Spring Boot使用SystemTray图标 [英] Spring Boot use SystemTray Icons
问题描述
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。
I am setting up a Spring Boot Application and would like to have the host have access to a System Tray Icon with access to some bean Information.
我目前正在尝试使用@Autowired详细信息为我的SystemTrayIcon创建Bean。但是,当我尝试添加SystemTrayIcon时,我得到以下异常:
I currently Tried to Create a Bean for my SystemTrayIcon with the @Autowired details. However When I try to add the SystemTrayIcon I get the following Exception:

有没有SpringBoot应用程序可以访问系统托盘图标的任何方式吗?
Is there any way that a SpringBoot Application can have access to System Tray Icons?
我相信我可以简单地在Main方法中定义它(沿着SpringApplication.run)但是我会无法自动装配我的财产。
I believe I CAN simply define it in the Main method (alongisde the SpringApplication.run) however I would not be able to autowire my properties.
此设置是否可行?
推荐答案
解决方案是,而不是使用 SpringApplication.run(MyConfig.class,args)
,使用以下设置:
The Solution is, rather than using SpringApplication.run(MyConfig.class,args)
, use the following setup:
SpringApplicationBuilder builder = new SpringApplicationBuilder(MyConfig.class);
builder.headless(false);
ConfigurableApplicationContext context = builder.run(args);
要实际添加系统图标,我添加了一个以下类型的bean:
To actually add the System Icon I then added a bean of the followign type:
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();
}
}
}
