
+This process also applies to inserting new aggregates, where a `null` or `0` version indicates a new instance and the increased instance afterwards marks the instance as not new anymore, making this work rather nicely with cases where the id is generated during object construction for example when UUIDs are used.
+
+During deletes the version check also applies but no version is increased.

Subject: [PATCH 0606/2145] #139 - Consider value type in Dialect-specific
 array type conversion.

We now inspect the value type of a SettableValue before attempting to convert a value into an array type. This check allows applying custom conversions to map objects to a simple type and bypassing the array conversion afterwards.

Previously, we just relied on the property type without checking whether the value qualifies for array type conversion.

Subject: [PATCH 0622/2145] DATAJDBC-234 - Adds support for named queries
 stored in property files.

Queries are expected in a properties file on the classpath `META-INF/jdbc-named-queries.properties`.
The name of the query is by default `<simple class name of the domain type>.<methodName>`.
Alternatively it can be set using the `@Query` annotations `name` attribute.

Original pull request: #180.

Subject: [PATCH 0623/2145] DATAJDBC-234 - Fixes the default query naming and
 polishing.

The default name now does include the name of the domain class.
The default name now is no longer used when no query with the name specified in the `@Query` annotation is found.

Simplified the unit tests by extracting common functionality and improving naming.
Simplified test configuration.

Original pull request: #180.

+=== Named Queries
+
+If no query is given in an annotation as described in the previous section Spring Data JDBC will try to locate a named query.
+There are two ways how the name of the query can be determined.
+The default is to take the _domain class_ of the query, i.e. the aggregate root of the repository, take its simple name and append the name of the method separated by a `.`.
+Alternatively the `@Query` annotation has a `name` attribute which can be used to specify the name of a query to be looked up.
+
+Named queries are expected to be provided in the property file `META-INF/jdbc-named-queries.properties` on the classpath.
+
+The location of that file may be changed by setting a value to `@EnableJdbcRepositories.namedQueriesLocation`.

We now support interface projections when using as(Class) through ProjectionFactory. Simple, type-less queries (execute, select from table) are backed by Map implementations and require the projection type to return a similar type than the expected value. Simple types (such as numeric types) are converted between the backing result and the projection. Conversion of complex types requires a source with type information such as a typed select (select().from(Person.class).as(PersonProjection.class)) to apply registered converters on property-level.

 `Mono` emits a `IncorrectResultSizeDataAccessException` if the query yields more than a single result.

+TIP: You can directly apply <<projections,Projections>> to result documents by providing the target type via `as(Class<?>)`.
+
 You can consume Query results in three ways:
 
 * Through object mapping (for example, `as(Class<T>)`) by using Spring Data's mapping-metadata.
-* As `Map<String, Object>` where column names are mapped to their value. Column names are looked up in a case-insensitive way.
+* As `Map<String, Object>` where column names are mapped to their value.
+Column names are looked up in a case-insensitive way.
 * By supplying a mapping `BiFunction` for direct access to R2DBC `Row` and `RowMetadata`.
 
 You can switch between retrieving a single entity and retrieving multiple entities through the following terminating methods:

Subject: [PATCH 0659/2145] DATAJDBC-386 - Introduce quoting for all database
 identifier.

All database identifiers, i.e. table names, column names and so on, now get quoted.
For most databases this means they get enclosed with double quotes.
For some databases this makes the the identifiers case sensitive.
In order to minimize the impact we convert identifiers their default letter casing.
This should be upper case according to the SQL standard but isn't for some databases.

The exact behavior regarding quoting and default letter casing gets controlled by a database specific `Dialect`.

Future changes will make the quoting of annotated columns and the default quoting behavior configurable.

Original pull request: #182.

Subject: [PATCH 0660/2145] DATAJDBC-386 - Refactor SqlIdentifier.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix bind marker rendering for delete by Id.

SqlIdentifier provides now a transform(…) method to transform its content instead of exposing prefix(…) and suffix(…) methods. Composite identifiers are created through SqlIdentifier.from(…) instead of exposing a concat(…) method.

We also now apply identifier normalization only to derived identifiers instead of applying normalization to annotated column and table names. This change requires references to derived field names to honor the appropriate letter casing.

Identifier quotation can be disabled globally, via RelationalMappingContext.setForceQuote(false).

Move SqlIdentifier to relational.core.sql package.

From 36b419e712fbb792c0396a859f72099fafb21adf Mon Sep 17 00:00:00 2001
From: Jens Schauder <jschauder@pivotal.io>
Date: Fri, 10 Jan 2020 09:09:46 +0100
Subject: [PATCH 0661/2145] DATAJDBC-386 - Polishing.

Tests that used the `@Column` annotation to map multiple properties to a single database column failed.
Mapping multiple values to one column is possible to allow for entities inside an aggregate to have the id of the aggregate as ID or as part of the ID.

The reason for the test failures was that columns get referred to by different ways:
Once per DerivedSqlIdentifier (i.e. with normalized spelling).
And Once per `@Column` annotation.

SqlIdentifier from an `@Column` annotation have always the same spelling, while the normalized version depends on the `Dialect`.

In order to make the tests work for all databases all references to the column in question had to get a `@Column` annotation.
This in turn required the create scripts to also use quoting when the normal case of the database did not match the case chosen in the annotation.

Finally there were some tests that used hand coded SQL which now uses `SqlIdentifier` and an injected `Dialect` to arrive at the correct SQL syntax.

Removed a couple of `@Ignore` annotations that got left in the code.

Original pull request: #182.

Subject: [PATCH 0662/2145] #291 - Adapt to SqlIdentifier changes in Spring
 Data Relational.

We now use SqlIdentifier to encapsulate the table and column name across the API. The fluent DatabaseClient API accepts the table name and select column projections as SqlIdentifier. The Criteria API remains String-based as names for Query and Update objects may reference either column names or property names.

QueryMapper and UpdateMapper require now a R2DBC dialect object to be constructed. R2dbcMappingContext is configured in a way to not require quoting to preserve backwards compatibility.

Subject: [PATCH 0666/2145] DATAJDBC-464 - Convert parameters.

Parameters now get converted to a suitable type supported by JDBC.

In order to support this the logic of finding the "right" type got moved from `BasicRelationalPersistentProperty` to `JdbcCompatibleTypes`.

Original pull request: #186.

Subject: [PATCH 0668/2145] DATAJDBC-464 - Move
 RelationalPersistentProperty.getColumnType() and getSqlType() to
 JdbcConverter.

RelationalPersistentProperty.getColumnType() and getSqlType() are no longer members of RelationalPersistentProperty but part of the JdbcConverter. Both methods have a strong affinity to JDBC-specifics and belong rather into the conversion strategy and not into mapping-metadata.

Subject: [PATCH 0669/2145] DATAJDBC-464 - No longer require MappingContext to
 create BasicRelationalPersistentProperty.

We now no longer require MappingContext to create BasicRelationalPersistentProperty and BasicJdbcPersistentProperty.
We require only the NamingStrategy so we're just passing that one instead of the entire context.

Original pull request: #186.

Subject: [PATCH 0674/2145] DATAJDBC-484 - Fixes a JDK dependent test failure.

Beginning from JDK 10 `Instant` uses nanosecond precision which doesn't make it through the database.
This caused the test to fail.
This fix fixes only the test by making the assertion more lenient.
Actually storing and retrieving nanosecond precision time values is a separate issue.

Also reduced logging in tests again.

Subject: [PATCH 0675/2145] DATAJDBC-479 - Use SqlIdentifier in SQL AST.

We now use SqlIdentifier to encapsulate names and aliases of tables, columns and functions.

We now use proper delegation to ConditionVisitor to render a JOIN condition.
Previously, we used toString() of Condition segments which rendered an approximation of the condition.
ConditionVisitor applies RenderContext settings that consider identifier quoting and normalization strategies.

From: Jens Schauder <jschauder@pivotal.io>
Date: Tue, 11 Feb 2020 11:02:55 +0100
Subject: [PATCH 0676/2145] DATAJDBC-479 - Polishing.

Fixes compiler error from rebase rebase.
Removes IdentifierProcessingAdapter since it wasn't used anymore
Merged UnquotedDialect with NonQuotingDialect since both served the same purpose of a simple Dialect for testing.
Formatting.

Original pull request: #187.

Subject: [PATCH 0677/2145] #220 - Introduce R2dbcEntityTemplate.

We now provide a Template API that exposes entity-centric methods. It complements DatabaseClient's simple object mapper methods.

Original pull request: #287.

Subject: [PATCH 0680/2145] #220 - Refactor StatementMapper.

Use limit/offset instead of Page and accept Expression objects to declare a select list. Use SqlIdentifier in Update, Query, Criteria and fluent API.

Original pull request: #287.

+=== Entity State Detection Strategies
+
+The following table describes the strategies that Spring Data R2DBC offers for detecting whether an entity is new:
+
+.Options for detection whether an entity is new in Spring Data R2DBC
+[options = "autowidth"]
+|===============
+|Id-Property inspection (the default)   |By default, the `save()` method inspects the identifier property of the given entity.
+If the identifier property is `null`, then the entity is assumed to be new. Otherwise, it is assumed exist in the datbase.
+|Implementing `Persistable`             |If an entity implements `Persistable`, Spring Data R2DBC delegates the new detection to the `isNew(…)` method of the entity.
+See the link:$$https://docs.spring.io/spring-data/data-commons/docs/current/api/index.html?org/springframework/data/domain/Persistable.html$$[Javadoc] for details.
+|Implementing `EntityInformation`       |You can customize the `EntityInformation` abstraction used in `SimpleR2dbcRepository`  by creating a subclass of `R2dbcRepositoryFactory` and overriding `getEntityInformation(…)`.
+You then have to register the custom implementation of `R2dbcRepositoryFactory` as a Spring bean.
+Note that this should rarely be necessary. See the link:{spring-data-r2dbc-javadoc}/org/springframework/data/r2dbc/repository/support/R2dbcRepositoryFactory.html[Javadoc] for details.
+|===============
+
+[[r2dbc.entity-persistence.id-generation]]
+=== ID Generation
+
+Spring Data R2DBC uses the ID to identify entities.
+The ID of an entity must be annotated with Spring Data's https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
+
+When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
+
+One important constraint is that, after saving an entity, the entity must not be new anymore.
+Note that whether an entity is new is part of the entity's state.
+With auto-increment columns, this happens automatically, because the ID gets set by Spring Data with the value from the ID column.

Subject: [PATCH 0702/2145] #310 - Fix bind marker reuse when expanding
 collection arguments using named parameters.

We now correctly reuse bind markers for named parameter substitution when using collection arguments to create dynamic argument lists. Previously, we allocated a new bind marker for each item in the collection which left the parameters intended for reuse unbound.

Subject: [PATCH 0704/2145] #164 - Support @Query definitions with SpEL
 expressions.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We now support SpEL expressions in string-based queries to bind parameters for more dynamic queries. SpEL expressions are enclosed in :#{…} and rendered as synthetic named parameter so their values are substituted with bound parameters to avoid SQL injection attach vectors.

interface PersonRepository extends Repository<Person, String> {

	@Query("SELECT * FROM person WHERE lastname = :#{'hello'}")
	Mono<Person> findHello();

	@Query("SELECT * FROM person WHERE lastname = :#{[0]} and firstname = :firstname")
	Mono<Person> findByLastnameAndFirstname(@Param("value") String value, @Param("firstname") String firstname);

	@Query("SELECT * FROM person WHERE lastname = :#{#person.name}")
	Mono<Person> findByExample(@Param("person") Person person);
}

+=== Queries with SpEL Expressions
+
+Query string definitions can be used together with SpEL expressions to create dynamic queries at runtime.
+SpEL expressions can provide predicate values which are evaluated right before executing the query.
+
+Expressions expose method arguments through an array that contains all the arguments.
+The following query uses `[0]`
+to declare the predicate value for `lastname` (which is equivalent to the `:lastname` parameter binding):
+
+[source,java]
+----
+public interface PersonRepository extends ReactiveCrudRepository<Person, String> {
+
+  @Query("SELECT * FROM person WHERE lastname = :#{[0]} }")
+  List<Person> findByQueryWithExpression(String lastname);
+}
+----
+
+SpEL in query strings can be a powerful way to enhance queries.
+However, they can also accept a broad range of unwanted arguments.
+You should make sure to sanitize strings before passing them to the query to avoid unwanted changes to your query.
+
+Expression support is extensible through the Query SPI: `org.springframework.data.spel.spi.EvaluationContextExtension`.
+The Query SPI can contribute properties and functions and can customize the root object.
+Extensions are retrieved from the application context at the time of SpEL evaluation when the query is built.
+
+TIP: When using SpEL expressions in combination with plain parameters, use named parameter notation instead of native bind markers to ensure a proper binding order.

Subject: [PATCH 0705/2145] #311 - Use R2dbcMappingContext in
 AbstractR2dbcConfiguration instead of RelationalMappingContext.

We use now a more concrete type in the configuration to avoid clashes when Spring Data JDBC is on the class path.

Subject: [PATCH 0706/2145] DATAJDBC-488 - Avoid deadlocks by first accessing
 the root entity.

The previous process of deleting referencing entities, updating the root and then inserting referencing entities hat the potential of causing deadlocks.
When one process didn't obtain a lock on delete because there wasn't anything to delete root and referencing entities got locks in opposite order, which is a classical cause for deadlocks.

Original pull request: #191.

Subject: [PATCH 0708/2145] DATAJDBC-491 - Correctly combine schema- and table
 name.

We no correctly combine schema and table name using separate SqlIdentifier objects instead of leaving the schema name as part of the table name. Previously, the concatenated name failed to resolve with quoted identifiers.

Subject: [PATCH 0718/2145] #289 - Add support for Criteria composition.

We now support composition of Criteria objects to create a Criteria from one or more top-level criteria and to compose nested AND/OR Criteria objects:

Criteria.where("name").is("Foo")).and(Criteria.where("name").is("Bar").or("age")
				.lessThan(49).or(Criteria.where("name").not("Bar").and("age").greaterThan(49))

 DatabaseClient.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We now accept StatementFilterFunction and ExecuteFunction via DatabaseClient to filter Statement execution. StatementFilterFunctions can be used to pre-process the statement or post-process Result objects.

databaseClient.execute(…)
		.filter((s, next) -> next.execute(s.returnGeneratedValues("my_id")))
		.filter((s, next) -> next.execute(s.fetchSize(25)))

databaseClient.execute(…)
		.filter(s -> s.returnGeneratedValues("my_id"))
		.filter(s -> s.fetchSize(25))

Subject: [PATCH 0739/2145] DATAJDBC-454 - Adds generics to events.

Events now have a type parameter for the type of aggregate root they relate to.
In order to utilize this an react to only events relating to a specific type of entity `AbstractRelationalEventListener` was added.

Original pull request: #199.

Subject: [PATCH 0748/2145] DATAJDBC-455 - Adds dynamic Dialect detection.

So far the user had to specify an `Dialect` themselves if they wanted to use anything but HSQLDB.
We now identify the supported databases and pick the appropriate `Dialect`.

Vendors who want to offer support for their database may provide an implementation of `JdbcDialectProvider` and register it using a  file under the key `org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider`.

+<2> `AbstractJdbcConfiguration` provides various default beans required by Spring Data JDBC
+<3> Creates a `DataSource` connecting to a database. This is required by the following two bean methods.
+<4> Creates the `NamedParameterJdbcOperations` used by Spring Data JDBC to access the database.
+<5> Spring Data JDBC utilizes the transaction management provided by Spring JDBC.
 ====
 
 The configuration class in the preceding example sets up an embedded HSQL database by using the `EmbeddedDatabaseBuilder` API of `spring-jdbc`.
-We activate Spring Data JDBC repositories by using the `@EnableJdbcRepositories`.
+The `DataSource` is then used to set up `NamedParameterJdbcOperations` and a `TransactionManager.
+We finally activate Spring Data JDBC repositories by using the `@EnableJdbcRepositories`.
 If no base package is configured, it uses the package in which the configuration class resides.
+Extending `AbstractJdbcConfiguration` ensures various beans get registered.
+Overwriting its methods can be used to customize the setup (see below).
+
+This configuration can be further simplified by using Spring Boot.
+With Spring Boot a `DataSource` is sufficient once the starter `spring-boot-starter-data-jdbc` is included in the dependencies.
+Everything else is done by Spring Boot.
+
+There are a couple of things one might want to customize in this setup
+
+You can register custom conversions which will be used when writing to or reading from the database by overwriting `jdbcCustomConversions` as demonstrated in the following example:
+====
+[source, java]
+----
+    @Overwrite
+	@Bean
+	public JdbcCustomConversions jdbcCustomConversions() {
+		return new JdbcCustomConversions(new JdbcCustomConversions(Arrays.asList(BooleanToStringConverter.INSTANCE, StringToBooleanConverter.INSTANCE)));
+	}
+
+
+	@WritingConverter
+	enum BooleanToStringConverter implements Converter<Boolean, String> {
+
+		INSTANCE;
+
+		@Override
+		public String convert(Boolean source) {
+			return source != null && source ? "T" : "F";
+		}
+	}
+
+	@ReadingConverter
+	enum StringToBooleanConverter implements Converter<String, Boolean> {
+
+		INSTANCE;
+
+		@Override
+		public Boolean convert(String source) {
+			return source != null && source.equalsIgnoreCase("T") ? Boolean.TRUE : Boolean.FALSE;
+		}
+	}
+----
+====
+
+Spring Data JDBC uses implementations of the interface `Dialect` to encapsulate behavior that is specific to a database or its JDBC driver.
+By default the `AbstractJdbcConfiguration` tries to determine the database in use an register the correct `Dialect`.
+This behavior can be changed by overwriting `dialect(NamedParameterJdbcOperations)`.
+
+Database vendors may provide an implementation of `JdbcDialectProvider` along with a matching entry in the `META-INF/spring-factories` file registering it for the key `org.springframework.data.jdbc.repository.config.JdbcDialectResolver$JdbcDialectProvider`.
+The `JdbcDialectProvider` should detect the database and provide an appropriate `Dialect` implementation for it.

Subject: [PATCH 0751/2145] DATAJDBC-455 - Polishing.

Rename Dialect bean to jdbcDialect to avoid generic bean names. Require JdbcOperations in DialectResolver. Rename JdbcDialectResolver to DialectResolver for consistent naming with R2DBC the underlying type is a Dialect.

Tweak Javadoc and extend documentation with custom conversions include from Spring Data Commons. Extract MySQL identifier processing defaults into constant.

+    }
+}
+----
+
+There are a couple of things to notice here: `Boolean` and `String` are both simple types hence Spring Data requires a hint in which direction this converter should apply (reading or writing).

-This behavior can be changed by overwriting `dialect(NamedParameterJdbcOperations)`.
+This behavior can be changed by overwriting `jdbcDialect(NamedParameterJdbcOperations)`.
 
-Database vendors may provide an implementation of `JdbcDialectProvider` along with a matching entry in the `META-INF/spring-factories` file registering it for the key `org.springframework.data.jdbc.repository.config.JdbcDialectResolver$JdbcDialectProvider`.
-The `JdbcDialectProvider` should detect the database and provide an appropriate `Dialect` implementation for it.
+TIP: Dialects are resolved by [`JdbcDialectResolver`] from `JdbcOperations`, typically by inspecting `Connection`.
++ You can let Spring auto-discover your `Dialect` by registering a class that implements `org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider` through `META-INF/spring.factories`.
+`DialectResolver` discovers dialect provider implementations from the class path using Spring's `SpringFactoriesLoader`.

Subject: [PATCH 0759/2145] DATAJDBC-514 - Add support for Between and Not Like
 to Criteria API and SQL generation.

We now support Conditions.between, notBetween, and notLike as additional criteria conditions and support case-insensitive comparisons.
For LIKE escaping we pick up the Escaper configured at Dialect level. The newly introduced ValueFunction allows string transformation before computing a value by applying the Escaper to the raw value. Escaping is required for StartingWith, Contains and EndsWith PartTree operations.

Subject: [PATCH 0760/2145] #282 - Add support for query derivation.

We now support query derivation for R2DBC repositories:

interface ReactivePersonRepository extends ReactiveSortingRepository<Person, String> {

  Flux<Person> findByFirstname(String firstname);

  Flux<Person> findByFirstname(Publisher<String> firstname);

  Mono<Person> findByFirstnameAndLastname(String firstname, String lastname);

  Flux<Person> findFirstByLastnameLike(String pattern);
}

Original pull request: #295.

Subject: [PATCH 0762/2145] #282 - Polishing.

Move query derivation infrastructure to Spring Data Relational. Adapt to newly introduced ValueFunction for deferred value mapping. Use query derivation in integration tests.

Tweak javadoc, add since and author tags, reformat code.

Related ticket: https://jira.spring.io/browse/DATAJDBC-514
Original pull request: #295.

-<1> The `findByLastname` method shows a query for all people with the given last name.
+<1> The method shows a query for all people with the given `lastname`. The query is derived by parsing the method name for constraints that can be concatenated with `And` and `Or`. Thus, the method name results in a query expression of `SELECT … FROM person WHERE firstname = :firstname`.
+<2> The method shows a query for all people with the given `firstname` once the `firstname` is emitted by the given `Publisher`.
+<3> Use `Pageable` to pass offset and sorting parameters to the database.
+<4> Find a single entity for the given criteria. It completes with `IncorrectResultSizeDataAccessException` on non-unique results.
+<5> Unless <4>, the first entity is always emitted even if the query yields more result documents.

Subject: [PATCH 0765/2145] DATAJDBC-453 - DbActions and AggregateChange are
 effectively immutable.

Removed the Interpreter and replaced it with AggregateChangeExecutor and  AggregateChangeExecutionContext.
The latter handles the mutable data like ids and versions.

Date: Mon, 30 Mar 2020 14:07:43 +0200
Subject: [PATCH 0766/2145] DATAJDBC-453 - Polishing.

Remove unused AggregateChangeExecutionContext. Extract MutableAggregateChange interface and use it to encapsulate the implementation class. Expose MutableAggregateChange in entity callbacks where mutation of the MutableAggregateChange is intended.

Fix generics and license headers, tweak Javadoc.

Subject: [PATCH 0768/2145] DATAJDBC-341 - Reworked the changes.

Turns out this was a little more involved than expected.
This modifies the implementation to not use exceptions for flow control.

Properties that get set via setter, wither or field access get not invoked for missing columns.
When properties get referenced in constructors a missing column results in an exception.

As a side effect we now access the `ResultSet` by index.
Depending on how the driver is implemented this might improve the performance a little.

+For converting the query result into entities the same `RowMapper` is used by default as for the queries Spring Data JDBC generates itself.
+The query you provide must match the format the `RowMapper` expects.
+Columns for all properties that are used in the constructor of an entity must be provided.
+Columns for properties that get set via setter, wither or field access are optional.
+Properties that don't have a matching column will not get set.
+The query is used for populating the aggregate root, embedded entities and one to one relationships including arrays of primitive types which get stored and loaded as SQL-array-types.
+For maps, lists, sets and arrays of entities separate queries get generated.
+
 NOTE: Spring fully supports Java 8’s parameter name discovery based on the `-parameters` compiler flag. By using this flag in your build as an alternative to debug information, you can omit the `@Param` annotation for named parameters.
 
 NOTE: Spring Data JDBC supports only named parameters.

 == What's New in Spring Data JDBC 1.1

From c0803ddafef7a4bc4ec070df6581d46c4d59ff4a Mon Sep 17 00:00:00 2001
From: Mark Paluch <mpaluch@pivotal.io>
Date: Tue, 31 Mar 2020 11:45:53 +0200
Subject: [PATCH 0769/2145] DATAJDBC-341 - Polishing.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove SpecialColumnValue in favor of JdbcPropertyValueProvider.hasProperty(…). Rename ResultSetWrapper to ResultSetAccessor. Replace ResultSetAccessor usage in JdbcConverter with ResultSet to avoid visibility issues.

Original pull request: #201.

Subject: [PATCH 0802/2145] #344 - Add support for support distinct derived
 query methods.

We now support distinct derived queries that are useful with projections to retrieve distinct results.

interface UserRepository extends Repository<User, Long> {

  Mono<UserProjection> findDistinctByFirstName(String firstName);

}

interface UserProjection {

  String getFirstName();

}

Original pull request: #346.

Subject: [PATCH 0803/2145] #344 - Polishing.

Consider projection properties as SELECT projection. Refactor distinct() into marker method without accepting a boolean flag. Make distinct field final. Update tests.

Subject: [PATCH 0807/2145] #93 - Polishing.

Formatting.
Added issue to test comments.

Removed the test for presence of the id in case of a potential optimistic locking exception.
A deleted row is also a case of a concurrent modification and therefore should trigger the OptimisticLockingException.

Original pull request: #314.

Subject: [PATCH 0808/2145] DATAJDBC-318 - Adapting DependencyTests.

Without this change we see cyclic dependencies between modules (i.e. subpackages).
The following subpackages had a cycle:

repository.query and repository.query.parser

PartTreeJdbcQuery and JdbcQueryCreator(repository.query from jdbc) depend on PartTree (repository.query.parser)

AbstractQueryCreator (repository.query.parser) depends on ParameterAccessor (repository.query from commons)

This change changes the definition of a module, bundling all the modules above into one module (repository).

Alternative changes that should fix the problem:
1. Move ParameterAccessor to a different (probably new package)
2. Move AbstractQueryCreator to a different (probably new package)
3. org.springframework.data.jdbc.repository.query to e.g. org.springframework.data.jdbc.repository.query.jdbc

Subject: [PATCH 0809/2145] DATAJDBC-318 - Initial support for query
 derivation.

Move JdbcRepositoryQuery into repository.query package. Split JdbcRepositoryQuery into AbstractJdbcQuery and StringBasedJdbcQuery.
Add QueryMapper for mapping of Criteria.
Initial support for query derivation.

Emit events and issue entity callbacks only for default RowMapper.
Custom RowMapper/ResultSetExtractor are in full control of the mapping and can issue events/callbacks themselves.

Update reference documentation.

 Spring Data JDBC supports optimistic locking by means of a numeric attribute that is annotated with

+https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Version.html[`@Version`] on the aggregate root.
 Whenever Spring Data JDBC saves an aggregate with such a version attribute two things happen:
 The update statement for the aggregate root will contain a where clause checking that the version stored in the database is actually unchanged.
 If this isn't the case an `OptimisticLockingFailureException` will be thrown.

 This section offers some specific information about the implementation and use of Spring Data JDBC.
 
+Most of the data access operations you usually trigger on a repository result in a query being run against the databases.
+Defining such a query is a matter of declaring a method on the repository interface, as the following example shows:
+
+.PersonRepository with query methods
+====
+[source,java]
+----
+interface PersonRepository extends PagingAndSortingRepository<Person, String> {
+
+  List<Person> findByFirstname(String firstname);                                   <1>
+
+  List<Person> findByFirstnameOrderByLastname(String firstname, Pageable pageable); <2>
+
+  Person findByFirstnameAndLastname(String firstname, String lastname);             <3>
+
+  Person findFirstByLastname(String lastname);                                      <4>
+
+  @Query("SELECT * FROM person WHERE lastname = :lastname")
+  List<Person> findByLastname(String lastname);                                     <5>
+}
+----
+<1> The method shows a query for all people with the given `lastname`.
+The query is derived by parsing the method name for constraints that can be concatenated with `And` and `Or`.
+Thus, the method name results in a query expression of `SELECT … FROM person WHERE firstname = :firstname`.
+<2> Use `Pageable` to pass offset and sorting parameters to the database.
+<3> Find a single entity for the given criteria.
+It completes with `IncorrectResultSizeDataAccessException` on non-unique results.
+<4> Unless <3>, the first entity is always emitted even if the query yields more result documents.
+<5> The `findByLastname` method shows a query for all people with the given last name.

Subject: [PATCH 0811/2145] DATAJDBC-318 - Extend query method validation.

We now reject criteria predicates for collections, maps and references. The select list selects all columns until DATAJDBC-523 is solved.

Subject: [PATCH 0812/2145] DATAJDBC-318 - Fixed the generation of the select
 list.

The select list must include columns for 1:1 relationships.

The implementation is copied from SqlGenerator and will be unified in the near future.

Original pull request: #209.

Subject: [PATCH 0813/2145] DATAJDBC-524 - Fixed dependency cycles triggered by
 DATAJDBC-318.

Moved Identifier and IdentifierBuilder to ...jdbc.core.convert.
Moved RelationaAuditingCallback to ..mapping.event.

Improved DependencyTests to properly consider "relational" a main module.

Subject: [PATCH 0832/2145] DATAJDBC-257 - Adds DB2 support.

Db2Dialect added in order to support DB2.
Added test configuration files.
Adapted some tests to make them properly work with DB2
QueryAnnotationIntegrationTests converted into an Hsqldb only test since it is next to impossible to make it work across databases since it heavily depends on database and driver specifics.

Removed license acceptance file from the repository in order to not accept a license in the name of someone forking the repository.
For the CI build an appropriate file gets created on the fly.

Subject: [PATCH 0833/2145] DATAJDBC-257 - Polishing.

Move container initialization from static initializer into createDataSource() to not trigger container start when loading the class.
Add TestExecutionListener to ignore tests if the license for a container was not accepted. Add Awaitility to delay test execution until the database is ready so we avoid strange failures due to a delayed container startup.

Fix generics, since tags, author tags. Reformat code.

Original pull request: #213.

Subject: [PATCH 0834/2145] DATAJDBC-493 - Avoids deadlocks by acquiring lock
 on aggregate root table.

Introduces infrastructure to obtain locks and uses them to acquire locks on the table of the aggregate root before deleting references.
Without this lock deletes access non root entities before the aggregate root, which is the opposite order of updates and thus may cause deadlocks.

Original pull request: #196.

Subject: [PATCH 0835/2145] DATAJDBC-493 - Polishing.

Using `execute` instead of `query` since we are not interested in the results.
Refactoring of the concurrency tests.
Make the concurrency tests run with all databases.
Added support for DB2.
Moved AnsiDialect to the main sources so it can be referenced in other Dialects.

Original pull request: #196.

Subject: [PATCH 0841/2145] #363 - Polishing.

Added an integration test and tweaked the conversions to make it succeed.
The converter now does not rely on the driver to do the conversion anymore.

Original pull request: #360.

Subject: [PATCH 0845/2145] #365 - Fix immutable versioned object usage.

We now use the proper object instance when constructing statements for insert/update of versioned entities. Previously, we created a new instance that is associated with the incremented version number but we did not reuse that instance so the version increment remained invisible.

Subject: [PATCH 0859/2145] #207 - Skip converter registrations for JSR-310 to
 java.util.Date.

We now prevent converter registrations that enforce a conversion from JSR-310 types to java.util.Date. R2DBC drivers use natively JSR-310 types and some of them don't implement java.util.Date at all.

Subject: [PATCH 0864/2145] #369 - Fall back to column name in QueryMapper if
 path expression maps into simple type property.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We now fall back to the column name when resolving a property path expression that maps into a simple-typed property. PropertyPath.from(…) fails internally as it attempts to look up a simple type from the MappingContext and this fails for primitive and simple types.

 Spring Data R2DBC reacts to database specifics by inspecting the `ConnectionFactory` and selects the appropriate database dialect accordingly.
-You can configure your own {spring-data-r2dbc-javadoc}/api/org/springframework/data/r2dbc/dialect/R2dbcDialect.html[`R2dbcDialect`] if the driver you use is not yet known to Spring Data R2DBC.
+You need to configure your own {spring-data-r2dbc-javadoc}/api/org/springframework/data/r2dbc/dialect/R2dbcDialect.html[`R2dbcDialect`] if the driver you use is not yet known to Spring Data R2DBC.
 
 TIP: Dialects are resolved by {spring-data-r2dbc-javadoc}/org/springframework/data/r2dbc/dialect/DialectResolver.html[`DialectResolver`] from a `ConnectionFactory`, typically by inspecting `ConnectionFactoryMetadata`.

Subject: [PATCH 0870/2145] DATAJDBC-547 - Polishing.

Let SqlIdentifier implement Streamable<SqlIdentifier> to allow iteration of composed identifiers.
Adapt dialect to iteration changes.

Rewrite simple if blocks to using ternary operators.

MIME-Version: 1.0

Using Criteria.from(…) with multiple Criteria objects now uses properly AND combination along with group nesting to render a correct criteria. Previously, the INITIAL combinator in groups caused a mapping exception.

 = Preface
 
-Spring Data JDBC offers a repository abstraction based on JDBC.
+The Spring Data JDBC project applies core Spring concepts to the development of solutions that use JDBC databases aligned with <<jdbc.domain-driven-design,Domain-driven design principles>>.
+We provide a "`template`" as a high-level abstraction for storing and querying aggregates.
+
+This document is the reference guide for Spring Data JDBC Support.
+It explains the concepts and semantics and syntax..
+
+This section provides some basic introduction.
+The rest of the document refers only to Spring Data JDBC features and assumes the user is familiar with SQL and Spring concepts.
+
+[[get-started:first-steps:spring]]
+== Learning Spring
+
+Spring Data uses Spring framework's https://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/core.html[core] functionality, including:
+
+* https://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/core.html#beans[IoC] container
+* https://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/core.html#validation[type conversion system]
+* https://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/core.html#expressions[expression language]
+* https://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/integration.html#jmx[JMX integration]
+* https://docs.spring.io/spring/docs/{springVersion}/spring-framework-reference/data-access.html#dao-exceptions[DAO exception hierarchy].
+
+While you need not know the Spring APIs, understanding the concepts behind them is important.
+At a minimum, the idea behind Inversion of Control (IoC) should be familiar, and you should be familiar with whatever IoC container you choose to use.
+
+The core functionality of the JDBC Aggregate support can be used directly, with no need to invoke the IoC services of the Spring Container.
+This is much like `JdbcTemplate`, which can be used "'standalone'" without any other services of the Spring container.
+To leverage all the features of Spring Data JDBC, such as the repository support, you need to configure some parts of the library to use Spring.
+
+To learn more about Spring, you can refer to the comprehensive documentation that explains the Spring Framework in detail.
+There are a lot of articles, blog entries, and books on the subject.
+See the Spring framework https://spring.io/docs[home page] for more information.
+
+[[requirements]]

+
+The Spring Data JDBC binaries require JDK level 8.0 and above and https://spring.io/docs[Spring Framework] {springVersion} and above.

+TIP: Dialects are resolved by `JdbcDialectResolver` from `JdbcOperations`, typically by inspecting `Connection`.
 You can let Spring auto-discover your `Dialect` by registering a class that implements `org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider` through `META-INF/spring.factories`.
 `DialectResolver` discovers dialect provider implementations from the class path using Spring's `SpringFactoriesLoader`.
 
+If you use a database for which no dialect is available, then your application won’t startup. In that case, you’ll have to ask your vendor to provide a `Dialect` implementation. Alternatively, you can:
+
+1. Implement your own `Dialect`.
+2. Implement a `JdbcDialectProvider` returning the `Dialect`.

 This behavior can be changed by overwriting `jdbcDialect(NamedParameterJdbcOperations)`.
 
-TIP: Dialects are resolved by `JdbcDialectResolver` from `JdbcOperations`, typically by inspecting `Connection`.
-You can let Spring auto-discover your `Dialect` by registering a class that implements `org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider` through `META-INF/spring.factories`.
-`DialectResolver` discovers dialect provider implementations from the class path using Spring's `SpringFactoriesLoader`.

 If you use a database for which no dialect is available, then your application won’t startup. In that case, you’ll have to ask your vendor to provide a `Dialect` implementation. Alternatively, you can:

Subject: [PATCH 0900/2145] DATAJDBC-559 - Upgrading the MariaDB JDBC driver.

This changes the behavior of the JDBC driver from always returning `MySQL` for product name to a more involved logic which might result in it returning  `MariaDB`.

Subject: [PATCH 0905/2145] DATAJDBC-256 - Run integration tests with Oracle.

An Oracle database is started in Docker using Testcontainers.
Tests that don't work yet are skipped using the TestDatabaseFeatures which allows central control, which database supports which feature.

A suitable oracle image is deployed on DockerHub as  "springci/spring-data-oracle-xe-prebuild:18.4.0".
 The official Oracle docker images as described here https://github.com/oracle/docker-images/blob/master/OracleDatabase/SingleInstance/README.md are not suitable since it needs about 15min to start and also TestContainers seems to break it by trying to us it to early.
 The referenced image was created based on these instructions: https://github.com/oracle/docker-images/tree/master/OracleDatabase/SingleInstance/samples/prebuiltdb

The following features don't yet work for Oracle:

* Loading of date like properties.
* Ids with custom names.
* Array support.
* Boolean properties.
* BigDecimals and BigInteger is limited to what fits into Oracles NUMBER data type.
* Entities that use a join during load time, i.e. with a one to one relationship.

Subject: [PATCH 0914/2145] DATAJDBC-573 - Fixes the wait strategy for Oracle
 data sources.

Oracle integration tests where failing when the docker container was freshly started,
as it happens every time on CI.

The reason was mainly a misuse of Awaitility.ignoreException(Class) which only ignores exception of exactly the class provided, not of subtypes.

Apart from fixing this for Oracle the complete logic for verifying the connection was moved to DataSourceConfiguration so other database use it as well in a consistent manner.

Subject: [PATCH 0918/2145] DATAJDBC-576 - Control test execution with missing
 licence via profile.

Running all tests with

```
./mvnw clean install -Pall-dbs
```

or similar now requires an appropriate `container-license-acceptance.txt` to be on the classpath.

In order to ignore the tests that require an explicit license acceptance one may add the maven profile `ignore-missing-license` like so

```
./mvnw clean install -Pall-dbs,ignore-missing-license
```

+= Store specific EntityCallbacks
+
+Spring Data R2DBC uses the `EntityCallback` API and reacts on the following callbacks.
+
+.Supported Entity Callbacks
+[%header,cols="4"]
+|===
+| Callback
+| Method
+| Description
+| Order
+
+| BeforeConvertCallback
+| `onBeforeConvert(T entity, SqlIdentifier table)`
+| Invoked before a domain object is converted to `OutboundRow`.
+| `Ordered.LOWEST_PRECEDENCE`
+
+| AfterConvertCallback
+| `onAfterConvert(T entity, SqlIdentifier table)`
+| Invoked after a domain object is loaded. +
+Can modify the domain object after reading it from a row.
+| `Ordered.LOWEST_PRECEDENCE`
+
+| BeforeSaveCallback
+| `onBeforeSave(T entity, OutboundRow row, SqlIdentifier table)`
+| Invoked before a domain object is saved. +
+Can modify the target, to be persisted, `OutboundRow` containing all mapped entity information.
+| `Ordered.LOWEST_PRECEDENCE`
+
+| AfterSaveCallback
+| `onAfterSave(T entity, OutboundRow row, SqlIdentifier table)`
+| Invoked before a domain object is saved. +
+Can modify the domain object, to be returned after save, `OutboundRow` containing all mapped entity information.

Removed the language of oppression and violence and replaced it with more neutral language.

Note that problematic words in the code have to remain in the docs until the code changes.

 reference in EnableR2dbcRepositories.

We now accept a bean reference to R2dbcEntityOperations so that a single application can scan for repositories that use different dialects/database systems.

