如何重新打开套接字连接？

如何重新打开客户端的套接字连接，如果服务器已停止然后再次运行？

P.S。可能没必要看全部代码，看一遍Client代码中的"wait"循环

Socket socket = new Socket(ipAddress, serverPort);

while (true) 
{
    line = keyboard.readLine();
    try 
    {
       out.writeUTF(line);
       out.flush();
       line = in.readUTF();
    } 
    catch (SocketException e) 
    {
       while (socket.isClosed()) 
       {
           System.out.println("no signal");
           try 
           {
                Thread.sleep(200);
           }
           catch (InterruptedException e1) 
           {
                e1.printStackTrace();
           }

           //Here I need some code for reconnection
         }

    }
    System.out.println(line);
}

如果套接字关闭连接，客户端应该在 read/write 操作中得到异常。如果客户端想要重新建立连接，只需实现它。您的 catch 块应该完全按照您在代码片段开头所做的那样创建新套接字。

类似于以下内容：

while(true) {
    Socket socket = new Socket(ipAddress, serverPort);
    try {
        while(true) {
           // read/write operations
        }
    } catch (SocketException e) {
       continue; // this will return you to creation of new socket
    }
}
