使用java客户端更新文档

package com.es.demo;

import java.net.InetAddress;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.ExecutionException;

import org.elasticsearch.action.get.GetResponse;
import org.elasticsearch.action.index.IndexRequest;
import org.elasticsearch.action.update.UpdateRequest;
import org.elasticsearch.action.update.UpdateResponse;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.index.get.GetResult;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import com.fasterxml.jackson.databind.ObjectMapper;

public class TestES3 {
	private static final String HOST = "127.0.0.1";
	private static final int PORT = 9300;
	
	private static final ObjectMapper MAPPER = new ObjectMapper();
	private TransportClient client = null;
	
	// 跟下文档
	@Test
	public void updateDocument() throws InterruptedException, ExecutionException{
		UpdateRequest request = new UpdateRequest("eshop", "product", "AWFlwM2XrUhLs_HfwSw1");
		Map<String, Object> source = new HashMap<String,Object>();
		source.put("name", "APPLE手机2");
		source.put("price", 10999);
		request.doc(source);
		
		UpdateResponse response = this.client.update(request ).get();
		System.out.println(response.getVersion());
	}
	
	// 获取客户端
	@Before
	public void getClient() throws Exception{
		client = TransportClient.builder()
		.build()
		.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(HOST), PORT));
	}
	
	// 关闭客户端
	@After
	public void closeClient(){
		if (this.client != null){
			this.client.close();
		}
	}
}