+[[r2dbc.multiple-databases]]
+=== Working with multiple Databases
+
+When working with multiple, potentially different databases, your application will require a different approach to configuration.
+The provided `AbstractR2dbcConfiguration` support class assumes a single `ConnectionFactory` from which the `Dialect` gets derived.
+That being said, you need to define a few beans yourself to configure Spring Data R2DBC to work with multiple databases.
+
+R2DBC repositories require either a `DatabaseClient` and `ReactiveDataAccessStrategy` or `R2dbcEntityOperations` to implement repositories.
+A simple configuration to scan for repositories without using `AbstractR2dbcConfiguration` looks like:
+
+[source,java]
+----
+@Configuration
+@EnableR2dbcRepositories(basePackages = "com.acme.mysql", entityOperationsRef = "mysqlR2dbcEntityOperations")
+static class MySQLConfiguration {
+
+    @Bean
+    @Qualifier("mysql")
+    public ConnectionFactory mysqlConnectionFactory() {
+        return …;
+    }
+
+    @Bean
+    public R2dbcEntityOperations mysqlR2dbcEntityOperations(@Qualifier("mysql") ConnectionFactory connectionFactory) {
+
+        DefaultReactiveDataAccessStrategy strategy = new DefaultReactiveDataAccessStrategy(MySqlDialect.INSTANCE);
+        DatabaseClient databaseClient = DatabaseClient.builder()
+                .connectionFactory(connectionFactory)
+                .dataAccessStrategy(strategy)
+                .build();
+
+        return new R2dbcEntityTemplate(databaseClient, strategy);
+    }
+}
+----
+
+Note that `@EnableR2dbcRepositories` allows configuration either through `databaseClientRef` or `entityOperationsRef`.
+Using various `DatabaseClient` beans is useful when connecting to multiple databases of the same type.
+When using different database systems that differ in their dialect, use `@EnableR2dbcRepositories`(entityOperationsRef = …)` instead.

Subject: [PATCH 0934/2145] #407 - Add ReactiveSortingRepository support.

Implements ReactiveSortingRepository on SimpleR2dbcRepository. Also changed R2dbcRepository to extend ReactiveSortingRepository and updated comments where it felt reasonable.

Added a single unit test for the new method, and changed the base interface of LegoSetRepository in AbstractR2dbcRepositoryIntegrationTests for integration testing purposes.

Clarify documentation on reactive repository base interfaces

Adds some language calling out ReactiveSortingRepository and fixes consistency between related examples.

Original pull request: #408.

Subject: [PATCH 0936/2145] #281 - Add support for auditing.

We now provide auditing support that can be enabled through EnableR2dbcAuditing.

@Configuration
@EnableR2dbcAuditing
class Config {

  @Bean
  public ReactiveAuditorAware<String> myAuditorProvider() {
      return new AuditorAwareImpl();
  }
}

+== General Auditing Configuration for R2DBC
+
+Since Spring Data R2DBC 1.2, auditing can be enabled by annotating a configuration class with the `@EnableR2dbcAuditing` annotation, as the following example shows:
+
+.Activating auditing using JavaConfig
+====
+[source,java]
+----
+@Configuration
+@EnableR2dbcAuditing
+class Config {
+
+  @Bean
+  public ReactiveAuditorAware<AuditableUser> myAuditorProvider() {
+      return new AuditorAwareImpl();
+  }
+}
+----
+====
+
+If you expose a bean of type `ReactiveAuditorAware` to the `ApplicationContext`, the auditing infrastructure picks it up automatically and uses it to determine the current user to be set on domain types.
+If you have multiple implementations registered in the `ApplicationContext`, you can select the one to be used by explicitly setting the `auditorAwareRef` attribute of `@EnableR2dbcAuditing`.

Subject: [PATCH 0943/2145] #421 - Handle modifying query methods returning
 kotlin.Unit.

Added check for kotlin.Unit to AbstractR2dbcQuery#getExecutionToWrap. This case is essentially equivalent to a return type of Void, but the singleton Unit instance needs to be returned instead of discarding the result entirely.

It was also necessary to add a check to R2dbcQueryMethod#getEntityInformation, as otherwise a PersistentEntity is created for Unit, which leads to a new instance being created via reflection down the pipeline (which is probably not a thing that should happen).

Original pull request: #422.

+=== Optimistic Locking
+
+The `@Version` annotation provides syntax similar to that of JPA in the context of R2DBC and makes sure updates are only applied to documents with a matching version.
+Therefore, the actual value of the version property is added to the update query in such a way that the update does not have any effect if another operation altered the document in the meantime. In that case, an `OptimisticLockingFailureException` is thrown.
+The following example shows these features:

+[appendix]
+= Migration Guide
+
+The following sections explain how to migrate to a newer version of Spring Data R2DBC.
+
+[[upgrading.1.1-1.2]]
+== Upgrading from 1.1.x to 1.2.x
+
+Spring Data R2DBC was developed with the intent to evaluate how well R2DBC can integrate with Spring applications.
+One of the main aspects was to move core support into Spring Framework once R2DBC support has proven useful.
+Spring Framework 5.3 ships with a new module: Spring R2DBC.
+
+`spring-r2dbc` ships core R2DBC functionality (a slim variant of `DatabaseClient`, Transaction Manager, Connection Factory initialization, Exception translation) that was initially provided by Spring Data R2DBC. The 1.2.0 release aligns with what's provided in Spring R2DBC by making several changes outlined in the following sections.
+
+[[upgrading.1.1-1.2.deprecation]]
+=== Deprecations
+
+* Deprecation of `o.s.d.r2dbc.core.DatabaseClient` and its support classes `ConnectionAccessor`, `FetchSpec`, `SqlProvider` and a few more.
+Named parameter support classes such as `NamedParameterExpander` are encapsulated by Spring R2DBC's `DatabaseClient` implementation hence we're not providing replacements as this was internal API in the first place.
+Use `o.s.r2dbc.core.DatabaseClient` and their Spring R2DBC replacements available from `org.springframework.r2dbc.core`.
+Entity-based methods (`select`/`insert`/`update`/`delete`) methods are available through `R2dbcEntityTemplate` which was introduced with version 1.1.
+* Deprecation of `o.s.d.r2dbc.connectionfactory`, `o.s.d.r2dbc.connectionfactory.init`, and `o.s.d.r2dbc.connectionfactory.lookup` packages.
+Use Spring R2DBC's variant which you can find at `o.s.r2dbc.connection`.
+* Deprecation of `o.s.d.r2dbc.convert.ColumnMapRowMapper`.
+Use `o.s.r2dbc.core.ColumnMapRowMapper` instead.
+* Deprecation of binding support classes `o.s.d.r2dbc.dialect.Bindings`, `BindMarker`, `BindMarkers`, `BindMarkersFactory` and related types.
+Use replacements from `org.springframework.r2dbc.core.binding`.
+* Deprecation of `BadSqlGrammarException`, `UncategorizedR2dbcException` and exception translation at `o.s.d.r2dbc.support`.
+Spring R2DBC provides a slim exception translation variant without an SPI for now available through `o.s.r2dbc.connection.ConnectionFactoryUtils#convertR2dbcException`.
+
+[[upgrading.1.1-1.2.replacements]]
+=== Usage of replacements provided by Spring R2DBC
+
+To ease migration, several deprecated types are now subtypes of their replacements provided by Spring R2DBC. Spring Data R2DBC has changes several methods or introduced new methods accepting Spring R2DBC types.
+Specifically the following classes are affected:
+
+* `R2dbcEntityTemplate`
+* `R2dbcDialect`
+* Types in `org.springframework.data.r2dbc.query`
+
+We recommend that you review your imports if you work with these types directly.
+
+[[upgrading.1.1-1.2.dependencies]]
+=== Dependency Changes
+
+To make use of Spring R2DBC, make sure to include the following dependency:
+
+* `org.springframework:spring-r2dbc`

 `spring-r2dbc` ships core R2DBC functionality (a slim variant of `DatabaseClient`, Transaction Manager, Connection Factory initialization, Exception translation) that was initially provided by Spring Data R2DBC. The 1.2.0 release aligns with what's provided in Spring R2DBC by making several changes outlined in the following sections.
 
+Spring R2DBC's `DatabaseClient` is a more lightweight implementation that encapsulates a pure SQL-oriented interface.
+You will notice that the method to run SQL statements changed from `DatabaseClient.execute(…)` to `DatabaseClient.sql(…)`.
+The fluent API for CRUD operations has moved into `R2dbcEntityTemplate`.

Subject: [PATCH 0955/2145] #402 - Exclude id property using initial value when
 inserting objects.

We now exclude Id properties from being used in the INSERT field list if the Id value is zero and of a primitive type or if the value is null using a numeric wrapper type.

 When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
 
+Spring Data R2DBC does not attempt to insert values of identifier columns when the entity is new and the identifier value defaults to its initial value.
+That is `0` for primitive types and `null` if the identifier property uses a numeric wrapper type such as `Long`.
+
 One important constraint is that, after saving an entity, the entity must not be new anymore.
 Note that whether an entity is new is part of the entity's state.
 With auto-increment columns, this happens automatically, because the ID gets set by Spring Data with the value from the ID column.

Subject: [PATCH 0956/2145] #411 - Introduce EnumWriteSupport for simpler
 pass-thru of enum values.

We now provide EnumWriteSupport as base class for enum write converters that should be written as-is to the driver.

R2dbcCustomConversions can now also be created from a dialect for easier R2dbcCustomConversions creation.

+==== Overriding Enum Mapping with Explicit Converters
+
+Some databases, such as https://github.com/pgjdbc/r2dbc-postgresql#postgres-enum-types[Postgres], can natively write enum values using their database-specific enumerated column type.
+Spring Data converts `Enum` values by default to `String` values for maximum portability.
+To retain the actual enum value, register a `@Writing` converter whose source and target types use the actual enum type to avoid using `Enum.name()` conversion.
+Additionally, you need to configure the enum type on the driver level so that the driver is aware how to represent the enum type.
+
+The following example shows the involved components to read and write `Color` enum values natively:
+
+====
+[source,java]
+----
+enum Color {
+    Grey, Blue
+}
+
+class ColorConverter extends EnumWriteSupport<Color> {
+
+}
+
+
+class Product {
+    @Id long id;
+    Color color;
+
+    // …
+}

Subject: [PATCH 0970/2145] #440 - Create R2dbcEntityTemplate in
 R2dbcRepositoryFactoryBean.

We now create R2dbcEntityTemplate as part of R2dbcRepositoryFactoryBean initialization if the factory bean was configured with DatabaseClient and DataAccessStrategy only. Creating the template in the factory bean allows collecting entity callbacks for repository usage.

Subject: [PATCH 0973/2145] #447 - Deprecate ReactiveDataAccessStrategy.

ReactiveDataAccessStrategy is now deprecated in favor of using StatementMapper, UpdateMapper, and R2dbcConverter directly. The access strategy interface was introduced to allow pluggable access strategies in DatabaseClient. With moving DatabaseClient into Spring Framework, this approach is no longer required.

Subject: [PATCH 0976/2145] #451 - Initialize version for versioned entities
 after BeforeConvert callback.

We now initialize/increment the version of versioned entities (optimistic locking) after running the BeforeConvert callback. BeforeConvert callbacks may contain features such as auditing and if the auditing callback issues a isNew check, then the version would be already populated which leads to the auditing callback considering the entity not new anymore leaving the created date empty.

 INSERT.

We now propagate auto-generated Id values to primitive Id properties if the value in the domain model is zero. This happens in addition to non-primitive values being null to ensure that generated values end up in the domain model.

-== Using `ConnectionFactory`
-
-Spring obtains an R2DBC connection to the database through a `ConnectionFactory`.
-A `ConnectionFactory` is part of the R2DBC specification and is a generalized connection factory.
-It lets a container or a framework hide connection pooling and transaction management issues from the application code.
-As a developer, you need not know details about how to connect to the database.
-That is the responsibility of the administrator who sets up the `ConnectionFactory`.
-You most likely fill both roles as you develop and test code, but you do not necessarily have to know how the production data source is configured.
-
-When you use Spring's R2DBC layer, you can configure your own with a connection pool implementation provided by a third party.
-A popular implementation is R2DBC `Pool`.
-Implementations in the Spring distribution are meant only for testing purposes and do not provide pooling.
-
-To configure a `ConnectionFactory`:
-
-. Obtain a connection with `ConnectionFactory` as you typically obtain an R2DBC `ConnectionFactory`.
-. Provide an R2DBC URL.
-(See the documentation for your driver for the correct value.)
-
-The following example shows how to configure a `ConnectionFactory` in Java:
-
-====
-[source,java,indent=0]
-[subs="verbatim,quotes"]
-----
-	ConnectionFactory factory = ConnectionFactories.get("r2dbc:h2:mem:///test?options=DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE");
-----
-====
-
-[[r2dbc.connections.ConnectionFactoryUtils]]
-== Using `ConnectionFactoryUtils`
-
-The `ConnectionFactoryUtils` class is a convenient and powerful helper class that provides `static` methods to obtain connections from `ConnectionFactory` and close connections (if necessary).
-It supports subscriber ``Context``-bound connections with, for example `ConnectionFactoryTransactionManager`.
-
-[[r2dbc.connections.SmartConnectionFactory]]
-== Implementing `SmartConnectionFactory`
-
-The `SmartConnectionFactory` interface should be implemented by classes that can provide a connection to a relational database.
-It extends the `ConnectionFactory` interface to let classes that use it query whether the connection should be closed after a given operation.
-This usage is efficient when you know that you need to reuse a connection.
-
-
-[[r2dbc.connections.TransactionAwareConnectionFactoryProxy]]
-== Using `TransactionAwareConnectionFactoryProxy`
-
-`TransactionAwareConnectionFactoryProxy` is a proxy for a target `ConnectionFactory`.
-The proxy wraps that target `ConnectionFactory` to add awareness of Spring-managed transactions.
-
-[[r2dbc.connections.ConnectionFactoryTransactionManager]]
-== Using `ConnectionFactoryTransactionManager`
-
-The `ConnectionFactoryTransactionManager` class is a `ReactiveTransactionManager` implementation for single R2DBC datasources.
-It binds an R2DBC connection from the specified data source to the subscriber `Context`, potentially allowing for one subscriber connection for each data source.
-
-Application code is required to retrieve the R2DBC connection through `ConnectionFactoryUtils.getConnection(ConnectionFactory)`, instead of R2DBC's standard `ConnectionFactory.create()`.
-All framework classes (such as `DatabaseClient`) use this strategy implicitly.
-If not used with this transaction manager, the lookup strategy behaves exactly like the common one. Thus, it can be used in any case.
-
-The `ConnectionFactoryTransactionManager` class supports custom isolation levels that get applied to the connection.

-[[r2dbc.datbaseclient]]
-= Introduction to `DatabaseClient`
-
-Spring Data R2DBC includes a reactive, non-blocking `DatabaseClient` for database interaction.
-The client has a functional, fluent API with reactive types for declarative composition.
-`DatabaseClient` encapsulates resource handling (such as opening and closing connections) so that your application code can run SQL queries or call higher-level functionality (such as inserting or selecting data).
-
-NOTE: `DatabaseClient` is a recently developed application component that provides a minimal set of convenience methods that is likely to be extended through time.
-
-NOTE: Once configured, `DatabaseClient` is thread-safe and can be reused across multiple instances.
-
-Another central feature of `DatabaseClient` is the translation of exceptions thrown by R2DBC drivers into Spring's portable Data Access Exception hierarchy. See "`<<r2dbc.exception>>`" for more information.
-
-The next section contains an example of how to work with the `DatabaseClient` in the context of the Spring container.
-
-[[r2dbc.datbaseclient.create]]
-== Creating a `DatabaseClient` Object
-
-The simplest way to create a `DatabaseClient` object is through a static factory method, as follows:
-
-====
-[source,java]
-----
-DatabaseClient.create(ConnectionFactory connectionFactory)
-----
-====
-
-The preceding method creates a `DatabaseClient` with default settings.
-
-You can also obtain a `Builder` instance from `DatabaseClient.builder()`.
-You can customize the client by calling the following methods:
-
-* `….exceptionTranslator(…)`: Supply a specific `R2dbcExceptionTranslator` to customize how R2DBC exceptions are translated into Spring's portable Data Access Exception hierarchy.
-See "`<<r2dbc.exception>>`" for more information.
-* `….dataAccessStrategy(…)`: Set the strategy how SQL queries are generated and how objects are mapped.
-
-Once built, a `DatabaseClient` instance is immutable. However, you can clone it and build a modified copy without affecting the original instance, as the following example shows:
-
-====
-[source,java]
-----
-DatabaseClient client1 = DatabaseClient.builder()
-  .exceptionTranslator(exceptionTranslatorA).build();
-
-DatabaseClient client2 = client1.mutate()
-  .exceptionTranslator(exceptionTranslatorB).build();
-----
-====
-
-== Controlling Database Connections
-
-Spring Data R2DBC obtains a connection to the database through a `ConnectionFactory`.
-A `ConnectionFactory` is part of the R2DBC specification and is a generalized connection factory.
-It lets a container or a framework hide connection pooling and transaction management issues from the application code.
-
-When you use Spring Data R2DBC, you can create a `ConnectionFactory` by using your R2DBC driver.
-`ConnectionFactory` implementations can either return the same connection or different connections or provide connection pooling.
-`DatabaseClient` uses `ConnectionFactory` to create and release connections for each operation without affinity to a particular connection across multiple operations.
-
-Assuming you use H2 as a database, a typical programmatic setup looks something like the following listing:
-
-====
-[source, java]
-----
-H2ConnectionConfiguration config = … <1>
-ConnectionFactory factory = new H2ConnectionFactory(config); <2>
-
-DatabaseClient client = DatabaseClient.create(factory); <3>
-----
-<1> Prepare the database specific configuration (host, port, credentials etc.)
-<2> Create a connection factory using that configuration.
-<3> Create a `DatabaseClient` to use that connection factory.
-====
-
-[[r2dbc.exception]]
-= Exception Translation
-
-The Spring framework provides exception translation for a wide variety of database and mapping technologies.
-The Spring support for R2DBC extends this feature by providing implementations of the `R2dbcExceptionTranslator` interface.
-
-`R2dbcExceptionTranslator` is an interface to be implemented by classes that can translate between `R2dbcException` and Spring’s own `org.springframework.dao.DataAccessException`, which is agnostic in regard to data access strategy.
-Implementations can be generic (for example, using SQLState codes) or proprietary (for example, using Postgres error codes) for greater precision.
-
-`R2dbcExceptionSubclassTranslator` is the implementation of `R2dbcExceptionTranslator` that is used by default.
-It considers R2DBC's categorized exception hierarchy to translate these into Spring's consistent exception hierarchy.
-`R2dbcExceptionSubclassTranslator` uses `SqlStateR2dbcExceptionTranslator` as its fallback if it is not able to translate an exception.
-
-`SqlErrorCodeR2dbcExceptionTranslator` uses specific vendor codes by using Spring JDBC's `SQLErrorCodes`.
-It is more precise than the `SQLState` implementation.
-The error code translations are based on codes held in a JavaBean type class called `SQLErrorCodes`.
-Instances of this class are created and populated by an `SQLErrorCodesFactory`, which (as the name suggests) is a factory for creating `SQLErrorCodes` based on the contents of a configuration file named `sql-error-codes.xml` from Spring's Data Access module.
-This file is populated with vendor codes and based on the `ConnectionFactoryName` taken from `ConnectionFactoryMetadata`.
-The codes for the actual database you are using are used.
-
-The `SqlErrorCodeR2dbcExceptionTranslator` applies matching rules in the following sequence:
-
-. Any custom translation implemented by a subclass.
-Normally, the provided concrete `SqlErrorCodeR2dbcExceptionTranslator` is used, so this rule does not apply.
-It applies only if you have actually provided a subclass implementation.
-. Any custom implementation of the `SQLExceptionTranslator` interface that is provided as the `customSqlExceptionTranslator` property of the `SQLErrorCodes` class.
-. Error code matching is applied.
-. Use a fallback translator.
-
-NOTE: By default, the `SQLErrorCodesFactory` is used to define error codes and custom exception translations.
-They are looked up from a file named `sql-error-codes.xml` (which must be on the classpath), and the matching `SQLErrorCodes` instance is located based on the database name from the database metadata of the database in use.
-`SQLErrorCodesFactory` requires Spring JDBC.
-
-You can extend `SqlErrorCodeR2dbcExceptionTranslator`, as the following example shows:
-
-====
-[source,java]
-----
-public class CustomSqlErrorCodeR2dbcExceptionTranslator extends SqlErrorCodeR2dbcExceptionTranslator {
-
-  protected DataAccessException customTranslate(String task, String sql, R2dbcException r2dbcex) {
-
-    if (sqlex.getErrorCode() == -12345) {
-      return new DeadlockLoserDataAccessException(task, r2dbcex);
-    }
-
-    return null;
-  }
-}
-----
-====
-
-In the preceding example, the specific error code (`-12345`) is translated, while other errors are left to be translated by the default translator implementation.
-To use this custom translator, you must configure `DatabaseClient` through the `exceptionTranslator` builder method, and you must use this `DatabaseClient` for all of the data access processing where this translator is needed.
-The following example shows how you can use this custom translator:
-
-====
-[source,java]
-----
-ConnectionFactory connectionFactory = …;
-
-CustomSqlErrorCodeR2dbcExceptionTranslator exceptionTranslator =

-= Fluent Data Access API
-
-The SQL API of `DatabaseClient` offers you maximum flexibility to run any type of SQL.
-`DatabaseClient` provides a more narrow interface for typical ad-hoc use-cases, such as querying, inserting, updating, and deleting data.
-
-The entry points (`insert()`, `select()`, `update()`, and others) follow a natural naming schema based on the operation to be run.
-Moving on from the entry point, the API is designed to offer only context-dependent methods that lead to a terminating method that creates and runs a SQL statement.
-Spring Data R2DBC uses a `R2dbcDialect` abstraction to determine bind markers, pagination support and the data types natively supported by the underlying driver.
-
-Consider the following simple query:
-
-====
-[source,java]
-----
-Flux<Person> people = databaseClient.select()
-  .from(Person.class)                         <1>
-  .fetch()
-  .all();                                     <2>
-----
-<1> Using `Person` with the `from(…)` method sets the `FROM` table based on mapping metadata.
-It also maps tabular results on `Person` result objects.
-<2> Fetching `all()` rows returns a `Flux<Person>` without limiting results.
-====
-
-The following example declares a more complex query that specifies the table name by name, a `WHERE` condition, and an `ORDER BY` clause:
-
-====
-[source,java]
-----
-Mono<Person> first = databaseClient.select()
-  .from("legoset")                           <1>
-  .matching(where("firstname").is("John")    <2>
-    .and("lastname").in("Doe", "White"))
-  .orderBy(desc("id"))                       <3>
-  .as(Person.class)
-  .fetch()
-  .one();                                    <4>
-----
-<1> Selecting from a table by name returns row results as `Map<String, Object>` with case-insensitive column name matching.
-<2> The issued query declares a `WHERE` condition on `firstname` and `lastname` columns to filter results.
-<3> Results can be ordered by individual column names, resulting in an `ORDER BY` clause.
-<4> Selecting the one result fetches only a single row.
-This way of consuming rows expects the query to return exactly a single result.
-`Mono` emits a `IncorrectResultSizeDataAccessException` if the query yields more than a single result.
-====
-
-TIP: You can directly apply <<projections,Projections>> to result documents by providing the target type via `as(Class<?>)`.
-
-You can consume Query results in three ways:
-
-* Through object mapping (for example, `as(Class<T>)`) by using Spring Data's mapping-metadata.
-* As `Map<String, Object>` where column names are mapped to their value.
-Column names are looked up in a case-insensitive way.
-* By supplying a mapping `BiFunction` for direct access to R2DBC `Row` and `RowMetadata`.
-
-You can switch between retrieving a single entity and retrieving multiple entities through the following terminating methods:
-
-* `first()`: Consume only the first row, returning a `Mono`.
-The returned `Mono` completes without emitting an object if the query returns no results.
-* `one()`: Consume exactly one row, returning a `Mono`.
-The returned `Mono` completes without emitting an object if the query returns no results.
-If the query returns more than one row, `Mono` completes exceptionally emitting `IncorrectResultSizeDataAccessException`.
-* `all()`: Consume all returned rows returning a `Flux`.
-* `rowsUpdated`: Consume the number of affected rows.
-It is typically used with `INSERT`,`UPDATE`, and `DELETE` statements.
-
-[[r2dbc.datbaseclient.fluent-api.select]]
-== Selecting Data
-
-You can use the `select()` entry point to express your `SELECT` queries.
-The resulting `SELECT` queries support the commonly used clauses (`WHERE` and `ORDER BY`) and support pagination.
-The fluent API style let you chain together multiple methods while having easy-to-understand code.
-To improve readability, you can use static imports that let you avoid using the 'new' keyword for creating `Criteria` instances.
-
-[r2dbc.datbaseclient.fluent-api.criteria]]
-==== Methods for the Criteria Class
-
-The `Criteria` class provides the following methods, all of which correspond to SQL operators:
-
-* `Criteria` *and* `(String column)`: Adds a chained `Criteria` with the specified `property` to the current `Criteria` and returns the newly created one.
-* `Criteria` *or* `(String column)`: Adds a chained `Criteria` with the specified `property` to the current `Criteria` and returns the newly created one.
-* `Criteria` *greaterThan* `(Object o)`: Creates a criterion by using the `>` operator.
-* `Criteria` *greaterThanOrEquals* `(Object o)`: Creates a criterion by using the `>=` operator.
-* `Criteria` *in* `(Object... o)`: Creates a criterion by using the `IN` operator for a varargs argument.
-* `Criteria` *in* `(Collection<?> collection)`: Creates a criterion by using the `IN` operator using a collection.
-* `Criteria` *is* `(Object o)`: Creates a criterion by using column matching (`property = value`).
-* `Criteria` *isNull* `()`: Creates a criterion by using the `IS NULL` operator.
-* `Criteria` *isNotNull* `()`: Creates a criterion by using the `IS NOT NULL` operator.
-* `Criteria` *lessThan* `(Object o)`: Creates a criterion by using the `<` operator.
-* `Criteria` *lessThanOrEquals* `(Object o)`: Creates a criterion by using the `<=` operator.
-* `Criteria` *like* `(Object o)`: Creates a criterion by using the `LIKE` operator without escape character processing.
-* `Criteria` *not* `(Object o)`: Creates a criterion by using the `!=` operator.
-* `Criteria` *notIn* `(Object... o)`: Creates a criterion by using the `NOT IN` operator for a varargs argument.
-* `Criteria` *notIn* `(Collection<?> collection)`: Creates a criterion by using the `NOT IN` operator using a collection.
-
-You can use `Criteria` with `SELECT`, `UPDATE`, and `DELETE` queries.
-
-[r2dbc.datbaseclient.fluent-api.select.methods]]
-==== Methods for `SELECT` operations
-
-The `select()` entry point exposes some additional methods that provide options for the query:
-
-* *from* `(Class<T>)`: Specifies the source table by using a mapped object.
-By default, it returns results as `T`.
-* *from* `(String)`: Specifies the source table name.
-By default, it returns results as `Map<String, Object>`.
-* *as* `(Class<T>)`: Maps results to `T`.
-* *map* `(BiFunction<Row, RowMetadata, T>)`: Supplies a mapping function to extract results.
-* *project* `(String... columns)`: Specifies which columns to return.
-* *matching* `(Criteria)`: Declares a `WHERE` condition to filter results.
-* *orderBy* `(Order)`: Declares an `ORDER BY` clause to sort results.
-* *page* `(Page pageable)`: Retrieves a particular page within the result.
-It limits the size of the returned results and reads from an offset.
-* *fetch* `()`: Transition call declaration to the fetch stage to declare result consumption multiplicity.
-
-[[r2dbc.datbaseclient.fluent-api.insert]]
-== Inserting Data
-
-You can use the `insert()` entry point to insert data. Similar to `select()`, `insert()` allows free-form and mapped object inserts.
-
-Consider the following simple typed insert operation:
-
-====
-[source,java]
-----
-Mono<Void> insert = databaseClient.insert()
-        .into(Person.class)                       <1>
-        .using(new Person(…))                     <2>
-        .then();                                  <3>
-----
-<1> Using `Person` with the `into(…)` method sets the `INTO` table, based on mapping metadata.
-It also prepares the insert statement to accept `Person` objects for inserting.
-<2> Provide a scalar `Person` object.
-Alternatively, you can supply a `Publisher` to run a stream of `INSERT` statements.
-This method extracts all non-`null` values and inserts them.
-<3> Use `then()` to insert an object without consuming further details.
-Modifying statements allow consumption of the number of affected rows or tabular results for consuming generated keys.
-====
-
-Inserts also support untyped operations, as the following example shows:
-
-====
-[source,java]
-----
-Mono<Void> insert = databaseClient.insert()
-        .into("person")                           <1>
-        .value("firstname", "John")               <2>
-        .nullValue("lastname")                    <3>
-        .then();                                  <4>
-----
-<1> Start an insert into the `person` table.
-<2> Provide a non-null value for  `firstname`.
-<3> Set `lastname` to `null`.
-<3> Use `then()` to insert an object without consuming further details.

-* *into* `(String)`: Specifies the target table name.
-By default, it returns results as `Map<String, Object>`.
-* *using* `(T)`: Specifies the object to insert.
-* *using* `(Publisher<T>)`: Accepts a stream of objects to insert.
-* *table* `(String)`: Overrides the target table name.
-* *value* `(String, Object)`: Provides a column value to insert.
-* *nullValue* `(String)`: Provides a null value to insert.
-* *map* `(BiFunction<Row, RowMetadata, T>)`: Supplies a mapping function to extract results.
-* *then* `()`: Runs `INSERT` without consuming any results.
-* *fetch* `()`: Transition call declaration to the fetch stage to declare result consumption multiplicity.
-
-[[r2dbc.datbaseclient.fluent-api.update]]
-== Updating Data
-
-You can use the `update()` entry point to update rows.
-Updating data starts by specifying the table to update by accepting `Update` specifying assignments.
-It also accepts `Criteria` to create a `WHERE` clause.
-
-Consider the following simple typed update operation:
-
-====
-[source,java]
-----
-Person modified = …
-
-Mono<Void> update = databaseClient.update()
-  .table(Person.class)                      <1>
-  .using(modified)                          <2>
-  .then();                                  <3>
-----
-<1> Using `Person` with the `table(…)` method sets the table to update based on mapping metadata.
-<2> Provide a scalar `Person` object value.
-`using(…)` accepts the modified object and derives primary keys and updates all column values.
-<3> Use `then()` to update the rows of an object without consuming further details.
-Modifying statements also allow consumption of the number of affected rows.
-====
-
-Update also supports untyped operations, as the following example shows:

-Mono<Void> update = databaseClient.update()
-  .table("person")                           <1>
-  .using(Update.update("firstname", "Jane")) <2>
-  .matching(where("firstname").is("John"))   <3>
-  .then();                                   <4>
-----
-<1> Update the `person` table.
-<2> Provide a, `Update` definition of which columns to update.
-<3> The issued query declares a `WHERE` condition on `firstname` columns to filter the rows to update.

-= Initializing a `ConnectionFactory`
-
-The `org.springframework.data.r2dbc.connectionfactory.init` package provides support for initializing an existing `ConnectionFactory`.
-You may sometimes need to initialize an instance that runs on a server somewhere or an embedded database.
-
-== Initializing a Database by Using @Bean methods
-
-If you want to initialize a database and you can provide a reference to a `ConnectionFactory` bean, you can use the
-
-.Using `ConnectionFactoryInitializer` to initialize a `ConnectionFactory`
-====
-[source,java]
-----
-@Configuration
-public class InitializerConfiguration {
-
-	@Bean
-	public ConnectionFactoryInitializer initializer(ConnectionFactory connectionFactory) {
-
-		ConnectionFactoryInitializer initializer = new ConnectionFactoryInitializer();
-		initializer.setConnectionFactory(connectionFactory);
-
-		CompositeDatabasePopulator populator = new CompositeDatabasePopulator();
-		populator.addPopulators(new ResourceDatabasePopulator(new ClassPathResource("com/foo/sql/db-schema.sql")));
-		populator.addPopulators(new ResourceDatabasePopulator(new ClassPathResource("com/foo/sql/test-data1.sql")));
-		initializer.setDatabasePopulator(populator);
-
-		return initializer;
-	}
-}
-----
-====
-
-The preceding example runs the two specified scripts against the database.
-The first script creates a schema, and the second populates tables with a test data set.
-
-The default behavior of the database initializer is to unconditionally run the provided scripts.
-This may not always be what you want — for instance, if you run the scripts against a database that already has test data in it.
-The likelihood of accidentally deleting data is reduced by following the common pattern (shown earlier) of creating the tables first and then inserting the data.
-The first step fails if the tables already exist.
-
-However, to gain more control over the creation and deletion of existing data, `ConnectionFactoryInitializer` and `ResourceDatabasePopulator` support various switches such as switching the initialization on and off.
-
-Each statement should be separated by `;` or a new line if the `;` character is not present at all in the script. You can control that globally or script by script, as the following example shows:
-
-.Customizing statement separators
-====
-[source,java]
-----
-@Configuration
-public class InitializerConfiguration {
-
-	@Bean
-	public ConnectionFactoryInitializer initializer(ConnectionFactory connectionFactory) {
-
-		ConnectionFactoryInitializer initializer = new ConnectionFactoryInitializer();
-
-		initializer.setConnectionFactory(connectionFactory);
-
-		ResourceDatabasePopulator populator = new ResourceDatabasePopulator(new ClassPathResource("com/foo/sql/db-schema.sql"));
-		populator.setSeparator("@@");                                                <1>
-		initializer.setDatabasePopulator(populator);
-
-		return initializer;
-	}
-}
-----
-<1> Set the separator scripts to `@@`.
-====
-
-In this example, the schema scripts uses `@@` as statement separator.
-
-=== Initialization of Other Components that Depend on the Database
-
-A large class of applications (those that do not use the database until after the Spring context has started) can use the database initializer with no further complications.
-If your application is not one of those, you might need to read the rest of this section.
-
-The database initializer depends on a `ConnectionFactory` instance and runs the scripts provided in its initialization callback (analogous to an `init-method` in an XML bean definition, a `@PostConstruct` method in a component, or the `afterPropertiesSet()` method in a component that implements `InitializingBean`).
-If other beans depend on the same data source and use the data source in an initialization callback, there might be a problem because the data has not yet been initialized.
-A common example of this is a cache that initializes eagerly and loads data from the database on application startup.
-
-To get around this issue, you have two options:
-
-1. change your cache initialization strategy to a later phase or
-2. ensure that the database initializer is initialized first
-
-Changing your cache initialization strategy might be easy if the application is in your control and not otherwise. Some suggestions for how to implement this include:
-
-* Make the cache initialize lazily on first usage, which improves application startup time.
-* Have your cache or a separate component that initializes the cache implement Lifecycle or SmartLifecycle.
-When the application context starts, you can automatically start a `SmartLifecycle` by setting its `autoStartup` flag, and you can manually start a Lifecycle by calling `ConfigurableApplicationContext.start()` on the enclosing context.
-* Use a Spring `ApplicationEvent` or similar custom observer mechanism to trigger the cache initialization.
-`ContextRefreshedEvent` is always published by the context when it is ready for use (after all beans have been initialized), so that is often a useful hook (this is how the `SmartLifecycle` works by default).
-
-Ensuring that the database initializer is initialized first can also be easy.
-Some suggestions on how to implement this include:
-
-* Rely on the default behavior of the Spring `BeanFactory`, which is that beans are initialized in registration order.
-You can easily arrange that by adopting the common practice of a set of `@Import` configuration that order your application modules and ensuring that the database and database initialization are listed first.
-* Separate the `ConnectionFactory` and the business components that use it and control their startup order by putting them in separate `ApplicationContext` instances (for example, the parent context contains the `ConnectionFactory`, and the child context contains the business components).

-[[r2dbc.datbaseclient.statements]]
-= Executing Statements
-
-`DatabaseClient` provides the basic functionality of running a statement.
-The following example shows what you need to include for minimal but fully functional code that creates a new table:
-
-====
-[source,java]
-----
-Mono<Void> completion = client.execute("CREATE TABLE person (id VARCHAR(255) PRIMARY KEY, name VARCHAR(255), age INTEGER);")
-        .then();
-----
-====
-
-`DatabaseClient` is designed for convenient, fluent usage.
-It exposes intermediate, continuation, and terminal methods at each stage of the execution specification.
-The preceding example above uses `then()` to return a completion `Publisher` that completes as soon as the query (or queries, if the SQL query contains multiple statements) completes.
-
-NOTE: `execute(…)` accepts either the SQL query string or a query `Supplier<String>` to defer the actual query creation until the query is sent to the database.
-
-[[r2dbc.datbaseclient.queries]]
-== Running Queries
-
-SQL queries can return values or the number of affected rows.
-`DatabaseClient` can return the number of updated rows or the rows themselves, depending on the issued query.
-
-The following example shows an `UPDATE` statement that returns the number of updated rows:
-
-====
-[source,java]
-----
-Mono<Integer> affectedRows = client.execute("UPDATE person SET name = 'Joe'")
-        .fetch().rowsUpdated();
-----
-====
-
-Running a `SELECT` query returns a different type of result, in particular tabular results.
-Tabular data is typically consumed by streaming each `Row`.
-You might have noticed the use of `fetch()` in the previous example.
-`fetch()` is a continuation operator that lets you specify how much data you want to consume.
-
-====
-[source,java]
-----
-Mono<Map<String, Object>> first = client.execute("SELECT id, name FROM person")
-        .fetch().first();
-----
-====
-
-Calling `first()` returns the first row from the result and discards remaining rows.
-You can consume data with the following operators:
-
-* `first()` return the first row of the entire result.
-* `one()` returns exactly one result and fails if the result contains more rows.
-* `all()` returns all rows of the result.
-* `rowsUpdated()` returns the number of affected rows (`INSERT` count, `UPDATE` count).
-
-By default, `DatabaseClient` queries return their results as `Map` of column name to value.
-You can customize type mapping by applying an `as(Class<T>)` operator, as follows:
-
-====
-[source,java]
-----
-Flux<Person> all = client.execute("SELECT id, name FROM mytable")
-        .as(Person.class)
-        .fetch().all();
-----
-====
-
-`as(…)` applies <<mapping.conventions,Convention-based Object Mapping>> and maps the resulting columns to your POJO.
-
-[[r2dbc.datbaseclient.mapping]]
-== Mapping Results
-
-You can customize result extraction beyond `Map` and POJO result extraction by providing an extractor `BiFunction<Row, RowMetadata, T>`.
-The extractor function interacts directly with R2DBC's `Row` and `RowMetadata` objects and can return arbitrary values (singular values, collections and maps, and objects).
-
-The following example extracts the `id` column and emits its value:
-
-====
-[source,java]
-----
-Flux<String> names = client.execute("SELECT name FROM person")
-        .map((row, rowMetadata) -> row.get("id", String.class))
-        .all();
-----
-====
-
-[[r2dbc.datbaseclient.mapping.null]]
-.What about `null`?
-****
-Relational database results can contain `null` values.
-The Reactive Streams specification forbids the emission of `null` values.
-That requirement mandates proper `null` handling in the extractor function.
-While you can obtain `null` values from a `Row`, you must not emit a `null` value.
-You must wrap any `null` values in an object (for example, `Optional` for singular values) to make sure a `null` value is never returned directly by your extractor function.
-****
-
-[[r2dbc.datbaseclient.binding]]
-== Binding Values to Queries
-
-A typical application requires parameterized SQL statements to select or update rows according to some input.
-These are typically `SELECT` statements constrained by a `WHERE` clause or `INSERT` and `UPDATE` statements that accept input parameters.
-Parameterized statements bear the risk of SQL injection if parameters are not escaped properly.
-`DatabaseClient` leverages R2DBC's `bind` API to eliminate the risk of SQL injection for query parameters.
-You can provide a parameterized SQL statement with the `execute(…)` operator and bind parameters to the actual `Statement`.
-Your R2DBC driver then runs the statement by using prepared statements and parameter substitution.
-
-Parameter binding supports two binding strategies:
-
-* By Index, using zero-based parameter indexes.
-* By Name, using the placeholder name.
-
-The following example shows parameter binding for a query:
-
-====
-[source,java]
-----
-db.execute("INSERT INTO person (id, name, age) VALUES(:id, :name, :age)")
-    .bind("id", "joe")
-    .bind("name", "Joe")
-    .bind("age", 34);
-----
-====
-
-.R2DBC Native Bind Markers
-****
-R2DBC uses database-native bind markers that depend on the actual database vendor.
-As an example, Postgres uses indexed markers, such as `$1`, `$2`, `$n`.
-Another example is SQL Server, which uses named bind markers prefixed with `@`.
-
-This is different from JDBC, which requires `?` as bind markers.
-In JDBC, the actual drivers translate `?` bind markers to database-native markers as part of processing the statement.
-
-Spring Data R2DBC lets you use native bind markers or named bind markers with the `:name` syntax.
-
-Named parameter support uses a `R2dbcDialect` instance to expand named parameters to native bind markers at the time of running the query, which gives you a certain degree of query portability across various database vendors.
-****
-
-The query-preprocessor unrolls named `Collection` parameters into a series of bind markers to remove the need of dynamic query creation based on the number of arguments.
-Nested object arrays are expanded to allow usage of (for example) select lists.
-
-Consider the following query:
-
-====
-[source,sql]
-----
-SELECT id, name, state FROM table WHERE (name, age) IN (('John', 35), ('Ann', 50))
-----
-====
-
-The preceding query can be parametrized and run as follows:
-
-====
-[source,java]
-----
-List<Object[]> tuples = new ArrayList<>();
-tuples.add(new Object[] {"John", 35});
-tuples.add(new Object[] {"Ann",  50});
-
-db.execute("SELECT id, name, state FROM table WHERE (name, age) IN (:tuples)")
-    .bind("tuples", tuples)
-----
-====
-
-NOTE: Usage of select lists is vendor-dependent.
-
-The following example shows a simpler variant using `IN` predicates:
-
-====
-[source,java]
-----
-db.execute("SELECT id, name, state FROM table WHERE age IN (:ages)")
-    .bind("ages", Arrays.asList(35, 50))
-----
-====
-
-[[r2dbc.datbaseclient.filter]]
-== Statement Filters
-
-You can register a `Statement` filter (`StatementFilterFunction`) through `DatabaseClient` to intercept and modify statements when they run, as the following example shows:
-
-====
-[source,java]
-----
-db.execute("INSERT INTO table (name, state) VALUES(:name, :state)")
-    .filter((s, next) -> next.execute(s.returnGeneratedValues("id")))
-    .bind("name", …)
-    .bind("state", …)
-----
-====
-
-`DatabaseClient` exposes also simplified `filter(…)` overload accepting `UnaryOperator<Statement>`:
-
-====
-[source,java]
-----
-db.execute("INSERT INTO table (name, state) VALUES(:name, :state)")
-    .filter(s -> s.returnGeneratedValues("id"))
-    .bind("name", …)
-    .bind("state", …)
-
-db.execute("SELECT id, name, state FROM table")
-    .filter(s -> s.fetchSize(25))
-----
-====
-
-`StatementFilterFunction` allows filtering of the `Statement` and filtering of the `Result` objects.

