使用java如何操作elasticsearch？简单示例。

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();
    }
}
