ES如何打印DSL

看了一下官网版本已经来到了8.17

正常打印似乎不行，突破的地方则是 藏在@JsonpDeserializable 这个注解上；

@JsonpDeserializable public class SearchRequest

因此只有反序列化出来之后才能打印，似乎就这么简单，看源码或许能更快的解决问题

方法一 查询打印 SearchRequest.Builder builder = new SearchRequest.Builder(); builder.query(q -> q.bool(boolQuery)); SearchRequest build = builder.build(); log.info("search request:【{}】", searchDSL(build)); public String searchDSL(SearchRequest searchRequest) { // 创建 JSON 生成器和 JSON 映射器 try (StringWriter writer = new StringWriter(); JsonGenerator generator = Json.createGenerator(writer) ) { JsonpMapper mapper = new JacksonJsonpMapper(); searchRequest.serialize(generator, mapper); generator.close(); return writer.toString(); } catch (Exception e) { log.error("search exception", e); } return null; }

打印es请求日志，在application.properties中添加 或者放到yaml 文件中

logging.level.org.elasticsearch.client.RestClient=DEBUG

方式二 AOP打印

使用aop对调用的方法进行处理；

import co.elastic.clients.elasticsearch.core.SearchRequest; import lombok.extern.slf4j.Slf4j; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Before; import org.aspectj.lang.annotation.Pointcut; import org.springframework.stereotype.Component; @Aspect @Component @Slf4j public class WebLogAspect { @Pointcut("execution(public * co.elastic.clients.elasticsearch.ElasticsearchClient.search(..))") public void before() { } @Before("before()") public void logRequest(JoinPoint joinPoint) { Object[] args = joinPoint.getArgs(); if (args.length > 0 && args[0] instanceof SearchRequest) { SearchRequest searchRequest = (SearchRequest) args[0]; log.info("请求参数: {}", searchRequest); } } }
