XPackTransportClient

如果 ElasticSearch 服务安装了 x-pack 插件，需要PreBuiltXPackTransportClient实例才能访问

使用Maven管理项目，把下面代码增加到pom.xml;

一定要修改默认仓库地址为https://artifacts.elastic.co/maven ，因为这个库没有上传到Maven中央仓库

实例

Settings settings = Settings.builder().put("cluster.name", "xxx")
                    .put("xpack.security.transport.ssl.enabled", false)
                    .put("xpack.security.user", "xxx:xxx")
                    .put("client.transport.sniff", true).build();
try {
    client = new PreBuiltXPackTransportClient(settings)
            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("xxx.xxx.xxx.xxx"), 9300))
            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("xxx.xxx.xxx.xxx"), 9300));
} catch (UnknownHostException e) {
    e.printStackTrace();
}
