JavaFX : how to change a scene included in the center of a BorderPane

Question

当我单击超链接时，我想更改主应用程序中边框 Pane 中心的场景。所以我的程序编码如下

private BorderPane borderPane;
    private AnchorPane connectionPage;
    @FXML
    private Hyperlink hyperLink1; 

    @FXML
    private void handleHyperLink1OnAction () {
        try {
            connectionPage=FXMLLoader.load(getClass().getResource("ConnectionViewer.fxml"));
        } catch (Exception e) {
            System.out.println(e.getStackTrace().toString());
            System.out.println(e.getMessage());
        }
        borderPane.setCenter(connectionPage);
    }

这是我的主要应用程序

public void start(Stage primaryStage) throws Exception {
        Parent welcomePage = FXMLLoader.load(getClass().getResource("ManagerWorldViewer.fxml"));

        Scene scene = new Scene(welcomePage);

        primaryStage.setScene(scene);
        primaryStage.show();
    }

一旦我运行这个程序，没有任何变化，也没有发生错误。请帮助我

我错过了 @FXML 注释。所以我将源代码更改为..

@FXML
    private BorderPane borderPane;
@FXML
    private AnchorPane anchorPane;

private void changeScreenOfCenter(String path, VBox menuVBox) {
        VBox getVbox = menuVBox;
        try {
            anchorPane = FXMLLoader.load(getClass().getResource(path));
        } catch (Exception e) {
            System.out.println(e.getStackTrace().toString());
            System.out.println(e.getMessage());
        }
}

并且它有效。
