elasticsearch java無法連線、

Question

我在本地啟動的ES，使用CURL進行調用是沒問題的，但是在代碼中無法連接。

 Settings settings = Settings.builder().put("cluster.name", "cluster-tony").build();
        try {
            //创建client
            TransportClient client = new PreBuiltTransportClient(settings)
                    .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("192.168.0.230"), 9200));
            //搜索数据
            GetResponse response = client.prepareGet("blog", "article", "1").execute().actionGet();
            //输出结果
            System.out.println(response.getSourceAsString());
            //关闭client
            client.close();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }

在瀏覽器中訪問的結果：

{
  "name" : "7BaVGc5",
  "cluster_name" : "cluster-tony",
  "cluster_uuid" : "ctTbTQfvTUyzV00JMWPfyA",
