卡住在java.net.SocketInputStream.socketRead0（本地方法）

我卡住在java.net.SocketInputStream.socketRead0（本地方法）。請參閱下面的線程轉儲，它已處於此狀態3小時。卡住在java.net.SocketInputStream.socketRead0（本地方法）

而且我已將連接超時和讀取超時設置爲URLConnection。請參閱下面的代碼片段。所以我不知道爲什麼它會掛在java.net.SocketInputStream.socketRead0。我偶爾會遇到這個問題。任何建議表示讚賞！

public String sendPost(String params) throws Throwable { 
PrintWriter out = null; 
String htmlContent = null; 
try 
{ 
    StringBuffer strBuffer = new StringBuffer(); 
    URL url = new URL(this.webUrl); 
    URLConnection urlConnection = url.openConnection(); 
    urlConnection.setConnectTimeout(3000); 
    urlConnection.setReadTimeout(3000); 

    urlConnection.setRequestProperty("accept", "*/*"); 
    urlConnection.setRequestProperty("connection", "Keep-Alive"); 
    urlConnection.setRequestProperty("user-agent", "***"); 

    urlConnection.setDoOutput(true); 
    urlConnection.setDoInput(true); 

    out = new PrintWriter(urlConnection.getOutputStream()); 
    out.print(params); 
    out.flush(); 

    BufferedReader bufferdReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream(), "utf-8")); 
    String readLine = null; 
     try { 
      while ((readLine = bufferdReader.readLine()) != null) { 
       strBuffer.append(readLine); 
      } 
     } catch (Throwable e) { 
      return htmlContent; 
     } 
     htmlContent = strBuffer.toString(); 
     bufferdReader.close();

'連接：保持alive'是默認的。你不寫任何POST參數：這是故意的嗎？ – EJP 2014-09-22 07:45:47

謝謝@EJP，我只是將更多的代碼粘貼到代碼引用中，這是一個後期操作。請再次查看.. – BurningDocker 2014-09-22 07:59:00

你有任何更新嗎？我有完全相同的問題 – HamoriZ 2014-11-20 14:18:42
