HttpClient 4.3 设置keeplive 和 timeout 的方法

ConnectionKeepAliveStrategy kaStrategy = new DefaultConnectionKeepAliveStrategy() {
			@Override
			public long getKeepAliveDuration(HttpResponse response, HttpContext context) {
				long keepAlive = super.getKeepAliveDuration(response, context);
				if (keepAlive == -1) {
					//如果服务器没有设置keep-alive这个参数，我们就把它设置成1分钟
					keepAlive = 60000;
				}
				return keepAlive;
			}

		};

		CloseableHttpClient httpClient = HttpClients.custom().setKeepAliveStrategy(kaStrategy).build();

		HttpGet httpGet = new HttpGet(url);

		// 设置请求的超时时间
		RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(10000).setConnectTimeout(10000).build();
		httpGet.setConfig(requestConfig);

		CloseableHttpResponse response = null;

		response = httpClient.execute(httpGet);
