Java Stop服务器线程

Question

以下代码是我的应用中的服务器代码：

private int serverPort;

private Thread serverThread = null;

public void networkListen(int port){

    serverPort = port;

    if (serverThread == null){
        Runnable serverRunnable = new ServerRunnable();
        serverThread = new Thread(serverRunnable);
        serverThread.start();
    } else {

    }
}

public class ServerRunnable implements Runnable {

    public void run(){

        try {

            //networkConnected = false;
            //netMessage = "Listening for Connection";
            //networkMessage = new NetworkMessage(networkConnected, netMessage);
            //setChanged();
            //notifyObservers(networkMessage);

            ServerSocket serverSocket = new ServerSocket(serverPort, backlog);

            commSocket = serverSocket.accept();

            serverSocket.close();
            serverSocket = null;

            //networkConnected = true;
            //netMessage = "Connected: " + commSocket.getInetAddress().getHostAddress() + ":" +
                    //commSocket.getPort();
            //networkMessage = new NetworkMessage(networkConnected, netMessage);
            //setChanged();
            //notifyObservers(networkMessage);

        } catch (IOException e){

            //networkConnected = false;
            //netMessage = "ServerRunnable Network Unavailable";
            //System.out.println(e.getMessage());
            //networkMessage = new NetworkMessage(networkConnected, netMessage);
            //setChanged();
            //notifyObservers(networkMessage);
        }
    }
}

代码工作方式，即如果我尝试直接连接，则两端进行通信和更新。

问题是即时通讯正在侦听连接，如果我想退出侦听，则服务器线程会继续运行并导致问题。

我知道我不应该在线程上使用.stop（），所以我想知道解决方案的外观如何？

编辑：注释掉不需要的代码。

从外部线程关闭服务器套接字。根据Serversocket.close（）上的文档，阻塞接受将抛出SocketException，您可以关闭线程。
