Question

当我使用TransPortClient方法创建ElasticSearch客户端时。代码是这样的：

public static void main(String[] args) {

    // ES config
    Settings settings = settingsBuilder()
            .put("cluster.name", "dev-application")
            .put("client.transport.sniff", true)
            .build();
    // ES client
    try {
        TransportClient client = TransportClient.builder().settings(settings).build()
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));
    } catch (Exception e) {
        System.out.println("print");
        e.printStackTrace();
    }
    System.out.println("print");
}

但我收到错误信息显示如下：

01:32:09.288 [main] DEBUG org.elasticsearch.client.transport - [Magilla] node_sampler_interval[5s]

我无法理解这是怎么发生的，有人能遇见这个问题吗？感谢!!!

您似乎与来自两个不同JAR（JBoss和Jlasticsearch）的Netty类存在依赖冲突。

如果是这种情况，你需要排除JBoss，即org.jboss.nettypackage，你应该很好。

连接本地环境时，ElasticSearch无法获取TransPortClient
