依赖:<dependency><groupId>org.elasticsearch.client</groupId><artifactId>elasticsearch-rest-high-level-client</artifactId></dependency>修改版本: 第一步:条件准备:首先是配置类:@ConfigurationpublicclassEsConfig{

/***match_all查询所有*/@Testpublicvoidtest02()throwsIOException{SearchRequestsearchRequest=newSearchRequest("hotel");SearchSourceBuildersearchSourceBuilder=newSearchSourceBuilder();

/***rang范围查询*/@Testpublicvoidtest04()throwsIOException{SearchRequestsearchRequest=newSearchRequest();SearchSourceBuildersearchSourceBuilder=newSearchSourceBuilder();searchSourceBuilder

/***term精确查询*/@Testpublicvoidtest03()throwsIOException{SearchRequestsearchRequest=newSearchRequest();SearchSourceBuildersearchSourceBuilder=newSearchSourceBuilder();searchSourceBuilder.

查询文档的基本步骤1）准备Request对象2）准备请求参数3）发起请求4）解析响应示例解析以match_all查询为例代码解读：第一步，创建SearchRequest对象，指定索引库名第二步，利用request.source()构建DSL，DSL中可以包含查询、分页、排序、高亮等query()：代表查询条件，利用QueryBuilder

新增文档1）创建Request对象2）准备请求参数，也就是DSL中的JSON文档3）发送请求代码示例：点击查看代码//新增文档@TestpublicvoidaddDoc()throwsException{//根据id查出酒店数据Hotelhotel=iHotelService.getById(36934L);//将酒店
