根据这里已经提供的答案，以下是我实现它的方式:

JFrame frame= new JFrame()
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

// frame stuffs here ...

frame.dispatchEvent(new WindowEvent(frame, WindowEvent.WINDOW_CLOSING));

JFrame获取要关闭的事件，并在关闭时退出。

以编程方式关闭Swing帧的最佳方法是使它的行为与按下“X”按钮时一样。要做到这一点，你需要实现适合你的需要的WindowAdapter，并设置帧的默认关闭操作为什么都不做(DO_NOTHING_ON_CLOSE)。

像这样初始化你的框架:

private WindowAdapter windowAdapter = null;

private void initFrame() {

    this.windowAdapter = new WindowAdapter() {
        // WINDOW_CLOSING event handler
        @Override
        public void windowClosing(WindowEvent e) {
            super.windowClosing(e);
            // You can still stop closing if you want to
            int res = JOptionPane.showConfirmDialog(ClosableFrame.this, "Are you sure you want to close?", "Close?", JOptionPane.YES_NO_OPTION);
            if ( res == 0 ) {
                // dispose method issues the WINDOW_CLOSED event
                ClosableFrame.this.dispose();
            }
        }

        // WINDOW_CLOSED event handler
        @Override
        public void windowClosed(WindowEvent e) {
            super.windowClosed(e);
            // Close application if you want to with System.exit(0)
            // but don't forget to dispose of all resources 
            // like child frames, threads, ...
            // System.exit(0);
        }
    };

    // when you press "X" the WINDOW_CLOSING event is called but that is it
    // nothing else happens
    this.setDefaultCloseOperation(ClosableFrame.DO_NOTHING_ON_CLOSE);
    // don't forget this
    this.addWindowListener(this.windowAdapter);
}

你可以通过发送WINDOW_CLOSING事件来关闭帧，就像这样:

WindowEvent closingEvent = new WindowEvent(targetFrame, WindowEvent.WINDOW_CLOSING);
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(closingEvent);

这将关闭框架，就像“X”按钮被按下。

将问题正文中的内容作为CW答案。

想分享的成果，主要来源于关注camickr的链接。基本上我需要抛出一个WindowEvent。应用程序事件队列上的WINDOW_CLOSING。下面是解决方案的概要

// closing down the window makes sense as a method, so here are
// the salient parts of what happens with the JFrame extending class ..

    public class FooWindow extends JFrame {
        public FooWindow() {
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            setBounds(5, 5, 400, 300);  // yeah yeah, this is an example ;P
            setVisible(true);
        }
        public void pullThePlug() {
                WindowEvent wev = new WindowEvent(this, WindowEvent.WINDOW_CLOSING);
                Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(wev);
        }
    }

// Here's how that would be employed from elsewhere -

    // someplace the window gets created ..
    FooWindow fooey = new FooWindow();
    ...
    // and someplace else, you can close it thusly
    fooey.pullThePlug();

以下是你的选择:

System.exit(0); // stop program
frame.dispose(); // close window
frame.setVisible(false); // hide window

如果你这样做是为了确保用户不能关闭窗口:

frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

然后您应该将pullThePlug()方法更改为

public void pullThePlug() {
    // this will make sure WindowListener.windowClosing() et al. will be called.
    WindowEvent wev = new WindowEvent(this, WindowEvent.WINDOW_CLOSING);
    Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(wev);

    // this will hide and dispose the frame, so that the application quits by
    // itself if there is nothing else around. 
    setVisible(false);
    dispose();
    // if you have other similar frames around, you should dispose them, too.

    // finally, call this to really exit. 
    // i/o libraries such as WiiRemoteJ need this. 
    // also, this is what swing does for JFrame.EXIT_ON_CLOSE
    System.exit(0); 
}

我发现这是唯一的方法，发挥良好的WindowListener和JFrame.DO_NOTHING_ON_CLOSE。

不仅要关闭JFrame，还要触发WindowListener事件，试试这个:

myFrame.dispatchEvent(new WindowEvent(myFrame, WindowEvent.WINDOW_CLOSING));
