远程调用，限制请求超时时间处理

HttpClient处理 

HttpClient httpClientpost = new DefaultHttpClient();
String Posturl="xxx";
HttpPost httpPost = new HttpPost(Posturl); 

RequestConfig ReqConfig = 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(3 *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();

httpPost.setConfig(ReqConfig);
httpPost.setHeader("Content-Type", "application/json;charset=UTF-8");
httpPost.setEntity(new StringEntity(content, Charset.forName("utf-8")));
try { 
			HttpResponse postResponse = httpClientpost.execute(httpPost);
			HttpEntity entity = postResponse.getEntity();
			InputStream in = entity.getContent();
			ByteArrayOutputStream bos = new ByteArrayOutputStream();
			// 读取缓存
			byte[] buffer = new byte[2048];
			int length = 0;
			while ((length = in.read(buffer)) != -1) {
				// 写入输出流
				bos.write(buffer, 0, length);
			}
			// 读取完毕，关闭输入流
			in.close();
			jsonStr = new String(bos.toByteArray(), "UTF-8");
		} catch (ClientProtocolException e1) {
			String message = e1.getMessage();
			e1.printStackTrace();
		} catch (Exception e) {
			e.printStackTrace();