+[[r2dbc.entityoperations]]
+= R2dbcEntityOperations Data Access API
+
+`R2dbcEntityTemplate` is the central entrypoint for Spring Data R2DBC.
+It provides direct entity-oriented methods and a more narrow, fluent interface for typical ad-hoc use-cases, such as querying, inserting, updating, and deleting data.
+
+The entry points (`insert()`, `select()`, `update()`, and others) follow a natural naming schema based on the operation to be run.
+Moving on from the entry point, the API is designed to offer only context-dependent methods that lead to a terminating method that creates and runs a SQL statement.
+Spring Data R2DBC uses a `R2dbcDialect` abstraction to determine bind markers, pagination support and the data types natively supported by the underlying driver.
+
+NOTE: All terminal methods return always a `Publisher` type that represents the desired operation.
+The actual statements are sent to the database upon subscription.
+
+[[r2dbc.entityoperations.save-insert]]
+== Methods for Inserting and Updating Entities
+
+There are several convenient methods on `R2dbcEntityTemplate` for saving and inserting your objects.
+To have more fine-grained control over the conversion process, you can register Spring converters with `R2dbcCustomConversions` -- for example  `Converter<Person, OutboundRow>` and `Converter<Row, Person>`.
+
+The simple case of using the save operation is to save a POJO. In this case, the table name is determined by name (not fully qualified) of the class.
+You may also call the save operation with a specific collection name.
+You can use mapping metadata to override the collection in which to store the object.
+
+When inserting or saving, if the `Id` property is not set, the assumption is that its value will be auto-generated by the database.
+Consequently, for auto-generation the type of the `Id` property or field in your class must be a `Long`, or `Integer`.
+
+The following example shows how to insert a row and retrieving its contents:
+
+.Inserting and retrieving entities using the `R2dbcEntityTemplate`
+====
+[source,java,indent=0]
+----
+include::../{example-root}/R2dbcEntityTemplateSnippets.java[tags=insertAndSelect]
+----
+====
+
+The following insert and update operations are available:
+
+A similar set of insert operations is also available:
+
+* `Mono<T>` *insert* `(T objectToSave)`: Insert the object to the default table.
+* `Mono<T>` *update* `(T objectToSave)`: Insert the object to the default table.
+
+Table names can be customized by using the fluent API.
+
+[[r2dbc.entityoperations.selecting]]
+== Selecting Data
+
+The `select(…)` and `selectOne(…)` methods on `R2dbcEntityTemplate` are used to select data from a table.
+Both methods take a <<r2dbc.datbaseclient.fluent-api.criteria,`Query`>> object that defines the field projection, the `WHERE` clause, the `ORDER BY` clause and limit/offset pagination.
+Limit/offset functionality is transparent to the application regardless of the underlying database.
+This functionality is supported by the <<r2dbc.drivers,`R2dbcDialect` abstraction>> to cater for differences between the individual SQL flavors.
+
+.Selecting entities using the `R2dbcEntityTemplate`

+----
+include::../{example-root}/R2dbcEntityTemplateSnippets.java[tags=select]
+----
+====
+
+[[r2dbc.entityoperations.fluent-api]]
+== Fluent API
+
+This section explains the fluent API usage.
+Consider the following simple query:
+
+====
+[source,java,indent=0]
+----
+include::../{example-root}/R2dbcEntityTemplateSnippets.java[tags=simpleSelect]
+----
+<1> Using `Person` with the `from(…)` method sets the `FROM` table based on mapping metadata.
+It also maps tabular results on `Person` result objects.
+<2> Fetching `all()` rows returns a `Flux<Person>` without limiting results.
+====
+
+The following example declares a more complex query that specifies the table name by name, a `WHERE` condition, and an `ORDER BY` clause:
+
+====
+[source,java,indent=0]
+----
+include::../{example-root}/R2dbcEntityTemplateSnippets.java[tags=fullSelect]
+----
+<1> Selecting from a table by name returns row results using the given domain type.
+<2> The issued query declares a `WHERE` condition on `firstname` and `lastname` columns to filter results.
+<3> Results can be ordered by individual column names, resulting in an `ORDER BY` clause.
+<4> Selecting the one result fetches only a single row.
+This way of consuming rows expects the query to return exactly a single result.
+`Mono` emits a `IncorrectResultSizeDataAccessException` if the query yields more than a single result.
+====
+
+TIP: You can directly apply <<projections,Projections>> to results by providing the target type via `select(Class<?>)`.
+
+You can switch between retrieving a single entity and retrieving multiple entities through the following terminating methods:
+
+* `first()`: Consume only the first row, returning a `Mono`.
+The returned `Mono` completes without emitting an object if the query returns no results.
+* `one()`: Consume exactly one row, returning a `Mono`.
+The returned `Mono` completes without emitting an object if the query returns no results.
+If the query returns more than one row, `Mono` completes exceptionally emitting `IncorrectResultSizeDataAccessException`.
+* `all()`: Consume all returned rows returning a `Flux`.
+* `count()`: Apply a count projection returning `Mono<Long>`.
+* `exists()`: Return whether the query yields any rows by returning `Mono<Boolean>`.
+
+You can use the `select()` entry point to express your `SELECT` queries.
+The resulting `SELECT` queries support the commonly used clauses (`WHERE` and `ORDER BY`) and support pagination.
+The fluent API style let you chain together multiple methods while having easy-to-understand code.
+To improve readability, you can use static imports that let you avoid using the 'new' keyword for creating `Criteria` instances.
+
+[[r2dbc.datbaseclient.fluent-api.criteria]]
+=== Methods for the Criteria Class
+
+The `Criteria` class provides the following methods, all of which correspond to SQL operators:
+
+* `Criteria` *and* `(String column)`: Adds a chained `Criteria` with the specified `property` to the current `Criteria` and returns the newly created one.
+* `Criteria` *or* `(String column)`: Adds a chained `Criteria` with the specified `property` to the current `Criteria` and returns the newly created one.
+* `Criteria` *greaterThan* `(Object o)`: Creates a criterion by using the `>` operator.
+* `Criteria` *greaterThanOrEquals* `(Object o)`: Creates a criterion by using the `>=` operator.
+* `Criteria` *in* `(Object... o)`: Creates a criterion by using the `IN` operator for a varargs argument.
+* `Criteria` *in* `(Collection<?> collection)`: Creates a criterion by using the `IN` operator using a collection.
+* `Criteria` *is* `(Object o)`: Creates a criterion by using column matching (`property = value`).
+* `Criteria` *isNull* `()`: Creates a criterion by using the `IS NULL` operator.
+* `Criteria` *isNotNull* `()`: Creates a criterion by using the `IS NOT NULL` operator.
+* `Criteria` *lessThan* `(Object o)`: Creates a criterion by using the `<` operator.
+* `Criteria` *lessThanOrEquals* `(Object o)`: Creates a criterion by using the `<=` operator.
+* `Criteria` *like* `(Object o)`: Creates a criterion by using the `LIKE` operator without escape character processing.
+* `Criteria` *not* `(Object o)`: Creates a criterion by using the `!=` operator.
+* `Criteria` *notIn* `(Object... o)`: Creates a criterion by using the `NOT IN` operator for a varargs argument.
+* `Criteria` *notIn* `(Collection<?> collection)`: Creates a criterion by using the `NOT IN` operator using a collection.
+
+You can use `Criteria` with `SELECT`, `UPDATE`, and `DELETE` queries.
+
+[[r2dbc.entityoperations.fluent-api.insert]]
+== Inserting Data
+
+You can use the `insert()` entry point to insert data.
+
+Consider the following simple typed insert operation:
+
+====
+[source,java,indent=0]
+----
+include::../{example-root}/R2dbcEntityTemplateSnippets.java[tags=insert]
+----
+<1> Using `Person` with the `into(…)` method sets the `INTO` table, based on mapping metadata.
+It also prepares the insert statement to accept `Person` objects for inserting.
+<2> Provide a scalar `Person` object.
+Alternatively, you can supply a `Publisher` to run a stream of `INSERT` statements.
+This method extracts all non-`null` values and inserts them.
+====
+
+[[r2dbc.entityoperations.fluent-api.update]]
+== Updating Data
+
+You can use the `update()` entry point to update rows.
+Updating data starts by specifying the table to update by accepting `Update` specifying assignments.
+It also accepts `Query` to create a `WHERE` clause.
+
+Consider the following simple typed update operation:
+
+====
+[source,java]
+----
+Person modified = …
+
+include::../{example-root}/R2dbcEntityTemplateSnippets.java[tags=update]
+----
+<1> Update `Person` objects and apply mapping based on mapping metadata.
+<2> Set a different table name by calling the `inTable(…)` method.
+<2> Specify a query that translates into a `WHERE` clause.
+<3> Apply the `Update` object.
+Set in this case `age` to `42` and return the number of affected rows.
+====
+
+[[r2dbc.entityoperations.fluent-api.delete]]
+== Deleting Data
+
+You can use the `delete()` entry point to delete rows.
+Removing data starts with a specification of the table to delete from and, optionally, accepts a `Criteria` to create a `WHERE` clause.
+
+Consider the following simple insert operation:
+
+====
+[source,java]
+----
+include::../{example-root}/R2dbcEntityTemplateSnippets.java[tags=delete]
+----
+<1> Delete `Person` objects and apply mapping based on mapping metadata.
+<2> Set a different table name by calling the `from(…)` method.
+<2> Specify a query that translates into a `WHERE` clause.
+<3> Apply the delete operation and return the number of affected rows.

Subject: [PATCH 1007/2145] #468 - Correctly map result of exists queries.

We now map results of exists queries to a boolean flag to ensure proper decoding. Previously, results were attempted to be mapped onto a primitive type which failed as there's no converter registered for Row to Boolean.

From 9cd8fc16b35cf7bef2deea38d190213f6fcaceb0 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1010/2145] DATAJDBC-508 - Add support for @Value in
 persistence constructors.

We now evaluate @Value annotations in persistence constructors to compute values when creating object instances. AtValue can be used to materialize values for e.g. transient properties. Root properties map to the ResultSet from which an object gets materialized.

class WithAtValue {

	private final @Id Long id;
	private final @Transient String computed;

	public WithAtValue(Long id,
			@Value("#root.first_name") String computed) { // obtain value from first_name column
		this.id = id;
			this.computed = computed;
		}
	}

Subject: [PATCH 1013/2145] #469 - Suppress emission of null values when using
 simple and primitive result types.

Results projected onto simple and primitive types that are null are no longer emitted.

A SQL query SELECT MAX(age) FROM my_table that returns a SQL NULL and that would be consumed as Long.class (Publisher<Long>) is an example for a primitive type that can be null. Since Reactive Streams prohibits the propagation of null values by a Publisher to a Subscriber the only viable option is to suppress null results by wrapping the mapping function into Optional result values and filter these values later to avoid null being emitted.

Subject: [PATCH 1015/2145] #465 - Convert bind values for String-based queries
 to their native type.

We now invoke the converter for query arguments of String-based queries (using the Query annotation or named queries) to convert the value into a type that can be used by the driver.

Previously all values were passed-thru which caused for e.g. enums to pass-thru these to the driver and the driver encode failed.

Subject: [PATCH 1017/2145] #475 - Refine projection result mapping.

We now differentiate the result mapping based on projection type and query type. Previously, all projections used the domain type to map results first and then serve as backend for the projection proxy/DTO creation.
We now use direct result to DTO mapping for String-based queries to allow for a greater flexibility when declaring DTO result types. Interface-based projections and derived queries remain using the two-step process of result to domain type mapping and then mapping the domain type into the projection.

+[[projections.resultmapping]]
+==== Result Mapping
+
+A query method returning an Interface- or DTO projection is backed by results produced by the actual query.
+Interface projections generally rely on mapping results onto the domain type first to consider potential `@Column` type mappings and the actual projection proxy uses a potentially partially materialized entity to expose projection data.
+
+Result mapping for DTO projections depends on the actual query type.
+Derived queries use the domain type to map results, and Spring Data creates DTO instances solely from properties available on the domain type.
+Declaring properties in your DTO that are not available on the domain type is not supported.
+
+String-based queries use a different approach since the actual query, specifically the field projection, and result type declaration are close together.
+DTO projections used with query methods annotated with `@Query` map query results directly into the DTO type.
+Field mappings on the domain type are not considered.
+Using the DTO type directly, your query method can benefit from a more dynamic projection that isn't restricted to the domain model.

Renames *Bean annotation attributes to *Ref to match other similar attributes.
Removes additional arguments from constructors of public classes in order to avoid breaking the API.
Gathers application context configuration for StringBasedJdbcQueryMappingConfigurationIntegrationTests in a single java file.
Formatting.
Adds the author tag.
Changes default value of references to the empty String.

Original pull request: #249.

Subject: [PATCH 1081/2145] DATAJDBC-641 - Removes references of
 org.jetbrains.annotations.NotNull.

Those annotations cause build failures once the providing jar wasn't available anymore since kotlin removed that dependency.

Those annotations were present in the code by accident anyway since Spring has and uses its own set of annotations.

Subject: [PATCH 1100/2145] DATAJDBC-637 - Time conversion now preserve
 nanosecond precision.

The standard JSR 310 converters are no longer used for conversions between java.util.Date and java.time.*.
New converters based converting to/from Timestamp are used.

This preserves the precision because both the java.time.* API and Timestamp have nanosecond precision, while java.util.Date has not.

Original pull request: #254.

Subject: [PATCH 1113/2145] Apply UPPER function to all columns when enabling
 ignoreCase.

We now apply the UPPER function regardless of whether we could resolve the criteria property to a column. Previously, we required a resolved property of a String type which prevented non-mapped properties from case-insensitive queries.

Closes #518

Subject: [PATCH 1115/2145] Read domain type when returning an implemented
 interface from repository query methods.

We now read the domain type instead of trying to materialize an interface if the type returned from the query method is implemented by the domain object handled by the repository.

Closes #519

+[[r2dbc.repositories.queries.query-by-example]]
+=== Query By Example
+
+Spring Data R2DBC also lets you use Query By Example to fashion queries.
+This technique allows you to use a "probe" object.
+Essentially, any field that isn't empty or `null` will be used to match.
+
+Here's an example:
+
+====
+[source,java,indent=0]
+----
+include::../{example-root}/QueryByExampleTests.java[tag=example]
+----
+<1> Create a domain object with the criteria (`null` fields will be ignored).
+<2> Using the domain object, create an `Example`.
+<3> Through the `R2dbcRepository`, execute query (use `findOne` for a `Mono`).
+====
+
+This illustrates how to craft a simple probe using a domain object.
+In this case, it will query based on the `Employee` object's `name` field being equal to `Frodo`.
+`null` fields are ignored.
+
+====
+[source,java,indent=0]
+----
+include::../{example-root}/QueryByExampleTests.java[tag=example-2]
+----
+<1> Create a custom `ExampleMatcher` that matches on ALL fields (use `matchingAny()` to match on *ANY* fields)
+<2> For the `name` field, use a wildcard that matches against the end of the field
+<3> Match columns against `null` (don't forget that `NULL` doesn't equal `NULL` in relational databases).
+<4> Ignore the `role` field when forming the query.
+<5> Plug the custom `ExampleMatcher` into the probe.
+====
+
+It's also possible to apply a `withTransform()` against any property, allowing you to transform a property before forming the query.
+For example, you can apply a `toUpperCase()` to a `String` -based property before the query is created.
+
+Query By Example really shines when you you don't know all the fields needed in a query in advance.
+If you were building a filter on a web page where the user can pick the fields, Query By Example is a great way to flexibly capture that into an efficient query.

Subject: [PATCH 1177/2145] Fully consume insert response.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

R2dbcEntityTemplate.insert(…) now fully consumes the response from the INSERT call before continuing. Previously, we consumed only the first signal and continued then. A driver could emit a row and then an error signal and so the error signal would go unnoticed.

Closes #552.

Subject: [PATCH 1178/2145] JdbcCustomConversion does not reject non-Date
 related default converters.

Previously, JdbcCustomConversion rejected any default converter that was not converting from and to java.util.Date. This probably stemmed from the fact that up until recently, Spring Data Commons' CustomConversions only registered date related default converters. As of spring-projects/spring-data-commons#2315 we also support jMolecules' Association and Identifier converters. We've relaxed the rejection to only explicitly reject all non Date/Time related converters if the conversion is from/to java.util.Date but allow everything else out of the box.

Subject: [PATCH 1179/2145] Move to Spring Data Commons' association
 abstraction.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Deprecated Spring Data JDBC's custom PersistentProperty.isReference() in favor of the already existing ….isAssociation() with the same semantics to benefit from association definitions implemented in Spring Data Commons. Make use of the newly introduced PersistentEntity.doWithAll(…) to apply the previously existing property handling to both properties and now associations, too.

Subject: [PATCH 1184/2145] Add support for Oracle's R2DBC driver.

We support Oracle's experimental R2DBC driver by providing a dialect including bind markers. Since the driver is not yet available from Maven Central and it requires module-path support for ServiceLoader discovery, we need to apply a few workarounds including absence check for our integration tests.

See #230

Subject: [PATCH 1186/2145] Move default Id value cleanup on insert from
 Converter into R2dbcEntityTemplate.

We now check in R2dbcEntityTemplate whether we need to skip the Id value if its value is null or a primitive using its default. Previously, the check was located in the converter. Converting an entity afteri ncrementing the version of a versioned entity would write the Id value as the entity was no longer considered to be new.

Closes #557.

Subject: [PATCH 1207/2145] Polishing.

Refactor ArrayUtil into a proper utility class providing toPrimitive and toObject methods for each primitive type. Add boolean support. Move convertToObjectArray to BasicJdbcConverter as its placement in ArrayUtils creates a certain amount of ambiguity over its actual purpose.

Create unit test.

Subject: [PATCH 1224/2145] Add support for Slice and Page queries using query
 derivation.

We now support pagination for queries returning Slice and Page.

interface PersonRepository extends PagingAndSortingRepository<Person, String> {

  Slice<Person> findFirstByLastname(String lastname, Pageable pageable);

  Page<Person> findFirstByLastname(String lastname, Pageable pageable);
}

Closes #774

 The query is derived by parsing the method name for constraints that can be concatenated with `And` and `Or`.

-=== Entity State Detection Strategies
-
-The following table describes the strategies that Spring Data JDBC offers for detecting whether an entity is new:
-
-.Options for detection whether an entity is new in Spring Data JDBC
-[options = "autowidth"]
-|===============
-|Id-Property inspection (the default)|By default, Spring Data JDBC inspects the identifier property of the given entity.
-If the identifier property is `null`, then the entity is assumed to be new. Otherwise, it is assumed to not be new.
-|Implementing `Persistable`|If an entity implements `Persistable`, Spring Data JDBC delegates the new detection to the `isNew(…)` method of the entity.
-See the link:$$https://docs.spring.io/spring-data/data-commons/docs/current/api/index.html?org/springframework/data/domain/Persistable.html$$[Javadoc] for details.
-|Implementing `EntityInformation`|You can customize the `EntityInformation` abstraction used in the `SimpleJdbcRepository` implementation by creating a subclass of `JdbcRepositoryFactory` and overriding the `getEntityInformation(…)` method.
-You then have to register the custom implementation of `JdbcRepositoryFactory` as a Spring bean.
-Note that this should rarely be necessary. See the link:{javadoc-base}org/springframework/data/jdbc/repository/support/JdbcRepositoryFactory.html[Javadoc] for details.

 [[r2dbc.entity-persistence.state-detection-strategies]]
-=== Entity State Detection Strategies
-
-The following table describes the strategies that Spring Data R2DBC offers for detecting whether an entity is new:
-
-.Options for detection whether an entity is new in Spring Data R2DBC
-[options = "autowidth"]
-|===============
-|Id-Property inspection (the default)   |By default, the `save()` method inspects the identifier property of the given entity.
-If the identifier property is `null`, then the entity is assumed to be new. Otherwise, it is assumed exist in the datbase.
-|Implementing `Persistable`             |If an entity implements `Persistable`, Spring Data R2DBC delegates the new detection to the `isNew(…)` method of the entity.
-See the link:$$https://docs.spring.io/spring-data/data-commons/docs/current/api/index.html?org/springframework/data/domain/Persistable.html$$[Javadoc] for details.
-|Optimistic Locking through `@Version`  | If an entity uses Optimistic Locking by (version property annotated with `@Version`), Spring Data R2DBC checks if the entity is new by inspecting the version property whether its value corresponds with Java's default initialization value. That is `0` for primitive types and `null` for wrapper types.
-|Implementing `EntityInformation`       |You can customize the `EntityInformation` abstraction used in `SimpleR2dbcRepository`  by creating a subclass of `R2dbcRepositoryFactory` and overriding `getEntityInformation(…)`.
-You then have to register the custom implementation of `R2dbcRepositoryFactory` as a Spring bean.
-Note that this should rarely be necessary. See the link:{spring-data-r2dbc-javadoc}/org/springframework/data/r2dbc/repository/support/R2dbcRepositoryFactory.html[Javadoc] for details.

 =?UTF-8?q?ll(=E2=80=A6)=20should=20call=20bindSpec.bindNull(=E2=80=A6).?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The wrong call is not caught by the compiler due to a bind method that has a signature of (String name, Object value).
Previously, bindNull(…) called bind(…).

Closes #587.

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of

Date: Mon, 3 May 2021 15:53:15 +0200
Subject: [PATCH 1262/2145] Correctly translate absent convertible enum values
 to String[] using Postgres.

We now correctly obtain the target type for a persistent property that should be converted into an array value prior to constructing Parameter.
Previously, we fell back to the actual type without considering potential converters which left collection-like enum properties without a value with the enum array type that was potentially not supported by the database driver.

Closes #593

Subject: [PATCH 1264/2145] Refactor query method execution to use
 R2dbcEntityTemplate.

Repository query methods are now executed through R2dbcEntityTemplate to participate in entity callbacks.
Previously, query methods were executed directly using DatabaseClient which didn't allow for entity callbacks.

Closes #591

Subject: [PATCH 1265/2145] Upgrades MySql for testing to 8.0.24.

This version of the docker container doesn't allow to use `root` as the database user name.
We still have to connect as `root` so we can create alternative schemata.

From 1ca628922df67748fe6ce1accb91d7294fb9b586 Mon Sep 17 00:00:00 2001
From: Jens Schauder <jschauder@vmware.com>
Date: Fri, 14 May 2021 10:36:49 +0200
Subject: [PATCH 1273/2145] Fixes build failures with JDK16.

`JdbcMappingContext` sets the SimpleTypeHolder to `JdbcSimpleTypeHolder.HOLDER` by default.
Fixing test failures where properties of type `UUID` were considered an entity by the `MappingContext`.
This in turn triggered failures when it tried to make fields of `UUID` accessible.

Removed the `UUID` field from a test entity in SD Relational, since `UUID` is not a simple type for Relational, nor a proper entity.

Replaced `@PostConstruct` with `InitializingBean` in test data source conifgurations in order avoid the requirement of importing javax.annotation-api.

Closes #975

Subject: [PATCH 1283/2145] Refine conversion directions between boolean and
 byte using MySQL/MariaDB.

ByteToBooleanConverter is now marked as reading converter and we've added a writing converter with BooleanToByteConverter to ensure proper conversion. Previously, all byte values were converted to boolean resulting in data precision loss.

Closes #589

Subject: [PATCH 1284/2145] Support for Dialect specific custom conversions and
 OffsetDateTime.

Dialects may now register a list of converters to take into consideration when reading or writing properties.

See `JdbcSqlServerDialect` for an example.

By default `OffsetDateTime` does not get converted anymore.
If a database needs a conversion it can register it by implementing `Dialect.getConverters()` as described above.

Closes #935
Original pull request #981

Subject: [PATCH 1286/2145] Avoid conversion warnings for store specific simple
 types.

Dialects now can define a set of known simple types the driver can handle without further interaction. This is done to avoid warnings during converter registration for types known in one environment but not the other.
Also move types around a bit, change visibility and make sure jdbc specific dialects inherit converters from their parents.

Subject: [PATCH 1289/2145] Do not convert from LocalDateTime to Timestamp by
 default.

Most supported databases don't need that conversion.

Db2 does need it and gets it through JdbcDb2Dialect.

As part of the effort it became obvious that the filtering for conversions between Date and JSR310 data types was broken.
It is fixed now, which required a dedicated reading conversion from LocalDateTime to Date for JdbcMySqlDialect.

Closes #974
Original pull request: #985.

From 4c6894464e1c54d9310ca27654f1da622a25517f Mon Sep 17 00:00:00 2001
From: Jens Schauder <jschauder@vmware.com>
Date: Wed, 26 May 2021 08:04:33 +0200
Subject: [PATCH 1290/2145] Fix derived queries with boolean literals.

`IsTrue` and `IsFalse` queries no longer use a literal in the query, but a bind parameter.
This allows Spring Data JDBC or the JDBC driver to convert the passed boolean value to whatever is required in the database.

For Oracle converter where added to support storing and loading booleans as NUMBER(1,0) where 0 is false and everything else is true.

Closes #908
Original pull request #983

+NOTE: In previous versions of Spring Data JDBC it was recommended to directly overwrite `AbstractJdbcConfiguration.jdbcCustomConversions()`.
+This is no longer necessary or even recommended, since that method assembles conversions intended for all databases, conversions registered by the `Dialect` used and conversions registered by the user.
+If you are migrating from an older version of Spring Data JDBC and have `AbstractJdbcConfiguration.jdbcCustomConversions()` overwritten conversions from your `Dialect` will not get registered.

+Register a custom write converter if you need to specify a JDBC-specific type instead of using type derivation.
+This converter should convert the value to `JdbcValue` which has a field for the value and for the actual `JDBCType`.

-Converters should be annotated with `@ReadingConverter` or `@WritingConverter` in order to control their applicability to only reading from or to writing to the database.

Subject: [PATCH 1292/2145] Registration of columns for generated keys is now
 dialect dependent.

Different R2DBC drivers expect generated keys when they are in camel case to be quoted or unquoted.
This can now be controlled by implementing `Dialect.renderForGeneratedKeys`.

Closes: #483

Subject: [PATCH 1294/2145] Fix dynamic query method projection.

Query methods returning dynamic projections based on a Class argument now properly apply projection conversion. Previously, classes not seen by the mapping context were skipped and that caused projecting query methods to return the actual entity type.

Closes #607

Use queryForStream for streamed query results.
Since ResultSetExtractor cannot be reasonably be used together with streams it falls back to the existing collection behaviour.

+==== Streaming Results
+
+When you specify `Stream` as the return type of a query method Spring Data JDBC will return elements as soon as they become available.
+When dealing with large amounts of data this is suitable for reducing latency and memory requirements.
+
+The stream contains an open connection to the database.
+To avoid memory leaks that connection needs to be closed eventually by closing the stream.
+The recommended way to do that is a try-with-resource clause.
+It also means once the connection to the database is closed, the stream cannot obtain further elements and will likely throw an exception.

 In contrast to that, `deleteInactiveUsers()` uses the `@Modifying` annotation and overrides the transaction configuration.

-NOTE: It is definitely reasonable to use transactions for read-only queries, and we can mark them as such by setting the `readOnly` flag.
+NOTE: It is highly recommended to make query methods transactional. These methods might execute more then one query in order to populate an entity.
+Without a common transaction Spring Data JDBC executes the queries in different connections.
+This may put excessive strain on the connection pool and might even lead to dead locks when multiple methods request a fresh connection while holding on to one.

+NOTE: It is definitely reasonable to mark read-only queries as such by setting the `readOnly` flag.
 This does not, however, act as a check that you do not trigger a manipulating query (although some databases reject `INSERT` and `UPDATE` statements inside a read-only transaction).
 Instead, the `readOnly` flag is propagated as a hint to the underlying JDBC driver for performance optimizations.

Subject: [PATCH 1325/2145] Deprecate R2dbcCustomConversions constructor taking
 Collection of converters.

Creating R2dbcCustomConversions without a dialect or StoreConversions can easily lead to misconfiguration that isn't immediately obvious because of missing store simple types. We now deprecated the constructor and have added guidance on how to properly create R2dbcCustomConversions that is associated with a dialect.

Closes #628

Subject: [PATCH 1355/2145] Fix ReactiveQueryMethodEvaluationContextProvider
 initialization in R2dbcRepositoryFactoryBean.

We now correctly in initialize ReactiveQueryMethodEvaluationContextProvider in the repository factory bean. Previously, we used an empty instance of ReactiveQueryMethodEvaluationContextProvider that didn't consider registered extensions.

From f6eacf327cff3476a51023636b79a961b9889db1 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1356/2145] Support for in line queries for tables.

`InlineQuery` can be used wherever a `Table` was used up to now.

```
Table one = ...;
Select select = Select.builder()
		.select(one.column("id"), employee.column("name"))
		.from(one)
		.build();

InlineQuery inline = InlineQuery.create(select, "inline");
Select select = Select.builder()
		.select(inline.column("id"), inline.column("name"))
		.from(inline)
		.build();
```

Join and From renderer now use the same FromTableVisitor.
Also the SelectListVisitor reuses now the ExpressionVisitor.

Fixes #1003
Original pull request: #1018.

Subject: [PATCH 1365/2145] SQL type used in array construction depends on
 Dialect.

Postgres requires the non standard type "FLOAT8" for "DOUBLE".
This is accomplished by making the conversion dependent on the dialect.

This required a new JdbcDialect interface in order to keep the JDBC annotation out of the relational module.

Closes #1033
Original pull request: #1037.

Subject: [PATCH 1368/2145] Introducing AfterConvertCallback/Event.

This is to replace the AfterLoadCallback/Event in order to match the naming of other store modules.

AfterLoadCallback/Event is still in place for now, but deprecated.

Closes #1053
Original pull request: #1060.

Subject: [PATCH 1390/2145] Avoid nested entity creation if column value is

We now no longer attempt to create instances of nested entities if the column value is null. Previously the null check happened after checking registered custom conversions which has lead to potential object creation for columns containing null values.

Subject: [PATCH 1391/2145] Make Oracle tests work with Testcontainers 1.16.2.

The new Testcontainers version comes with a standard Oracle image configured and doesn't work with the one we used so far.
Making the standard image work required some tweaks to the setup so that the test user has the required privileges.

Closes #1081

Subject: [PATCH 1412/2145] Polishing.

Simplified the code structure.
Ensured backward compatibility by recreating some methods often immediately deprecating them.

Moved new classes to the places where they belong, so that the package ...core.sql.render depends on ...core.dialect and not the other way round.
This causes dependency cycles because dependencies in the other direction already exists.
This will be properly fixed by #1105.
For now the offending classes are ignored by the DependencyTests.

See #777
See #1105

Subject: [PATCH 1421/2145] Polishing.

Removed jetbrains annotation.
Removed attempt to cache annotation lookup.
Those lookups are already cached and obtaining them in the constructor causes overhead when they aren't requested at all.
Limit the use of Optional.

Subject: [PATCH 1424/2145] Unwrap Parameter objects when used within
 PreparedOperation.

We now unwrap Parameter objects containing type and value for bind parameters when binding these from within a PreparedOperation to a statement.

PreparedOperation objects are expected to use low-level R2DBC API (bind, bindNull) instead of using the Parameter abstraction. Previously, we tried to bind Parameter objects to R2DBC Statements and that has failed as drivers cannot encode Spring's Pararameter type.

Closes #694

With older versions H2 returned a proprietary  instance of `TimestampWithTimeZone` from `ResultSet.getObject()`.
We used to support the conversion of that to an `OffsetDateTime`.

With the most recent versions `TimestampWithTimeZone` is no longer part of the H2 driver, and we only register the converter when we encounter older versions of H2.

Closes #1114
See https://github.com/h2database/h2database/pull/1359

Subject: [PATCH 1427/2145] Reflectively invoke RowMetadata.getColumnMetadatas.

We now use reflection to call RowMetadata.getColumnMetadatas to avoid NoSuchMethodError when using R2DBC 0.9 as the return type has changed in newer R2DBC versions.

Closes #699

Subject: [PATCH 1456/2145] Guard access to identifier property.

We now check in all places where we optionally use the Id property that an entity actually has an Id property and fall back leniently if the entity doesn't have an identifier property.

Also, we use IdentifierAccessor consistently if the property is an identifier property.

See #711

-/**
- * {@link org.springframework.transaction.ReactiveTransactionManager} implementation for a single R2DBC
- * {@link ConnectionFactory}. This class is capable of working in any environment with any R2DBC driver, as long as the
- * setup uses a {@link ConnectionFactory} as its {@link Connection} factory mechanism. Binds a R2DBC {@link Connection}
- * from the specified {@link ConnectionFactory} to the current subscriber context, potentially allowing for one
- * context-bound {@link Connection} per {@link ConnectionFactory}.
- * <p>
- * <b>Note: The {@link ConnectionFactory} that this transaction manager operates on needs to return independent
- * {@link Connection}s.</b> The {@link Connection}s may come from a pool (the typical case), but the
- * {@link ConnectionFactory} must not return scoped scoped {@link Connection}s or the like. This transaction manager
- * will associate {@link Connection} with context-bound transactions itself, according to the specified propagation
- * behavior. It assumes that a separate, independent {@link Connection} can be obtained even during an ongoing
- * transaction.
- * <p>
- * Application code is required to retrieve the R2DBC Connection via
- * {@link ConnectionFactoryUtils#getConnection(ConnectionFactory)} instead of a standard R2DBC-style
- * {@link ConnectionFactory#create()} call. Spring classes such as {@link DatabaseClient} use this strategy implicitly.
- * If not used in combination with this transaction manager, the {@link ConnectionFactoryUtils} lookup strategy behaves
- * exactly like the native {@link ConnectionFactory} lookup; it can thus be used in a portable fashion.
- * <p>
- * Alternatively, you can allow application code to work with the standard R2DBC lookup pattern
- * {@link ConnectionFactory#create()}, for example for code that is not aware of Spring at all. In that case, define a
- * {@link TransactionAwareConnectionFactoryProxy} for your target {@link ConnectionFactory}, and pass that proxy
- * {@link ConnectionFactory} to your DAOs, which will automatically participate in Spring-managed transactions when
- * accessing it.
- * <p>
- * This transaction manager triggers flush callbacks on registered transaction synchronizations (if synchronization is
- * generally active), assuming resources operating on the underlying R2DBC {@link Connection}.

-/**
- * Implementation of {@link SmartConnectionFactory} that wraps a single R2DBC Connection which is not closed after use.
- * Obviously, this is not multi-threading capable.
- * <p>
- * Note that at shutdown, someone should close the underlying Connection via the {@code close()} method. Client code
- * will never call close on the Connection handle if it is SmartDataSource-aware (e.g. uses
- * {@link ConnectionFactoryUtils#releaseConnection(io.r2dbc.spi.Connection, ConnectionFactory)}).
- * <p>
- * If client code will call {@link Connection#close()} in the assumption of a pooled Connection, like when using
- * persistence tools, set "suppressClose" to "true". This will return a close-suppressing proxy instead of the physical
- * Connection.
- * <p>
- * This is primarily intended for testing. For example, it enables easy testing outside an application server, for code
- * that expects to work on a {@link ConnectionFactory}.

- * participate in Spring-managed transactions. Note that the transaction manager, for example
- * {@link R2dbcTransactionManager}, still needs to work with the underlying {@link ConnectionFactory}, <i>not</i> with
- * this proxy.
- * <p>
- * <b>Make sure that {@link TransactionAwareConnectionFactoryProxy} is the outermost {@link ConnectionFactory} of a
- * chain of {@link ConnectionFactory} proxies/adapters.</b> {@link TransactionAwareConnectionFactoryProxy} can delegate
- * either directly to the target connection pool or to some intermediary proxy/adapter.
- * <p>
- * Delegates to {@link ConnectionFactoryUtils} for automatically participating in thread-bound transactions, for example
- * managed by {@link R2dbcTransactionManager}. {@link #create()} calls and {@code close} calls on returned
- * {@link Connection} will behave properly within a transaction, i.e. always operate on the transactional Connection. If
- * not within a transaction, normal {@link ConnectionFactory} behavior applies.
- * <p>
- * This proxy allows data access code to work with the plain R2DBC API. However, if possible, use Spring's
- * {@link ConnectionFactoryUtils} or {@link DatabaseClient} to get transaction participation even without a proxy for
- * the target {@link ConnectionFactory}, avoiding the need to define such a proxy in the first place.
- * <p>
- * <b>NOTE:</b> This {@link ConnectionFactory} proxy needs to return wrapped {@link Connection}s (which implement the
- * {@link ConnectionProxy} interface) in order to handle close calls properly. Use {@link Wrapped#unwrap()} to retrieve
- * the native R2DBC Connection.

