Question

   Settings settings = Settings.builder()
            .put("client.transport.ignore_cluster_name", false)
            .put("client.transport.sniff", true)
            .put("cluster.name", "TESTCULSTER").build();

    TransportClient client = new PreBuiltTransportClient(settings)
            .addTransportAddress(new TransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

  //  ClusterAdminClient clusterAdminClient = client.admin().cluster();


    ClusterHealthResponse healths = client.admin().cluster().prepareHealth().get();
    String clusterName = healths.getClusterName();
    System.out.println(clusterName);

我在纠错这个错误线程“main”中的异常NoNodeAvailableException [没有配置的节点可用：[{＃transport＃-1} {zJ52yLDcR82UUQ7j-oxm6w} {127.0.0.1} {127.0.0.1：9300}]]

您想通过Java连接到elasticsearch，对吧？

我建议使用HTTP传输（端口9200）而不是9300
您启用了“嗅探”，这意味着Java客户端将尝试直接连接到每个节点，确保可以进行通信
确保您可以从运行Java客户端的位置curl select TO_CHAR(Table1), Column1, column2 from a where Table1 between to_date(:beg_awd_date,'DD-MON-YYYY') AND to_date(:end_awd_date,'DD-MON-YYYY') order by column1
