## 1、支持多数据源

数据源解析顺序:

- [ ] 对象@datasource

- [ ] 全局 @datasource

- [ ] 应用默认 @datasource

```json
{
// "@datasource": "db2" 全局
"@post": {
"User:aa": {
"@datasource": "db2" // 对象
},
"User_address[]": {
"@datasource": "db2"
}
},
"User:aa":{
"username":"test-3",
"password": "233223",
"state": 1
},
"ES_blog:a": {
"@datasource": "elasticSearch",
"title.keyword": "test-2"
},
"User_address[]": [
{
"user_id@": "User:aa/id",
"addr": "ddd",
"count@": "ES_blog:a/count"
},
{
"user_id@": "User:aa/id",
"addr": "ddd1",
"count@": "ES_blog:a/count"
}
],
"@explain": true
}
```

## 2、集成elasticsearch-sql

换成xpack, 也一样

应用导入: elasticsearch-sql-7.17.5.0.jar

## 3、apijson支持elasticsearch功能点

新增、修改、删除、查询

## 4、elasticsearch-sql不支持RLIKE

## 5、apijson支持字段 .keyword

```
{
"@datasource": "elasticSearch",
"ES_blog:aa":{
"title.keyword$": "%test-2",
"content": "u-c-2",
"url": "u-u-2",
"postdate": "2008-12-11",
"count": 1
},
"tag": "ES_blog",
"@explain": true
}
```



## 4、示例

### 单条插入

```
http://localhost:8080/post

{
"@datasource": "elasticSearch",
"ES_blog:aa":{
"title":"test-1",
"author": "a-1",
"content": "c-1",
"url": "u-1",
"postdate": "2018-12-11",
"count": 1
},
"tag": "ES_blog",
"@explain": true
}

```




elasticsearch查询插入的数据:

GET /es_blog/_doc/5b77b103-0231-42c3-a6cf-a0cb933d3dda


### 批量插入

```json
http://localhost:8080/post

{
"@datasource": "elasticSearch",
"ES_blog:aa[]": [
{
"title":"test-1",
"author": "a-1",
"content": "c-1",
"url": "u-1",
"postdate": "2018-12-11",
"count": 1
},
{
"title":"test-2",
"author": "a-2",
"content": "c-2",
"url": "u-2",
"postdate": "2018-12-11",
"count": 2
},
{
"title":"test-3",
"author": "a-3",
"content": "c-3",
"url": "u-3",
"postdate": "2018-12-11",
"count": 3
}
],
"tag": "ES_blog[]",
"@explain": true
}

```

elasticsearch查询插入的数据:

GET /es_blog/_search
