【问题描述】：

您好，我正在使用 JNativeHook 向在屏幕右上角显示通知类型 jframe 的应用程序添加全局快捷方式。目前我的代码在 Eclipse 中运行时，程序运行良好。但是，在导出到可运行的 jar 文件后，应用程序崩溃了。经过几次谷歌搜索后，我发现我需要将 Jar Launcher 添加到偏好设置中安全窗格的辅助功能部分。

但是现在我遇到了一个新问题。我的程序运行但不接受我的全局快捷方式（按下时没有任何反应）。是不是我做错了什么？

这是我用来添加 JNativeHook 和键绑定的代码。

主文件：

    GlobalScreen.getInstance().addNativeKeyListener(new KeyManager());

密钥管理器：

    private String periodName = new String();


@Override
public void nativeKeyPressed(NativeKeyEvent arg0) {
    // TODO Auto-generated method stub







    if (arg0.getKeyCode() == NativeKeyEvent.VK_5 && NativeInputEvent.getModifiersText(arg0.getModifiers()).equals(
            "Ctrl")) {

        GregorianCalendar cal = new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), setup.get(Calendar.HOUR_OF_DAY), setup.get(Calendar.MINUTE), 0);
        GregorianCalendar[] timesM = {new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 9, 40, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH),10, 30, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 11, 55, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 11, 20, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 12, 15, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 13, 15, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 14, 10, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 15, 05, 0), null};

    JLabel label = new JLabel(Title);
    frame.getContentPane().add(label, BorderLayout.NORTH);

    JLabel lblNewLabel = new JLabel(information);
    frame.getContentPane().add(lblNewLabel, BorderLayout.CENTER);

    JButton btnDismiss = new JButton("Dismiss");
    btnDismiss.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            frame.setVisible(false);
            timer.stop();
        }
    });
    frame.getContentPane().add(btnDismiss, BorderLayout.SOUTH);
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();

    frame.setLocation( (int) (ge.getMaximumWindowBounds().getWidth() -     frame.getWidth()), 25);

    frame.setUndecorated(true);
    frame.setVisible(true);

    timer.start();

您正在以新的有趣方式滥用事件修饰符；）尝试以下操作：

if (arg0.getKeyCode() == NativeKeyEvent.VK_5 && arg0.getModifiers() & NativeInputEvent.CTRL_MASK) {

如果您将 JNativeHook 与 Swing/AWT 一起使用，请阅读working with swing wiki 部分了解如何正确交互。
