方式一：

这里使用基于其封装的高层API，即RestHighLevelClient

1、pom文件加入依赖包

　　　　  <!--        ES连接配置-->
        <!-- https://mvnrepository.com/artifact/org.elasticsearch.client/elasticsearch-rest-high-level-client -->
        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>6.8.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch -->
        <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>6.8.2</version>
        </dependency>

2、配置文件新增

es:
  url: xx.xx.xx.xx
  port: xxxx
  scheme: http

3、代码中引入

@Configuration
public class EsConfigConstant  {
    private static final Logger LOG = LoggerFactory.getLogger(EsConfigConstant.class);
    @Value("${es.url}")
    private String url;
    @Value("${es.port}")
    private Integer port;
    @Value("${es.scheme}")
    private String scheme;


   @Bean
    public RestHighLevelClient restHighLevelClient(){
        RestHighLevelClient restHighLevelClient = new RestHighLevelClient(
                RestClient.builder(new HttpHost(url,port,scheme))
        );
        return restHighLevelClient;
    }
}

4、代码中使用

    @Autowired
    private RestHighLevelClient restHighLevelClient;

5、可以进行余下操作了。。。
