         client = getConnection();
      } catch (Exception e) {
         throw new RuntimeException("ES连接错误，请核对代码及配置！", e);
      }
   }

   @SuppressWarnings({"resource", "unchecked"})
   public static TransportClient getConnection() throws Exception {
      // 设置集群名称
      Settings settings = Settings.builder().put("cluster.name", "xxxx").build();
      // 创建client 配置IP和端口
      TransportClient client = new PreBuiltTransportClient(settings)
             .addTransportAddresses(new TransportAddress(InetAddress.getByName("xxxxxxx"),
             10902));
      return client;
   }
