httpclient: 设置请求的超时时间，连接超时时间等

public static void main(String[] args) throws Exception{
		
		//创建httpclient
		CloseableHttpClient httpClient = HttpClients.createDefault();
		//创建http get
		HttpGet httpGet = new HttpGet("http://www.taotao.com/");
		//构建超时等配置信息
		RequestConfig config = RequestConfig.custom().setConnectTimeout(1000) //连接超时时间
				.setConnectionRequestTimeout(1000) //从连接池中取的连接的最长时间
				.setSocketTimeout(10 *1000) //数据传输的超时时间
				.setStaleConnectionCheckEnabled(true) //提交请求前测试连接是否可用
				.build();
		//设置请求配置时间
		httpGet.setConfig(config);
		
		//接受返回的数据
		CloseableHttpResponse response = null;
		
		try {
			response = httpClient.execute(httpGet);
		}finally{
			if(response!=null){
				response.close();
			}
			httpClient.close();
		}
