依賴注入太遲

Question

我正在使用JavaFX 2與Spring框架一起使用，但是注入發生的很晚。我的控制器被FXML-Loader實例化，Spring控制器的成員變量注入工作，但它工作得太晚了，這意味着在（1）注入中沒有發生，而在（2）注入的確發生了：

public class MainController extends AbstractController 
{ 
    @Autowired 
    public StatusBarController statusbarController; 

    // Implementing Initializable Interface no longer required according to 
    // http://docs.oracle.com/javafx/2/fxml_get_started/whats_new2.htm: 
    private void initialize() { 
     BorderPane borderPane = (BorderPane)getView();   
     borderPane.setBottom(statusbarController.getView()); // (1) null exception! 
    } 

    // Linked to a button in the view 
    public void sayHello() { 
     BorderPane borderPane = (BorderPane)getView();   
     borderPane.setBottom(statusbarController.getView()); // (2) works! 
    } 
} 

任何方式讓Spring在以前的狀態注入statusbarController？我不能讓用戶必須點擊一個按鈕來加載我的GUI ;-)

我AppFactory是這樣的：

@Configuration 
public class AppFactory 
{ 
    @Bean 
    public MainController mainController() throws IOException 
    { 
     return (MainController) loadController("/main.fxml"); 
    } 

    protected Object loadController(String url) throws IOException 
    { 
     InputStream fxmlStream = null; 
     try 
     { 
      fxmlStream = getClass().getResourceAsStream(url); 
      FXMLLoader loader = new FXMLLoader(); 
      Node view = (Node) loader.load(fxmlStream); 
      AbstractController controller = (AbstractController) loader.getController(); 
      controller.setView(view); 
      return controller;    
     } 
     finally 
     { 
      if (fxmlStream != null) 
      { 
       fxmlStream.close(); 
      } 
     } 
    } 
}

，則應該設置的ControllerFactory上FXMLLoader讓你負責的創建控制器實例。
