java - ElasticSearch TransportClient 版本 5.6

Question

我是 Elastisearch Java API 新手

我安装了版本5.6，我的服务器elasticsearch正在运行

http://localhost:9200/

 {
      "name" : "KJj0iv3",
      "cluster_name" : "elasticsearch",
      "cluster_uuid" : "0je2mMloQ52X_GT1itxGuA",
      "version" : {
        "number" : "5.6.3",
        "build_hash" : "1a2f265",
        "build_date" : "2017-10-06T20:33:39.012Z",
        "build_snapshot" : false,
        "lucene_version" : "6.6.1"
      },
      "tagline" : "You Know, for Search"
    }

这是我的测试 Java 课

public static void main(String[] args) throws UnknownHostException {
    try {
        TransportClient client;

        client = new PreBuiltTransportClient(Settings.EMPTY)
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9200));
        // on shutdown
        client.close();
    } catch (ElasticsearchException e) {
        System.out.println(e.getMessage());
    }
}

这是我的错误

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.

Answer 1

在 9200 上使用端口 9300 代替 TransportClient需要端口 9300，因为它使用传输模块进行通信。
