Java 使用spring issue制作带有菜单栏的摆动框架

我正在使用spring制作一个带有菜单栏的swing框架，我的问题是，当我启动框架时，菜单栏根本没有出现，我将向您展示beans.xml和bean类，请告诉我为什么菜单栏没有出现，我有4个bean，如下所示：

menuitembean：

public class MyMenuItem extends JMenuItem {
private ArrayList<String> menuItemNames;

public MyMenuItem() {   }

public ArrayList<String> getMenuItemNames() {
    return menuItemNames;
}

public void setMenuItemNames(ArrayList<String> menuItemNames) {
    this.menuItemNames = menuItemNames;
   }
}

框架bean：

public class MainFrame extends JFrame {
/**
 * 
 */
private static final long serialVersionUID = 1L;
private MyMenuBar myMenuBar;

@PostConstruct
public void init(){
    this.add(myMenuBar);        
}

public MainFrame() {
}

public MyMenuBar getMyMenuBar() {
    return myMenuBar;
}

public void setMyMenuBar(MyMenuBar myMenuBar) {
    this.myMenuBar = myMenuBar;
  }
}

这是我的bean配置文件beans.xml：

如果代码太长，则表示感谢和抱歉。

setJMenuBar（myMenuBar） 而不是 this.add（myMenuBar）

public class MainFrame extends JFrame {
/**
 * 
 */
private static final long serialVersionUID = 1L;
private MyMenuBar myMenuBar;

@PostConstruct
public void init(){
    this.add(myMenuBar);        
}

public MainFrame() {
}

public MyMenuBar getMyMenuBar() {
    return myMenuBar;
}

public void setMyMenuBar(MyMenuBar myMenuBar) {
    this.myMenuBar = myMenuBar;
  }
}
