3.2_springBoot2.1.x检索之JestClient操作ElasticSearch

这里介绍Jest方式交互，

导入jest版本

<!--导入jest-->
        <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();
        }

    }
