请使用springboot写一个api返回查询ES数据源的索引,接口参数为ES数据源id和表名

以下是一个简单的实现:
1. 首先需要在pom.xml文件中添加elasticsearch的依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
```
2. 在application.properties中配置elasticsearch的连接信息:
```properties
spring.data.elasticsearch.cluster-nodes=localhost:9300
spring.data.elasticsearch.cluster-name=my-application
```
3. 创建一个Elasticsearch的Repository类:
```java
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
public interface ElasticsearchIndexRepository extends ElasticsearchRepository<Index, String> {
Index findByDataSourceIdAndTableName(String dataSourceId, String tableName);
}
```
4. 创建一个Controller类:
```java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class ElasticsearchIndexController {
@Autowired
private ElasticsearchIndexRepository elasticsearchIndexRepository;
@GetMapping("/indices/{dataSourceId}/{tableName}")
public Index getIndex(@PathVariable String dataSourceId, @PathVariable String tableName) {
return elasticsearchIndexRepository.findByDataSourceIdAndTableName(dataSourceId, tableName);
}
}
```
5. Index类需要实现序列化接口,并且需要定义@Document注解:
```java
import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
import java.io.Serializable;
@Document(indexName = "indices", type = "index")
public class Index implements Serializable {
@Id
private String id;
private String dataSourceId;
private String tableName;
// getters and setters
}
```
6. 运行项目,访问`http://localhost:8080/indices/{dataSourceId}/{tableName}`即可查询对应的索引信息。
