java - 套接字异常 : Connection reset after reconnect

Question

如果我先启动服务器，然后启动客户端，一切都会正常，但是当我先启动客户端，然后启动服务器时(确保客户端能够在 svr 崩溃时连接，然后再次上线)，客户端确实连接到服务器，但 2.3 秒后它抛出 SocketException:连接重置。我不知道是什么原因造成的，如果有人能帮助我解决这个问题，我将非常感激。

处理客户端的服务器代码:

public ServerHandler(Socket socket){
    try{
        pw = new PrintWriter(socket.getOutputStream());
        writerHolder[userCounter] = pw;

        InputStreamReader in = new          InputStreamReader(socket.getInputStream());
        reader = new BufferedReader(in);


        userCounter++;// Increment the number of people connected

    }catch(Exception ex)
    {
        ex.printStackTrace();
    }
}

连接到服务器的客户端代码:

    private  void startConnection()
{
    try
    {
        sock = new Socket("192.168.1.5", 5000);
        InputStreamReader input = new InputStreamReader(sock.getInputStream());
        reader = new BufferedReader(input);
        pw = new PrintWriter(sock.getOutputStream());
        JOptionPane.showMessageDialog(null, "Connected to the server!");

    }catch(IOException ex)
    {
        //timer.reconnectTimer(20);
        ex.printStackTrace();
    }
}

“连接重置”通常意味着远程端关闭了套接字的一侧，而没有读取您发送的数据。确保在关闭套接字之前读取发送给您的数据。
