Question

我在代码中添加了日志，只是为了理解其执行的顺序和时间，但到目前为止只是让人感到困惑！

当我执行此代码并启动服务器时，我得到了这些输出

＆＃34;启动服务器＆＃34;，＆＃34; ServerThread＆＃34;

＆＃34;倾听＆＃34;，＆＃34; ServerThread＆＃34;

＆＃34;连接到达＆＃34;，＆＃34; ServerThread＆＃34;

然后停在那里，当我连接到服务器时，我只得到

＆＃34;接受连接＆＃34;，＆＃34; ServerThread＆＃34;

好像它挂在

上

socket = serverSocket.accept();

它是否支持退出尝试以获得某种异常并再次打印整个内容？

class ServerThread implements Runnable {

    public void run() {
        Socket socket = null;
        try {
            Log.e("start server", "ServerThread");
            serverSocket = new ServerSocket(SERVERPORT);
        } catch (IOException e) {
            e.printStackTrace();
            Log.e("IO error at starting server", "ServerThread");
        } catch (Exception e) {
            Log.e("Exc at starting server", "ServerThread");
        }
        while (!Thread.currentThread().isInterrupted()) {
            Log.e("listening", "ServerThread");
            try {
                Log.e("connection arrived", "ServerThread");
                socket = serverSocket.accept();
                Log.e("connection accepted", "ServerThread");
                CommunicationThread commThread = new CommunicationThread(
                        socket);
                new Thread(commThread).start();

            } catch (IOException e) {
                e.printStackTrace();
                Log.e("IO error at accept", "ServerThread");
            } catch (Exception e) {
                Log.e("Exc at accept", "ServerThread");
            }
        }

    }
}

这是一种阻止方法，它将阻止，直到您收到连接。
