Can I get the root Pane from the primary stage?

[willijk]

Firstly thanks for contribute this awesome project.
I have a main page call player.fxml which is a BorderPane.Something like this

<BorderPane xmlns="http://javafx.com/javafx"
            xmlns:fx="http://javafx.com/fxml"
            fx:controller="cn.will.controller.PlayerController"
            fx:id="root"
            prefHeight="670.0" prefWidth="1020.0" stylesheets="@../css/player.css">
    <top>
        <fx:include source="titleBar.fxml"/>
    </top>
    <left>
        <fx:include source="userLeft.fxml"/>
    </left>
    <center>
        <fx:include source="albumDetail.fxml"/>
    </center>
    <bottom>
        <fx:include source="playBar.fxml"/>
    </bottom>
</BorderPane>

In the Main.class I launch the app.

@SpringBootApplication
public class Main extends AbstractJavaFxApplicationSupport implements ApplicationContextAware{

    private static BorderPane root;

    @Autowired
    private ApplicationContext applicationContext;

    public static void main(String[] args) {
        launchApp(Main.class, PlayerView.class, new BlueprintSplashScreen(),args);
    }

    @Override
    public void start(Stage stage) throws Exception {
        super.start(stage);
        stage.getIcons().add(new Image("img/music-icon32.png"));
    }

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.applicationContext = applicationContext;
    }

   // ignore this. It's something I tried to meet my requirement.
   //I  try to use         
   //PlayerView view = applicationContext.getBean(PlayerView .class);
   //root = (BorderPane) view.getView();
   //but it throws NullPointerException dor applicationContext, it seems inject fail
    public ApplicationContext getApplicationContext() {
        return applicationContext;
    }
}

I want to change the center content in the BorderPane dynamically.I really need to get this BorderPane so I can change it.
BTW,I also use Main.showView(xxx.class),but I just want to change the center.Not a whole stage.
Thanks a lot advanced.

The day before I not very familiar with the spingboot anotation so I can confused.Now I know I get use spring factory(anotation) to get the specify view so I can invoke the getView() method,getting the view root pane.