- * <p>
- * This class applies the following matching rules:
- * <ul>
- * <li>Try custom translation implemented by any subclass. Note that this class is concrete and is typically used
- * itself, in which case this rule doesn't apply.
- * <li>Apply error code matching. Error codes are obtained from the SQLErrorCodesFactory by default. This factory loads
- * a "sql-error-codes.xml" file from the class path, defining error code mappings for database names from database
- * meta-data.
- * <li>Fallback to a fallback translator. {@link SqlStateR2dbcExceptionTranslator} is the default fallback translator,
- * analyzing the exception's SQL state only.
- * </ul>
- * <p>
- * The configuration file named "sql-error-codes.xml" is by default read from the
- * {@code org.springframework.jdbc.support} package. It can be overridden through a file of the same name in the root of
- * the class path (e.g. in the "/WEB-INF/classes" directory), as long as the Spring JDBC package is loaded from the same
- * ClassLoader.

Subject: [PATCH 1472/2145] Support element conversion of array results.

This is achieved by passing the full availabe type information of the conversion target to the conversion service.

This broke a test which wasn't functional in the first place which becomes obvious when adding the proper assertion.

Closes #1046

Subject: [PATCH 1476/2145] Replaces java.sql.Types constants with
 java.sql.SQLType values.

java.sql.Types constants are int values and therefore make it tedious to read and debug the code.
SQLType values are mostly enum constants which are much nicer to use.

Subject: [PATCH 1478/2145] Polishing.

Rename "null handling" to "null precedence".
This is somewhat inconsistent with commons null handling, but more descriptive.

Minor formatting.

Subject: [PATCH 1480/2145] Introduced pessimistic locks for derived queries.

Methods which use the derive query functionality now can be annotated with `@Lock` to used a given `LockMode`. Right now there are two different modes `PESSIMISTIC_READ` and `PESSIMISTIC_WRITE`. Based on the dialect the right select is generated. For example for HSQLDB `Select ... FOR UPDATE`.

From 351ed47d7c9980d8099fd5215ff6f1d7ce20d053 Mon Sep 17 00:00:00 2001
From: Jens Schauder <jschauder@vmware.com>
Date: Wed, 9 Feb 2022 16:16:49 +0100
Subject: [PATCH 1481/2145] Polishing.

Refactored the unit tests to include a negative case and to separate the different scenarios tested.

Removed the default LockMode from the Lock annotation.
I have the feeling that most users will assume an exclusive Lock when none is specified, but also don't want to request stronger locks than required.

+Spring Data JDBC supports locking on derived query methods.
+To enable locking on a given derived query method inside a repository, you annotate it with `@Lock`.
+The required value of type `LockMode` offers two values: `PESSIMISTIC_READ` which guarantees that the data you are reading doesn't get modified and `PESSIMISTIC_WRITE` which obtains a lock to modify the data.
+Some databases do not make this distinction.
+In that cases both modes are equivalent of `PESSIMISTIC_WRITE`.

-
-== Running CI tasks locally
-
-Since this pipeline is purely Docker-based, it's easy to:
-
-* Debug what went wrong on your local machine.
-* Test out a a tweak to your `test.sh` script before sending it out.
-* Experiment against a new image before submitting your pull request.
-
-All of these use cases are great reasons to essentially run what the CI server does on your local machine.
-
-IMPORTANT: To do this you must have Docker installed on your machine.
-
-1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-r2dbc-github  -v /usr/bin/docker:/usr/bin/docker -v /var/run/docker.sock:/var/run/docker.sock adoptopenjdk/openjdk8:latest /bin/bash`
-+
-This will launch the Docker image and mount your source code at `spring-data-r2dbc-github`.
-+
-2. `cd spring-data-r2dbc-github`
-+
-Next, test everything from inside the container:
-+
-3. `./mvnw -Pci,all-dbs clean dependency:list test -Dsort -B` (or whatever test configuration you must use)
-
-Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
-
-NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-

-= Spring Data R2DBC image:https://jenkins.spring.io/buildStatus/icon?job=spring-data-r2dbc%2Fmain&subject=Build[link=https://jenkins.spring.io/view/SpringData/job/spring-data-r2dbc/] https://gitter.im/spring-projects/spring-data[image:https://badges.gitter.im/spring-projects/spring-data.svg[Gitter]]
-
-The primary goal of the https://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use data access technologies. *Spring Data R2DBC* offers the popular Repository abstraction based on https://r2dbc.io[R2DBC].
-
-R2DBC is the abbreviation for https://github.com/r2dbc/[Reactive Relational Database Connectivity], an incubator to integrate relational databases using a reactive driver.
-
-== This is NOT an ORM
-
-Spring Data R2DBC aims at being conceptually easy. In order to achieve this it does NOT offer caching, lazy loading, write behind or many other features of ORM frameworks. This makes Spring Data R2DBC a simple, limited, opinionated object mapper.
-
-== Features
-
-* Spring configuration support using Java based `@Configuration` classes.
-* Annotation based mapping metadata.
-* Automatic implementation of Repository interfaces including support.
-* Support for Reactive Transactions
-* Schema and data initialization utilities.
-
-== Code of Conduct
-
-This project is governed by the https://github.com/spring-projects/.github/blob/e3cc2ff230d8f1dca06535aa6b5a4a23815861d4/CODE_OF_CONDUCT.md[Spring Code of Conduct]. By participating, you are expected to uphold this code of conduct. Please report unacceptable behavior to spring-code-of-conduct@pivotal.io.

-== Getting Help
-
-Having trouble with Spring Data? We’d love to help!
-
-* Check the
-https://docs.spring.io/spring-data/r2dbc/docs/1.0.x/reference/html/#reference[reference documentation], and https://docs.spring.io/spring-data/r2dbc/docs/1.0.x/api/[Javadocs].
-* Learn the Spring basics – Spring Data builds on Spring Framework, check the https://spring.io[spring.io] web-site for a wealth of reference documentation.
-If you are just starting out with Spring, try one of the https://spring.io/guides[guides].
-* If you are upgrading, check out the https://docs.spring.io/spring-data/r2dbc/docs/current/changelog.txt[changelog] for "`new and noteworthy`" features.
-* Ask a question - we monitor https://stackoverflow.com[stackoverflow.com] for questions tagged with https://stackoverflow.com/tags/spring-data-r2dbc[`spring-data-r2dbc`].
-* Report bugs with Spring Data R2DBC at https://github.com/spring-projects/spring-data-r2dbc/issues[github.com/spring-projects/spring-data-r2dbc/issues].
-
-== Reporting Issues
-
-Spring Data uses GitHub as issue tracking system to record bugs and feature requests. If you want to raise an issue, please follow the recommendations below:
-
-* Before you log a bug, please search the
-https://github.com/spring-projects/spring-data-r2dbc/issues[issue tracker] to see if someone has already reported the problem.
-* If the issue does not already exist, https://github.com/spring-projects/spring-data-r2dbc/issues/new[create a new issue].
-* Please provide as much information as possible with the issue report, we like to know the version of Spring Data that you are using and JVM version.
-* If you need to paste code, or include a stack trace use Markdown +++```+++ escapes before and after your text.
-* If possible try to create a test-case or project that replicates the issue. Attach a link to your code or a compressed file containing your code.
-
-== Building from Source
-
-You don’t need to build from source to use Spring Data (binaries in https://repo.spring.io[repo.spring.io]), but if you want to try out the latest and greatest, Spring Data can be easily built with the https://github.com/takari/maven-wrapper[maven wrapper].
-You also need JDK 1.8.
-
-[source,bash]
-----
- $ ./mvnw clean install
-----
-
-If you want to build with the regular `mvn` command, you will need https://maven.apache.org/run-maven/index.html[Maven v3.5.0 or above].
-
-_Also see link:CONTRIBUTING.adoc[CONTRIBUTING.adoc] if you wish to submit pull requests, and in particular please sign the https://cla.pivotal.io/sign/spring[Contributor’s Agreement] before your first non-trivial change._
-
-=== Building reference documentation
-
-Building the documentation builds also the project without running tests.
-
-[source,bash]
-----
- $ ./mvnw clean install -Pdistribute
-----
-
-The generated documentation is available from `target/site/reference/html/index.html`.
-
-== Examples
-
-* https://github.com/spring-projects/spring-data-examples/[Spring Data Examples] contains example projects that explain specific features in more detail.

Subject: [PATCH 1493/2145] `StringBuilder` can be replaced with String
 concatenation.

In this case the usage of `StringBuilder` has no additional benefit, since it is not inside a loop where the JVM may have problems detecting String concatenation that can be optimized. The usage of "simple" String concatenation makes the code more readable and the code will be automatically optimised by the compiler.

There were few explicit `toString()` calls that are not needed, since `toString()` will be called by default.

Subject: [PATCH 1499/2145] Introduced pessimistic locks for derived queries.

Methods which use the derive query functionality now can be annotated with `@Lock` to used a given `LockMode`. Right now there are two different modes `PESSIMISTIC_READ` and `PESSIMISTIC_WRITE`. Based on the dialect the right select is generated. For example for H2 `Select ... FOR UPDATE`.

Closes spring-projects/spring-data-jdbc#1041
See #643,

Subject: [PATCH 1506/2145] Introduced `queryLookupStrategy` to
 `EnableJdbcRepositories`.

Added the missing functionality that is found in the documentation of spring-data-jdbc, but was not present in the code as functionality. Users can not choose between various QueryLookupStrategies.

Closes #1043

Subject: [PATCH 1509/2145] Batch inserts of referenced entities.

Insert for entities of same type within an aggregate get inserted using JDBC batch operations when possible.

Inserts are supported when no id needs to be generated by the database or if the Dialect supports generation of ids in batch operations.

Subject: [PATCH 1525/2145] Polishing.

This change extracts entity modifying behaviour into separate methods, so it doesn't appear as an unexpected side effect of the creation of aggregate changes.

Also some formatting.

Subject: [PATCH 1526/2145] Fix assemble table alias for embedded entity with
 empty prefix and reference.

Table alias for embedded entity use prefix value from Embedded annotation. But default value for prefix is empty string. If try to create SqlIdentifier for empty string it throw exception. To avoid this behavior, if prefix is an empty string, property name for embedded entity is taken instead.

From 508791b7df3f8a637295d663aca982487399acd9 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1529/2145] Capture execution results for update db actions to
 fix root references with immutably typed ids.

+ Added #getIdValueSource to DbAction.WithEntity since it now applies to all such DbAction.
+ Removed DbAction.WithGeneratedId in favor of DbAction.WithEntity where it was used.

Removes unused DbAction.Update.

Passes the root from BeforeSaveCallback through to InsertRoot,UpdateRoot
actions.

+ Isolate aggregate change #getEntity #setEntity behaviors into a new
interface for "save" changes.
+ Extract #setEntity from DbAction.WithEntity to a new DbAction interface
just for root actions.
+ JdbcAggregateChangeExecutionContext#populateIdsIfNecessary returns the root entity
from DbAction.InsertRoot or DbAction.UpdateRoot regardless of the immutability of
its @Id property.

Closes #1199
Closes #1201
Original pull request #1208

Subject: [PATCH 1544/2145] Downgrade to mybatis-spring 2.0.7.

Since at the time of the release only snapshot releases of mybatis-spring 2.1 are available we decided to downgrade to 2.0.7. for the release.

Unfortunately that release is not compatible with the current milestone of Spring Framework and therefore the MyBatis integration is broken.

If you want to use MyBatis with this release, manually add a dependency to mybatis-spring 2.1.0-SNAPSHOT.

Closes #1245

Subject: [PATCH 1552/2145] Update @Query argument conversion to handle
 Collection<Enum>.

+ Copy logic from QueryMapper#convertToJdbcValue to resolve Iterable
  arguments on findBy* query methods to resolve the same for @Query.
+ Use parameter ResolvableType instead of Class to retain generics info.

Original pull request #1226
Closes #1212

Subject: [PATCH 1554/2145] Support readonly properties for references.

The `@ReadOnlyProperty` annotation is now honoured for references to entities or collections of entities.

For tables mapped to such annotated references, no insert, delete or update statements will be created.
The user has to maintain that data through some other means.
These could be triggers or external process or `ON DELETE CASCADE` configuration in the database schema.

Closes #1249

 Spring Data JDBC uses the ID to identify entities.
 The ID of an entity must be annotated with Spring Data's https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
 
-When your data base has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
+When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
 
 One important constraint is that, after saving an entity, the entity must not be new any more.
 Note that whether an entity is new is part of the entity's state.
 With auto-increment columns, this happens automatically, because the ID gets set by Spring Data with the value from the ID column.
 If you are not using auto-increment columns, you can use a `BeforeConvert` listener, which sets the ID of the entity (covered later in this document).
 
+[[jdbc.entity-persistence.read-only-properties]]
+=== Read Only Properties
+
+Attributes annotated with `@ReadOnlyProperty` will not be written to the database by Spring Data JDBC, but they will be read when an entity gets loaded.
+
+Spring Data JDBC will not automatically reload an entity after writing it.
+Therefore, you have to reload it explicitly if you want to see data that was generated in the database for such columns.
+
+If the annotated attribute is an entity or collection of entities, it is represented by one or more separate rows in separate tables.
+Spring Data JDBC will not perform any insert, delete or update for these rows.

+ Update #populateIdsIfNecessary return type from T to List<T>

Pull out an abstract BatchWithValue class from InsertBatch to use it for batching root inserts as well.

Rename InsertBatch to BatchInsert
Rename AggregateChangeWithRoot to RootAggregateChange.

Subject: [PATCH 1575/2145] Upgrade Oracle JDBC driver to the latest working
 version.

Turns out the latest working version for Spring Data JDBC is ojdbc8 19.15.0.0.1. ojdbc11 or later versions of ojdbc8 contain a bug that breaks batching.

Since Spring Data R2DBC only uses the driver for testing. fFor it the latest working version is ojdbc11 21.6.0.0.1.

+The term, "`reactive`", refers to programming models that are built around reacting to change, availability, and processability-network components reacting to I/O events, UI controllers reacting to mouse events, resources being made available, and others.
 In that sense, non-blocking is reactive, because, instead of being blocked, we are now in the mode of reacting to notifications as operations complete or data becomes available.
 
 There is also another important mechanism that we on the Spring team associate with reactive, and that is non-blocking back pressure.

+[[query-by-example.running]]
+== Running an Example
+
+In Spring Data JDBC, you can use Query by Example with Repositories, as shown in the following example:
+
+.Query by Example using a Repository
+====
+[source, java]
+----
+public interface PersonRepository
+        extends CrudRepository<Person, String>,
+        QueryByExampleExecutor<Person> { … }
+
+public class PersonService {
+
+  @Autowired PersonRepository personRepository;
+
+  public List<Person> findPeople(Person probe) {
+    return personRepository.findAll(Example.of(probe));
+  }
+}
+----
+====
+
+NOTE: Currently, only `SingularAttribute` properties can be used for property matching.
+
+The property specifier accepts property names (such as `firstname` and `lastname`). You can navigate by chaining properties together with dots (`address.city`). You can also tune it with matching options and case sensitivity.
+
+The following table shows the various `StringMatcher` options that you can use and the result of using them on a field named `firstname`:
+
+[cols="1,2", options="header"]
+.`StringMatcher` options
+|===
+| Matching
+| Logical result
+
+| `DEFAULT` (case-sensitive)
+| `firstname = ?0`
+
+| `DEFAULT` (case-insensitive)
+| `LOWER(firstname) = LOWER(?0)`
+
+| `EXACT`  (case-sensitive)

From aad40a32b0dcb12efab1d700b554118e039472cb Mon Sep 17 00:00:00 2001
From: Jens Schauder <jschauder@vmware.com>
Date: Mon, 11 Jul 2022 12:48:45 +0200
Subject: [PATCH 1593/2145] Polishing.

Added `@since` comments for new methods and classes.
General formatting and code style tweaking.
Github references for new tests added.
Fixes for integration tests with various databases:
- Not all stores support submillisecond precision for Instant.
- Count for exists query doesn't work for all databases, nor does `LEAST(COUNT(1), 1)`
- MariaDB defaults timestamp columns to the current time.
- Ordering was applied twice.
- DATETIME in SqlServer has a most peculiar preceision. We switch to DATETIME2.

Reuse H2 dialect settings in R2DBC-specific H2 dialect.
Refactor ArrayColumns support classes, into toplevel-types. Let R2DBC H2 sublass the relational H2Dialect to decouple from Postgres.

Subject: [PATCH 1608/2145] Avoid duplicate selection of columns.

When the key column of a MappedCollection is also present in the contained entity that column got select twice.
We now check if the column already gets selected before adding it to the selection.

This only works properly if the column names derived for the entity property and the key column match exactly, which might require use of a `@Column` annotation depending on the used NamingStrategy.

From e246cc4f598d7483bddac33de615c359a723fb04 Mon Sep 17 00:00:00 2001
From: Mark Paluch <mpaluch@vmware.com>

Subject: [PATCH 1611/2145] Fix parameter binding of reused named parameters
 using anonymous bind markers.

We now properly bind values for reused named parameters correctly when using anonymous bind markers (e.g. ? for MySQL). Previously, the subsequent usages of named parameters especially with IN parameters were left not bound.

Closes #1306

Subject: [PATCH 1612/2145] Retain element ordering in `AfterConvertCallback`s.

We now use concatMap on result Fluxes to retain the object order. Previously, we used flatMap on a flux that has led to changes in element ordering.

Closes #1307

Subject: [PATCH 1613/2145] Fix COUNT/EXISTS projections for entities without
 an identifier.

We now issue a COUNT(1) respective SELECT 1 for COUNT queries and EXISTS queries for entities that do not specify an identifier.

Previously these query projections could fail because of empty select lists.

Subject: [PATCH 1616/2145] Correct behavior of NOOP deletes to match the
 specification in `CrudRepository`.

Delete operations that receive a version attribute throw an `OptimisticFailureException` when they delete zero rows.
Otherwise, the NOOP delete gets silently ignored.

Note that save operations that are determined to be an update because the aggregate is not new will still throw an `IncorrectUpdateSemanticsDataAccessException` if they fail to update any row.
This is somewhat asymmetric to the delete-behaviour.
But with a delete the intended result is achieved: the aggregate is gone from the database.
For save operations the intended result is not achieved, hence the exception.

Closes #1313
Original pull request: #1314.

Subject: [PATCH 1617/2145] Reenable quoting for SqlServerDialect.

Quoting is important since it allows use of keywords as names.
We do not change the letter casing.
In a default setup the database does not care since it is case-insensitive.
If configured to be case-sensitive it makes sense to pass on what ever letter casing there is, since you seem to care.

Closes #1216
See #914

From bf356f561daccd254b0c64ff93c5ef7d10db1d23 Mon Sep 17 00:00:00 2001
From: Jens Schauder <jschauder@vmware.com>
Date: Thu, 8 Sep 2022 15:31:17 +0200
Subject: [PATCH 1619/2145] Clarify documentation for `@Modifying`.

Modifying queries are executed directly against the database.
No events or callbacks get called.
Therefore also fields with auditing annotations do not get updated if they don't get updated in the annotated query.

