注意：

不同版本的ES API差别较大，引入jar包版本一定要和生产保持一致。工具类及使用方法可以参考备件系统项目：源码见GitHub

工具类及使用方法可以参考备件系统项目：源码见GitHub

 

引入jar包：

<dependency>

<groupId>org.elasticsearch</groupId>

<artifactId>elasticsearch</artifactId>

<version>2.4.0</version>

</dependency>

写测试类：

 

package com.sxt.es.test;import java.net.InetAddress;import java.util.Date;import org.elasticsearch.action.index.IndexResponse;import org.elasticsearch.client.transport.TransportClient;import org.elasticsearch.common.transport.InetSocketTransportAddress;import org.elasticsearch.common.xcontent.XContentFactory;public class Testes {        private static String host="192.168.136.131"; // 服务器地址    private static int port=9300; // 端口        public static void main(String[] args) throws Exception {                TransportClient client = TransportClient.builder().build()                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(Testes.host), Testes.port));        IndexResponse response =client.prepareIndex("twitter", "tweet", "1")                .setSource(XContentFactory.jsonBuilder()                        .startObject()                        .field("user", "kimchy")                        .field("postDate", new Date())                        .field("message", "trying out Elasticsearch")                    .endObject()                        )                .get();            System.out.println("索引名称："+response.getIndex());            System.out.println("类型："+response.getType());            System.out.println("文档ID："+response.getId()); // 第一次使用是1        client.close();    }}
