求助！！！socket传输mouseevent和keyevent，结果mouseevent可以传过去，keyevent传不过去，什么鬼啊？？？
异常：
java.io.NotSerializableException: java.io.ObjectOutputStream

代码：
public void keyPressed(KeyEvent e) {
sendEventObject(e);
}

public void sendEventObject(InputEvent event){
    try {
        o.writeObject(event);
        o.flush();
    } catch (IOException e1) {
        e1.printStackTrace();
    }
}