Closes #970

List<User> findUsersByCustomersFirstname(@Param("customer") Customer customer);
```

Closes #619
Original pull request #229

Subject: [PATCH 1631/2145] Add support for factory methods.

R2DBC now supports the use of factory methods for entity creation.
Spring Data JDBC already does so via f326897950

Simply annotate a static factory method on your entity class with `@PersistenceCreator`.

Closes #1346
See https://github.com/spring-projects/spring-data-commons/issues/2476
See https://github.com/spring-projects/spring-data-relational/commit/f32689795041d807191b577b8f8f7b549ec7425a

Subject: [PATCH 1637/2145] Introduce `@InsertOnlyProperty`.

You may now annotate properties of the aggregate root with `@InsertOnlyProperty`.
Properties annotated in such way will be written to the database only during insert operations, but they will not be updated afterwards.

Closes #637

Subject: [PATCH 1639/2145] The back reference generation is now configurable.

The default version is the behavior that existed so far:
The back reference is the table name as generated by the `NamingStrategy` without taking `@Table` annotations into account.

The new alternative is to take `@Table` into account.

The behavior can be configured by setting the `foreignKeyNaming` property on the `RelationalMappingContext`.

Closes #1161
Closes #1147
Original pull request: #1324.

 .Declaring and setting an `AggregateReference`
 ====

From d7f2a27ee9140a4777cf70493ec404a810f9ddc7 Mon Sep 17 00:00:00 2001
From: Jens Schauder <jschauder@vmware.com>
Date: Fri, 2 Sep 2022 11:41:04 +0200
Subject: [PATCH 1640/2145] Revised default behaviour for back reference
 naming.

The new default is to take `@Table` annotations into account.

The behaviour can be configured by setting the `foreignKeyNaming` property on the `RelationalMappingContext`.

Closes #1162
See #1147
Original pull request: #1324.

+By default, the name of the foreign key column is the table name of the referencing entity.
 
-Alternatively you may choose to have them named by the actual table name of the referencing entity.
-You activate this behaviour by calling `setForeignKeyNaming(ForeignKeyNaming.APPLY_RENAMING)` on the `RelationalMappingContext`.
+Alternatively you may choose to have them named by the entity name of the referencing entity ignoreing `@Table` annotations.
+You activate this behaviour by calling `setForeignKeyNaming(ForeignKeyNaming.IGNORE_RENAMING)` on the `RelationalMappingContext`.
 
 For `List` and `Map` references an additional column is required for holding the list index or map key. It is based on the foreign key column with an additional `_KEY` suffix.

Subject: [PATCH 1642/2145] Polishing.

Do not expose setForeignKeyNaming methods on NamingStrategy to make less assumptions about how a naming strategy gets implemented. Provide getRequiredLeafEntity method on PersistentPropertyPathExtension to reduce null and state assertion checks.

Refine getTableName/getQualifiedTableName approach to reduce API surface and avoid deprecations.

Subject: [PATCH 1645/2145] Support `SimpleFunction` and `SimpleExpression` in
 order by expression.

This allows ordering by functions like:

    ORDER BY GREATEST(table1.created_at, table2.created_at) ASC

or by arbitrary SQL snippets

    orderBy(OrderByField.from(Expressions.just("1")).asc()) => ORDER BY 1 ASC

Subject: [PATCH 1665/2145] Fix broken join conditions with InlineQuery.

Before this fix, whenever a column of an inline query was rendered the `InlineQuery` and all its children were visited, resulting in spurious output.
This is no prevented by injecting a NoopVisitor.

Subject: [PATCH 1742/2145] Introduce SqlSort.

SqlSort allows the specification of unsafe order-by-expressions.
Order-by-expressions that are not declared unsafe are only accepted when they
either match a property or consist only of digits, letters, underscore, dot, or parentheses.

 Closes #1507

This also deprecates org.springframework.data.r2dbc.query.QueryMapper.getMappedObject(Sort, RelationalPersistentEntity<?>).
It was only used in tests and translates an Order into another Order, which sounds wrong.

Closes #1512

Subject: [PATCH 1752/2145] Add SpEL support for `@Table` and `@Column`.

If SpEl expressions are specified in the `@Table` or `@Column` annotation, they will be evaluated and the output will be sanitized to prevent SQL Injections.

The default sanitization only allows digits, alphabetic characters, and _ character. (i.e. [0-9, a-z, A-Z, _])

Subject: [PATCH 1753/2145] Polishing.

Reuse existing EvaluationContextProvider infrastructure and static parser/parser context instances. Parse expressions early. Update Javadoc to reflect SpEL support.

Reformat code to use tabs instead of spaces. Rename types for consistency. Rename SpelExpressionResultSanitizer to SqlIdentifierSanitizer to express its intended usage.

Eagerly initialize entities where applicable. Simplify code.

Subject: [PATCH 1756/2145] Add support for schema creation using Liquibase.

We now support schema creation and schema migration by generating Liquibase changesets from mapped entities. We also support evolution of schema by comparing existing tables with mapped entities to compute differential changesets.

Closes #756
Original pull request: #1520

Subject: [PATCH 1757/2145] Polishing.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reformat code, switch to tabs. Accept property in DatabaseTypeMapping to provide more context to the type mapping component.

Rename LiquibaseChangeSetGenerator to …Writer as we're writing a changeset and computing the contents is a consequence of writing a changeset. Refine naming to express what we're actually doing.

Introduce setters for enhanced configuration of predicates. Reduce visibility of types to avoid unwanted public API where public access is not needed.

Remove usused code, move methods around for improved grouping of code.

Rename package to schema as the schema is being created and updated and not generated. Rename …Model classes to just their name as types are package-private and not visible externally. Refactor SchemaDiff to Java record.

Use different overloads to write schema changes to avoid LiquibaseException leaking into cases where no diff is being used. Introduce SchemaFilter to filter unwanted mapped entities.

Move code to JDBC module. Introduce comparator strategy to customize how table and column names are compared.

See #756

+[[jdbc.schema]]
+= Schema Creation
+
+When working with SQL databases, the schema is an essential part.
+Spring Data JDBC supports a wide range of schema options yet when starting with a domain model it can be challenging to come up with an initial domain model.
+To assist you with a code-first approach, Spring Data JDBC ships with an integration to create database change sets using https://www.liquibase.org/[Liquibase].
+
+Consider the following domain entity:
+
+[source,java]
+----
+@Table
+class Person {
+  @Id long id;
+  String firstName;
+  String lastName;
+  LocalDate birthday;
+  boolean active;
+}
+----
+
+Rendering the initial ChangeSet through the following code:
+
+[source,java]
+----
+
+RelationalMappingContext context = … // The context contains the Person entity, ideally initialized through initialEntitySet
+LiquibaseChangeSetWriter writer = new LiquibaseChangeSetWriter(context);
+
+writer.writeChangeSet(new FileSystemResource(new File(…)));
+----
+
+yields the following change log:
+
+[source,yaml]
+----
+databaseChangeLog:

+    changes:

+        columns:
+        - column:
+            autoIncrement: true
+            constraints:
+              nullable: false
+              primaryKey: true
+            name: id
+            type: BIGINT
+        - column:
+            constraints:
+              nullable: true
+            name: first_name
+            type: VARCHAR(255 BYTE)
+        - column:
+            constraints:
+              nullable: true
+            name: last_name
+            type: VARCHAR(255 BYTE)
+        - column:
+            constraints:
+              nullable: true
+            name: birthday
+            type: DATE
+        - column:
+            constraints:
+              nullable: false
+            name: active
+            type: TINYINT
+        tableName: person
+----
+
+Column types are computed from an object implementing the `SqlTypeMapping` strategy interface.
+Nullability is inferred from the type and set to `false` if a property type use primitive Java types.
+
+Schema support can assist you throughout the application development lifecycle.
+In differential mode, you provide an existing Liquibase `Database` to the schema writer instance and the schema writer compares existing tables to mapped entities and derives from the difference which tables and columns to create/to drop.
+By default, no tables and no columns are dropped unless you configure `dropTableFilter` and `dropColumnFilter`.
+Both filter predicate provide the table name respective column name so your code can computer which tables and columns can be dropped.
+
+[source,java]
+----
+writer.setDropTableFilter(tableName -> …);
+writer.setDropColumnFilter((tableName, columnName) -> …);
+----
+
+NOTE: Schema support can only identify additions and removals in the sense of removing tables/columns that are not mapped or adding columns that do not exist in the database.
+Columns cannot be renamed nor data cannot be migrated because entity mapping does not provide details of how the schema has evolved.

Subject: [PATCH 1767/2145] Updating Oracle version to Oracle Free 23.

The new image is configured as compatible with the old image, which it actually isn't.
The default database names are different, so we also set a database name that is different both from the one used by TestContainers as default and the one used by the Docker image.
If the TestContainers default is used the database is not found, because the image just creates the default one and the name doesn't mach.
If the Docker image default is used, the image creates its default database and then tries to create it again, which fails.

These workarounds may be removed once TestContainers properly supports the new image.

Closing #1528

Subject: [PATCH 1782/2145] Introduce AggregatePath.

AggregatePath replaces PersistentPropertyPathExtension.
It gets created and cached by the RelationalMappingContext, which should be more efficient and certainly looks nicer.

Subject: [PATCH 1786/2145] Enable Single Query Loading for simple aggregates.

Single Query Loading loads as the name suggests complete aggregates using a single select.
While the ultimate goal is to support this for all aggregates, this commit enables it only for simple aggregate and also only for some operations.
A simple aggregate is an aggregate that only reference up to one other entity and does not have embedded entities.
The supported operations are those available via `CrudRepository`: `findAll`, `findById`, and `findAllByIds`.

Single Query Loading does NOT work with the supported in memory databases H2 and HSQLDB, since these do not properly support windowing functions, which are essential for Single Query Loading.

To turn on Single Query Loading call `RelationalMappingContext.setSingleQueryLoadingEnabled(true)`.

Closes #1446
See #1450
See #1445
Original pull request: #1572

+[[jdbc.loading-aggregates]]
+== Loading Aggregates
+Spring Data JDBC offers two ways how it can load aggregates.
+The traditional and before version 3.2 the only way is really simple:
+Each query loads the aggregate roots, independently if the query is based on a `CrudRepository` method, a derived query or a annotated query.
+If the aggregate root references other entities those are loaded with separate statements.
+
+Spring Data JDBC now allows the use of _Single Query Loading_.
+With this an arbitrary number of aggregates can be fully loaded with a single SQL query.
+This should be significant more efficient, especially for complex aggregates, consisting of many entities.
+
+Currently this feature is very restricted.
+
+1. It only works for aggregates that only reference one entity collection. The plan is to remove this constraint in the future.
+
+2. The aggregate must also not use `AggregateReference` or embedded entities. The plan is to remove this constraint in the future.
+
+3. The database dialect must support it. Of the dialects provided by Spring Data JDBC all but H2 and HSQL support this. H2 and HSQL don't support analytic functions (aka windowing functions).
+
+4. It only works for the find methods in `CrudRepository`, not for derived queries and not for annotated queries. The plan is to remove this constraint in the future.
+
+5. Single Query Loading needs to be enabled in the `JdbcMappingContext`, by calling `setSingleQueryLoadingEnabled(true)`
+
+Note: Single Query Loading is to be considered experimental. We appreciate feedback on how it works for you.
+
+Note:Single Query Loading can be abbreviated as SQL, but we highly discourage that since confusion with Structured Query Language is almost guaranteed.

From d9b548815c116ec43e031b2a08a86f9592ecf560 Mon Sep 17 00:00:00 2001
From: Mark Paluch <mpaluch@vmware.com>
Date: Wed, 9 Aug 2023 10:27:19 +0200
Subject: [PATCH 1787/2145] Polishing.

Extract Single Query Loading branching to SingleQueryFallbackDataAccessStrategy. Inline AggregateReaderFactory into SingleQueryDataAccessStrategy. Move CachingSqlGenerator to AggregateReader as caching root.

Introduce DataAccessStrategyFactory to encapsulate configuration.

Fix Javadoc tag ordering. Remove superfluous MappingContext parameters when Converter is available. Simplify code. Reformat code.

Reorder Functions methods. Tweak Javadoc, move composite function into SingleQuerySqlGenerator.

-= Preface
-
-The Spring Data R2DBC project applies core Spring concepts to the development of solutions that use the https://r2dbc.io[R2DBC] drivers for relational databases.
-We provide a `DatabaseClient` as a high-level abstraction for storing and querying rows.
-
-This document is the reference guide for Spring Data - R2DBC Support.
-It explains R2DBC module concepts and semantics.
-
-This section provides some basic introduction to Spring and databases.
-[[get-started:first-steps:spring]]
-== Learning Spring
-
-Spring Data uses Spring framework's {spring-framework-ref}/core.html[core] functionality, including:
-
-* {spring-framework-ref}/core.html#beans[IoC] container
-* {spring-framework-ref}/core.html#validation[type conversion system]
-* {spring-framework-ref}/core.html#expressions[expression language]
-* {spring-framework-ref}/integration.html#jmx[JMX integration]
-* {spring-framework-ref}/data-access.html#dao-exceptions[DAO exception hierarchy].
-
-While you need not know the Spring APIs, understanding the concepts behind them is important.
-At a minimum, the idea behind Inversion of Control (IoC) should be familiar, and you should be familiar with whatever IoC container you choose to use.
-
-You can use the core functionality of the R2DBC support directly, with no need to invoke the IoC services of the Spring Container.
-This is much like `JdbcTemplate`, which can be used "`standalone`" without any other services of the Spring container.
-To use all the features of Spring Data R2DBC, such as the repository support, you need to configure some parts of the library to use Spring.
-
-To learn more about Spring, refer to the comprehensive documentation that explains the Spring Framework in detail.
-There are a lot of articles, blog entries, and books on the subject.
-See the Spring framework https://spring.io/docs[home page] for more information.
-
-[[get-started:first-steps:what]]
-== What is R2DBC?
-
-https://r2dbc.io[R2DBC] is the acronym for Reactive Relational Database Connectivity.
-R2DBC is an API specification initiative that declares a reactive API to be implemented by driver vendors to access their relational databases.
-
-Part of the answer as to why R2DBC was created is the need for a non-blocking application stack to handle concurrency with a small number of threads and scale with fewer hardware resources.
-This need cannot be satisfied by reusing standardized relational database access APIs -- namely JDBC –- as JDBC is a fully blocking API.
-Attempts to compensate for blocking behavior with a `ThreadPool` are of limited use.
-
-The other part of the answer is that most applications use a relational database to store their data.
-While several NoSQL database vendors provide reactive database clients for their databases, migration to NoSQL is not an option for most projects.
-This was the motivation for a new common API to serve as a foundation for any non-blocking database driver.
-While the open source ecosystem hosts various non-blocking relational database driver implementations, each client comes with a vendor-specific API, so a generic layer on top of these libraries is not possible.
-
-[[get-started:first-steps:reactive]]
-== What is Reactive?
-
-The term, "`reactive`", refers to programming models that are built around reacting to change, availability, and processability-network components reacting to I/O events, UI controllers reacting to mouse events, resources being made available, and others.
-In that sense, non-blocking is reactive, because, instead of being blocked, we are now in the mode of reacting to notifications as operations complete or data becomes available.
-
-There is also another important mechanism that we on the Spring team associate with reactive, and that is non-blocking back pressure.
-In synchronous, imperative code, blocking calls serve as a natural form of back pressure that forces the caller to wait.
-In non-blocking code, it becomes essential to control the rate of events so that a fast producer does not overwhelm its destination.
-
-https://github.com/reactive-streams/reactive-streams-jvm/blob/v{reactiveStreamsVersion}/README.md#specification[Reactive Streams is a small spec] (also https://docs.oracle.com/javase/9/docs/api/java/util/concurrent/Flow.html[adopted in Java 9]) that defines the interaction between asynchronous components with back pressure.
-For example, a data repository (acting as a {reactiveStreamsJavadoc}/org/reactivestreams/Publisher.html[`Publisher`]) can produce data that an HTTP server (acting as a {reactiveStreamsJavadoc}/org/reactivestreams/Subscriber.html`[`Subscriber`]) can then write to the response.
-The main purpose of Reactive Streams is to let the subscriber control how quickly or how slowly the publisher produces data.
-
-[[get-started:first-steps:reactive-api]]
-== Reactive API
-
-Reactive Streams plays an important role for interoperability.It is of interest to libraries and infrastructure components but less useful as an application API, because it is too low-level.
-Applications need a higher-level and richer, functional API to compose async logic —- similar to the Java 8 Stream API but not only for tables.
-This is the role that reactive libraries play.
-
-https://github.com/reactor/reactor[Project Reactor] is the reactive library of choice for Spring Data R2DBC.
-It provides the https://projectreactor.io/docs/core/release/api/reactor/core/publisher/Mono.html[`Mono`] and https://projectreactor.io/docs/core/release/api/reactor/core/publisher/Flux.html[`Flux`] API types to work on data sequences of `0..1` (`Mono`) and `0..N` (`Flux`) through a rich set of operators aligned with the ReactiveX vocabulary of operators.
-Reactor is a Reactive Streams library, and, therefore, all of its operators support non-blocking back pressure.
-Reactor has a strong focus on server-side Java. It is developed in close collaboration with Spring.
-
-Spring Data R2DBC requires Project Reactor as a core dependency, but it is interoperable with other reactive libraries through the  Reactive Streams specification.
-As a general rule, a Spring Data R2DBC repository accepts a plain `Publisher` as input, adapts it to a Reactor type internally, uses that, and returns either a `Mono` or a `Flux` as output.
-So, you can pass any `Publisher` as input and apply operations on the output, but you need to adapt the output for use with another reactive library.
-Whenever feasible, Spring Data adapts transparently to the use of RxJava or another reactive library.

-= R2DBC Repositories
-
-[[r2dbc.repositories.intro]]
-This chapter points out the specialties for repository support for R2DBC.
-This chapter builds on the core repository support explained in <<repositories>>.
-Before reading this chapter, you should have a sound understanding of the basic concepts explained there.
-
-[[r2dbc.repositories.usage]]
-== Usage
-
-To access domain entities stored in a relational database, you can use our sophisticated repository support that eases implementation quite significantly.
-To do so, create an interface for your repository.
-Consider the following `Person` class:
-
-.Sample Person entity
-====
-[source,java]
-----
-public class Person {
-
-  @Id
-  private Long id;
-  private String firstname;
-  private String lastname;
-
-  // … getters and setters omitted
-}
-----
-====
-
-The following example shows a repository interface for the preceding `Person` class:
-
-.Basic repository interface to persist Person entities
-====
-[source,java]
-----
-public interface PersonRepository extends ReactiveCrudRepository<Person, Long> {
-
-  // additional custom query methods go here
-}
-----
-====
-
-To configure R2DBC repositories, you can use the `@EnableR2dbcRepositories` annotation.
-If no base package is configured, the infrastructure scans the package of the annotated configuration class.
-The following example shows how to use Java configuration for a repository:
-
-.Java configuration for repositories
-====
-[source,java]
-----
-@Configuration
-@EnableR2dbcRepositories
-class ApplicationConfig extends AbstractR2dbcConfiguration {
-
-  @Override
-  public ConnectionFactory connectionFactory() {
-    return …
-  }
-}
-----
-====
-
-Because our domain repository extends `ReactiveCrudRepository`, it provides you with reactive CRUD operations to access the entities.
-On top of `ReactiveCrudRepository`, there is also `ReactiveSortingRepository`, which adds additional sorting functionality similar to that of `PagingAndSortingRepository`.
-Working with the repository instance is merely a matter of dependency injecting it into a client.
-Consequently, you can retrieve all `Person` objects with the following code:
-
-.Paging access to Person entities
-====
-[source,java,indent=0]
-----
-include::../{example-root}/PersonRepositoryTests.java[tags=class]
-----
-====
-
-The preceding example creates an application context with Spring's unit test support, which performs annotation-based dependency injection into test cases.
-Inside the test method, we use the repository to query the database.
-We use `StepVerifier` as a test aid to verify our expectations against the results.
-
-[[r2dbc.repositories.queries]]
-== Query Methods
-
-Most of the data access operations you usually trigger on a repository result in a query being run against the databases.
-Defining such a query is a matter of declaring a method on the repository interface, as the following example shows:
-
-.PersonRepository with query methods
-====
-[source,java]
-----
-interface ReactivePersonRepository extends ReactiveSortingRepository<Person, Long> {
-
-  Flux<Person> findByFirstname(String firstname);                                   <1>
-
-  Flux<Person> findByFirstname(Publisher<String> firstname);                        <2>
-
-  Flux<Person> findByFirstnameOrderByLastname(String firstname, Pageable pageable); <3>
-
-  Mono<Person> findByFirstnameAndLastname(String firstname, String lastname);       <4>
-
-  Mono<Person> findFirstByLastname(String lastname);                                <5>
-
-  @Query("SELECT * FROM person WHERE lastname = :lastname")
-  Flux<Person> findByLastname(String lastname);                                     <6>
-
-  @Query("SELECT firstname, lastname FROM person WHERE lastname = $1")
-  Mono<Person> findFirstByLastname(String lastname);                                <7>
-}
-----
-<1> The method shows a query for all people with the given `firstname`. The query is derived by parsing the method name for constraints that can be concatenated with `And` and `Or`. Thus, the method name results in a query expression of `SELECT … FROM person WHERE firstname = :firstname`.
-<2> The method shows a query for all people with the given `firstname` once the `firstname` is emitted by the given `Publisher`.
-<3> Use `Pageable` to pass offset and sorting parameters to the database.
-<4> Find a single entity for the given criteria. It completes with `IncorrectResultSizeDataAccessException` on non-unique results.
-<5> Unless <4>, the first entity is always emitted even if the query yields more result rows.
-<6> The `findByLastname` method shows a query for all people with the given last name.
-<7> A query for a single `Person` entity projecting only `firstname` and `lastname` columns.
-The annotated query uses native bind markers, which are Postgres bind markers in this example.
-====
-
-Note that the columns of a select statement used in a `@Query` annotation must match the names generated by the `NamingStrategy` for the respective property.
-If a select statement does not include a matching column, that property is not set. If that property is required by the persistence constructor, either null or (for primitive types) the default value is provided.
-
-The following table shows the keywords that are supported for query methods:
-
-[cols="1,2,3", options="header", subs="quotes"]
-.Supported keywords for query methods

-[[r2dbc.repositories.modifying]]
-=== Modifying Queries
-
-The previous sections describe how to declare queries to access a given entity or collection of entities.
-Using keywords from the preceding table can be used in conjunction with `delete…By` or `remove…By` to create derived queries that delete matching rows.
-
-.`Delete…By` Query
-====
-[source,java]
-----
-interface ReactivePersonRepository extends ReactiveSortingRepository<Person, String> {
-
-  Mono<Integer> deleteByLastname(String lastname);            <1>
-
-  Mono<Void> deletePersonByLastname(String lastname);         <2>
-
-  Mono<Boolean> deletePersonByLastname(String lastname);      <3>
-}
-----
-<1> Using a return type of `Mono<Integer>` returns the number of affected rows.
-<2> Using `Void` just reports whether the rows were successfully deleted without emitting a result value.
-<3> Using `Boolean` reports whether at least one row was removed.
-====
-
-As this approach is feasible for comprehensive custom functionality, you can modify queries that only need parameter binding by annotating the query method with `@Modifying`, as shown in the following example:
-
-====
-[source,java,indent=0]
-----
-include::../{example-root}/PersonRepository.java[tags=atModifying]
-----
-====
-
-The result of a modifying query can be:
-
-* `Void` (or Kotlin `Unit`) to discard update count and await completion.
-* `Integer` or another numeric type emitting the affected rows count.
-* `Boolean` to emit whether at least one row was updated.
-
-The `@Modifying` annotation is only relevant in combination with the `@Query` annotation.
-Derived custom methods do not require this annotation.
-
-Modifying queries are executed directly against the database.
-No events or callbacks get called.
-Therefore also fields with auditing annotations do not get updated if they don't get updated in the annotated query.
-
-Alternatively, you can add custom modifying behavior by using the facilities described in <<repositories.custom-implementations,Custom Implementations for Spring Data Repositories>>.
-
-[[r2dbc.repositories.queries.spel]]
-=== Queries with SpEL Expressions
-
-Query string definitions can be used together with SpEL expressions to create dynamic queries at runtime.
-SpEL expressions can provide predicate values which are evaluated right before running the query.
-
-Expressions expose method arguments through an array that contains all the arguments.
-The following query uses `[0]`
-to declare the predicate value for `lastname` (which is equivalent to the `:lastname` parameter binding):
-
-====
-[source,java,indent=0]
-----
-include::../{example-root}/PersonRepository.java[tags=spel]
-----
-====
-
-SpEL in query strings can be a powerful way to enhance queries.
-However, they can also accept a broad range of unwanted arguments.
-You should make sure to sanitize strings before passing them to the query to avoid unwanted changes to your query.
-
-Expression support is extensible through the Query SPI: `org.springframework.data.spel.spi.EvaluationContextExtension`.
-The Query SPI can contribute properties and functions and can customize the root object.
-Extensions are retrieved from the application context at the time of SpEL evaluation when the query is built.
-
-TIP: When using SpEL expressions in combination with plain parameters, use named parameter notation instead of native bind markers to ensure a proper binding order.
-
-[[r2dbc.repositories.queries.query-by-example]]
-=== Query By Example
-
-Spring Data R2DBC also lets you use Query By Example to fashion queries.
-This technique allows you to use a "probe" object.
-Essentially, any field that isn't empty or `null` will be used to match.
-
-Here's an example:
-
-====
-[source,java,indent=0]
-----
-include::../{example-root}/QueryByExampleTests.java[tag=example]
-----
-<1> Create a domain object with the criteria (`null` fields will be ignored).
-<2> Using the domain object, create an `Example`.
-<3> Through the `R2dbcRepository`, execute query (use `findOne` for a `Mono`).
-====
-
-This illustrates how to craft a simple probe using a domain object.
-In this case, it will query based on the `Employee` object's `name` field being equal to `Frodo`.
-`null` fields are ignored.
-
-====
-[source,java,indent=0]
-----
-include::../{example-root}/QueryByExampleTests.java[tag=example-2]
-----
-<1> Create a custom `ExampleMatcher` that matches on ALL fields (use `matchingAny()` to match on *ANY* fields)
-<2> For the `name` field, use a wildcard that matches against the end of the field
-<3> Match columns against `null` (don't forget that `NULL` doesn't equal `NULL` in relational databases).
-<4> Ignore the `role` field when forming the query.
-<5> Plug the custom `ExampleMatcher` into the probe.
-====
-
-It's also possible to apply a `withTransform()` against any property, allowing you to transform a property before forming the query.
-For example, you can apply a `toUpperCase()` to a `String` -based property before the query is created.
-
-Query By Example really shines when you you don't know all the fields needed in a query in advance.
-If you were building a filter on a web page where the user can pick the fields, Query By Example is a great way to flexibly capture that into an efficient query.
-
-[[r2dbc.entity-persistence.state-detection-strategies]]
-include::../{spring-data-commons-docs}/is-new-state-detection.adoc[leveloffset=+2]
-
-[[r2dbc.entity-persistence.id-generation]]
-=== ID Generation
-
-Spring Data R2DBC uses the ID to identify entities.
-The ID of an entity must be annotated with Spring Data's https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
-
-When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
-
-Spring Data R2DBC does not attempt to insert values of identifier columns when the entity is new and the identifier value defaults to its initial value.
-That is `0` for primitive types and `null` if the identifier property uses a numeric wrapper type such as `Long`.
-
-One important constraint is that, after saving an entity, the entity must not be new anymore.
-Note that whether an entity is new is part of the entity's state.
-With auto-increment columns, this happens automatically, because the ID gets set by Spring Data with the value from the ID column.
-
-[[r2dbc.optimistic-locking]]
-=== Optimistic Locking
-
-The `@Version` annotation provides syntax similar to that of JPA in the context of R2DBC and makes sure updates are only applied to rows with a matching version.
-Therefore, the actual value of the version property is added to the update query in such a way that the update does not have any effect if another operation altered the row in the meantime.
-In that case, an `OptimisticLockingFailureException` is thrown.
-The following example shows these features:
-
-====
-[source,java]
-----
-@Table
-class Person {
-
-  @Id Long id;
-  String firstname;
-  String lastname;
-  @Version Long version;
-}
-
-R2dbcEntityTemplate template = …;
-
-Mono<Person> daenerys = template.insert(new Person("Daenerys"));                      <1>
-
-Person other = template.select(Person.class)
-                 .matching(query(where("id").is(daenerys.getId())))
-                 .first().block();                                                    <2>
-
-daenerys.setLastname("Targaryen");
-template.update(daenerys);                                                            <3>
-
-template.update(other).subscribe(); // emits OptimisticLockingFailureException        <4>
-----
-<1> Initially insert row. `version` is set to `0`.
-<2> Load the just inserted row. `version` is still `0`.
-<3> Update the row with `version = 0`.Set the `lastname` and bump `version` to `1`.
-<4> Try to update the previously loaded row that still has `version = 0`.The operation fails with an `OptimisticLockingFailureException`, as the current `version` is `1`.
-====
-
-:projection-collection: Flux
-include::../{spring-data-commons-docs}/repository-projections.adoc[leveloffset=+2]
-
-[[projections.resultmapping]]
-==== Result Mapping
-
-A query method returning an Interface- or DTO projection is backed by results produced by the actual query.
-Interface projections generally rely on mapping results onto the domain type first to consider potential `@Column` type mappings and the actual projection proxy uses a potentially partially materialized entity to expose projection data.
-
-Result mapping for DTO projections depends on the actual query type.
-Derived queries use the domain type to map results, and Spring Data creates DTO instances solely from properties available on the domain type.
-Declaring properties in your DTO that are not available on the domain type is not supported.
-
-String-based queries use a different approach since the actual query, specifically the field projection, and result type declaration are close together.
-DTO projections used with query methods annotated with `@Query` map query results directly into the DTO type.
-Field mappings on the domain type are not considered.
-Using the DTO type directly, your query method can benefit from a more dynamic projection that isn't restricted to the domain model.
-
-include::../{spring-data-commons-docs}/entity-callbacks.adoc[leveloffset=+1]
-include::./r2dbc-entity-callbacks.adoc[leveloffset=+2]
-
-[[r2dbc.multiple-databases]]
-== Working with multiple Databases
-
-When working with multiple, potentially different databases, your application will require a different approach to configuration.
-The provided `AbstractR2dbcConfiguration` support class assumes a single `ConnectionFactory` from which the `Dialect` gets derived.
-That being said, you need to define a few beans yourself to configure Spring Data R2DBC to work with multiple databases.
-
-R2DBC repositories require `R2dbcEntityOperations` to implement repositories.
-A simple configuration to scan for repositories without using `AbstractR2dbcConfiguration` looks like:
-
-[source,java]
-----
-@Configuration
-@EnableR2dbcRepositories(basePackages = "com.acme.mysql", entityOperationsRef = "mysqlR2dbcEntityOperations")
-static class MySQLConfiguration {
-
-    @Bean
-    @Qualifier("mysql")
-    public ConnectionFactory mysqlConnectionFactory() {
-        return …
-    }
-
-    @Bean
-    public R2dbcEntityOperations mysqlR2dbcEntityOperations(@Qualifier("mysql") ConnectionFactory connectionFactory) {
-
-        DatabaseClient databaseClient = DatabaseClient.create(connectionFactory);
-
-        return new R2dbcEntityTemplate(databaseClient, MySqlDialect.INSTANCE);
-    }
-}
-----
-
-Note that `@EnableR2dbcRepositories` allows configuration either through `databaseClientRef` or `entityOperationsRef`.
-Using various `DatabaseClient` beans is useful when connecting to multiple databases of the same type.
-When using different database systems that differ in their dialect, use `@EnableR2dbcRepositories`(entityOperationsRef = …)` instead.

+The Spring Data JDBC module applies core Spring concepts to the development of solutions that use JDBC database drivers aligned with xref:jdbc/domain-driven-design.adoc[Domain-driven design principles].
+We provide a "`template`" as a high-level abstraction for storing and querying aggregates.
+
+This document is the reference guide for Spring Data JDBC support.
+It explains the concepts and semantics and syntax.
+
+This chapter points out the specialties for repository support for JDBC.
+This builds on the core repository support explained in xref:repositories/introduction.adoc[Working with Spring Data Repositories].
+You should have a sound understanding of the basic concepts explained there.

+<1> `@EnableJdbcRepositories` creates implementations for interfaces derived from `Repository`
+<2> `AbstractJdbcConfiguration` provides various default beans required by Spring Data JDBC
+<3> Creates a `DataSource` connecting to a database.
+This is required by the following two bean methods.
+<4> Creates the `NamedParameterJdbcOperations` used by Spring Data JDBC to access the database.
+<5> Spring Data JDBC utilizes the transaction management provided by Spring JDBC.
+
+The configuration class in the preceding example sets up an embedded HSQL database by using the `EmbeddedDatabaseBuilder` API of `spring-jdbc`.
+The `DataSource` is then used to set up `NamedParameterJdbcOperations` and a `TransactionManager`.
+We finally activate Spring Data JDBC repositories by using the `@EnableJdbcRepositories`.
+If no base package is configured, it uses the package in which the configuration class resides.
+Extending `AbstractJdbcConfiguration` ensures various beans get registered.
+Overwriting its methods can be used to customize the setup (see below).
+
+This configuration can be further simplified by using Spring Boot.
+With Spring Boot a `DataSource` is sufficient once the starter `spring-boot-starter-data-jdbc` is included in the dependencies.
+Everything else is done by Spring Boot.
+
+There are a couple of things one might want to customize in this setup.
+
+[[jdbc.dialects]]
+== Dialects
+
+Spring Data JDBC uses implementations of the interface `Dialect` to encapsulate behavior that is specific to a database or its JDBC driver.
+By default, the `AbstractJdbcConfiguration` tries to determine the database in use and register the correct `Dialect`.
+This behavior can be changed by overwriting `jdbcDialect(NamedParameterJdbcOperations)`.
+
+If you use a database for which no dialect is available, then your application won’t startup. In that case, you’ll have to ask your vendor to provide a `Dialect` implementation. Alternatively, you can:
+
+1. Implement your own `Dialect`.
+2. Implement a `JdbcDialectProvider` returning the `Dialect`.
+3. Register the provider by creating a `spring.factories`  resource under `META-INF` and perform the registration by adding a line +
+`org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider=<fully qualified name of your JdbcDialectProvider>`

+= Domain Driven Design and Relational Databases
+
+All Spring Data modules are inspired by the concepts of "`repository`", "`aggregate`", and "`aggregate root`" from Domain Driven Design.
+These are possibly even more important for Spring Data JDBC, because they are, to some extent, contrary to normal practice when working with relational databases.
+
+An aggregate is a group of entities that is guaranteed to be consistent between atomic changes to it.
+A classic example is an `Order` with `OrderItems`.
+A property on `Order` (for example, `numberOfItems` is consistent with the actual number of `OrderItems`) remains consistent as changes are made.
+
+References across aggregates are not guaranteed to be consistent at all times.
+They are guaranteed to become consistent eventually.
+
+Each aggregate has exactly one aggregate root, which is one of the entities of the aggregate.
+The aggregate gets manipulated only through methods on that aggregate root.
+These are the atomic changes mentioned earlier.
+
+A repository is an abstraction over a persistent store that looks like a collection of all the aggregates of a certain type.
+For Spring Data in general, this means you want to have one `Repository` per aggregate root.
+In addition, for Spring Data JDBC this means that all entities reachable from an aggregate root are considered to be part of that aggregate root.
+Spring Data JDBC assumes that only the aggregate has a foreign key to a table storing non-root entities of the aggregate and no other entity points toward non-root entities.
+
+WARNING: In the current implementation, entities referenced from an aggregate root are deleted and recreated by Spring Data JDBC.
+
+You can overwrite the repository methods with implementations that match your style of working and designing your database.

+= Persisting Entities
+
+Saving an aggregate can be performed with the `CrudRepository.save(…)` method.
+If the aggregate is new, this results in an insert for the aggregate root, followed by insert statements for all directly or indirectly referenced entities.
+
+If the aggregate root is not new, all referenced entities get deleted, the aggregate root gets updated, and all referenced entities get inserted again.
+Note that whether an instance is new is part of the instance's state.
+
+NOTE: This approach has some obvious downsides.
+If only few of the referenced entities have been actually changed, the deletion and insertion is wasteful.
+While this process could and probably will be improved, there are certain limitations to what Spring Data JDBC can offer.
+It does not know the previous state of an aggregate.
+So any update process always has to take whatever it finds in the database and make sure it converts it to whatever is the state of the entity passed to the save method.
+
+[[jdbc.entity-persistence.state-detection-strategies]]
+include::{commons}@data-commons::page$is-new-state-detection.adoc[leveloffset=+1]
+
+[[jdbc.entity-persistence.id-generation]]
+== ID Generation
+
+Spring Data JDBC uses the ID to identify entities.
+The ID of an entity must be annotated with Spring Data's https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
+
+When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
+
+One important constraint is that, after saving an entity, the entity must not be new any more.
+Note that whether an entity is new is part of the entity's state.
+With auto-increment columns, this happens automatically, because the ID gets set by Spring Data with the value from the ID column.
+If you are not using auto-increment columns, you can use a `BeforeConvertCallback` to set the ID of the entity (covered later in this document).
+
+[[jdbc.entity-persistence.optimistic-locking]]
+== Optimistic Locking
+
+Spring Data JDBC supports optimistic locking by means of a numeric attribute that is annotated with
+https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Version.html[`@Version`] on the aggregate root.
+Whenever Spring Data JDBC saves an aggregate with such a version attribute two things happen:
+The update statement for the aggregate root will contain a where clause checking that the version stored in the database is actually unchanged.
+If this isn't the case an `OptimisticLockingFailureException` will be thrown.
+Also the version attribute gets increased both in the entity and in the database so a concurrent action will notice the change and throw an `OptimisticLockingFailureException` if applicable as described above.
+
+This process also applies to inserting new aggregates, where a `null` or `0` version indicates a new instance and the increased instance afterwards marks the instance as not new anymore, making this work rather nicely with cases where the id is generated during object construction for example when UUIDs are used.

+[[jdbc.events]]
+= Lifecycle Events
+
+Spring Data JDBC publishes lifecycle events to `ApplicationListener` objects, typically beans in the application context.
+Events are notifications about a certain lifecycle phase.
+In contrast to entity callbacks, events are intended for notification.
+Transactional listeners will receive events when the transaction completes.
+Events and callbacks get only triggered for aggregate roots.
+If you want to process non-root entities, you need to do that through a listener for the containing aggregate root.
+
+Entity lifecycle events can be costly, and you may notice a change in the performance profile when loading large result sets.
+You can disable lifecycle events on the link:{spring-data-jdbc-javadoc}org/springframework/data/jdbc/core/JdbcAggregateTemplate.html#setEntityLifecycleEventsEnabled(boolean)[Template API].
+
+For example, the following listener gets invoked before an aggregate gets saved:
+
+[source,java]
+----
+@Bean
+ApplicationListener<BeforeSaveEvent<Object>> loggingSaves() {
+
+	return event -> {
+
+		Object entity = event.getEntity();
+		LOG.info("{} is getting saved.", entity);
+	};
+}
+----
+
+If you want to handle events only for a specific domain type you may derive your listener from `AbstractRelationalEventListener` and overwrite one or more of the `onXXX` methods, where `XXX` stands for an event type.
+Callback methods will only get invoked for events related to the domain type and their subtypes, therefore you don't require further casting.
+
+[source,java]
+----
+class PersonLoadListener extends AbstractRelationalEventListener<Person> {
+
+	@Override
+	protected void onAfterLoad(AfterLoadEvent<Person> personLoad) {
+		LOG.info(personLoad.getEntity());
+	}
+}
+----
+
+The following table describes the available events.For more details about the exact relation between process steps see the link:#jdbc.entity-callbacks[description of available callbacks] which map 1:1 to events.
+

+
+.Process Steps and Callbacks of the Different Processes performed by Spring Data JDBC.
+|===
+| Process | `EntityCallback` / Process Step | Comment
+
+.3+| Delete | {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/event/BeforeDeleteCallback.html[`BeforeDeleteCallback`]

+| After an aggregate gets deleted.
+
+
+.6+| Save 2+| Determine if an insert or an update of the aggregate is to be performed dependen on if it is new or not.
+| {spring-data-jdbc-javadoc}/org/springframework/data/relational/core/mapping/event/BeforeConvertCallback.html[`BeforeConvertCallback`]
+| This is the correct callback if you want to set an id programmatically. In the previous step new aggregates got detected as such and a Id generated in this step would be used in the following step.
+
+2+| Convert the aggregate to a aggregate change, it is a sequence of SQL statements to be executed against the database. In this step the decision is made if an Id is provided by the aggregate or if the Id is still empty and is expected to be generated by the database.
+
+| {spring-data-jdbc-javadoc}/org/springframework/data/relational/core/mapping/event/BeforeSaveCallback.html[`BeforeSaveCallback`]
+| Changes made to the aggregate root may get considered, but the decision if an id value will be sent to the database is already made in the previous step.
+Do not use this for creating Ids for new aggregates. Use `BeforeConvertCallback` instead.
+
+2+| The SQL statements determined above get executed against the database.
+
+| {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/event/AfterSaveCallback.html[`AfterSaveCallback`]

+| {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/event/AfterConvertCallback.html[`AfterConvertCallback`]
+|
+|===
+
+We encourage the use of callbacks over events since they support the use of immutable classes and therefore are more powerful and versatile than events.

+= Getting Started
+
+An easy way to bootstrap setting up a working environment is to create a Spring-based project in https://spring.io/tools[Spring Tools] or from https://start.spring.io[Spring Initializr].
+
+First, you need to set up a running database server. Refer to your vendor documentation on how to configure your database for JDBC access.
+
+[[requirements]]
+== Requirements
+
+Spring Data JDBC requires https://spring.io/docs[Spring Framework] {springVersion} and above.
+
+In terms of databases, Spring Data JDBC requires a xref:jdbc/configuration.adoc#jdbc.dialects[dialect] to abstract common SQL functionality over vendor-specific flavours.
+Spring Data JDBC includes direct support for the following databases:
+
+* DB2
+* H2
+* HSQLDB
+* MariaDB
+* Microsoft SQL Server
+* MySQL
+* Oracle
+* Postgres
+
+If you use a different database then your application won’t startup.
+The xref:jdbc/configuration.adoc#jdbc.dialects[dialect] section contains further detail on how to proceed in such case.
+
+To create a Spring project in STS:
+
+. Go to File -> New -> Spring Template Project -> Simple Spring Utility Project, and press Yes when prompted.
+Then enter a project and a package name, such as `org.spring.jdbc.example`.
+. Add the following to the `pom.xml` files `dependencies` element:
++
+[source,xml,subs="+attributes"]
+----
+<dependencies>
+
+  <!-- other dependency elements omitted -->
+
+  <dependency>
+    <groupId>org.springframework.data</groupId>
+    <artifactId>spring-data-jdbc</artifactId>
+    <version>{version}</version>
+  </dependency>
+

+----
+. Change the version of Spring in the pom.xml to be
++
+[source,xml,subs="+attributes"]
+----
+<spring.framework.version>{springVersion}</spring.framework.version>
+----
+. Add the following location of the Spring Milestone repository for Maven to your `pom.xml` such that it is at the same level of your `<dependencies/>` element:
++
+[source,xml]
+----
+<repositories>
+  <repository>
+    <id>spring-milestone</id>
+    <name>Spring Maven MILESTONE Repository</name>

+= Loading Aggregates
+
+Spring Data JDBC offers two ways how it can load aggregates.
+The traditional and before version 3.2 the only way is really simple:
+Each query loads the aggregate roots, independently if the query is based on a `CrudRepository` method, a derived query or a annotated query.
+If the aggregate root references other entities those are loaded with separate statements.
+
+Spring Data JDBC now allows the use of _Single Query Loading_.
+With this an arbitrary number of aggregates can be fully loaded with a single SQL query.
+This should be significant more efficient, especially for complex aggregates, consisting of many entities.
+
+Currently, this feature is very restricted.
+
+1. It only works for aggregates that only reference one entity collection.The plan is to remove this constraint in the future.
