保持（单线程）服务器套接字在意外的套接字关闭时监听客户端 [英] Keeping a (single threaded) server socket listening for clients on unexpected socket closure

问题描述

如何处理客户意外断开连接。我想保持服务器运行/监听，除非客户明确说明关闭。

How should one deal with clients disconnecting unexpectedly. I want to keep the server running/listening unless explicitly stated to close by the client.

例如，我的服务器正在侦听，然后关闭客户端导致服务器的方法结束 - 如何让它返回到方法的开头它是？

For example, my server is listening and then the client is closed which causes the server's method to end - how can I get it to return to the beginning of the method as it were?

    serverSocket = new ServerSocket(port);
    clientSocket = serverSocket.accept();         
    out = new PrintWriter(clientSocket.getOutputStream(), true);
    in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));                   
    BasicProtocol bp = new BasicProtocol(password);
    out.println(bp.processInput(""));
    String inputLine;
    while((inputLine = in.readLine()) != null ){
       System.out.println("Client asks: " + inputLine);
       out.println(bp.processInput(inputLine));            
    }

如上所述，如果发生连接重置错误，它怎么能等待重新连接to？

As above, if a connection reset error occurs how can it wait to be reconnected to?

推荐答案

例如，你可以在方法中使用一个boolean变量的while循环，当客户想要更改时关。因此：

For instance you can have a while loop at the method with a boolean variable that is changed when the client wants to close. As such:

boolean isRunning = true;
while (isRunning) {
    //Your current method - when client wants to disconnect just set isRunning = false;
}
