Java URL连接超时

Question

我正在尝试从 HTTP URL 解析 XML 文件。我想配置 15 秒的超时，如果 XML 提取时间比这更长，我想报告超时。由于某种原因，setConnectTimeout 和 setReadTimeout 不起作用。代码如下:

          URL url = new URL("http://www.myurl.com/sample.xml");
          URLConnection urlConn = url.openConnection();
          urlConn.setConnectTimeout(15000);
          urlConn.setReadTimeout(15000);
          urlConn.setAllowUserInteraction(false);         
          urlConn.setDoOutput(true);

          InputStream inStream = urlConn.getInputStream();
          InputSource input = new InputSource(inStream);

我正在捕获 SocketTimeoutException。

谢谢克里斯

试试这个:

       import java.net.HttpURLConnection;

       URL url = new URL("http://www.myurl.com/sample.xml");

       HttpURLConnection huc = (HttpURLConnection) url.openConnection();
       HttpURLConnection.setFollowRedirects(false);
       huc.setConnectTimeout(15 * 1000);
       huc.setRequestMethod("GET");
       huc.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");
       huc.connect();
       InputStream input = huc.getInputStream();

或

       import org.jsoup.nodes.Document;

       Document doc = null;
       try {
           doc = Jsoup.connect("http://www.myurl.com/sample.xml").get();
       } catch (Exception e) {
           //log error
       }
