elasticsearch 6.x.x 獲取客戶端方法

創建Settings

Settings settings = Settings.builder().put("client.transport.ignore_cluster_name", true).build();//忽略集群名稱

創建客戶端

TransportClient transportClient = new PreBuiltTransportClient(settings);

獲取客戶端

Client client = transportClient.addTransportAddress(new TransportAddress(InetAddress.getByName(host), Integer.parseInt(port)));

// 創建客戶端

Settings settings = Settings.builder().put("cluster.name", "clustername").put("client.transport.sniff", true).build();//根據集群名稱創建setting

TransportClient client = new PreBuiltTransportClient(settings);
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("IP"), 9300));

以上為兩種獲取es不同setting的方式，指定集群名稱獲取集群，或者不指定集群名稱獲取集群。
