使用java客户端创建索引库

 //1、创建一个setting对象，相当于一个配置信息，主要配置集群的名称
 Settings settings = Settings.builder()
 .put("cluster.name", "my‐elasticsearch").build();
 //2、创建一个客户端client对象
 TransportClient client = new PreBuiltTransportClient(settings);
 client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),9301));
 client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),9302));
 client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),9303));
 //3、使用client对象，创建一个索引库
 client.admin().indices().prepareCreate("index_hello").get();
 //4、关闭client对象
 client.close();
