如何在多线程客户端/服务器应用程序中停止服务器？

Question

How do I get out of the while-loop?

Variable "running" is set TRUE by default and by receiving "shutdown" the value should be changed to FALSE and exit the Thread (the run-method). So the server gets closed after the while-loop.

ExecutorService executor = Executors.newFixedThreadPool(3);
        while (running) {
            Socket socket = server.accept();
            executor.execute(new Handler(socket,server));
        }
        executor.shutdown();
        server.close();

The run-method:

while(Server.getRunning()){
            System.out.println("..Wait for Input!");

            String inline = input.readLine();
            String[] a = inline.split(" ");

            int result;

            if (a[0].equals("shutdown")){
                Server.setRunning(false);
                Protocol.status(client, "shutdown");
                return;
            } 
}

I would suggest you wrap your loop in try-catch for SocketException and implement something like this:

public synchronized void shutdown()
{
   this.running = false;
   this.server.close();
}
