在java中为系统托盘创建单个实例

if (SystemTray.isSupported()) {
    // 系统支持系统托盘功能
} else {
    // 系统不支持系统托盘功能
}

SystemTray tray = SystemTray.getSystemTray();

Image icon = Toolkit.getDefaultToolkit().getImage("path/to/icon.png");
String tooltip = "My Application";
PopupMenu popupMenu = new PopupMenu();

// 添加菜单项
MenuItem menuItem = new MenuItem("Exit");
menuItem.addActionListener(e -> System.exit(0));
popupMenu.add(menuItem);

TrayIcon trayIcon = new TrayIcon(icon, tooltip, popupMenu);

try {
    tray.add(trayIcon);
} catch (AWTException e) {
    System.out.println("无法添加到系统托盘");
}