+
+2. The aggregate must also not use `AggregateReference` or embedded entities.The plan is to remove this constraint in the future.
+
+3. The database dialect must support it.Of the dialects provided by Spring Data JDBC all but H2 and HSQL support this.H2 and HSQL don't support analytic functions (aka windowing functions).
+
+4. It only works for the find methods in `CrudRepository`, not for derived queries and not for annotated queries.The plan is to remove this constraint in the future.
+
+5. Single Query Loading needs to be enabled in the `JdbcMappingContext`, by calling `setSingleQueryLoadingEnabled(true)`
+
+Note: Single Query Loading is to be considered experimental. We appreciate feedback on how it works for you.
+
+Note:Single Query Loading can be abbreviated as SQL, but we highly discourage that since confusion with Structured Query Language is almost guaranteed.

+= JDBC Locking
+
+Spring Data JDBC supports locking on derived query methods.
+To enable locking on a given derived query method inside a repository, you annotate it with `@Lock`.
+The required value of type `LockMode` offers two values: `PESSIMISTIC_READ` which guarantees that the data you are reading doesn't get modified and `PESSIMISTIC_WRITE` which obtains a lock to modify the data.
+Some databases do not make this distinction.
+In that cases both modes are equivalent of `PESSIMISTIC_WRITE`.
+
+.Using @Lock on derived query method
+[source,java]
+----
+interface UserRepository extends CrudRepository<User, Long> {
+
+  @Lock(LockMode.PESSIMISTIC_READ)
+  List<User> findByLastname(String lastname);
+}
+----
+
+As you can see above, the method `findByLastname(String lastname)` will be executed with a pessimistic read lock. If you are using a databse with the MySQL Dialect this will result for example in the following query:
+
+.Resulting Sql query for MySQL dialect
+[source,sql]
+----
+Select * from user u where u.lastname = lastname LOCK IN SHARE MODE
+----
+
+Alternative to `LockMode.PESSIMISTIC_READ` you can use `LockMode.PESSIMISTIC_WRITE`.

+[[mapping]]
+= Mapping
+
+Rich mapping support is provided by the `BasicJdbcConverter`. `BasicJdbcConverter` has a rich metadata model that allows mapping domain objects to a data row.
+The mapping metadata model is populated by using annotations on your domain objects.
+However, the infrastructure is not limited to using annotations as the only source of metadata information.
+The `BasicJdbcConverter` also lets you map objects to rows without providing any additional metadata, by following a set of conventions.
+
+This section describes the features of the `BasicJdbcConverter`, including how to use conventions for mapping objects to rows and how to override those conventions with annotation-based mapping metadata.
+
+Read on the basics about xref:object-mapping.adoc[] before continuing with this chapter.
+
+[[mapping.conventions]]
+== Convention-based Mapping
+
+`BasicJdbcConverter` has a few conventions for mapping objects to rows when no additional mapping metadata is provided.
+The conventions are:
+
+* The short Java class name is mapped to the table name in the following manner.
+The `com.bigbank.SavingsAccount` class maps to the `SAVINGS_ACCOUNT` table name.
+The same name mapping is applied for mapping fields to column names.
+For example, the `firstName` field maps to the `FIRST_NAME` column.
+You can control this mapping by providing a custom `NamingStrategy`.
+Table and column names that are derived from property or class names are used in SQL statements without quotes by default.
+You can control this behavior by setting `JdbcMappingContext.setForceQuote(true)`.
+
+* Nested objects are not supported.
+
+* The converter uses any Spring Converters registered with it to override the default mapping of object properties to row columns and values.
+
+* The fields of an object are used to convert to and from columns in the row.
+Public `JavaBean` properties are not used.
+
+* If you have a single non-zero-argument constructor whose constructor argument names match top-level column names of the row, that constructor is used.
+Otherwise, the zero-argument constructor is used.
+If there is more than one non-zero-argument constructor, an exception is thrown.
+
+[[jdbc.entity-persistence.types]]
+== Supported Types in Your Entity
+
+The properties of the following types are currently supported:
+
+* All primitive types and their boxed types (`int`, `float`, `Integer`, `Float`, and so on)
+
+* Enums get mapped to their name.
+
+* `String`
+
+* `java.util.Date`, `java.time.LocalDate`, `java.time.LocalDateTime`, and `java.time.LocalTime`
+
+* Arrays and Collections of the types mentioned above can be mapped to columns of array type if your database supports that.
+
+* Anything your database driver accepts.
+
+* References to other entities.
+They are considered a one-to-one relationship, or an embedded type.
+It is optional for one-to-one relationship entities to have an `id` attribute.
+The table of the referenced entity is expected to have an additional column with a name based on the referencing entity see xref:jdbc/entity-persistence.adoc#jdbc.entity-persistence.types.backrefs[Back References].
+Embedded entities do not need an `id`.
+If one is present it gets ignored.
+
+* `Set<some entity>` is considered a one-to-many relationship.
+The table of the referenced entity is expected to have an additional column with a name based on the referencing entity see xref:jdbc/entity-persistence.adoc#jdbc.entity-persistence.types.backrefs[Back References].
+
+* `Map<simple type, some entity>` is considered a qualified one-to-many relationship.
+The table of the referenced entity is expected to have two additional columns: One named based on the referencing entity for the foreign key (see xref:jdbc/entity-persistence.adoc#jdbc.entity-persistence.types.backrefs[Back References]) and one with the same name and an additional `_key` suffix for the map key.
+You can change this behavior by implementing `NamingStrategy.getReverseColumnName(PersistentPropertyPathExtension path)` and `NamingStrategy.getKeyColumn(RelationalPersistentProperty property)`, respectively.
+Alternatively you may annotate the attribute with `@MappedCollection(idColumn="your_column_name", keyColumn="your_key_column_name")`
+
+* `List<some entity>` is mapped as a  `Map<Integer, some entity>`.
+
+[[jdbc.entity-persistence.types.referenced-entities]]
+=== Referenced Entities
+
+The handling of referenced entities is limited.
+This is based on the idea of aggregate roots as described above.
+If you reference another entity, that entity is, by definition, part of your aggregate.
+So, if you remove the reference, the previously referenced entity gets deleted.
+This also means references are 1-1 or 1-n, but not n-1 or n-m.
+
+If you have n-1 or n-m references, you are, by definition, dealing with two separate aggregates.
+References between those may be encoded as simple `id` values, which map properly with Spring Data JDBC.
+A better way to encode these, is to make them instances of `AggregateReference`.
+An `AggregateReference` is a wrapper around an id value which marks that value as a reference to a different aggregate.
+Also, the type of that aggregate is encoded in a type parameter.
+
+[[jdbc.entity-persistence.types.backrefs]]
+=== Back References
+
+All references in an aggregate result in a foreign key relationship in the opposite direction in the database.
+By default, the name of the foreign key column is the table name of the referencing entity.
+
+Alternatively you may choose to have them named by the entity name of the referencing entity ignoreing `@Table` annotations.
+You activate this behaviour by calling `setForeignKeyNaming(ForeignKeyNaming.IGNORE_RENAMING)` on the `RelationalMappingContext`.
+
+For `List` and `Map` references an additional column is required for holding the list index or map key.
+It is based on the foreign key column with an additional `_KEY` suffix.
+
+If you want a completely different way of naming these back references you may implement `NamingStrategy.getReverseColumnName(PersistentPropertyPathExtension path)` in a way that fits your needs.
+
+.Declaring and setting an `AggregateReference`
+[source,java]
+----
+class Person {
+	@Id long id;
+	AggregateReference<Person, Long> bestFriend;
+}
+
+// ...
+
+Person p1, p2 = // some initialization
+
+p1.bestFriend = AggregateReference.to(p2.id);
+
+----
+
+* Types for which you registered suitable [[jdbc.custom-converters, custom conversions]].
+
+[[jdbc.entity-persistence.naming-strategy]]
+== `NamingStrategy`
+
+When you use the standard implementations of `CrudRepository` that Spring Data JDBC provides, they expect a certain table structure.
+You can tweak that by providing a {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/NamingStrategy.html[`NamingStrategy`] in your application context.
+
+[[jdbc.entity-persistence.custom-table-name]]
+== `Custom table names`
+
+When the NamingStrategy does not matching on your database table names, you can customize the names with the {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/Table.html[`@Table`] annotation.
+The element `value` of this annotation provides the custom table name.
+The following example maps the `MyEntity` class to the `CUSTOM_TABLE_NAME` table in the database:
+
+[source,java]
+----
+@Table("CUSTOM_TABLE_NAME")
+class MyEntity {
+    @Id
+    Integer id;
+
+    String name;
+}
+----
+
+[[jdbc.entity-persistence.custom-column-name]]
+== `Custom column names`
+
+When the NamingStrategy does not matching on your database column names, you can customize the names with the {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/Column.html[`@Column`] annotation.
+The element `value` of this annotation provides the custom column name.
+The following example maps the `name` property of the `MyEntity` class to the `CUSTOM_COLUMN_NAME` column in the database:
+
+[source,java]
+----
+class MyEntity {
+    @Id
+    Integer id;
+
+    @Column("CUSTOM_COLUMN_NAME")
+    String name;
+}
+----
+
+The {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/MappedCollection.html[`@MappedCollection`]
+annotation can be used on a reference type (one-to-one relationship) or on Sets, Lists, and Maps (one-to-many relationship).
+`idColumn` element of the annotation provides a custom name for the foreign key column referencing the id column in the other table.
+In the following example the corresponding table for the `MySubEntity` class has a `NAME` column, and the `CUSTOM_MY_ENTITY_ID_COLUMN_NAME` column of the `MyEntity` id for relationship reasons:
+
+[source,java]
+----
+class MyEntity {
+    @Id
+    Integer id;
+
+    @MappedCollection(idColumn = "CUSTOM_MY_ENTITY_ID_COLUMN_NAME")
+    Set<MySubEntity> subEntities;
+}
+
+class MySubEntity {
+    String name;
+}
+----
+
+When using `List` and `Map` you must have an additional column for the position of a dataset in the `List` or the key value of the entity in the `Map`.
+This additional column name may be customized with the `keyColumn` Element of the {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/MappedCollection.html[`@MappedCollection`] annotation:
+
+[source,java]
+----
+class MyEntity {
+    @Id
+    Integer id;
+
+    @MappedCollection(idColumn = "CUSTOM_COLUMN_NAME", keyColumn = "CUSTOM_KEY_COLUMN_NAME")
+    List<MySubEntity> name;
+}
+
+class MySubEntity {
+    String name;
+}
+----
+
+[[jdbc.entity-persistence.embedded-entities]]
+== Embedded entities
+
+Embedded entities are used to have value objects in your java data model, even if there is only one table in your database.
+In the following example you see, that `MyEntity` is mapped with the `@Embedded` annotation.
+The consequence of this is, that in the database a table `my_entity` with the two columns `id` and `name` (from the `EmbeddedEntity` class) is expected.
+
+However, if the `name` column is actually `null` within the result set, the entire property `embeddedEntity` will be set to null according to the `onEmpty` of `@Embedded`, which ``null``s objects when all nested properties are `null`. +
+Opposite to this behavior `USE_EMPTY` tries to create a new instance using either a default constructor or one that accepts nullable parameter values from the result set.
+
+.Sample Code of embedding objects
+====
+[source,java]
+----
+class MyEntity {
+
+    @Id
+    Integer id;
+
+    @Embedded(onEmpty = USE_NULL) <1>
+    EmbeddedEntity embeddedEntity;
+}
+
+class EmbeddedEntity {
+    String name;
+}
+----
+
+<1> ``Null``s `embeddedEntity` if `name` in `null`.
+Use `USE_EMPTY` to instantiate `embeddedEntity` with a potential `null` value for the `name` property.
+====
+
+If you need a value object multiple times in an entity, this can be achieved with the optional `prefix` element of the `@Embedded` annotation.
+This element represents a prefix and is prepend for each column name in the embedded object.
+
+[TIP]
+====
+Make use of the shortcuts `@Embedded.Nullable` & `@Embedded.Empty` for `@Embedded(onEmpty = USE_NULL)` and `@Embedded(onEmpty = USE_EMPTY)` to reduce verbosity and simultaneously set JSR-305 `@javax.annotation.Nonnull` accordingly.
+
+[source,java]
+----
+class MyEntity {
+
+    @Id
+    Integer id;
+
+    @Embedded.Nullable <1>
+    EmbeddedEntity embeddedEntity;
+}
+----
+
+<1> Shortcut for `@Embedded(onEmpty = USE_NULL)`.
+====
+
+Embedded entities containing a `Collection` or a `Map` will always be considered non empty since they will at least contain the empty collection or map.
+Such an entity will therefore never be `null` even when using @Embedded(onEmpty = USE_NULL).
+
+[[jdbc.entity-persistence.read-only-properties]]
+== Read Only Properties
+
+Attributes annotated with `@ReadOnlyProperty` will not be written to the database by Spring Data JDBC, but they will be read when an entity gets loaded.
+
+Spring Data JDBC will not automatically reload an entity after writing it.
+Therefore, you have to reload it explicitly if you want to see data that was generated in the database for such columns.
+
+If the annotated attribute is an entity or collection of entities, it is represented by one or more separate rows in separate tables.
+Spring Data JDBC will not perform any insert, delete or update for these rows.
+
+[[jdbc.entity-persistence.insert-only-properties]]
+== Insert Only Properties
+
+Attributes annotated with `@InsertOnlyProperty` will only be written to the database by Spring Data JDBC during insert operations.
+For updates these properties will be ignored.
+
+`@InsertOnlyProperty` is only supported for the aggregate root.

+The easiest way to properly plug MyBatis into Spring Data JDBC is by importing `MyBatisJdbcConfiguration` into you application configuration:
+
+[source,java]
+----
+@Configuration
+@EnableJdbcRepositories
+@Import(MyBatisJdbcConfiguration.class)
+class Application {
+
+  @Bean
+  SqlSessionFactoryBean sqlSessionFactoryBean() {
+    // Configure MyBatis here
+  }
+}
+----
+
+As you can see, all you need to declare is a `SqlSessionFactoryBean` as `MyBatisJdbcConfiguration` relies on a `SqlSession` bean to be available in the `ApplicationContext` eventually.
+
+[[jdbc.mybatis.conventions]]
+== Usage conventions
+
+For each operation in `CrudRepository`, Spring Data JDBC runs multiple statements.
+If there is a https://github.com/mybatis/mybatis-3/blob/master/src/main/java/org/apache/ibatis/session/SqlSessionFactory.java[`SqlSessionFactory`] in the application context, Spring Data checks, for each step, whether the `SessionFactory` offers a statement.
+If one is found, that statement (including its configured mapping to an entity) is used.
+
+The name of the statement is constructed by concatenating the fully qualified name of the entity type with `Mapper.` and a `String` determining the kind of statement.
+For example, if an instance of `org.example.User` is to be inserted, Spring Data JDBC looks for a statement named `org.example.UserMapper.insert`.
+
+When the statement is run, an instance of [`MyBatisContext`] gets passed as an argument, which makes various arguments available to the statement.
+
+The following table describes the available MyBatis statements:
+
+[cols="default,default,default,asciidoc"]
+|===
+| Name | Purpose | CrudRepository methods that might trigger this statement | Attributes available in the `MyBatisContext`
+
+| `insert` | Inserts a single entity. This also applies for entities referenced by the aggregate root. | `save`, `saveAll`. |
+`getInstance`: the instance to be saved
+
+`getDomainType`: The type of the entity to be saved.
+
+`get(<key>)`: ID of the referencing entity, where `<key>` is the name of the back reference column provided by the `NamingStrategy`.
+
+
+| `update` | Updates a single entity. This also applies for entities referenced by the aggregate root. | `save`, `saveAll`.|
+`getInstance`: The instance to be saved

+
+| `deleteAll-<propertyPath>` | Deletes all entities referenced by any aggregate root of the type used as prefix with the given property path.
+Note that the type used for prefixing the statement name is the name of the aggregate root, not the one of the entity to be deleted. | `deleteAll`.|
+
+`getDomainType`: The types of the entities to be deleted.
+
+| `deleteAll` | Deletes all aggregate roots of the type used as the prefix | `deleteAll`.|
+

+
+| `delete-<propertyPath>` | Deletes all entities referenced by an aggregate root with the given propertyPath | `deleteById`.|
+
+`getId`: The ID of the aggregate root for which referenced entities are to be deleted.
+
+`getDomainType`: The type of the entities to be deleted.
+
+| `findById` | Selects an aggregate root by ID | `findById`.|
+
+`getId`: The ID of the entity to load.
+
+`getDomainType`: The type of the entity to load.
+
+| `findAll` | Select all aggregate roots | `findAll`.|

+= Query Methods
+
+This section offers some specific information about the implementation and use of Spring Data JDBC.
+
+Most of the data access operations you usually trigger on a repository result in a query being run against the databases.
+Defining such a query is a matter of declaring a method on the repository interface, as the following example shows:
+
+.PersonRepository with query methods
+[source,java]
+----
+interface PersonRepository extends PagingAndSortingRepository<Person, String> {
+
+  List<Person> findByFirstname(String firstname);                                   <1>
+
+  List<Person> findByFirstnameOrderByLastname(String firstname, Pageable pageable); <2>
+
+  Slice<Person> findByLastname(String lastname, Pageable pageable);                 <3>
+
+  Page<Person> findByLastname(String lastname, Pageable pageable);                  <4>
+
+  Person findByFirstnameAndLastname(String firstname, String lastname);             <5>
+
+  Person findFirstByLastname(String lastname);                                      <6>
+
+  @Query("SELECT * FROM person WHERE lastname = :lastname")
+  List<Person> findByLastname(String lastname);                                     <7>
+  @Query("SELECT * FROM person WHERE lastname = :lastname")
+  Stream<Person> streamByLastname(String lastname);                                     <8>
+
+  @Query("SELECT * FROM person WHERE username = :#{ principal?.username }")
+  Person findActiveUser();															<9>
+}
+----
+<1> The method shows a query for all people with the given `firstname`.
+The query is derived by parsing the method name for constraints that can be concatenated with `And` and `Or`.
+Thus, the method name results in a query expression of `SELECT … FROM person WHERE firstname = :firstname`.
+<2> Use `Pageable` to pass offset and sorting parameters to the database.
+<3> Return a `Slice<Person>`.Selects `LIMIT+1` rows to determine whether there's more data to consume. `ResultSetExtractor` customization is not supported.
+<4> Run a paginated query returning `Page<Person>`.Selects only data within the given page bounds and potentially a count query to determine the total count. `ResultSetExtractor` customization is not supported.
+<5> Find a single entity for the given criteria.
+It completes with `IncorrectResultSizeDataAccessException` on non-unique results.
+<6> In contrast to <3>, the first entity is always emitted even if the query yields more result documents.
+<7> The `findByLastname` method shows a query for all people with the given `lastname`.
+<8> The `streamByLastname` method returns a `Stream`, which makes values possible as soon as they are returned from the database.
+<9> You can use the Spring Expression Language to dynamically resolve parameters.
+In the sample, Spring Security is used to resolve the username of the current user.
+
+The following table shows the keywords that are supported for query methods:
+
+[cols="1,2,3",options="header",subs="quotes"]
+.Supported keywords for query methods
+|===
+| Keyword
+| Sample
+| Logical result
+
+| `After`
+| `findByBirthdateAfter(Date date)`
+| `birthdate > date`
+
+| `GreaterThan`
+| `findByAgeGreaterThan(int age)`
+| `age > age`
+
+| `GreaterThanEqual`
+| `findByAgeGreaterThanEqual(int age)`
+| `age >= age`
+
+| `Before`
+| `findByBirthdateBefore(Date date)`
+| `birthdate < date`
+
+| `LessThan`
+| `findByAgeLessThan(int age)`
+| `age < age`
+
+| `LessThanEqual`
+| `findByAgeLessThanEqual(int age)`

+| `findByAgeNotBetween(int from, int to)`
+| `age NOT BETWEEN from AND to`
+
+| `In`
+| `findByAgeIn(Collection<Integer> ages)`
+| `age IN (age1, age2, ageN)`
+
+| `NotIn`
+| `findByAgeNotIn(Collection ages)`
+| `age NOT IN (age1, age2, ageN)`
+
+| `IsNotNull`, `NotNull`
+| `findByFirstnameNotNull()`
+| `firstname IS NOT NULL`
+
+| `IsNull`, `Null`
+| `findByFirstnameNull()`
+| `firstname IS NULL`
+
+| `Like`, `StartingWith`, `EndingWith`
+| `findByFirstnameLike(String name)`
+| `firstname LIKE name`
+
+| `NotLike`, `IsNotLike`
+| `findByFirstnameNotLike(String name)`
+| `firstname NOT LIKE name`
+
+| `Containing` on String
+| `findByFirstnameContaining(String name)`
+| `firstname LIKE '%' + name + '%'`
+
+| `NotContaining` on String
+| `findByFirstnameNotContaining(String name)`
+| `firstname NOT LIKE '%' + name + '%'`
+
+| `(No keyword)`
+| `findByFirstname(String name)`
+| `firstname = name`
+
+| `Not`
+| `findByFirstnameNot(String name)`
+| `firstname != name`
+
+| `IsTrue`, `True`
+| `findByActiveIsTrue()`
+| `active IS TRUE`
+
+| `IsFalse`,  `False`
+| `findByActiveIsFalse()`
+| `active IS FALSE`
+|===
+
+NOTE: Query derivation is limited to properties that can be used in a `WHERE` clause without using joins.
+
+[[jdbc.query-methods.strategies]]
+== Query Lookup Strategies
+
+The JDBC module supports defining a query manually as a String in a `@Query` annotation or as named query in a property file.
+
+Deriving a query from the name of the method is is currently limited to simple properties, that means properties present in the aggregate root directly.
+Also, only select queries are supported by this approach.
+
+[[jdbc.query-methods.at-query]]
+== Using `@Query`
+
+The following example shows how to use `@Query` to declare a query method:
+
+.Declare a query method by using @Query
+[source,java]
+----
+interface UserRepository extends CrudRepository<User, Long> {
+
+  @Query("select firstName, lastName from User u where u.emailAddress = :email")
+  User findByEmailAddress(@Param("email") String email);
+}
+----
+
+For converting the query result into entities the same `RowMapper` is used by default as for the queries Spring Data JDBC generates itself.
+The query you provide must match the format the `RowMapper` expects.
+Columns for all properties that are used in the constructor of an entity must be provided.
+Columns for properties that get set via setter, wither or field access are optional.
+Properties that don't have a matching column in the result will not be set.
+The query is used for populating the aggregate root, embedded entities and one-to-one relationships including arrays of primitive types which get stored and loaded as SQL-array-types.
+Separate queries are generated for maps, lists, sets and arrays of entities.
+
+NOTE: Spring fully supports Java 8’s parameter name discovery based on the `-parameters` compiler flag.
+By using this flag in your build as an alternative to debug information, you can omit the `@Param` annotation for named parameters.
+
+NOTE: Spring Data JDBC supports only named parameters.
+
+[[jdbc.query-methods.named-query]]
+== Named Queries
+
+If no query is given in an annotation as described in the previous section Spring Data JDBC will try to locate a named query.
+There are two ways how the name of the query can be determined.
+The default is to take the _domain class_ of the query, i.e. the aggregate root of the repository, take its simple name and append the name of the method separated by a `.`.
+Alternatively the `@Query` annotation has a `name` attribute which can be used to specify the name of a query to be looked up.
+
+Named queries are expected to be provided in the property file `META-INF/jdbc-named-queries.properties` on the classpath.
+
+The location of that file may be changed by setting a value to `@EnableJdbcRepositories.namedQueriesLocation`.
+
+[[jdbc.query-methods.at-query.streaming-results]]
+=== Streaming Results
+
+When you specify Stream as the return type of a query method, Spring Data JDBC returns elements as soon as they become available.
+When dealing with large amounts of data this is suitable for reducing latency and memory requirements.
+
+The stream contains an open connection to the database.
+To avoid memory leaks, that connection needs to be closed eventually, by closing the stream.
+The recommended way to do that is a `try-with-resource clause`.
+It also means that, once the connection to the database is closed, the stream cannot obtain further elements and likely throws an exception.
+
+[[jdbc.query-methods.at-query.custom-rowmapper]]
+=== Custom `RowMapper`
+
+You can configure which `RowMapper` to use, either by using the `@Query(rowMapperClass = ....)` or by registering a `RowMapperMap` bean and registering a `RowMapper` per method return type.
+The following example shows how to register `DefaultQueryMappingConfiguration`:
+
+[source,java]
+----
+@Bean
+QueryMappingConfiguration rowMappers() {
+  return new DefaultQueryMappingConfiguration()
+    .register(Person.class, new PersonRowMapper())
+    .register(Address.class, new AddressRowMapper());
+}
+----
+
+When determining which `RowMapper` to use for a method, the following steps are followed, based on the return type of the method:
+
+. If the type is a simple type, no `RowMapper` is used.
++
+Instead, the query is expected to return a single row with a single column, and a conversion to the return type is applied to that value.
+. The entity classes in the `QueryMappingConfiguration` are iterated until one is found that is a superclass or interface of the return type in question.
+The `RowMapper` registered for that class is used.
++
+Iterating happens in the order of registration, so make sure to register more general types after specific ones.
+
+If applicable, wrapper types such as collections or `Optional` are unwrapped.
+Thus, a return type of `Optional<Person>` uses the `Person` type in the preceding process.
+
+NOTE: Using a custom `RowMapper` through `QueryMappingConfiguration`, `@Query(rowMapperClass=…)`, or a custom `ResultSetExtractor` disables Entity Callbacks and Lifecycle Events as the result mapping can issue its own events/callbacks if needed.
+
+[[jdbc.query-methods.at-query.modifying]]
+=== Modifying Query
+
+You can mark a query as being a modifying query by using the `@Modifying` on query method, as the following example shows:
+
+[source,java]
+----
+@Modifying
+@Query("UPDATE DUMMYENTITY SET name = :name WHERE id = :id")
+boolean updateName(@Param("id") Long id, @Param("name") String name);
+----
+
+You can specify the following return types:
+
+* `void`
+* `int` (updated record count)
+* `boolean`(whether a record was updated)
+
+Modifying queries are executed directly against the database.
+No events or callbacks get called.
+Therefore also fields with auditing annotations do not get updated if they don't get updated in the annotated query.

+[[jdbc.transactions]]
+= Transactionality
+
+The methods of `CrudRepository` instances are transactional by default.
+For reading operations, the transaction configuration `readOnly` flag is set to `true`.
+All others are configured with a plain `@Transactional` annotation so that default transaction configuration applies.
+For details, see the Javadoc of link:{spring-data-jdbc-javadoc}org/springframework/data/jdbc/repository/support/SimpleJdbcRepository.html[`SimpleJdbcRepository`].
+If you need to tweak transaction configuration for one of the methods declared in a repository, redeclare the method in your repository interface, as follows:
+
+.Custom transaction configuration for CRUD
+[source,java]
+----
+interface UserRepository extends CrudRepository<User, Long> {
+
+  @Override
+  @Transactional(timeout = 10)
+  List<User> findAll();
+
+  // Further query method declarations
+}
+----
+
+The preceding causes the `findAll()` method to be run with a timeout of 10 seconds and without the `readOnly` flag.
+
+Another way to alter transactional behavior is by using a facade or service implementation that typically covers more than one repository.
+Its purpose is to define transactional boundaries for non-CRUD operations.
+The following example shows how to create such a facade:
+
+.Using a facade to define transactions for multiple repository calls
+[source,java]
+----
+@Service
+public class UserManagementImpl implements UserManagement {
+
+  private final UserRepository userRepository;
+  private final RoleRepository roleRepository;
+
+  UserManagementImpl(UserRepository userRepository,
+    RoleRepository roleRepository) {
+    this.userRepository = userRepository;
+    this.roleRepository = roleRepository;
+  }
+
+  @Transactional
+  public void addRoleToAllUsers(String roleName) {
+
+    Role role = roleRepository.findByName(roleName);
+
+    for (User user : userRepository.findAll()) {
+      user.addRole(role);
+      userRepository.save(user);
+    }
+}
+----
+
+The preceding example causes calls to `addRoleToAllUsers(…)` to run inside a transaction (participating in an existing one or creating a new one if none are already running).
+The transaction configuration for the repositories is neglected, as the outer transaction configuration determines the actual repository to be used.
+Note that you have to explicitly activate `<tx:annotation-driven />` or use `@EnableTransactionManagement` to get annotation-based configuration for facades working.
+Note that the preceding example assumes you use component scanning.
+
+[[jdbc.transaction.query-methods]]
+== Transactional Query Methods
+
+To let your query methods be transactional, use `@Transactional` at the repository interface you define, as the following example shows:
+
+.Using @Transactional at query methods
+[source,java]
+----
+@Transactional(readOnly = true)
+interface UserRepository extends CrudRepository<User, Long> {
+
+  List<User> findByLastname(String lastname);
+
+  @Modifying
+  @Transactional
+  @Query("delete from User u where u.active = false")
+  void deleteInactiveUsers();
+}
+----
+
+Typically, you want the `readOnly` flag to be set to true, because most of the query methods only read data.
+In contrast to that, `deleteInactiveUsers()` uses the `@Modifying` annotation and overrides the transaction configuration.
+Thus, the method is with the `readOnly` flag set to `false`.
+
+NOTE: It is highly recommended to make query methods transactional. These methods might execute more then one query in order to populate an entity.
+Without a common transaction Spring Data JDBC executes the queries in different connections.
+This may put excessive strain on the connection pool and might even lead to dead locks when multiple methods request a fresh connection while holding on to one.
+
+NOTE: It is definitely reasonable to mark read-only queries as such by setting the `readOnly` flag.
+This does not, however, act as a check that you do not trigger a manipulating query (although some databases reject `INSERT` and `UPDATE` statements inside a read-only transaction).
+Instead, the `readOnly` flag is propagated as a hint to the underlying JDBC driver for performance optimizations.
+

+= Why Spring Data JDBC?
+
+The main persistence API for relational databases in the Java world is certainly JPA, which has its own Spring Data module.
+Why is there another one?
+
+JPA does a lot of things in order to help the developer.
+Among other things, it tracks changes to entities.
+It does lazy loading for you.
+It lets you map a wide array of object constructs to an equally wide array of database designs.
+
+This is great and makes a lot of things really easy.
+Just take a look at a basic JPA tutorial.
+But it often gets really confusing as to why JPA does a certain thing.
+Also, things that are really simple conceptually get rather difficult with JPA.
+
+Spring Data JDBC aims to be much simpler conceptually, by embracing the following design decisions:
+
+* If you load an entity, SQL statements get run.
+Once this is done, you have a completely loaded entity.
+No lazy loading or caching is done.
+
+* If you save an entity, it gets saved.
+If you do not, it does not.
+There is no dirty tracking and no session.
+
+* There is a simple model of how to map entities to tables.
+It probably only works for rather simple cases.
+If you do not like that, you should code your own strategy.
+Spring Data JDBC offers only very limited support for customizing the strategy with annotations.

+The Spring Data R2DBC module applies core Spring concepts to the development of solutions that use R2DBC database drivers aligned with xref:jdbc/domain-driven-design.adoc[Domain-driven design principles].
+We provide a "`template`" as a high-level abstraction for storing and querying aggregates.
+
+This document is the reference guide for Spring Data R2DBC support.
+It explains the concepts and semantics and syntax.
+
+This chapter points out the specialties for repository support for JDBC.
+This builds on the core repository support explained in xref:repositories/introduction.adoc[Working with Spring Data Repositories].
+You should have a sound understanding of the basic concepts explained there.

 If you expose a bean of type `ReactiveAuditorAware` to the `ApplicationContext`, the auditing infrastructure picks it up automatically and uses it to determine the current user to be set on domain types.
 If you have multiple implementations registered in the `ApplicationContext`, you can select the one to be used by explicitly setting the `auditorAwareRef` attribute of `@EnableR2dbcAuditing`.

+= Query By Example
+
+Spring Data R2DBC also lets you use xref:query-by-example.adoc[Query By Example] to fashion queries.
+This technique allows you to use a "probe" object.
+Essentially, any field that isn't empty or `null` will be used to match.
+
+Here's an example:
+
+[source,java,indent=0]
+----
+include::example$r2dbc/QueryByExampleTests.java[tag=example]
+----
+
+<1> Create a domain object with the criteria (`null` fields will be ignored).
+<2> Using the domain object, create an `Example`.
+<3> Through the `R2dbcRepository`, execute query (use `findOne` for a `Mono`).
+
+This illustrates how to craft a simple probe using a domain object.
+In this case, it will query based on the `Employee` object's `name` field being equal to `Frodo`.
+`null` fields are ignored.
+
+[source,java,indent=0]
+----
+include::example$r2dbc/QueryByExampleTests.java[tag=example-2]
+----
+
+<1> Create a custom `ExampleMatcher` that matches on ALL fields (use `matchingAny()` to match on *ANY* fields)
+<2> For the `name` field, use a wildcard that matches against the end of the field
+<3> Match columns against `null` (don't forget that `NULL` doesn't equal `NULL` in relational databases).
+<4> Ignore the `role` field when forming the query.
+<5> Plug the custom `ExampleMatcher` into the probe.
+
+It's also possible to apply a `withTransform()` against any property, allowing you to transform a property before forming the query.
+For example, you can apply a `toUpperCase()` to a `String` -based property before the query is created.
+
+Query By Example really shines when you don't know all the fields needed in a query in advance.
+If you were building a filter on a web page where the user can pick the fields, Query By Example is a great way to flexibly capture that into an efficient query.

+The query is derived by parsing the method name for constraints that can be concatenated with `And` and `Or`.

+<3> Use `Pageable` to pass offset and sorting parameters to the database.

+<5> Unless <4>, the first entity is always emitted even if the query yields more result rows.
+<6> The `findByLastname` method shows a query for all people with the given last name.
+<7> A query for a single `Person` entity projecting only `firstname` and `lastname` columns.
+The annotated query uses native bind markers, which are Postgres bind markers in this example.
+====
+
+Note that the columns of a select statement used in a `@Query` annotation must match the names generated by the `NamingStrategy` for the respective property.
+If a select statement does not include a matching column, that property is not set.
+If that property is required by the persistence constructor, either null or (for primitive types) the default value is provided.

+[[r2dbc.repositories.modifying]]
+== Modifying Queries
+
+The previous sections describe how to declare queries to access a given entity or collection of entities.
+Using keywords from the preceding table can be used in conjunction with `delete…By` or `remove…By` to create derived queries that delete matching rows.
+
+.`Delete…By` Query
+====
+[source,java]
+----
+interface ReactivePersonRepository extends ReactiveSortingRepository<Person, String> {
+
+  Mono<Integer> deleteByLastname(String lastname);            <1>
+
+  Mono<Void> deletePersonByLastname(String lastname);         <2>
+
+  Mono<Boolean> deletePersonByLastname(String lastname);      <3>
+}
+----
+
+<1> Using a return type of `Mono<Integer>` returns the number of affected rows.
+<2> Using `Void` just reports whether the rows were successfully deleted without emitting a result value.
+<3> Using `Boolean` reports whether at least one row was removed.
+====
+
+As this approach is feasible for comprehensive custom functionality, you can modify queries that only need parameter binding by annotating the query method with `@Modifying`, as shown in the following example:
+
+[source,java,indent=0]
+----
+include::example$r2dbc/PersonRepository.java[tags=atModifying]
+----
+
+The result of a modifying query can be:
+
+* `Void` (or Kotlin `Unit`) to discard update count and await completion.
+* `Integer` or another numeric type emitting the affected rows count.
+* `Boolean` to emit whether at least one row was updated.
+
+The `@Modifying` annotation is only relevant in combination with the `@Query` annotation.
+Derived custom methods do not require this annotation.
+
+Modifying queries are executed directly against the database.
+No events or callbacks get called.
+Therefore also fields with auditing annotations do not get updated if they don't get updated in the annotated query.
+
+Alternatively, you can add custom modifying behavior by using the facilities described in xref:repositories/custom-implementations.adoc[Custom Implementations for Spring Data Repositories].
+
+[[r2dbc.repositories.queries.spel]]
+=== Queries with SpEL Expressions
+
+Query string definitions can be used together with SpEL expressions to create dynamic queries at runtime.
+SpEL expressions can provide predicate values which are evaluated right before running the query.
+
+Expressions expose method arguments through an array that contains all the arguments.
+The following query uses `[0]`
+to declare the predicate value for `lastname` (which is equivalent to the `:lastname` parameter binding):
+
+[source,java,indent=0]
+----
+include::example$r2dbc/PersonRepository.java[tags=spel]
+----
+
+SpEL in query strings can be a powerful way to enhance queries.
+However, they can also accept a broad range of unwanted arguments.
+You should make sure to sanitize strings before passing them to the query to avoid unwanted changes to your query.
+
+Expression support is extensible through the Query SPI: `org.springframework.data.spel.spi.EvaluationContextExtension`.
+The Query SPI can contribute properties and functions and can customize the root object.
+Extensions are retrieved from the application context at the time of SpEL evaluation when the query is built.
+
+TIP: When using SpEL expressions in combination with plain parameters, use named parameter notation instead of native bind markers to ensure a proper binding order.

+= R2DBC Repositories
+
+[[r2dbc.repositories.intro]]
+This chapter points out the specialties for repository support for R2DBC.
+This builds on the core repository support explained in xref:repositories/introduction.adoc[Working with Spring Data Repositories].
+Before reading this chapter, you should have a sound understanding of the basic concepts explained there.
+
+[[r2dbc.repositories.usage]]
+== Usage
+
+To access domain entities stored in a relational database, you can use our sophisticated repository support that eases implementation quite significantly.
+To do so, create an interface for your repository.
+Consider the following `Person` class:
+
+.Sample Person entity
+[source,java]
+----
+public class Person {
+
+  @Id
+  private Long id;
+  private String firstname;
+  private String lastname;
+
+  // … getters and setters omitted
+}
+----
+
+The following example shows a repository interface for the preceding `Person` class:
+
+.Basic repository interface to persist Person entities
+[source,java]
+----
+public interface PersonRepository extends ReactiveCrudRepository<Person, Long> {
+
+  // additional custom query methods go here
+}
+----
+
+To configure R2DBC repositories, you can use the `@EnableR2dbcRepositories` annotation.
+If no base package is configured, the infrastructure scans the package of the annotated configuration class.
+The following example shows how to use Java configuration for a repository:
+
+.Java configuration for repositories
+[source,java]
+----
+@Configuration
+@EnableR2dbcRepositories
+class ApplicationConfig extends AbstractR2dbcConfiguration {
+
+  @Override
+  public ConnectionFactory connectionFactory() {
+    return …
+  }
+}
+----
+
+Because our domain repository extends `ReactiveCrudRepository`, it provides you with reactive CRUD operations to access the entities.
+On top of `ReactiveCrudRepository`, there is also `ReactiveSortingRepository`, which adds additional sorting functionality similar to that of `PagingAndSortingRepository`.
+Working with the repository instance is merely a matter of dependency injecting it into a client.
+Consequently, you can retrieve all `Person` objects with the following code:
+
+.Paging access to Person entities
+[source,java,indent=0]
+----
+include::example$r2dbc/PersonRepositoryTests.java[tags=class]
+----
+
+The preceding example creates an application context with Spring's unit test support, which performs annotation-based dependency injection into test cases.
+Inside the test method, we use the repository to query the database.
+We use `StepVerifier` as a test aid to verify our expectations against the results.
+
+[[r2dbc.entity-persistence.state-detection-strategies]]
+include::{commons}@data-commons::page$is-new-state-detection.adoc[leveloffset=+1]
+
+[[r2dbc.entity-persistence.id-generation]]
+=== ID Generation
+
+Spring Data R2DBC uses the ID to identify entities.
+The ID of an entity must be annotated with Spring Data's https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
+
+When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
+
+Spring Data R2DBC does not attempt to insert values of identifier columns when the entity is new and the identifier value defaults to its initial value.
+That is `0` for primitive types and `null` if the identifier property uses a numeric wrapper type such as `Long`.
+
+One important constraint is that, after saving an entity, the entity must not be new anymore.
+Note that whether an entity is new is part of the entity's state.
+With auto-increment columns, this happens automatically, because the ID gets set by Spring Data with the value from the ID column.
+
+[[r2dbc.optimistic-locking]]
+=== Optimistic Locking
+
+The `@Version` annotation provides syntax similar to that of JPA in the context of R2DBC and makes sure updates are only applied to rows with a matching version.
+Therefore, the actual value of the version property is added to the update query in such a way that the update does not have any effect if another operation altered the row in the meantime.
+In that case, an `OptimisticLockingFailureException` is thrown.
+The following example shows these features:
+
+[source,java]
+----
+@Table
+class Person {
+
+  @Id Long id;
+  String firstname;
+  String lastname;
+  @Version Long version;
+}
+
+R2dbcEntityTemplate template = …;
+
+Mono<Person> daenerys = template.insert(new Person("Daenerys"));                      <1>
+
+Person other = template.select(Person.class)
+                 .matching(query(where("id").is(daenerys.getId())))
+                 .first().block();                                                    <2>
+
+daenerys.setLastname("Targaryen");
+template.update(daenerys);                                                            <3>
+
+template.update(other).subscribe(); // emits OptimisticLockingFailureException        <4>
+----
+<1> Initially insert row. `version` is set to `0`.
+<2> Load the just inserted row. `version` is still `0`.
+<3> Update the row with `version = 0`.Set the `lastname` and bump `version` to `1`.
+<4> Try to update the previously loaded row that still has `version = 0`.The operation fails with an `OptimisticLockingFailureException`, as the current `version` is `1`.
+
+[[projections.resultmapping]]
+==== Result Mapping
+
+A query method returning an Interface- or DTO projection is backed by results produced by the actual query.
+Interface projections generally rely on mapping results onto the domain type first to consider potential `@Column` type mappings and the actual projection proxy uses a potentially partially materialized entity to expose projection data.
+
+Result mapping for DTO projections depends on the actual query type.
+Derived queries use the domain type to map results, and Spring Data creates DTO instances solely from properties available on the domain type.
+Declaring properties in your DTO that are not available on the domain type is not supported.
+
+String-based queries use a different approach since the actual query, specifically the field projection, and result type declaration are close together.
+DTO projections used with query methods annotated with `@Query` map query results directly into the DTO type.
+Field mappings on the domain type are not considered.
+Using the DTO type directly, your query method can benefit from a more dynamic projection that isn't restricted to the domain model.
+
+[[r2dbc.multiple-databases]]
+== Working with multiple Databases
+
+When working with multiple, potentially different databases, your application will require a different approach to configuration.
+The provided `AbstractR2dbcConfiguration` support class assumes a single `ConnectionFactory` from which the `Dialect` gets derived.
+That being said, you need to define a few beans yourself to configure Spring Data R2DBC to work with multiple databases.
+
+R2DBC repositories require `R2dbcEntityOperations` to implement repositories.
+A simple configuration to scan for repositories without using `AbstractR2dbcConfiguration` looks like:
+
+[source,java]
+----
+@Configuration
+@EnableR2dbcRepositories(basePackages = "com.acme.mysql", entityOperationsRef = "mysqlR2dbcEntityOperations")
+static class MySQLConfiguration {
+
+    @Bean
+    @Qualifier("mysql")
+    public ConnectionFactory mysqlConnectionFactory() {
+        return …
+    }
+
+    @Bean
+    public R2dbcEntityOperations mysqlR2dbcEntityOperations(@Qualifier("mysql") ConnectionFactory connectionFactory) {
+
+        DatabaseClient databaseClient = DatabaseClient.create(connectionFactory);
+
+        return new R2dbcEntityTemplate(databaseClient, MySqlDialect.INSTANCE);
+    }
+}
+----
+
+Note that `@EnableR2dbcRepositories` allows configuration either through `databaseClientRef` or `entityOperationsRef`.
+Using various `DatabaseClient` beans is useful when connecting to multiple databases of the same type.
+When using different database systems that differ in their dialect, use `@EnableR2dbcRepositories`(entityOperationsRef = …)` instead.

+Before continuing to the JDBC or R2DBC specifics, make sure you have a sound understanding of the basic concepts explained here.
+
+The goal of the Spring Data repository abstraction is to significantly reduce the amount of boilerplate code required to implement data access layers for various persistence stores.

-[[jdbc.repositories]]
-= JDBC Repositories
-
-This chapter points out the specialties for repository support for JDBC.This builds on the core repository support explained in <<repositories>>.
-You should have a sound understanding of the basic concepts explained there.
-
-[[jdbc.why]]
-== Why Spring Data JDBC?
-
-The main persistence API for relational databases in the Java world is certainly JPA, which has its own Spring Data module.
-Why is there another one?
-
-JPA does a lot of things in order to help the developer.
-Among other things, it tracks changes to entities.
-It does lazy loading for you.
-It lets you map a wide array of object constructs to an equally wide array of database designs.
-
-This is great and makes a lot of things really easy.
-Just take a look at a basic JPA tutorial.
-But it often gets really confusing as to why JPA does a certain thing.
-Also, things that are really simple conceptually get rather difficult with JPA.
-
-Spring Data JDBC aims to be much simpler conceptually, by embracing the following design decisions:
-
-* If you load an entity, SQL statements get run.
-Once this is done, you have a completely loaded entity.
-No lazy loading or caching is done.
-
-* If you save an entity, it gets saved.
-If you do not, it does not.
-There is no dirty tracking and no session.
-
-* There is a simple model of how to map entities to tables.
-It probably only works for rather simple cases.
-If you do not like that, you should code your own strategy.
-Spring Data JDBC offers only very limited support for customizing the strategy with annotations.
-
-[[jdbc.domain-driven-design]]
-== Domain Driven Design and Relational Databases.
-
-All Spring Data modules are inspired by the concepts of "`repository`", "`aggregate`", and "`aggregate root`" from Domain Driven Design.
