好的,所以我有这个扩展 JFrame 的类,我基本上是在尝试创建这个 JPanel,它接收信息并在按下提交按钮时发送一个“事件”对象。一切似乎都在工作,除了当我按下提交时,它告诉我我的客户端需要可序列化......(客户端类是一个基本类,它打开到特定端口的连接。它有效,我已经测试过了这不是问题)。我已经序列化了我要发送的所有对象。我不明白为什么我会收到 NotSerializableException。几个小时以来一直试图弄清楚这一点。任何见解将不胜感激。
这是我的代码:
public class WindowGameActual extends JFrame implements ActionListener
{
private final static int PORT = 11114;
private GameState game;
public WindowClient connection;

JTextField difficulty;
JCheckBox check4;

public class WindowClient extends Client
{
public WindowClient(String host) throws IOException
{
super(host, PORT);
}
protected void messageReceived(Object message)
{
if(message instanceof GameState)
{
game = (GameState) message;
container.repaint();
}
}
} //end WindowClient
public WindowGameActual(String host)

setDefaultCloseOperation(EXIT_ON_CLOSE);

// TODO Auto-generated catch block
e.printStackTrace();
}

container.setLayout(gridC);
CurrentEventPanel curEvt = new CurrentEventPanel(game);
curEvt.updateEvent(game);
container.add(curEvt);
// ControlPanel eventControl = new ControlPanel(host);
// container.add(eventControl);
GridLayout outerPanel = new GridLayout(4, 1);
JPanel control = new JPanel();
control.setLayout(outerPanel);
JPanel layer1 = new JPanel();
JLabel eDescription = new JLabel("Describe Event:");
layer1.add(eDescription);
description = new JTextArea("");
description.setEditable(true);
description.setColumns(17);
layer1.add(description);
control.add(layer1);

layer4.add(agl);

// setPreferredSize(new Dimension(200, 20));
UserStatPanel stats = new UserStatPanel(game);

}
public class Event implements Serializable

这是我的错误消息(异常短):
Client send thread terminated by IOException: java.io.NotSerializableException: testGame.WindowGameActual$WindowClient
Client send thread terminated.
Client receive thread terminated.
Hub receive thread terminated by IOException: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: testGame.WindowGameActual$WindowClient
