访问Elasticsearch集群方式

访问集群方式.png

使用TransportClient的代码示例：

try {
            int port = 9300;
            Map m = new HashMap();
            // 设置client.transport.sniff为true来使客户端去嗅探整个集群的状态，
           //把集群中其它机器的ip地址加到客户端中，这样本地节点挂了，程序还可以正常工作
            Settings settings = Settings.settingsBuilder().put(m).put("cluster.name", "elasticsearch").put("client.transport.sniff", true).build();
            client = TransportClient.builder().settings(settings).build();
            String ip = "";
            InetAddress host = InetAddress.getLocalHost();
            client.addTransportAddress(new InetSocketTransportAddress(host, port));
        } catch (Exception e) {
            e.printStackTrace();
        }
