ElasticsearchRestTemplate多数据源

ElasticsearchRestTemplate支持多数据源,可以通过以下步骤实现:
1. 配置多个ElasticsearchRestTemplate实例,每个实例对应一个数据源。
2. 创建多个ElasticsearchOperations实例,每个实例对应一个数据源,可以通过ElasticsearchRestTemplate的convert方法将ElasticsearchRestTemplate实例转换为ElasticsearchOperations实例。
3. 在需要访问不同数据源的方法中,使用对应的ElasticsearchOperations实例进行操作。
例如,以下代码展示了如何配置两个数据源,创建对应的ElasticsearchRestTemplate和ElasticsearchOperations实例,并在方法中使用不同的ElasticsearchOperations实例进行操作:
```
@Configuration
public class ElasticsearchConfig {
@Bean(name = "es1")
public ElasticsearchRestTemplate elasticsearchTemplate1() {
RestClientBuilder restClientBuilder = RestClient.builder(
new HttpHost("localhost", 9200, "http")
);
return new ElasticsearchRestTemplate(restClientBuilder);
}
@Bean(name = "es2")
public ElasticsearchRestTemplate elasticsearchTemplate2() {
RestClientBuilder restClientBuilder = RestClient.builder(
new HttpHost("localhost", 9201, "http")
);
return new ElasticsearchRestTemplate(restClientBuilder);
}
@Bean(name = "es1Operations")
public ElasticsearchOperations elasticsearchOperations1(@Qualifier("es1") ElasticsearchRestTemplate elasticsearchRestTemplate) {
return elasticsearchRestTemplate;
}
@Bean(name = "es2Operations")
public ElasticsearchOperations elasticsearchOperations2(@Qualifier("es2") ElasticsearchRestTemplate elasticsearchRestTemplate) {
return elasticsearchRestTemplate;
}
@Autowired
@Qualifier("es1Operations")
private ElasticsearchOperations es1Operations;
@Autowired
@Qualifier("es2Operations")
private ElasticsearchOperations es2Operations;
public void methodUsingEs1() {
// 使用es1Operations操作数据源1
}
public void methodUsingEs2() {
// 使用es2Operations操作数据源2
}
}
```
