Demonstrates a simple RESTful web service using Spring Boot and Java.This web service provides an in-memory UserRecord service, with the capability to get a all User information in the System, create user info,update user info, delete user info,user can be singIn in system,and logIn in system. After exploring this project, We will understand the three common layers of a RESTful web service (namely domain, data source, and presentation), the common design decisions used when creating a web service, and the functionality provided by the Spring framework for creating a web service (as well as supplemental functionality, such as creating HATEOAS links). In particular,We can aslo create OpenAPI Documantion with Swagger links).And expose the following API Endpoints.
- We can create a domain model with the help of lombok this easy beacuse we can reduce the boilerplate code.
- We can store domain objects in a persistence layer with the help of JPA
- We can wrap domain objects within resource objects.
- We can add HATEOAS links) links to a resource.Beacuse we can create self discoverable API.
- We can serve up resources to a client over HTTP
- We can provide RESTfull CreateUser,UpdateUser,DeleteUser,SearchUser,LoginUser,SingUpUser,AllUser this operations to change domain objects.
- We can create unit,integration with Individual Layer Controller,Service,Repository that exercise a REST API. this test create with the help of Mockito & Junit5.
- We can Document Your API Enpoint With Swagger.
- We can expose your API Endpoint with Swagger & Postman.
- We can Version Your API to maintain forward and backward compatibality Best practices for API versioning.
- We can determine your CodeCoverage.
- We can Configure your In-Memory Database apacheDerby.
- We can debug your In-Memory Database console.
- We can also understand slicing different components in UnitTest.
- We can also profiling & Seprate cross cutting concerns the whole project with the help pf AspectJ.
To start this web service,We can use SpringInitializr to build your all dependency in Maven Project.
Once the web service is started, it can be reached at
http://localhost:8080
