java – Spring Boot使用SystemTray图标

我正在设置一个Spring Boot应用程序,并希望主机可以访问一个可以访问某些bean信息的系统托盘图标.

我目前尝试使用@Autowired详细信息为我的SystemTrayIcon创建一个Bean.但是,当我尝试添加SystemTrayIcon时,我得到以下异常：

有没有什么方法可以让SpringBoot应用程序访问系统托盘图标？

我相信我可以简单地在Main方法中定义它(沿着SpringApplication.run)但是我无法自动装配我的属性.

这种设置可行吗？

解决方法:

解决方案是,而不是使用SpringApplication.run(MyConfig.class,args),使用以下设置：

    SpringApplicationBuilder builder = new SpringApplicationBuilder(MyConfig.class);
    builder.headless(false);
    ConfigurableApplicationContext context = builder.run(args);

要实际添加系统图标,我添加了一个followign类型的bean：

public class MyTrayIcon extends TrayIcon {

    private static final String IMAGE_PATH = "/path/icon_16x16.png";
    private static final String TOOLTIP = "Text";

    private PopupMenu popup;
    private SystemTray tray;

    public MyTrayIcon(){
        super(createImage(IMAGE_PATH,TOOLTIP),TOOLTIP);
        popup = new PopupMenu();
        tray = SystemTray.getSystemTray();
    }

    @PostConstruct
    private void setup() throws AWTException{
        // popup.add(itemAbout);
        // here add the items to your popup menu. These extend MenuItem
        // popup.addSeparator();
        setPopupMenu(popup);
        tray.add(this);
    }

    protected static Image createImage(String path, String description){
        URL imageURL = MyTrayIcon.class.getResource(path);
        if(imageURL == null){
            System.err.println("Failed Creating Image. Resource not found: "+path);
            return null;
        }else {
            return new ImageIcon(imageURL,description).getImage();
        }
    }
}
