使用JNativeHook Mac OS X时的安全性和隐私性问题

您好我正在使用JNativeHook为应用程序添加全局快捷方式，该应用程序在屏幕的右上角显示通知类型jframe。目前我的代码在Eclipse中运行时程序运行得非常好。但是，在导出到可运行的jar文件后，应用程序崩溃了。经过一些谷歌搜索后，我发现我需要将Jar启动器添加到首选项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）。有什么我做错了吗？

以下是我用来添加JNativeHook和keybinds的代码。

主档案：

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

的KeyManager：

    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")) {
        Calendar setup = Calendar.getInstance();
        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};
        GregorianCalendar[] timesT = {new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 9, 30, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 10, 20, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 10, 35, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 11, 00, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 11, 50, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 12, 40, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 14, 15, 0), new GregorianCalendar(setup.get(Calendar.MONTH), setup.get(Calendar.DAY_OF_MONTH), 15, 05, 0), null};

    }


}

}

@Override

}

最后提醒：

    JOptionPane.showMessageDialog(null, "Works!");
        final Timer timer = new Timer(10000, this);
        frame = new JFrame();
        frame.setBounds(100, 100, 250, 100);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    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();

你以新的和有趣的方式滥用事件修饰符;）尝试以下方法：

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

如果您正在使用带有Swing / AWT的JNativeHook，请阅读working with swing wiki部分，了解如何与其进行正确的互动。

解决无障碍问题;在OS X＆lt; 10.9，需要在系统首选项中检查辅助功能复选框。在10.9及更高版本中，您必须单独注册请求可访问性访问的每个应用程序。大多数情况下，这只需要是java运行时，除非你使用包装器启动Java（就像eclipse那样）。
