学习elasticsearch的时候，想要查看elasticsearch发送的DSL语句，类似MyBatis可以在idea的控制台上输出Mysql语句，可以添加如下配置

一、配置RestHighLevelClient

/**
 * @author wfd
 * @description
 * @create 2021/3/7 23:10
 */
@Configuration
public class EsConfig {

	// @Bean
	// public RestHighLevelClient restHighLevelClient() {
	// 	return new RestHighLevelClient(
	// 			RestClient.builder(
	// 					new HttpHost("192.168.126.130", 9200, "http")));
	// }
	
	// 将RestHighLevelClient 修改成这种方式
	@Bean(destroyMethod = "close")
	public RestHighLevelClient restClient() {

		ClientConfiguration clientConfiguration = ClientConfiguration.builder()
				.connectedTo("192.168.126.130:9200")
				.build();

		RestHighLevelClient client = RestClients.create(clientConfiguration).rest();
		return client;
	}
}

二、在application.yml添加日志输出

logging:
  level:
    org.springframework.data.elasticsearch.client.WIRE: TRACE

三、效果

注意：本文使用 Springboot 2.4.3,、RestHighLevelClient，elasticsearch使用的是 7.9.3
