<!-- add the shield jar as a dependency -->

<version>2.4.3</version>

注意：shield的maven依赖版本必须是2.4.3的，官方例子写的是2.2.0的无法正常运行。因为我们的shield安装的版本也是2.4.3、要保持版本一致。

Settings settings = Settings.settingsBuilder()
.put("cluster.name", "elasticsearch")
//设置shield创建的用户名和密码
.put("shield.user", "es_admin:123456")
.build();
TransportClient client = TransportClient.builder()
//添加shield plugin
.addPlugin(ShieldPlugin.class)
.settings(settings).build();
client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("192.168.80.100"), 9300));
