这里介绍Jest方式交互，

**导入jest版本**

<dependency>
                <groupId>io.searchbox</groupId>
                <artifactId>jest</artifactId>
                <version>6.3.1</version>
            </dependency>

**application.yml配置**

#配置jest
    spring:
      elasticsearch:
        jest:
          uris: http://Ip:9200

测试：

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class Springboot03ElasticsearchApplicationTests { 
        //自动注入jest
        @Autowired
        JestClient jestClient;
        
        
        //jest
        @Test
        public void contextLoads() { 
            //1、给Es中索引（保存）一个文档
            Article article = new Article();
            article.setId(1);
            article.setTitle("java入门到放弃");
            article.setAuthor("jiatp");
            article.setContent("测试内容");
    
            //2、构建一个索引功能 type(类型名字)
            Index build = new Index.Builder(article).index("jiatp").type("news").build();
            try { 
                //3、执行
                jestClient.execute(build);
            } catch(IOException e) { 
                e.printStackTrace();
            }
    
        }
    }
    
     //测试搜索
        @Test
        public void testSearch(){ 
    
            String json = "{\n" + " \"query\" : {\n" + " \"match\" : {\n"
                    + " \"content\" : \"测试内容\"\n" + " }\n"
                    + " }\n" + "}";
    
            //构建搜索
            Search search = new Search.Builder(json).addIndex("jiatp").addType("news").build();
            try { 
                SearchResult result = jestClient.execute(search);
                System.out.println(result.getJsonString());
            } catch(IOException e) { 
                e.printStackTrace();
            }
    
        }