-These are possibly even more important for Spring Data JDBC, because they are, to some extent, contrary to normal practice when working with relational databases.
-
-An aggregate is a group of entities that is guaranteed to be consistent between atomic changes to it.
-A classic example is an `Order` with `OrderItems`.
-A property on `Order` (for example, `numberOfItems` is consistent with the actual number of `OrderItems`) remains consistent as changes are made.
-
-References across aggregates are not guaranteed to be consistent at all times.
-They are guaranteed to become consistent eventually.
-
-Each aggregate has exactly one aggregate root, which is one of the entities of the aggregate.
-The aggregate gets manipulated only through methods on that aggregate root.
-These are the atomic changes mentioned earlier.
-
-A repository is an abstraction over a persistent store that looks like a collection of all the aggregates of a certain type.
-For Spring Data in general, this means you want to have one `Repository` per aggregate root.
-In addition, for Spring Data JDBC this means that all entities reachable from an aggregate root are considered to be part of that aggregate root.
-Spring Data JDBC assumes that only the aggregate has a foreign key to a table storing non-root entities of the aggregate and no other entity points toward non-root entities.
-
-WARNING: In the current implementation, entities referenced from an aggregate root are deleted and recreated by Spring Data JDBC.
-
-You can overwrite the repository methods with implementations that match your style of working and designing your database.
-
-[[jdbc.getting-started]]
-== Getting Started
-
-An easy way to bootstrap setting up a working environment is to create a Spring-based project in https://spring.io/tools[Spring Tools] or from https://start.spring.io[Spring Initializr].
-
-First, you need to set up a running database server. Refer to your vendor documentation on how to configure your database for JDBC access.
-
-To create a Spring project in STS:
-
-. Go to File -> New -> Spring Template Project -> Simple Spring Utility Project, and press Yes when prompted. Then enter a project and a package name, such as `org.spring.jdbc.example`.
-. Add the following to the `pom.xml` files `dependencies` element:
-+
-[source,xml,subs="+attributes"]
-----
-<dependencies>
-
-  <!-- other dependency elements omitted -->
-
-  <dependency>
-    <groupId>org.springframework.data</groupId>
-    <artifactId>spring-data-jdbc</artifactId>
-    <version>{version}</version>
-  </dependency>
-
-</dependencies>
-----
-. Change the version of Spring in the pom.xml to be
-+
-[source,xml,subs="+attributes"]
-----
-<spring.framework.version>{springVersion}</spring.framework.version>
-----
-. Add the following location of the Spring Milestone repository for Maven to your `pom.xml` such that it is at the same level of your `<dependencies/>` element:
-+
-[source,xml]
-----
-<repositories>
-  <repository>
-    <id>spring-milestone</id>
-    <name>Spring Maven MILESTONE Repository</name>
-    <url>https://repo.spring.io/milestone</url>
-  </repository>
-</repositories>
-----
-
-The repository is also https://repo.spring.io/milestone/org/springframework/data/[browseable here].
-
-[[jdbc.examples-repo]]
-== Examples Repository
-
-There is a https://github.com/spring-projects/spring-data-examples[GitHub repository with several examples] that you can download and play around with to get a feel for how the library works.
-
-[[jdbc.java-config]]
-== Annotation-based Configuration
-
-The Spring Data JDBC repositories support can be activated by an annotation through Java configuration, as the following example shows:
-
-.Spring Data JDBC repositories using Java configuration

-----
-<1> `@EnableJdbcRepositories` creates implementations for interfaces derived from `Repository`
-<2> `AbstractJdbcConfiguration` provides various default beans required by Spring Data JDBC
-<3> Creates a `DataSource` connecting to a database.
-This is required by the following two bean methods.
-<4> Creates the `NamedParameterJdbcOperations` used by Spring Data JDBC to access the database.
-<5> Spring Data JDBC utilizes the transaction management provided by Spring JDBC.
-====
-
-The configuration class in the preceding example sets up an embedded HSQL database by using the `EmbeddedDatabaseBuilder` API of `spring-jdbc`.
-The `DataSource` is then used to set up `NamedParameterJdbcOperations` and a `TransactionManager`.
-We finally activate Spring Data JDBC repositories by using the `@EnableJdbcRepositories`.
-If no base package is configured, it uses the package in which the configuration class resides.
-Extending `AbstractJdbcConfiguration` ensures various beans get registered.
-Overwriting its methods can be used to customize the setup (see below).
-
-This configuration can be further simplified by using Spring Boot.
-With Spring Boot a `DataSource` is sufficient once the starter `spring-boot-starter-data-jdbc` is included in the dependencies.
-Everything else is done by Spring Boot.
-
-There are a couple of things one might want to customize in this setup.
-
-[[jdbc.dialects]]
-=== Dialects
-
-Spring Data JDBC uses implementations of the interface `Dialect` to encapsulate behavior that is specific to a database or its JDBC driver.
-By default, the `AbstractJdbcConfiguration` tries to determine the database in use and register the correct `Dialect`.
-This behavior can be changed by overwriting `jdbcDialect(NamedParameterJdbcOperations)`.
-
-If you use a database for which no dialect is available, then your application won’t startup. In that case, you’ll have to ask your vendor to provide a `Dialect` implementation. Alternatively, you can:
-
-1. Implement your own `Dialect`.
-2. Implement a `JdbcDialectProvider` returning the `Dialect`.
-3. Register the provider by creating a `spring.factories`  resource under `META-INF` and perform the registration by adding a line +
-`org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider=<fully qualified name of your JdbcDialectProvider>`
-
-[[jdbc.entity-persistence]]
-== Persisting Entities
-
-Saving an aggregate can be performed with the `CrudRepository.save(…)` method.
-If the aggregate is new, this results in an insert for the aggregate root, followed by insert statements for all directly or indirectly referenced entities.
-
-If the aggregate root is not new, all referenced entities get deleted, the aggregate root gets updated, and all referenced entities get inserted again.
-Note that whether an instance is new is part of the instance's state.
-
-NOTE: This approach has some obvious downsides.
-If only few of the referenced entities have been actually changed, the deletion and insertion is wasteful.
-While this process could and probably will be improved, there are certain limitations to what Spring Data JDBC can offer.
-It does not know the previous state of an aggregate.
-So any update process always has to take whatever it finds in the database and make sure it converts it to whatever is the state of the entity passed to the save method.

-[[jdbc.entity-persistence.types]]
-=== Supported Types in Your Entity
-
-The properties of the following types are currently supported:
-
-* All primitive types and their boxed types (`int`, `float`, `Integer`, `Float`, and so on)
-
-* Enums get mapped to their name.
-
-* `String`
-
-* `java.util.Date`, `java.time.LocalDate`, `java.time.LocalDateTime`, and `java.time.LocalTime`
-
-* Arrays and Collections of the types mentioned above can be mapped to columns of array type if your database supports that.
-
-* Anything your database driver accepts.
-
-* References to other entities.
-They are considered a one-to-one relationship, or an embedded type.
-It is optional for one-to-one relationship entities to have an `id` attribute.
-The table of the referenced entity is expected to have an additional column with a name based on the referencing entity see <<jdbc.entity-persistence.types.backrefs>>.
-Embedded entities do not need an `id`.
-If one is present it gets ignored.
-
-* `Set<some entity>` is considered a one-to-many relationship.
-The table of the referenced entity is expected to have an additional column with a name based on the referencing entity see <<jdbc.entity-persistence.types.backrefs>>.
-
-* `Map<simple type, some entity>` is considered a qualified one-to-many relationship.
-The table of the referenced entity is expected to have two additional columns: One named based on the referencing entity for the foreign key (see <<jdbc.entity-persistence.types.backrefs>>) and one with the same name and an additional `_key` suffix for the map key.
-You can change this behavior by implementing `NamingStrategy.getReverseColumnName(PersistentPropertyPathExtension path)` and `NamingStrategy.getKeyColumn(RelationalPersistentProperty property)`, respectively.
-Alternatively you may annotate the attribute with `@MappedCollection(idColumn="your_column_name", keyColumn="your_key_column_name")`
-
-* `List<some entity>` is mapped as a  `Map<Integer, some entity>`.
-
-[[jdbc.entity-persistence.types.referenced-entities]]
-==== Referenced Entities
-
-The handling of referenced entities is limited.
-This is based on the idea of aggregate roots as described above.
-If you reference another entity, that entity is, by definition, part of your aggregate.
-So, if you remove the reference, the previously referenced entity gets deleted.
-This also means references are 1-1 or 1-n, but not n-1 or n-m.
-
-If you have n-1 or n-m references, you are, by definition, dealing with two separate aggregates.
-References between those may be encoded as simple `id` values, which map properly with Spring Data JDBC.
-A better way to encode these, is to make them instances of `AggregateReference`.
-An `AggregateReference` is a wrapper around an id value which marks that value as a reference to a different aggregate.
-Also, the type of that aggregate is encoded in a type parameter.
-
-[[jdbc.entity-persistence.types.backrefs]]
-==== Back References
-
-All references in an aggregate result in a foreign key relationship in the opposite direction in the database.
-By default, the name of the foreign key column is the table name of the referencing entity.
-
-Alternatively you may choose to have them named by the entity name of the referencing entity ignoreing `@Table` annotations.
-You activate this behaviour by calling `setForeignKeyNaming(ForeignKeyNaming.IGNORE_RENAMING)` on the `RelationalMappingContext`.
-
-For `List` and `Map` references an additional column is required for holding the list index or map key. It is based on the foreign key column with an additional `_KEY` suffix.
-
-If you want a completely different way of naming these back references you may implement `NamingStrategy.getReverseColumnName(PersistentPropertyPathExtension path)` in a way that fits your needs.
-
-
-.Declaring and setting an `AggregateReference`

-
-[[jdbc.entity-persistence.naming-strategy]]
-=== `NamingStrategy`
-
-When you use the standard implementations of `CrudRepository` that Spring Data JDBC provides, they expect a certain table structure.
-You can tweak that by providing a {javadoc-base}org/springframework/data/relational/core/mapping/NamingStrategy.html[`NamingStrategy`] in your application context.
-
-[[jdbc.entity-persistence.custom-table-name]]
-=== `Custom table names`
-
-When the NamingStrategy does not matching on your database table names, you can customize the names with the {javadoc-base}org/springframework/data/relational/core/mapping/Table.html[`@Table`] annotation.
-The element `value` of this annotation provides the custom table name.
-The following example maps the `MyEntity` class to the `CUSTOM_TABLE_NAME` table in the database:
-
-====
-[source,java]
-----
-@Table("CUSTOM_TABLE_NAME")
-class MyEntity {
-    @Id
-    Integer id;
-
-    String name;
-}
-----
-====
-
-[[jdbc.entity-persistence.custom-column-name]]
-=== `Custom column names`
-
-When the NamingStrategy does not matching on your database column names, you can customize the names with the {javadoc-base}org/springframework/data/relational/core/mapping/Column.html[`@Column`] annotation.
-The element `value` of this annotation provides the custom column name.
-The following example maps the `name` property of the `MyEntity` class to the `CUSTOM_COLUMN_NAME` column in the database:
-
-====
-[source,java]
-----
-class MyEntity {
-    @Id
-    Integer id;
-
-    @Column("CUSTOM_COLUMN_NAME")
-    String name;
-}
-----
-====
-
-The {javadoc-base}org/springframework/data/relational/core/mapping/MappedCollection.html[`@MappedCollection`]
-annotation can be used on a reference type (one-to-one relationship) or on Sets, Lists, and Maps (one-to-many relationship).
-`idColumn` element of the annotation provides a custom name for the foreign key column referencing the id column in the other table.
-In the following example the corresponding table for the `MySubEntity` class has a `NAME` column, and the `CUSTOM_MY_ENTITY_ID_COLUMN_NAME` column of the `MyEntity` id for relationship reasons:
-
-====
-[source,java]
-----
-class MyEntity {
-    @Id
-    Integer id;
-
-    @MappedCollection(idColumn = "CUSTOM_MY_ENTITY_ID_COLUMN_NAME")
-    Set<MySubEntity> subEntities;
-}
-
-class MySubEntity {
-    String name;
-}
-----
-====
-
-When using `List` and `Map` you must have an additional column for the position of a dataset in the `List` or the key value of the entity in the `Map`.
-This additional column name may be customized with the `keyColumn` Element of the {javadoc-base}org/springframework/data/relational/core/mapping/MappedCollection.html[`@MappedCollection`] annotation:
-
-====
-[source,java]
-----
-class MyEntity {
-    @Id
-    Integer id;
-
-    @MappedCollection(idColumn = "CUSTOM_COLUMN_NAME", keyColumn = "CUSTOM_KEY_COLUMN_NAME")
-    List<MySubEntity> name;
-}
-
-class MySubEntity {
-    String name;
-}
-----
-====
-
-[[jdbc.entity-persistence.embedded-entities]]
-=== Embedded entities
-
-Embedded entities are used to have value objects in your java data model, even if there is only one table in your database.
-In the following example you see, that `MyEntity` is mapped with the `@Embedded` annotation.
-The consequence of this is, that in the database a table `my_entity` with the two columns `id` and `name` (from the `EmbeddedEntity` class) is expected.
-
-However, if the `name` column is actually `null` within the result set, the entire property `embeddedEntity` will be set to null according to the `onEmpty` of `@Embedded`, which ``null``s objects when all nested properties are `null`. +
-Opposite to this behavior `USE_EMPTY` tries to create a new instance using either a default constructor or one that accepts nullable parameter values from the result set.
-
-.Sample Code of embedding objects
-====
-[source,java]
-----
-class MyEntity {
-
-    @Id
-    Integer id;
-
-    @Embedded(onEmpty = USE_NULL) <1>
-    EmbeddedEntity embeddedEntity;
-}
-
-class EmbeddedEntity {
-    String name;
-}
-----
-<1> ``Null``s `embeddedEntity` if `name` in `null`.
-Use `USE_EMPTY` to instantiate `embeddedEntity` with a potential `null` value for the `name` property.
-====
-
-If you need a value object multiple times in an entity, this can be achieved with the optional `prefix` element of the `@Embedded` annotation.
-This element represents a prefix and is prepend for each column name in the embedded object.
-
-[TIP]
-====
-Make use of the shortcuts `@Embedded.Nullable` & `@Embedded.Empty` for `@Embedded(onEmpty = USE_NULL)` and `@Embedded(onEmpty = USE_EMPTY)` to reduce verbosity and simultaneously set JSR-305 `@javax.annotation.Nonnull` accordingly.
-
-[source,java]
-----
-class MyEntity {
-
-    @Id
-    Integer id;
-
-    @Embedded.Nullable <1>
-    EmbeddedEntity embeddedEntity;
-}
-----
-<1> Shortcut for `@Embedded(onEmpty = USE_NULL)`.
-====
-
-Embedded entities containing a `Collection` or a `Map` will always be considered non empty since they will at least contain the empty collection or map.
-Such an entity will therefore never be `null` even when using @Embedded(onEmpty = USE_NULL).
-
-[[jdbc.entity-persistence.state-detection-strategies]]
-include::{spring-data-commons-docs}/is-new-state-detection.adoc[leveloffset=+2]
-
-[[jdbc.entity-persistence.id-generation]]
-=== ID Generation
-
-Spring Data JDBC uses the ID to identify entities.
-The ID of an entity must be annotated with Spring Data's https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
-
-When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
-
-One important constraint is that, after saving an entity, the entity must not be new any more.
-Note that whether an entity is new is part of the entity's state.
-With auto-increment columns, this happens automatically, because the ID gets set by Spring Data with the value from the ID column.
-If you are not using auto-increment columns, you can use a `BeforeConvertCallback` to set the ID of the entity (covered later in this document).
-
-[[jdbc.entity-persistence.read-only-properties]]
-=== Read Only Properties
-
-Attributes annotated with `@ReadOnlyProperty` will not be written to the database by Spring Data JDBC, but they will be read when an entity gets loaded.
-
-Spring Data JDBC will not automatically reload an entity after writing it.
-Therefore, you have to reload it explicitly if you want to see data that was generated in the database for such columns.
-
-If the annotated attribute is an entity or collection of entities, it is represented by one or more separate rows in separate tables.
-Spring Data JDBC will not perform any insert, delete or update for these rows.
-
-[[jdbc.entity-persistence.insert-only-properties]]
-=== Insert Only Properties
-
-Attributes annotated with `@InsertOnlyProperty` will only be written to the database by Spring Data JDBC during insert operations.
-For updates these properties will be ignored.
-
-`@InsertOnlyProperty` is only supported for the aggregate root.
-
-[[jdbc.entity-persistence.optimistic-locking]]
-=== Optimistic Locking
-
-Spring Data JDBC supports optimistic locking by means of a numeric attribute that is annotated with
-https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Version.html[`@Version`] on the aggregate root.
-Whenever Spring Data JDBC saves an aggregate with such a version attribute two things happen:
-The update statement for the aggregate root will contain a where clause checking that the version stored in the database is actually unchanged.
-If this isn't the case an `OptimisticLockingFailureException` will be thrown.
-Also the version attribute gets increased both in the entity and in the database so a concurrent action will notice the change and throw an `OptimisticLockingFailureException` if applicable as described above.
-
-This process also applies to inserting new aggregates, where a `null` or `0` version indicates a new instance and the increased instance afterwards marks the instance as not new anymore, making this work rather nicely with cases where the id is generated during object construction for example when UUIDs are used.
-
-During deletes the version check also applies but no version is increased.
-
-[[jdbc.loading-aggregates]]
-== Loading Aggregates
-Spring Data JDBC offers two ways how it can load aggregates.
-The traditional and before version 3.2 the only way is really simple:
-Each query loads the aggregate roots, independently if the query is based on a `CrudRepository` method, a derived query or a annotated query.
-If the aggregate root references other entities those are loaded with separate statements.
-
-Spring Data JDBC now allows the use of _Single Query Loading_.
-With this an arbitrary number of aggregates can be fully loaded with a single SQL query.
-This should be significant more efficient, especially for complex aggregates, consisting of many entities.
-
-Currently this feature is very restricted.
-
-1. It only works for aggregates that only reference one entity collection. The plan is to remove this constraint in the future.
-
-2. The aggregate must also not use `AggregateReference` or embedded entities. The plan is to remove this constraint in the future.
-
-3. The database dialect must support it. Of the dialects provided by Spring Data JDBC all but H2 and HSQL support this. H2 and HSQL don't support analytic functions (aka windowing functions).
-
-4. It only works for the find methods in `CrudRepository`, not for derived queries and not for annotated queries. The plan is to remove this constraint in the future.
-
-5. Single Query Loading needs to be enabled in the `JdbcMappingContext`, by calling `setSingleQueryLoadingEnabled(true)`
-
-Note: Single Query Loading is to be considered experimental. We appreciate feedback on how it works for you.
-
-Note:Single Query Loading can be abbreviated as SQL, but we highly discourage that since confusion with Structured Query Language is almost guaranteed.
-
-[[jdbc.query-methods]]
-== Query Methods
-
-This section offers some specific information about the implementation and use of Spring Data JDBC.
-
-Most of the data access operations you usually trigger on a repository result in a query being run against the databases.
-Defining such a query is a matter of declaring a method on the repository interface, as the following example shows:
-
-.PersonRepository with query methods
-====
-[source,java]
-----
-interface PersonRepository extends PagingAndSortingRepository<Person, String> {
-
-  List<Person> findByFirstname(String firstname);                                   <1>
-
-  List<Person> findByFirstnameOrderByLastname(String firstname, Pageable pageable); <2>
-
-  Slice<Person> findByLastname(String lastname, Pageable pageable);                 <3>
-
-  Page<Person> findByLastname(String lastname, Pageable pageable);                  <4>
-
-  Person findByFirstnameAndLastname(String firstname, String lastname);             <5>
-
-  Person findFirstByLastname(String lastname);                                      <6>
-
-  @Query("SELECT * FROM person WHERE lastname = :lastname")
-  List<Person> findByLastname(String lastname);                                     <7>
-  @Query("SELECT * FROM person WHERE lastname = :lastname")
-  Stream<Person> streamByLastname(String lastname);                                     <8>
-
-  @Query("SELECT * FROM person WHERE username = :#{ principal?.username }")
-  Person findActiveUser();															<6>
-}
-----
-<1> The method shows a query for all people with the given `firstname`.
-The query is derived by parsing the method name for constraints that can be concatenated with `And` and `Or`.
-Thus, the method name results in a query expression of `SELECT … FROM person WHERE firstname = :firstname`.
-<2> Use `Pageable` to pass offset and sorting parameters to the database.
-<3> Return a `Slice<Person>`. Selects `LIMIT+1` rows to determine whether there's more data to consume. `ResultSetExtractor` customization is not supported.
-<4> Run a paginated query returning `Page<Person>`. Selects only data within the given page bounds and potentially a count query to determine the total count. `ResultSetExtractor` customization is not supported.
-<5> Find a single entity for the given criteria.
-It completes with `IncorrectResultSizeDataAccessException` on non-unique results.
-<6> In contrast to <3>, the first entity is always emitted even if the query yields more result documents.
-<7> The `findByLastname` method shows a query for all people with the given `lastname`.
-<8> The `streamByLastname` method returns a `Stream`, which makes values possible as soon as they are returned from the database.
-<6> You can use the Spring Expression Language to dynamically resolve parameters. In the sample, Spring Security is used to resolve the username of the current user.

-NOTE: Query derivation is limited to properties that can be used in a `WHERE` clause without using joins.
-
-[[jdbc.query-methods.strategies]]
-=== Query Lookup Strategies
-
-The JDBC module supports defining a query manually as a String in a `@Query` annotation or as named query in a property file.
-
-Deriving a query from the name of the method is is currently limited to simple properties, that means properties present in the aggregate root directly.
-Also, only select queries are supported by this approach.
-
-[[jdbc.query-methods.at-query]]
-=== Using `@Query`
-
-The following example shows how to use `@Query` to declare a query method:
-
-.Declare a query method by using @Query
-====
-[source,java]
-----
-interface UserRepository extends CrudRepository<User, Long> {
-
-  @Query("select firstName, lastName from User u where u.emailAddress = :email")
-  User findByEmailAddress(@Param("email") String email);
-}
-----
-====
-
-For converting the query result into entities the same `RowMapper` is used by default as for the queries Spring Data JDBC generates itself.
-The query you provide must match the format the `RowMapper` expects.
-Columns for all properties that are used in the constructor of an entity must be provided.
-Columns for properties that get set via setter, wither or field access are optional.
-Properties that don't have a matching column in the result will not be set.
-The query is used for populating the aggregate root, embedded entities and one-to-one relationships including arrays of primitive types which get stored and loaded as SQL-array-types.
-Separate queries are generated for maps, lists, sets and arrays of entities.
-
-NOTE: Spring fully supports Java 8’s parameter name discovery based on the `-parameters` compiler flag.
-By using this flag in your build as an alternative to debug information, you can omit the `@Param` annotation for named parameters.
-
-NOTE: Spring Data JDBC supports only named parameters.
-
-[[jdbc.query-methods.named-query]]
-=== Named Queries
-
-If no query is given in an annotation as described in the previous section Spring Data JDBC will try to locate a named query.
-There are two ways how the name of the query can be determined.
-The default is to take the _domain class_ of the query, i.e. the aggregate root of the repository, take its simple name and append the name of the method separated by a `.`.
-Alternatively the `@Query` annotation has a `name` attribute which can be used to specify the name of a query to be looked up.
-
-Named queries are expected to be provided in the property file `META-INF/jdbc-named-queries.properties` on the classpath.
-
-The location of that file may be changed by setting a value to `@EnableJdbcRepositories.namedQueriesLocation`.
-
-[[jdbc.query-methods.at-query.streaming-results]]
-==== Streaming Results
-
-When you specify Stream as the return type of a query method, Spring Data JDBC returns elements as soon as they become available.
-When dealing with large amounts of data this is suitable for reducing latency and memory requirements.
-
-The stream contains an open connection to the database.
-To avoid memory leaks, that connection needs to be closed eventually, by closing the stream.
-The recommended way to do that is a `try-with-resource clause`.
-It also means that, once the connection to the database is closed, the stream cannot obtain further elements and likely throws an exception.
-
-[[jdbc.query-methods.at-query.custom-rowmapper]]
-==== Custom `RowMapper`
-
-You can configure which `RowMapper` to use, either by using the `@Query(rowMapperClass = ....)` or by registering a `RowMapperMap` bean and registering a `RowMapper` per method return type.
-The following example shows how to register `DefaultQueryMappingConfiguration`:
-
-====
-[source,java]
-----
-@Bean
-QueryMappingConfiguration rowMappers() {
-  return new DefaultQueryMappingConfiguration()
-    .register(Person.class, new PersonRowMapper())
-    .register(Address.class, new AddressRowMapper());
-}
-----
-====
-
-When determining which `RowMapper` to use for a method, the following steps are followed, based on the return type of the method:
-
-. If the type is a simple type, no `RowMapper` is used.
-+
-Instead, the query is expected to return a single row with a single column, and a conversion to the return type is applied to that value.
-. The entity classes in the `QueryMappingConfiguration` are iterated until one is found that is a superclass or interface of the return type in question.
-The `RowMapper` registered for that class is used.
-+
-Iterating happens in the order of registration, so make sure to register more general types after specific ones.
-
-If applicable, wrapper types such as collections or `Optional` are unwrapped.
-Thus, a return type of `Optional<Person>` uses the `Person` type in the preceding process.
-
-NOTE: Using a custom `RowMapper` through `QueryMappingConfiguration`, `@Query(rowMapperClass=…)`, or a custom `ResultSetExtractor` disables Entity Callbacks and Lifecycle Events as the result mapping can issue its own events/callbacks if needed.
-
-[[jdbc.query-methods.at-query.modifying]]
-==== Modifying Query
-
-You can mark a query as being a modifying query by using the `@Modifying` on query method, as the following example shows:
-
-====
-[source,java]
-----
-@Modifying
-@Query("UPDATE DUMMYENTITY SET name = :name WHERE id = :id")
-boolean updateName(@Param("id") Long id, @Param("name") String name);
-----
-====
-
-You can specify the following return types:
-
-* `void`
-* `int` (updated record count)
-* `boolean`(whether a record was updated)
-
-Modifying queries are executed directly against the database.
-No events or callbacks get called.
-Therefore also fields with auditing annotations do not get updated if they don't get updated in the annotated query.

-[[jdbc.mybatis]]
-== MyBatis Integration
-
-The CRUD operations and query methods can be delegated to MyBatis.
-This section describes how to configure Spring Data JDBC to integrate with MyBatis and which conventions to follow to hand over the running of the queries as well as the mapping to the library.
-
-[[jdbc.mybatis.configuration]]
-=== Configuration
-
-The easiest way to properly plug MyBatis into Spring Data JDBC is by importing `MyBatisJdbcConfiguration` into you application configuration:
-
-[source,java]
-----
-@Configuration
-@EnableJdbcRepositories
-@Import(MyBatisJdbcConfiguration.class)
-class Application {
-
-  @Bean
-  SqlSessionFactoryBean sqlSessionFactoryBean() {
-    // Configure MyBatis here
-  }
-}
-----
-
-As you can see, all you need to declare is a `SqlSessionFactoryBean` as `MyBatisJdbcConfiguration` relies on a `SqlSession` bean to be available in the `ApplicationContext` eventually.
-
-[[jdbc.mybatis.conventions]]
-=== Usage conventions
-
-For each operation in `CrudRepository`, Spring Data JDBC runs multiple statements.
-If there is a https://github.com/mybatis/mybatis-3/blob/master/src/main/java/org/apache/ibatis/session/SqlSessionFactory.java[`SqlSessionFactory`] in the application context, Spring Data checks, for each step, whether the `SessionFactory` offers a statement.
-If one is found, that statement (including its configured mapping to an entity) is used.
-
-The name of the statement is constructed by concatenating the fully qualified name of the entity type with `Mapper.` and a `String` determining the kind of statement.
-For example, if an instance of `org.example.User` is to be inserted, Spring Data JDBC looks for a statement named `org.example.UserMapper.insert`.
-
-When the statement is run, an instance of [`MyBatisContext`] gets passed as an argument, which makes various arguments available to the statement.
-
-The following table describes the available MyBatis statements:
-
-[cols="default,default,default,asciidoc"]
-|===
-| Name | Purpose | CrudRepository methods that might trigger this statement | Attributes available in the `MyBatisContext`
-
-| `insert` | Inserts a single entity. This also applies for entities referenced by the aggregate root. | `save`, `saveAll`. |
-`getInstance`: the instance to be saved
-
-`getDomainType`: The type of the entity to be saved.
-
-`get(<key>)`: ID of the referencing entity, where `<key>` is the name of the back reference column provided by the `NamingStrategy`.
-
-
-| `update` | Updates a single entity. This also applies for entities referenced by the aggregate root. | `save`, `saveAll`.|
-`getInstance`: The instance to be saved
-
-`getDomainType`: The type of the entity to be saved.
-
-| `delete` | Deletes a single entity. | `delete`, `deleteById`.|
-`getId`: The ID of the instance to be deleted
-
-`getDomainType`: The type of the entity to be deleted.
-
-| `deleteAll-<propertyPath>` | Deletes all entities referenced by any aggregate root of the type used as prefix with the given property path.
-Note that the type used for prefixing the statement name is the name of the aggregate root, not the one of the entity to be deleted. | `deleteAll`.|
-
-`getDomainType`: The types of the entities to be deleted.
-
-| `deleteAll` | Deletes all aggregate roots of the type used as the prefix | `deleteAll`.|
-
-`getDomainType`: The type of the entities to be deleted.
-
-| `delete-<propertyPath>` | Deletes all entities referenced by an aggregate root with the given propertyPath | `deleteById`.|
-
-`getId`: The ID of the aggregate root for which referenced entities are to be deleted.
-
-`getDomainType`: The type of the entities to be deleted.
-
-| `findById` | Selects an aggregate root by ID | `findById`.|
-
-`getId`: The ID of the entity to load.
-
-`getDomainType`: The type of the entity to load.
-
-| `findAll` | Select all aggregate roots | `findAll`.|
-
-`getDomainType`: The type of the entity to load.
-
-| `findAllById` | Select a set of aggregate roots by ID values | `findAllById`.|
-
-`getId`: A list of ID values of the entities to load.
-
-`getDomainType`: The type of the entity to load.
-
-| `findAllByProperty-<propertyName>` | Select a set of entities that is referenced by another entity. The type of the referencing entity is used for the prefix. The referenced entities type is used as the suffix. _This method is deprecated. Use `findAllByPath` instead_ | All `find*` methods. If no query is defined for `findAllByPath`|
-
-`getId`: The ID of the entity referencing the entities to be loaded.
-
-`getDomainType`: The type of the entity to load.
-
-
-| `findAllByPath-<propertyPath>` | Select a set of entities that is referenced by another entity via a property path. | All `find*` methods.|
-
-`getIdentifier`: The `Identifier` holding the id of the aggregate root plus the keys and list indexes of all path elements.
-
-`getDomainType`: The type of the entity to load.
-
-| `findAllSorted` | Select all aggregate roots, sorted | `findAll(Sort)`.|
-
-`getSort`: The sorting specification.
-
-| `findAllPaged` | Select a page of aggregate roots, optionally sorted | `findAll(Page)`.|
-
-`getPageable`: The paging specification.
-
-| `count` | Count the number of aggregate root of the type used as prefix | `count` |
-
-`getDomainType`: The type of aggregate roots to count.
-|===
-
-[[jdbc.events]]
-== Lifecycle Events
-
-Spring Data JDBC publishes lifecycle events to `ApplicationListener` objects, typically beans in the application context.
-Events are notifications about a certain lifecycle phase.
-In contrast to entity callbacks, events are intended for notification. Transactional listeners will receive events when the transaction completes.
-Events and callbacks get only triggered for aggregate roots.
-If you want to process non-root entities, you need to do that through a listener for the containing aggregate root.
-
-Entity lifecycle events can be costly, and you may notice a change in the performance profile when loading large result sets.
-You can disable lifecycle events on the link:{javadoc-base}org/springframework/data/jdbc/core/JdbcAggregateTemplate.html#setEntityLifecycleEventsEnabled(boolean)[Template API].
-
-For example, the following listener gets invoked before an aggregate gets saved:
-
-====
-[source,java]
-----
-@Bean
-ApplicationListener<BeforeSaveEvent<Object>> loggingSaves() {
-
-	return event -> {
-
-		Object entity = event.getEntity();
-		LOG.info("{} is getting saved.", entity);
-	};
-}
-----
-====
-
-If you want to handle events only for a specific domain type you may derive your listener from `AbstractRelationalEventListener` and overwrite one or more of the `onXXX` methods, where `XXX` stands for an event type.
-Callback methods will only get invoked for events related to the domain type and their subtypes, therefore you don't require further casting.
-
-====
-[source,java]
-----
-class PersonLoadListener extends AbstractRelationalEventListener<Person> {
-
-	@Override
-	protected void onAfterLoad(AfterLoadEvent<Person> personLoad) {
-		LOG.info(personLoad.getEntity());
-	}
-}
-----
-====
-
-The following table describes the available events. For more details about the exact relation between process steps see the link:#jdbc.entity-callbacks[description of available callbacks] which map 1:1 to events.
-
-.Available events
-|===
-| Event | When It Is Published
-
-| {javadoc-base}org/springframework/data/relational/core/mapping/event/BeforeDeleteEvent.html[`BeforeDeleteEvent`]
-| Before an aggregate root gets deleted.
-
-| {javadoc-base}org/springframework/data/relational/core/mapping/event/AfterDeleteEvent.html[`AfterDeleteEvent`]
-| After an aggregate root gets deleted.
-
-| {javadoc-base}/org/springframework/data/relational/core/mapping/event/BeforeConvertEvent.html[`BeforeConvertEvent`]
-| Before an aggregate root gets converted into a plan for executing SQL statements, but after the decision was made if the aggregate is new or not, i.e. if an update or an insert is in order.
-
-| {javadoc-base}/org/springframework/data/relational/core/mapping/event/BeforeSaveEvent.html[`BeforeSaveEvent`]
-| Before an aggregate root gets saved (that is, inserted or updated but after the decision about whether if it gets inserted or updated was made).
-
-| {javadoc-base}org/springframework/data/relational/core/mapping/event/AfterSaveEvent.html[`AfterSaveEvent`]
-| After an aggregate root gets saved (that is, inserted or updated).
-
-| {javadoc-base}org/springframework/data/relational/core/mapping/event/AfterConvertEvent.html[`AfterConvertEvent`]
-| After an aggregate root gets created from a database `ResultSet` and all its properties get set.
-|===
-
-WARNING: Lifecycle events depend on an `ApplicationEventMulticaster`, which in case of the `SimpleApplicationEventMulticaster` can be configured with a `TaskExecutor`, and therefore gives no guarantees when an Event is processed.
-
-
-[[jdbc.entity-callbacks]]
-=== Store-specific EntityCallbacks
-
-Spring Data JDBC uses the `EntityCallback` API for its auditing support and reacts on the callbacks listed in the following table.
-
-.Process Steps and Callbacks of the Different Processes performed by Spring Data JDBC.
-|===
-| Process | `EntityCallback` / Process Step | Comment
-
-.3+| Delete | {javadoc-base}org/springframework/data/relational/core/mapping/event/BeforeDeleteCallback.html[`BeforeDeleteCallback`]
-| Before the actual deletion.
-
-2+| The aggregate root and all the entities of that aggregate get removed from the database.
-
-| {javadoc-base}org/springframework/data/relational/core/mapping/event/AfterDeleteCallback.html[`AfterDeleteCallback`]
-| After an aggregate gets deleted.
-
-.6+| Save 2+| Determine if an insert or an update of the aggregate is to be performed dependen on if it is new or not.
-
-| {javadoc-base}/org/springframework/data/relational/core/mapping/event/BeforeConvertCallback.html[`BeforeConvertCallback`]
-| This is the correct callback if you want to set an id programmatically. In the previous step new aggregates got detected as such and a Id generated in this step would be used in the following step.
-
-2+| Convert the aggregate to a aggregate change, it is a sequence of SQL statements to be executed against the database. In this step the decision is made if an Id is provided by the aggregate or if the Id is still empty and is expected to be generated by the database.
-
-| {javadoc-base}/org/springframework/data/relational/core/mapping/event/BeforeSaveCallback.html[`BeforeSaveCallback`]
-| Changes made to the aggregate root may get considered, but the decision if an id value will be sent to the database is already made in the previous step.
-Do not use this for creating Ids for new aggregates. Use `BeforeConvertCallback` instead.
-
-2+| The SQL statements determined above get executed against the database.
-
-| {javadoc-base}org/springframework/data/relational/core/mapping/event/AfterSaveCallback.html[`AfterSaveCallback`]
-| After an aggregate root gets saved (that is, inserted or updated).
-
-.2+| Load 2+| Load the aggregate using 1 or more SQL queries. Construct the aggregate from the resultset.
-
-| {javadoc-base}org/springframework/data/relational/core/mapping/event/AfterConvertCallback.html[`AfterConvertCallback`]
-|
-|===
-
-We encourage the use of callbacks over events since they support the use of immutable classes and therefore are more powerful and versatile than events.
-
-include::{spring-data-commons-docs}/entity-callbacks.adoc[leveloffset=+1]
-
-include::jdbc-custom-conversions.adoc[]
-
-[[jdbc.logging]]
-== Logging
-
-Spring Data JDBC does little to no logging on its own.
-Instead, the mechanics of `JdbcTemplate` to issue SQL statements provide logging.
-Thus, if you want to inspect what SQL statements are run, activate logging for Spring's {spring-framework-docs}/data-access.html#jdbc-JdbcTemplate[`NamedParameterJdbcTemplate`] or https://www.mybatis.org/mybatis-3/logging.html[MyBatis].
-
-[[jdbc.transactions]]
-== Transactionality
-
-The methods of `CrudRepository` instances are transactional by default.
-For reading operations, the transaction configuration `readOnly` flag is set to `true`.
-All others are configured with a plain `@Transactional` annotation so that default transaction configuration applies.
-For details, see the Javadoc of link:{javadoc-base}org/springframework/data/jdbc/repository/support/SimpleJdbcRepository.html[`SimpleJdbcRepository`].
-If you need to tweak transaction configuration for one of the methods declared in a repository, redeclare the method in your repository interface, as follows:
-
-.Custom transaction configuration for CRUD
-====
-[source,java]
-----
-interface UserRepository extends CrudRepository<User, Long> {
-
-  @Override
-  @Transactional(timeout = 10)
-  List<User> findAll();
-
-  // Further query method declarations
-}
-----
-====
-
-The preceding causes the `findAll()` method to be run with a timeout of 10 seconds and without the `readOnly` flag.
-
-Another way to alter transactional behavior is by using a facade or service implementation that typically covers more than one repository.
-Its purpose is to define transactional boundaries for non-CRUD operations.
-The following example shows how to create such a facade:
-
-.Using a facade to define transactions for multiple repository calls
-====
-[source,java]
-----
-@Service
-public class UserManagementImpl implements UserManagement {
-
-  private final UserRepository userRepository;
-  private final RoleRepository roleRepository;
-
-  UserManagementImpl(UserRepository userRepository,
-    RoleRepository roleRepository) {
-    this.userRepository = userRepository;
-    this.roleRepository = roleRepository;
-  }
-
-  @Transactional
-  public void addRoleToAllUsers(String roleName) {
-
-    Role role = roleRepository.findByName(roleName);
-
-    for (User user : userRepository.findAll()) {
-      user.addRole(role);
-      userRepository.save(user);
-    }
-}
-----
-====
-
-The preceding example causes calls to `addRoleToAllUsers(…)` to run inside a transaction (participating in an existing one or creating a new one if none are already running).
-The transaction configuration for the repositories is neglected, as the outer transaction configuration determines the actual repository to be used.
-Note that you have to explicitly activate `<tx:annotation-driven />` or use `@EnableTransactionManagement` to get annotation-based configuration for facades working.
-Note that the preceding example assumes you use component scanning.
-
-[[jdbc.transaction.query-methods]]
-=== Transactional Query Methods
-
-To let your query methods be transactional, use `@Transactional` at the repository interface you define, as the following example shows:
-
-.Using @Transactional at query methods
-====
-[source,java]
-----
-@Transactional(readOnly = true)
-interface UserRepository extends CrudRepository<User, Long> {
-
-  List<User> findByLastname(String lastname);
-
-  @Modifying
-  @Transactional
-  @Query("delete from User u where u.active = false")
-  void deleteInactiveUsers();
-}
-----
-====
-
-Typically, you want the `readOnly` flag to be set to true, because most of the query methods only read data.
-In contrast to that, `deleteInactiveUsers()` uses the `@Modifying` annotation and overrides the transaction configuration.
-Thus, the method is with the `readOnly` flag set to `false`.
-
-NOTE: It is highly recommended to make query methods transactional. These methods might execute more then one query in order to populate an entity.
-Without a common transaction Spring Data JDBC executes the queries in different connections.
-This may put excessive strain on the connection pool and might even lead to dead locks when multiple methods request a fresh connection while holding on to one.
-
-NOTE: It is definitely reasonable to mark read-only queries as such by setting the `readOnly` flag.
-This does not, however, act as a check that you do not trigger a manipulating query (although some databases reject `INSERT` and `UPDATE` statements inside a read-only transaction).
-Instead, the `readOnly` flag is propagated as a hint to the underlying JDBC driver for performance optimizations.
-
-include::{spring-data-commons-docs}/auditing.adoc[leveloffset=+1]
-
-[[jdbc.auditing]]
-== JDBC Auditing
-
-In order to activate auditing, add `@EnableJdbcAuditing` to your configuration, as the following example shows:
-
-.Activating auditing with Java configuration
-====
-[source,java]
-----
-@Configuration
-@EnableJdbcAuditing
-class Config {
-
-  @Bean
-  AuditorAware<AuditableUser> auditorProvider() {
-    return new AuditorAwareImpl();
-  }
-}
-----
-====
-
-If you expose a bean of type `AuditorAware` to the `ApplicationContext`, the auditing infrastructure automatically picks it up and uses it to determine the current user to be set on domain types.
-If you have multiple implementations registered in the `ApplicationContext`, you can select the one to be used by explicitly setting the `auditorAwareRef` attribute of `@EnableJdbcAuditing`.
-
-[[jdbc.locking]]
-== JDBC Locking
-
-Spring Data JDBC supports locking on derived query methods.
-To enable locking on a given derived query method inside a repository, you annotate it with `@Lock`.
-The required value of type `LockMode` offers two values: `PESSIMISTIC_READ` which guarantees that the data you are reading doesn't get modified and `PESSIMISTIC_WRITE` which obtains a lock to modify the data.
-Some databases do not make this distinction.
-In that cases both modes are equivalent of `PESSIMISTIC_WRITE`.
-
-.Using @Lock on derived query method
-====
-[source,java]
-----
-interface UserRepository extends CrudRepository<User, Long> {
-
-  @Lock(LockMode.PESSIMISTIC_READ)
-  List<User> findByLastname(String lastname);
-}
-----
-====
-
-As you can see above, the method `findByLastname(String lastname)` will be executed with a pessimistic read lock. If you are using a databse with the MySQL Dialect this will result for example in the following query:
-
-.Resulting Sql query for MySQL dialect
-====
-[source,sql]
-----
-Select * from user u where u.lastname = lastname LOCK IN SHARE MODE
-----
-====
-
-Alternative to `LockMode.PESSIMISTIC_READ` you can use `LockMode.PESSIMISTIC_WRITE`.

-= Preface
-
-The Spring Data JDBC project applies core Spring concepts to the development of solutions that use JDBC databases aligned with <<jdbc.domain-driven-design,Domain-driven design principles>>.
-We provide a "`template`" as a high-level abstraction for storing and querying aggregates.
-
-This document is the reference guide for Spring Data JDBC Support.
-It explains the concepts and semantics and syntax..
-
-This section provides some basic introduction.
-The rest of the document refers only to Spring Data JDBC features and assumes the user is familiar with SQL and Spring concepts.
-
-[[get-started:first-steps:spring]]
-== Learning Spring
-
-Spring Data uses Spring framework's {spring-framework-docs}/core.html[core] functionality, including:
-
-* {spring-framework-docs}/core.html#beans[IoC] container
-* {spring-framework-docs}/core.html#validation[type conversion system]
-* {spring-framework-docs}/core.html#expressions[expression language]
-* {spring-framework-docs}/integration.html#jmx[JMX integration]
-* {spring-framework-docs}/data-access.html#dao-exceptions[DAO exception hierarchy].
-
-While you need not know the Spring APIs, understanding the concepts behind them is important.
-At a minimum, the idea behind Inversion of Control (IoC) should be familiar, and you should be familiar with whatever IoC container you choose to use.
-
-The core functionality of the JDBC Aggregate support can be used directly, with no need to invoke the IoC services of the Spring Container.
-This is much like `JdbcTemplate`, which can be used "'standalone'" without any other services of the Spring container.
-To leverage all the features of Spring Data JDBC, such as the repository support, you need to configure some parts of the library to use Spring.
-
-To learn more about Spring, you can refer to the comprehensive documentation that explains the Spring Framework in detail.
-There are a lot of articles, blog entries, and books on the subject.
-See the Spring framework https://spring.io/docs[home page] for more information.
-
-[[requirements]]
-== Requirements
-
-The Spring Data JDBC binaries require JDK level 8.0 and above and https://spring.io/docs[Spring Framework] {springVersion} and above.
-
-In terms of databases, Spring Data JDBC requires a <<jdbc.dialects,dialect>> to abstract common SQL functionality over vendor-specific flavours.
-Spring Data JDBC includes direct support for the following databases:
-
-* DB2
-* H2
-* HSQLDB
-* MariaDB
-* Microsoft SQL Server
-* MySQL
-* Oracle
-* Postgres
-
-If you use a different database then your application won’t startup. The <<jdbc.dialects,dialect>> section contains further detail on how to proceed in such case.
-

-<4> Creates the `NamedParameterJdbcOperations` used by Spring Data JDBC to access the database.
-<5> Spring Data JDBC utilizes the transaction management provided by Spring JDBC.
-
-The configuration class in the preceding example sets up an embedded HSQL database by using the `EmbeddedDatabaseBuilder` API of `spring-jdbc`.
-The `DataSource` is then used to set up `NamedParameterJdbcOperations` and a `TransactionManager`.
-We finally activate Spring Data JDBC repositories by using the `@EnableJdbcRepositories`.
