@Override 
public void run() { 
    while (true) { 
     try { 
      URLConnection connection = getURLConnection("http://www.trekpv.com"); 
      BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream())); 
      String s; 
      while ((s = reader.readLine()) != null) { 
       System.out.println(s); 
      } 
      reader.close(); 
      Thread.sleep(5000); 
     } catch (Exception e) { 
      e.printStackTrace();

    urlconnection.setReadTimeout(10000); 
    urlconnection.addRequestProperty("Connection", "keep-alive");

'连接超时'表示根本没有响应。可能有防火墙的方式。

当指定的URL未在特定的持续时间内获取时，会发生SocketTimeoutException。这可能是因为互联网连接速度慢，或者代码中存在一些故障，导致无法获取url。
