Question

我的代码就是这个

try
    {
        //Connect to the login server
        socket = new Socket(hostName , 15000);
        out = new ObjectOutputStream(socket.getOutputStream());
        input = new ObjectInputStream(socket.getInputStream());

                    .. //perform the login , if the login succeed make answ=1;
    }
    catch (UnknownHostException e) {
        System.err.println("Unknown host: " + hostName);
        StatusLabel.setText("Unknown host");
    }
    catch (ConnectException e) {
        System.err.println("Connection refused by host: " + hostName);
        StatusLabel.setText("Connection refused by host, server is down.");
    }
    catch (IOException e) {
        e.printStackTrace();
    }
    finally {
        try 
        {
            //Finaly closing the connection
            socket.close();
            System.out.flush();
            System.out.println("Socket Closed");
                            //closing the output and input stream
            out.close();
            input.close();
            setVisible(false); //closing the window
        }
        catch (IOException e ) {
            System.out.println("Couldn't close socket");
        }
    }
    if(answ==1) //if the login suceed start the class for the game
    {
        Gumoku_Graphics g = new Gumoku_Graphics();
        g.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        g.Play();
    }

在Gumoku_Graphics（）里面我调用这个与游戏服务器连接的类

Game n = new Game();
status=n.Connection();

是

 public int Connection()  
{
    try {
        socket = new Socket(hostName, 15432);
        System.out.println("socket ok\n");

        out = new ObjectOutputStream(socket.getOutputStream());
        System.out.println("out ok\n");


        input = new ObjectInputStream(socket.getInputStream());
        System.out.println("socket,out,input ok\n");
        return 1;
    }

    catch (UnknownHostException e) {
        System.err.println("Unknown host: " + hostName);
        return 0;
    }
    catch (ConnectException e) {
        System.err.println("Connection refused by host: " + hostName);
        return 0;
    }
    catch (IOException e) {
        e.printStackTrace();
        return 0;
    }
}

并且每次停在＆＃34; input = new ObjectInputStream（socket.getInputStream（））;＆＃34; 它不能这样做而且它会卡在那里。它打印＆＃34; socket ok＆＃34;，＆＃34; out ok＆＃34;它停留在那里。有什么问题？我做错了什么？

来自ObjectInputStream documentation：

创建一个从指定的InputStream读取的ObjectInputStream。从流中读取序列化流头并进行验证。此构造函数将阻塞，直到相应的ObjectOutputStream已写入并刷新标头。

如上所述，调用将阻塞，直到可以读取标头。在此调用可以继续之前，您需要从套接字到达一些数据。