-If no base package is configured, it uses the package in which the configuration class resides.
-Extending `AbstractJdbcConfiguration` ensures various beans get registered.
-Overwriting its methods can be used to customize the setup (see below).
-
-This configuration can be further simplified by using Spring Boot.
-With Spring Boot a `DataSource` is sufficient once the starter `spring-boot-starter-data-jdbc` is included in the dependencies.
-Everything else is done by Spring Boot.
-
-There are a couple of things one might want to customize in this setup.
-
-[[jdbc.dialects]]
-== Dialects
-
-Spring Data JDBC uses implementations of the interface `Dialect` to encapsulate behavior that is specific to a database or its JDBC driver.
-By default, the `AbstractJdbcConfiguration` tries to determine the database in use and register the correct `Dialect`.
-This behavior can be changed by overwriting `jdbcDialect(NamedParameterJdbcOperations)`.
-
-If you use a database for which no dialect is available, then your application won’t startup. In that case, you’ll have to ask your vendor to provide a `Dialect` implementation. Alternatively, you can:
-
-1. Implement your own `Dialect`.
-2. Implement a `JdbcDialectProvider` returning the `Dialect`.
-3. Register the provider by creating a `spring.factories`  resource under `META-INF` and perform the registration by adding a line +
-`org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider=<fully qualified name of your JdbcDialectProvider>`

-}
-----

-    }

-----
-
-NOTE: In previous versions of Spring Data JDBC it was recommended to directly overwrite `AbstractJdbcConfiguration.jdbcCustomConversions()`.
-This is no longer necessary or even recommended, since that method assembles conversions intended for all databases, conversions registered by the `Dialect` used and conversions registered by the user.
-If you are migrating from an older version of Spring Data JDBC and have `AbstractJdbcConfiguration.jdbcCustomConversions()` overwritten conversions from your `Dialect` will not get registered.
-
-[[jdbc.custom-converters.jdbc-value]]
-== JdbcValue
-
-Value conversion uses `JdbcValue` to enrich values propagated to JDBC operations with a `java.sql.Types` type.
-Register a custom write converter if you need to specify a JDBC-specific type instead of using type derivation.
-This converter should convert the value to `JdbcValue` which has a field for the value and for the actual `JDBCType`.

-== ID Generation
+[[jdbc.loading-aggregates]]
+== Loading Aggregates
 
-Spring Data JDBC uses the ID to identify entities.
-The ID of an entity must be annotated with Spring Data's https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
+Spring Data JDBC offers two ways how it can load aggregates:
 
-When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
+. The traditional and before version 3.2 the only way is really simple:
+Each query loads the aggregate roots, independently if the query is based on a `CrudRepository` method, a derived query or a annotated query.
+If the aggregate root references other entities those are loaded with separate statements.
 
-One important constraint is that, after saving an entity, the entity must not be new any more.
-Note that whether an entity is new is part of the entity's state.
-With auto-increment columns, this happens automatically, because the ID gets set by Spring Data with the value from the ID column.
-If you are not using auto-increment columns, you can use a `BeforeConvertCallback` to set the ID of the entity (covered later in this document).

+With this an arbitrary number of aggregates can be fully loaded with a single SQL query.
+This should be significant more efficient, especially for complex aggregates, consisting of many entities.

-== Optimistic Locking
+1. It only works for aggregates that only reference one entity collection.The plan is to remove this constraint in the future.
+
+2. The aggregate must also not use `AggregateReference` or embedded entities.The plan is to remove this constraint in the future.
+
+3. The database dialect must support it.Of the dialects provided by Spring Data JDBC all but H2 and HSQL support this.H2 and HSQL don't support analytic functions (aka windowing functions).
+
+4. It only works for the find methods in `CrudRepository`, not for derived queries and not for annotated queries.The plan is to remove this constraint in the future.
 
-Spring Data JDBC supports optimistic locking by means of a numeric attribute that is annotated with
-https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Version.html[`@Version`] on the aggregate root.
-Whenever Spring Data JDBC saves an aggregate with such a version attribute two things happen:
-The update statement for the aggregate root will contain a where clause checking that the version stored in the database is actually unchanged.
-If this isn't the case an `OptimisticLockingFailureException` will be thrown.
-Also the version attribute gets increased both in the entity and in the database so a concurrent action will notice the change and throw an `OptimisticLockingFailureException` if applicable as described above.
+5. Single Query Loading needs to be enabled in the `JdbcMappingContext`, by calling `setSingleQueryLoadingEnabled(true)`
 
-This process also applies to inserting new aggregates, where a `null` or `0` version indicates a new instance and the increased instance afterwards marks the instance as not new anymore, making this work rather nicely with cases where the id is generated during object construction for example when UUIDs are used.
+NOTE: Single Query Loading is to be considered experimental.
+We appreciate feedback on how it works for you.
+
+NOTE: While Single Query Loading can be abbreviated as SQL, but we highly discourage doing so since confusion with Structured Query Language is almost guaranteed.

+        return new DataSourceTransactionManager(dataSource);
+    }
+}
+----
+
+<1> `@EnableJdbcRepositories` creates implementations for interfaces derived from `Repository`
+<2> `AbstractJdbcConfiguration` provides various default beans required by Spring Data JDBC
+<3> Creates a `DataSource` connecting to a database.
+This is required by the following two bean methods.
+<4> Creates the `NamedParameterJdbcOperations` used by Spring Data JDBC to access the database.
+<5> Spring Data JDBC utilizes the transaction management provided by Spring JDBC.
+
+The configuration class in the preceding example sets up an embedded HSQL database by using the `EmbeddedDatabaseBuilder` API of `spring-jdbc`.
+The `DataSource` is then used to set up `NamedParameterJdbcOperations` and a `TransactionManager`.
+We finally activate Spring Data JDBC repositories by using the `@EnableJdbcRepositories`.
+If no base package is configured, it uses the package in which the configuration class resides.
+Extending `AbstractJdbcConfiguration` ensures various beans get registered.
+Overwriting its methods can be used to customize the setup (see below).
+
+This configuration can be further simplified by using Spring Boot.
+With Spring Boot a `DataSource` is sufficient once the starter `spring-boot-starter-data-jdbc` is included in the dependencies.
+Everything else is done by Spring Boot.
+
+There are a couple of things one might want to customize in this setup.
+
+[[jdbc.dialects]]
+== Dialects
+
+Spring Data JDBC uses implementations of the interface `Dialect` to encapsulate behavior that is specific to a database or its JDBC driver.
+By default, the `AbstractJdbcConfiguration` attempts to determine the dialect from the database configuration by obtaining a connection and registering the correct `Dialect`.
+You override `AbstractJdbcConfiguration.jdbcDialect(NamedParameterJdbcOperations)` to customize dialect selection.
+
+If you use a database for which no dialect is available, then your application won’t start up.
+In that case, you’ll have to ask your vendor to provide a `Dialect` implementation.
+Alternatively, you can implement your own `Dialect`.
+
+[TIP]
+====
+Dialects are resolved by {spring-data-jdbc-javadoc}/org/springframework/data/jdbc/repository/config/DialectResolver.html[`DialectResolver`] from a `JdbcOperations` instance, typically by inspecting `Connection.getMetaData()`.
++ You can let Spring auto-discover your `JdbcDialect` by registering a class that implements `org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider` through `META-INF/spring.factories`.
+`DialectResolver` discovers dialect provider implementations from the class path using Spring's `SpringFactoriesLoader`.
+To do so:
+
+. Implement your own `Dialect`.
+. Implement a `JdbcDialectProvider` returning the `Dialect`.
+. Register the provider by creating a `spring.factories`  resource under `META-INF` and perform the registration by adding a line +
+`org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider=<fully qualified name of your JdbcDialectProvider>`

-= JDBC Locking
-
-Spring Data JDBC supports locking on derived query methods.
-To enable locking on a given derived query method inside a repository, you annotate it with `@Lock`.
-The required value of type `LockMode` offers two values: `PESSIMISTIC_READ` which guarantees that the data you are reading doesn't get modified and `PESSIMISTIC_WRITE` which obtains a lock to modify the data.
-Some databases do not make this distinction.
-In that cases both modes are equivalent of `PESSIMISTIC_WRITE`.
-
-.Using @Lock on derived query method
-[source,java]
-----
-interface UserRepository extends CrudRepository<User, Long> {
-
-  @Lock(LockMode.PESSIMISTIC_READ)
-  List<User> findByLastname(String lastname);
-}
-----
-
-As you can see above, the method `findByLastname(String lastname)` will be executed with a pessimistic read lock. If you are using a databse with the MySQL Dialect this will result for example in the following query:
-
-.Resulting Sql query for MySQL dialect
-[source,sql]
-----
-Select * from user u where u.lastname = lastname LOCK IN SHARE MODE

-
-Alternative to `LockMode.PESSIMISTIC_READ` you can use `LockMode.PESSIMISTIC_WRITE`.

-[[jdbc.entity-persistence.embedded-entities]]
-== Embedded entities
+There are a couple of things to notice here: `Boolean` and `String` are both simple types hence Spring Data requires a hint in which direction this converter should apply (reading or writing).
+By annotating this converter with `@WritingConverter` you instruct Spring Data to write every `Boolean` property as `String` in the database.
 
-Embedded entities are used to have value objects in your java data model, even if there is only one table in your database.
-In the following example you see, that `MyEntity` is mapped with the `@Embedded` annotation.
-The consequence of this is, that in the database a table `my_entity` with the two columns `id` and `name` (from the `EmbeddedEntity` class) is expected.
+[[custom-converters.reader]]
+=== Reading by Using a Spring Converter
 
-However, if the `name` column is actually `null` within the result set, the entire property `embeddedEntity` will be set to null according to the `onEmpty` of `@Embedded`, which ``null``s objects when all nested properties are `null`. +
-Opposite to this behavior `USE_EMPTY` tries to create a new instance using either a default constructor or one that accepts nullable parameter values from the result set.
+The following example shows an implementation of a `Converter` that converts from a `String` to a `Boolean` value:
 
-.Sample Code of embedding objects
-====
 [source,java]
 ----
-class MyEntity {
-
-    @Id
-    Integer id;
+@ReadingConverter
+public class StringToBooleanConverter implements Converter<String, Boolean> {
 
-    @Embedded(onEmpty = USE_NULL) <1>
-    EmbeddedEntity embeddedEntity;
-}
-
-class EmbeddedEntity {
-    String name;
+    @Override
+    public Boolean convert(String source) {
+        return source != null && source.equalsIgnoreCase("T") ? Boolean.TRUE : Boolean.FALSE;
+    }
 }
 ----
 
-<1> ``Null``s `embeddedEntity` if `name` in `null`.
-Use `USE_EMPTY` to instantiate `embeddedEntity` with a potential `null` value for the `name` property.
-====
-
-If you need a value object multiple times in an entity, this can be achieved with the optional `prefix` element of the `@Embedded` annotation.
-This element represents a prefix and is prepend for each column name in the embedded object.
+There are a couple of things to notice here: `String` and `Boolean` are both simple types hence Spring Data requires a hint in which direction this converter should apply (reading or writing).
+By annotating this converter with `@ReadingConverter` you instruct Spring Data to convert every `String` value from the database that should be assigned to a `Boolean` property.
 
-[TIP]
-====
-Make use of the shortcuts `@Embedded.Nullable` & `@Embedded.Empty` for `@Embedded(onEmpty = USE_NULL)` and `@Embedded(onEmpty = USE_EMPTY)` to reduce verbosity and simultaneously set JSR-305 `@javax.annotation.Nonnull` accordingly.

-====
-
-Embedded entities containing a `Collection` or a `Map` will always be considered non empty since they will at least contain the empty collection or map.

-== Read Only Properties
-
-Attributes annotated with `@ReadOnlyProperty` will not be written to the database by Spring Data JDBC, but they will be read when an entity gets loaded.
-
-Spring Data JDBC will not automatically reload an entity after writing it.
-Therefore, you have to reload it explicitly if you want to see data that was generated in the database for such columns.
-
-If the annotated attribute is an entity or collection of entities, it is represented by one or more separate rows in separate tables.
-Spring Data JDBC will not perform any insert, delete or update for these rows.
-
-[[jdbc.entity-persistence.insert-only-properties]]
-== Insert Only Properties
+NOTE: In previous versions of Spring Data JDBC it was recommended to directly overwrite `AbstractJdbcConfiguration.jdbcCustomConversions()`.
+This is no longer necessary or even recommended, since that method assembles conversions intended for all databases, conversions registered by the `Dialect` used and conversions registered by the user.
+If you are migrating from an older version of Spring Data JDBC and have `AbstractJdbcConfiguration.jdbcCustomConversions()` overwritten conversions from your `Dialect` will not get registered.
 
-Attributes annotated with `@InsertOnlyProperty` will only be written to the database by Spring Data JDBC during insert operations.
-For updates these properties will be ignored.
+[[jdbc.custom-converters.jdbc-value]]
+=== JdbcValue
 
-`@InsertOnlyProperty` is only supported for the aggregate root.
+Value conversion uses `JdbcValue` to enrich values propagated to JDBC operations with a `java.sql.Types` type.
+Register a custom write converter if you need to specify a JDBC-specific type instead of using type derivation.
+This converter should convert the value to `JdbcValue` which has a field for the value and for the actual `JDBCType`.

+== JDBC Locking
+
+Spring Data JDBC supports locking on derived query methods.
+To enable locking on a given derived query method inside a repository, you annotate it with `@Lock`.
+The required value of type `LockMode` offers two values: `PESSIMISTIC_READ` which guarantees that the data you are reading doesn't get modified and `PESSIMISTIC_WRITE` which obtains a lock to modify the data.
+Some databases do not make this distinction.
+In that cases both modes are equivalent of `PESSIMISTIC_WRITE`.
+
+.Using @Lock on derived query method
+[source,java]
+----
+interface UserRepository extends CrudRepository<User, Long> {
+
+  @Lock(LockMode.PESSIMISTIC_READ)
+  List<User> findByLastname(String lastname);
+}
+----
+
+As you can see above, the method `findByLastname(String lastname)` will be executed with a pessimistic read lock.
+If you are using a databse with the MySQL Dialect this will result for example in the following query:

 === Mapping Annotation Overview
 
-The `MappingR2dbcConverter` can use metadata to drive the mapping of objects to rows.
-The following annotations are available:
-
-* `@Id`: Applied at the field level to mark the primary key.
-* `@Table`: Applied at the class level to indicate this class is a candidate for mapping to the database.
-You can specify the name of the table where the database is stored.
-* `@Transient`: By default, all fields are mapped to the row.
-This annotation excludes the field where it is applied from being stored in the database.
-Transient properties cannot be used within a persistence constructor as the converter cannot materialize a value for the constructor argument.
-* `@PersistenceConstructor`: Marks a given constructor -- even a package protected one -- to use when instantiating the object from the database.
-Constructor arguments are mapped by name to the values in the retrieved row.
-* `@Value`: This annotation is part of the Spring Framework.
-Within the mapping framework it can be applied to constructor arguments.
-This lets you use a Spring Expression Language statement to transform a key’s value retrieved in the database before it is used to construct a domain object.
-In order to reference a column of a given row one has to use expressions like: `@Value("#root.myProperty")` where root refers to the root of the given `Row`.
-* `@Column`: Applied at the field level to describe the name of the column as it is represented in the row, letting the name be different from the field name of the class.
-Names specified with a `@Column` annotation are always quoted when used in SQL statements.
-For most databases, this means that these names are case-sensitive.
-It also means that you can use special characters in these names.
-However, this is not recommended, since it may cause problems with other tools.
-* `@Version`: Applied at field level is used for optimistic locking and checked for modification on save operations.
-The value is `null` (`zero` for primitive types) is considered as marker for entities to be new.
-The initially stored value is `zero` (`one` for primitive types).
-The version gets incremented automatically on every update.
-See xref:r2dbc/repositories.adoc#r2dbc.optimistic-locking[Optimistic Locking] for further reference.

 The mapping metadata infrastructure is defined in the separate `spring-data-commons` project that is technology-agnostic.
 Specific subclasses are used in the R2DBC support to support annotation based metadata.
 Other strategies can also be put in place (if there is demand).

-* If the Java type has a property whose name matches the given field of the input row, then its property information is used to select the appropriate constructor parameter to which to pass the input field value.
-This works only if the parameter name information is present in the Java `.class` files, which you can achieve by compiling the source with debug information or using the `-parameters` command-line switch for `javac` in Java 8.
-* Otherwise, a `MappingException` is thrown to indicate that the given constructor parameter could not be bound.

-= Query By Example
-
-Spring Data R2DBC also lets you use xref:query-by-example.adoc[Query By Example] to fashion queries.
-This technique allows you to use a "probe" object.
-Essentially, any field that isn't empty or `null` will be used to match.
-
-Here's an example:
-
-[source,java,indent=0]
-----
-include::example$r2dbc/QueryByExampleTests.java[tag=example]
-----
-
-<1> Create a domain object with the criteria (`null` fields will be ignored).
-<2> Using the domain object, create an `Example`.
-<3> Through the `R2dbcRepository`, execute query (use `findOne` for a `Mono`).
-
-This illustrates how to craft a simple probe using a domain object.
-In this case, it will query based on the `Employee` object's `name` field being equal to `Frodo`.
-`null` fields are ignored.
-
-[source,java,indent=0]
-----
-include::example$r2dbc/QueryByExampleTests.java[tag=example-2]
-----
-
-<1> Create a custom `ExampleMatcher` that matches on ALL fields (use `matchingAny()` to match on *ANY* fields)
-<2> For the `name` field, use a wildcard that matches against the end of the field
-<3> Match columns against `null` (don't forget that `NULL` doesn't equal `NULL` in relational databases).
-<4> Ignore the `role` field when forming the query.
-<5> Plug the custom `ExampleMatcher` into the probe.
-
-It's also possible to apply a `withTransform()` against any property, allowing you to transform a property before forming the query.
-For example, you can apply a `toUpperCase()` to a `String` -based property before the query is created.
-
-Query By Example really shines when you don't know all the fields needed in a query in advance.
-If you were building a filter on a web page where the user can pick the fields, Query By Example is a great way to flexibly capture that into an efficient query.

-=== ID Generation
-
-Spring Data R2DBC uses the ID to identify entities.
-The ID of an entity must be annotated with Spring Data's https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
-
-When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
-
-Spring Data R2DBC does not attempt to insert values of identifier columns when the entity is new and the identifier value defaults to its initial value.
-That is `0` for primitive types and `null` if the identifier property uses a numeric wrapper type such as `Long`.
-
-One important constraint is that, after saving an entity, the entity must not be new anymore.
-Note that whether an entity is new is part of the entity's state.
-With auto-increment columns, this happens automatically, because the ID gets set by Spring Data with the value from the ID column.
-
-[[r2dbc.optimistic-locking]]
-=== Optimistic Locking
-
-The `@Version` annotation provides syntax similar to that of JPA in the context of R2DBC and makes sure updates are only applied to rows with a matching version.
-Therefore, the actual value of the version property is added to the update query in such a way that the update does not have any effect if another operation altered the row in the meantime.
-In that case, an `OptimisticLockingFailureException` is thrown.
-The following example shows these features:
-
-[source,java]
-----
-@Table
-class Person {
-
-  @Id Long id;
-  String firstname;
-  String lastname;
-  @Version Long version;

+== Naming Strategy
+
+By convention, Spring Data applies a `NamingStrategy` to determine table, column, and schema names defaulting to https://en.wikipedia.org/wiki/Snake_case[snake case].
+An object property named `firstName` becomes `first_name`.
+You can tweak that by providing a {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/NamingStrategy.html[`NamingStrategy`] in your application context.

+== Override table names
+
+When the table naming strategy does not match your database table names, you can override the table name with the {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/Table.html[`@Table`] annotation.
+The element `value` of this annotation provides the custom table name.
+The following example maps the `MyEntity` class to the `CUSTOM_TABLE_NAME` table in the database:
+
+[source,java]
+----
+@Table("CUSTOM_TABLE_NAME")
+class MyEntity {
+    @Id
+    Integer id;
+
+    String name;

+== Override column names
+
+When the column naming strategy does not match your database table names, you can override the table name with the {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/Column.html[`@Column`] annotation.
+The element `value` of this annotation provides the custom column name.
+The following example maps the `name` property of the `MyEntity` class to the `CUSTOM_COLUMN_NAME` column in the database:
+
+[source,java]
+----
+class MyEntity {
+    @Id
+    Integer id;
+
+    @Column("CUSTOM_COLUMN_NAME")
+    String name;
+}
+----
+
+ifdef::mapped-collection[]
+
+The {spring-data-jdbc-javadoc}org/springframework/data/relational/core/mapping/MappedCollection.html[`@MappedCollection`]
+annotation can be used on a reference type (one-to-one relationship) or on Sets, Lists, and Maps (one-to-many relationship).
+`idColumn` element of the annotation provides a custom name for the foreign key column referencing the id column in the other table.
+In the following example the corresponding table for the `MySubEntity` class has a `NAME` column, and the `CUSTOM_MY_ENTITY_ID_COLUMN_NAME` column of the `MyEntity` id for relationship reasons:
+
+[source,java]
+----
+class MyEntity {
+    @Id

+}

+
+[[entity-persistence.embedded-entities]]
+== Embedded entities
+
+Embedded entities are used to have value objects in your java data model, even if there is only one table in your database.
+In the following example you see, that `MyEntity` is mapped with the `@Embedded` annotation.
+The consequence of this is, that in the database a table `my_entity` with the two columns `id` and `name` (from the `EmbeddedEntity` class) is expected.
+
+However, if the `name` column is actually `null` within the result set, the entire property `embeddedEntity` will be set to null according to the `onEmpty` of `@Embedded`, which ``null``s objects when all nested properties are `null`. +
+Opposite to this behavior `USE_EMPTY` tries to create a new instance using either a default constructor or one that accepts nullable parameter values from the result set.
+
+.Sample Code of embedding objects
+====
+[source,java]
+----
+class MyEntity {
+
+    @Id
+    Integer id;
+
+    @Embedded(onEmpty = USE_NULL) <1>
+    EmbeddedEntity embeddedEntity;
+}
+
+class EmbeddedEntity {
+    String name;
+}
+----
+
+<1> ``Null``s `embeddedEntity` if `name` in `null`.
+Use `USE_EMPTY` to instantiate `embeddedEntity` with a potential `null` value for the `name` property.
+====
+
+If you need a value object multiple times in an entity, this can be achieved with the optional `prefix` element of the `@Embedded` annotation.
+This element represents a prefix and is prepend for each column name in the embedded object.
+
+[TIP]
+====
+Make use of the shortcuts `@Embedded.Nullable` & `@Embedded.Empty` for `@Embedded(onEmpty = USE_NULL)` and `@Embedded(onEmpty = USE_EMPTY)` to reduce verbosity and simultaneously set JSR-305 `@javax.annotation.Nonnull` accordingly.
+
+[source,java]
+----
+class MyEntity {
+
+    @Id
+    Integer id;
+
+    @Embedded.Nullable <1>
+    EmbeddedEntity embeddedEntity;
+}
+----
+
+<1> Shortcut for `@Embedded(onEmpty = USE_NULL)`.
+====
+
+Embedded entities containing a `Collection` or a `Map` will always be considered non-empty since they will at least contain the empty collection or map.
+Such an entity will therefore never be `null` even when using @Embedded(onEmpty = USE_NULL).

+If the annotated attribute is an entity or collection of entities, it is represented by one or more separate rows in separate tables.

Subject: [PATCH 1798/2145] Polishing.

Push JDBC-specific simple types into JdbcPostgresDialect instead of having these in the top-level dialect that shouldn't be tied to any driver technology.

Introduce profile to run Postgres tests only.

Subject: [PATCH 1801/2145] Fix test setup for Single Query Loading.

The construction of the DataAccessStrategy happened before the MappingContext was properly setup.
This is now fixed.
A test utilizes Single Query Loading, if it activates the profile singleQueryLoading

Subject: [PATCH 1802/2145] Introduce `MappingRelationalConverter`.

Add sophisticated converter to read aggregates from a RowDocument including support for maps, collections, subdocuments, and embeddables considering registered converters.
Use ResultSetRowDocumentExtractor to extract result multi-sets into RowDocument and then later apply object mapping.

Closes #1586

Subject: [PATCH 1813/2145] Fix `RowDocumentIterator.hasNext`.

This properly fixes the test setup, taking into account that @ActiveProfile by default replaces any profiles set via environment variable or system property.
It turns out that the hasNext calculation in RowDocumentIterator was wrong because

a) isBeforeFirst and isBeforeLast return both false when the ResultSet is empty.
b) isBeforeFirst and isBeforeLast aren't necessarily implemented for all ResultSets and for example DB2s ResultSet implementation don't support it by default.

Closes #1615

Subject: [PATCH 1815/2145] Refine JDBC integration tests.

Introduce composed annotations and conditions to deduplicate annotations required for a test, to express database runtime conditions and database activation.
Simplify test configuration.
Split tests into unit test and integration test run.

Original pull request #1621
Closes #1620

Subject: [PATCH 1823/2145] Polishing.

Remove Jetbrains annotation usage.

Simplify code, remove code that is commented out, extract methods, pass PersistentEntity as argument instead of creating instances that hold PersistentEntity as field to align the class lifecycle with its contextual usage.

Refactor AggregateReader lifecycle, use a single instance as there is no entity-specific state attached to AggregateReader.

Add Javadoc.

Subject: [PATCH 1824/2145] Remove excludes for maven test execution.

Maven Surefire and Failsafe plugins by default do not run inner classes, no matter if they are `@Nested` or just plain static inner classes.

This change removes this default exclude.

Closes #1627
See https://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#excludes

Subject: [PATCH 1832/2145] Replace `BatchJdbcOperations` with Spring's
 `NamedParameterJdbcOperations`.

BatchJdbcOperations is still there, but deprecated, and not used except for deprecated places kept for backward compatibility.

This is possible since Spring Framework made the features offered by `BatchJdbcOperations` part of `NamedParameterJdbcOperations`.

Closes #1616

Subject: [PATCH 1834/2145] Add failsafe:verify goal as an execution.

The failsafe plugin only fails during it's verify goal, not when actually executing the tests.

The goal is by default added to the verify phase.
But for the database tests this adds it to the integration-test phase.
This ensures that the build fail as soon a test for one database fails.

Closes #1637

Subject: [PATCH 1838/2145] Add support for multi-level projections using
 EntityProjection.

We now support multi-level projections by introspecting the result and the domain type and read projections directly into a DTO or a backing map for interface projections.

Subject: [PATCH 1851/2145] Connect build to ge.spring.io.

This change publishes a build scan to ge.spring.io for every local build from an authenticated Spring committer and for CI where appropriate access tokens are available. The build will not fail if publishing fails.

This change also allows the build to benefit from local and remote build caching, providing faster builds for all contributors.

Additionally, the project will have access to all features of Gradle Enterprise such as:

- Dashboards to view all historical build scans, along with performance trends over time
- Build failure analytics for enhanced investigation and diagnosis of build failures
- Test failure analytics to better understand trends and causes around slow, failing, and flaky tests

-=== Custom `RowMapper`
+=== Custom `RowMapper` or `ResultSetExtractor`
+
+The `@Query` annotation allows you to specify a custom `RowMapper` or `ResultSetExtractor` to use.
+The attributes `rowMapperClass` and `resultSetExtractorClass` allow you to specify classes to use, which will get instantiated using a default constructor.
+Alternatively you may set `rowMapperClassRef` or `resultSetExtractorClassRef` to a bean name from your Spring application context.
 
-You can configure which `RowMapper` to use, either by using the `@Query(rowMapperClass = ....)` or by registering a `RowMapperMap` bean and registering a `RowMapper` per method return type.
+If you want to use a certain `RowMapper` not just for a single method but for all methods with custom queries returning a certain type,
+you may register a `RowMapperMap` bean and registering a `RowMapper` per method return type.
 The following example shows how to register `DefaultQueryMappingConfiguration`:

Subject: [PATCH 1866/2145] Improve count and exists query projections.

We now use COUNT(*) and SELECT 1 for count respective exists queries to enable database optimizers instead of using the key columns.

Closes #1647

Since a PersistencePropertyPath does NOT consider it's owner for equality, this is necessary.
to distinguish different AggregatePath instances based on a inherited property.

Subject: [PATCH 1898/2145] Fix interface projection for entities that
 implement the interface.

Using as with an interface that is implemented by the entity, we no longer attempt to instantiate the interface bur use the entity type instead.

Subject: [PATCH 1909/2145] Consider registered converters using Row and
 RowDocument as source.

We now consider converters for RowDocument. Additionally, we reinstated conversion from R2DBC's Row type into entities as that converter functionality got lost during the converter revision.

Subject: [PATCH 1943/2145] Fix loading of 2nd level collections.

Construction of the back reference assumed that the table holding the parent of the foreign key is the actual parent property.
This is now corrected by using the correct API to identify the ancestor which holds the id.

Closes: #1692

Subject: [PATCH 1944/2145] Fix access of root property instead of child
 property.

When the child of a one-to-one relationship has an id, the value for that id gets read in the wrong way.
We get the column name for that id use that to access the value in the RowDocument.

This results in either no value at all being found or even worse, the value of a root entity with a property of same name being accessed.

This is fixed by using the full AggregatePath instead of just the property for accessing that value.

Closes #1684

Subject: [PATCH 1945/2145] Performance improvements.

Introduce caching for configured RowMapper/ResultSetExtractor.

We now create RowMapper/ResultSetExtractor instances only once if they are considered static configuration.
A configured RowMapper ref/class is always static.
A configured ResultSetExtractor ref/class is static when the extractor does not accept a RowMapper or if the RowMapper is configured.

Default mappers or projection-specific ones require ResultSetExtractor recreation of the ResultSetExtractor is configured as Class.

Reuse TypeInformation as much as possible to avoid Class -> TypeInformation conversion.
Introduce LRU cache for DefaultAggregatePath to avoid PersistentPropertyPath lookups.
Introduce best-effort quoted cache for SqlIdentifier to avoid excessive string object creation.

Subject: [PATCH 1952/2145] Reuse custom converters from
 `AggregateReferenceConverters`.

Let the AggregateReference converters now receive also custom converters as delegates.
Remove the ArrayToObjectConverter which just uses the first element of the array from the DefaultConversion service.

This does NOT solve the underlying problem, of having two DefaultConversionServices at work.
One is in the store conversion, one constructed in the AbstractRelationalConverter.
Although it looks like they get merged, the former contains converters, using that ConversionService as a delegate.

Attempts were made to move AggregateReferenceConverters out of the store converters and just register them directly,
but then no custom read/write targets are detected, leading to failed conversions.
The same problem prevents a registration in CustomConversions as a Function<ConversionService, GenericConverter> or similar, which would allow late registration.
The problem here is that custom read/write targets require the function to get evaluated, before custom read/write targets can be determined.

Closes #1750

Subject: [PATCH 1964/2145] Fix usage of wrong id value in related selects.

In an aggregate A->B-Collection<C> a select gets executed for loading Collection<C>.
That select used the wrong ID when B had an ID with the same name as A.

This is now fixed.

Subject: [PATCH 1969/2145] Create one connection pool for Oracle.

We now use one pooled `DataSource` for Oracle.

This should avoid problems with the TNS-Listener, which seems to have a problem with constantly opening and closing connections.

Closes #1815

Subject: [PATCH 1972/2145] Fix Auditing for embedded fields.

The reason for auditing to not work on embedded fields is that EmbeddedRelationalPersistentProperty and BasicRelationalPersisntentProperty were not considered equal even when they represent the same field.

Note: the fix is somewhat hackish since it breaks the equals contract for EmbeddedRelationalPersistentProperty.

Closes #1694
See https://github.com/spring-projects/spring-data-mongodb/commit/1545e184ef581d39fc538f582bae93fedde2aadf

Subject: [PATCH 1976/2145] Avoid double-conversion of values considered
 simple.

MappingJdbcConverter previously tried to create a JdbcValue for simple values via the ConversionService, only to drop the conversion result if the conversino did not result in a JdbcValue eventually. In that case it triggered an additional (same) conversion to then handle the wrapping of the conversion result into a JdbcValue manually.

This commit alters the flow so that it only triggers the conversion once and manually applies the JdbcValue wrapping only if the result of the original conversion is not a JdbcValue, yet.

Subject: [PATCH 1982/2145] Run test only on HsqlDb.

JdbcRepositoryEmbeddedIntegrationTests no longer runs for all databases, since it doesn't tests anything specific to differen RDBMSs.
Therefore the test also got renamed.

 The query is used for populating the aggregate root, embedded entities and one-to-one relationships including arrays of primitive types which get stored and loaded as SQL-array-types.
 Separate queries are generated for maps, lists, sets and arrays of entities.
 
+Properties one-to-one relationships must have there name prefixed by the name of the relationship plus `_`.
+For example if the `User` from the example above has an `address` with the property `city` the column for that `city` must be labeled `address_city`.

 WARNING: Note that String-based queries do not support pagination nor accept `Sort`, `PageRequest`, and `Limit` as a query parameter as for these queries the query would be required to be rewritten.
 If you want to apply limiting, please express this intent using SQL and bind the appropriate parameters to the query yourself.

+[[jdbc.template]]
+== Template API
+
+As an alternative to repositories Spring Data JDBC offers the javadoc:org.springframework.data.jdbc.core.JdbcAggregateTemplate[] as a more direct means to load and persist entities in a relational database.
+To a large extent, repositories use `JdbcAggregateTemplate` to implement their features.
+
+This section highlights only the most interesting parts of the `JdbcAggregateTemplate`.
+For a more complete overview, see the JavaDoc of `JdbcAggregateTemplate`.
+
+=== Accessing the JdbcAggregateTemplate
+
+`JdbcAggregateTemplate` is intended to be used as a Spring bean.
+If you have set up your application to include Spring Data JDBC, you can configure a dependency on `JdbcAggregateTemplate` in any Spring bean, and the Spring Framework injects a properly configured instance.
+
+This includes fragments you use to implement custom methods for your Spring Data Repositories, letting you to use `JdbcAggregateTemplate` to customize and extend your repositories.
+
+=== Persisting
+
+`JdbcAggregateTemplate offers three types of methods for persisting entities: `save`, `insert`, and `update`.
+Each comes in two flavors:
+Operating on single aggregates, named exactly as mentioned above, and with an `All` suffix operation on an `Iterable`.
+
+`save` does the same as the method of same name in a repository.
+
+`insert` and `update` skip the test if the entity is new and assume a new or existing aggregate as indicated by their name.
+
+=== Querying
+
+`JdbcAggregateTemplate` offers a considerable array of methods for querying aggregates and about collections of aggregates.
+There is one type of method that requires special attention.
+That's the methods taking a `Query` as an argument.
+They allow the execution of programmatically constructed queries, as follows:
+
+[source,java]
+----
+template.findOne(query(where("name").is("Gandalf")), Person.class);
+----
+
+The javadoc:org.springframework.data.relational.core.query.Query[] returned by the `query` method defines the list of columns to select, a where clause (through a CriteriaDefinition), and specification of limit and offset clauses.
+For details of the `Query` class, see its JavaDoc.
+
+The javadoc:org.springframework.data.relational.core.query.Criteria[] class, of which `where` is a static member, provides implementations of org.springframework.data.relational.core.query.CriteriaDefinition[], which represent the where-clause of the query.

Subject: [PATCH 2004/2145] Refactor code with instanceof pattern variable.

In some cases, we currently use the traditional `instanceof` checks followed by explicit type casting.
With the introduction of pattern matching in recent Java versions, we can refactor these checks to make the code more concise and readable.

Subject: [PATCH 2008/2145] Support for table names in SpEL expressions.

SpEL expressions in queries get processed in two steps:

1. First SpEL expressions outside parameters are detected and processed.
This is done with a `StandardEvaluationContext` with the variables `tableName` and `qualifiedTableName` added.
This step is introduced by this commit.

2. Parameters made up by SpEL expressions are processed as usual.

Closes #1856

Subject: [PATCH 2044/2145] Do not convert binary data in `List<byte[]>` to
 array SQL type.

byte[] is mapped to BINARY data and is not considered tuple data.

The explicit check for byte[] is not very nice but matches the special handling in MappingJdbcConverter.writeJdbcValue

Closes #1900

Subject: [PATCH 2058/2145] Fix id setting for partial updates of collections
 of immutable types.

We gather immutable entities of which the id has changed, in order to set them as values in the parent entity.
We now also gather unchanged entities.
So they get set with the changed one in the parent.

Subject: [PATCH 2082/2145] Polishing.

Fix merge problems.

Execute tests only for HsqlDb.

Refactoring to use lists instead of streams.
We try to avoid the latter, since they are prone to cause performance issues.

Minor refactorings.

Subject: [PATCH 2096/2145] Polishing.

Reference issues in tests comments.
Removed `DisabledOnDatabase`
IdGeneration default methods related to sequence generation are now internally consistent.
Formatting and naming.
IdGeneration offers simple support by default.
Fix exception in oracle integration test setup
Use SqlIdentifier for sequence names
Remove SEQUENCE id source
Added documentation

See #1923

 When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
 
-Spring Data does not attempt to insert values of identifier columns when the entity is new and the identifier value defaults to its initial value.
+If you annotate the id additionally with `@Sequence` a database sequence will be used to obtain values for the id.
+
+Otherwise Spring Data does not attempt to insert values of identifier columns when the entity is new and the identifier value defaults to its initial value.
 That is `0` for primitive types and `null` if the identifier property uses a numeric wrapper type such as `Long`.
 
 xref:repositories/core-concepts.adoc#is-new-state-detection[Entity State Detection] explains in detail the strategies to detect whether an entity is new or whether it is expected to exist in your database.

From d0e43be314e70416c52c288cc83c8eea8d4f401b Mon Sep 17 00:00:00 2001
From: Mark Paluch <mark.paluch@broadcom.com>
Date: Wed, 9 Apr 2025 10:00:31 +0200
Subject: [PATCH 2119/2145] Polishing.

Refine assignment flow and use early returns where possible. Cache empty MapSqlParameterSource. Reduce dependency on RelationalMappingContext using a lower-level abstraction signature. Simplify names. Use default value check from Commons. Fix log warning message. Add missing since tags.

Remove superfluous annotations and redundant code. Tweak documentation wording.

Closes #2003
Original pull request: #2005

 == ID Generation
 
-Spring Data uses the identifer property to identify entities.
+Spring Data uses identifier properties to identify entities.
+That is, looking these up or creating statements targeting a particular row.
 The ID of an entity must be annotated with Spring Data's https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/annotation/Id.html[`@Id`] annotation.
 
 When your database has an auto-increment column for the ID column, the generated value gets set in the entity after inserting it into the database.
 
-If you annotate the id additionally with `@Sequence` a database sequence will be used to obtain values for the id.
+If you annotate the identifier property additionally with `@Sequence` a database sequence will be used to obtain values for the id if the underlying `Dialect` supports sequences.
 
-Otherwise Spring Data does not attempt to insert values of identifier columns when the entity is new and the identifier value defaults to its initial value.
+Otherwise, Spring Data does not attempt to insert values of identifier columns when the entity is new and the identifier value defaults to its initial value.
 That is `0` for primitive types and `null` if the identifier property uses a numeric wrapper type such as `Long`.
 
 xref:repositories/core-concepts.adoc#is-new-state-detection[Entity State Detection] explains in detail the strategies to detect whether an entity is new or whether it is expected to exist in your database.

Subject: [PATCH 2120/2145] Move Sequence to RelationalPersistentProperty.

Sequence details are now maintained on the property level instead of using the entity level. This is a more accurate representation of the underlying model and that properties are annotated and not entities. It also allows future extension of expanding sequence support to general properties.

Extract delegate for sequence generation. Move types to org.springframework.data.jdbc.core.convert to resolve package cycles.

+= Sequences Support
+
+Since Spring Data R2DBC 3.5, properties that are annotated with `@Id` and thus represent
+an Id property can additionally be annotated with `@Sequence`. This signals, that the Id property
+value would be fetched from the configured sequence during an `INSERT` statement. By default,
+without `@Sequence`, the identity column is assumed. Consider the following entity.
+
+.Entity with Id generation from sequence
+[source,java]
+----
+@Table
+class MyEntity {
+
+    @Id
+    @Sequence(
+        sequence = "my_seq",
+        schema = "public"
+    )
+    private Long id;
+
+    private String name;
+}
+----
+
+When persisting this entity, before the SQL `INSERT` Spring Data will issue an additional `SELECT`
+statement to fetch the next value from the sequence. For instance, for PostgreSQL the query, issued by
+Spring Data, would look like this:
+
+.Select for next sequence value in PostgreSQL
+[source,sql]
+----
+SELECT nextval('public.my_seq');
+----
+
+The fetched Id would later be included in the `VALUES` list during an insert:
+
+.Insert statement enriched with Id value
+[source,sql]
+----
+INSERT INTO "my_entity"("id", "name") VALUES(?, ?);
+----
+
+For now, the sequence support is provided for almost every dialect supported by Spring Data R2DBC.
+The only exception is MySQL, since MySQL does not have sequences as such.
+

Subject: [PATCH 2131/2145] Polishing.

Extract SequenceEntityCallbackDelegate from IdGeneratingBeforeSaveCallback. Renameto IdGeneratingEntityCallback and move callback to convert package.

Align return values and associate generated sequence value with the entity. Fix test. Add ticket references to tests.

Extract documentation partials.

See #1955

-Since Spring Data R2DBC 3.5, properties that are annotated with `@Id` and thus represent
-an Id property can additionally be annotated with `@Sequence`. This signals, that the Id property
-value would be fetched from the configured sequence during an `INSERT` statement. By default,
-without `@Sequence`, the identity column is assumed. Consider the following entity.
-
-.Entity with Id generation from sequence
-[source,java]
-----
-@Table
-class MyEntity {
-
-    @Id
-    @Sequence(
-        sequence = "my_seq",
-        schema = "public"
-    )
-    private Long id;
-
-    private String name;
-}
-----
-
-When persisting this entity, before the SQL `INSERT` Spring Data will issue an additional `SELECT`
-statement to fetch the next value from the sequence. For instance, for PostgreSQL the query, issued by
-Spring Data, would look like this:
-
-.Select for next sequence value in PostgreSQL
-[source,sql]
-----
-SELECT nextval('public.my_seq');
-----
-
-The fetched Id would later be included in the `VALUES` list during an insert:
-
-.Insert statement enriched with Id value
-[source,sql]
-----
-INSERT INTO "my_entity"("id", "name") VALUES(?, ?);
-----
-
-For now, the sequence support is provided for almost every dialect supported by Spring Data R2DBC.
-The only exception is MySQL, since MySQL does not have sequences as such.

+Primary key properties (annotated with `@Id`) may also be annotated with `@Sequence`.
+The presence of the `@Sequence` annotation indicates that the property's initial value should be obtained from a database sequence at the time of object insertion.
+The ability of the database to generate a sequence is <<sequences.dialects,determined by the used database dialect>>.
+In the absence of the `@Sequence` annotation, it is assumed that the value for the corresponding column is automatically generated by the database upon row insertion.

Subject: [PATCH 2138/2145] Polishing.

Deprecate original DialectResolver and JdbcArrayColumns as they've been in the wrong package and introduce replacements in the dialect package. Let deprecated types extend from their replacements to retain compatibility.

Make instance holders final, fix Javadoc typos, update reference docs.

++ You can let Spring auto-discover your javadoc:org.springframework.data.jdbc.core.dialect.JdbcDialect[] by registering a class that implements `org.springframework.data.jdbc.core.dialect.DialectResolver$JdbcDialectProvider` through `META-INF/spring.factories`.
 `DialectResolver` discovers dialect provider implementations from the class path using Spring's `SpringFactoriesLoader`.
 To do so:
 
 . Implement your own `Dialect`.
 . Implement a `JdbcDialectProvider` returning the `Dialect`.
 . Register the provider by creating a `spring.factories`  resource under `META-INF` and perform the registration by adding a line +
-`org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider=<fully qualified name of your JdbcDialectProvider>`
+`org.springframework.data.jdbc.core.dialect.DialectResolver$JdbcDialectProvider`=<fully qualified name of your JdbcDialectProvider>`
