FXML Exception error while running my code

以下是您的应用程序包内的主要内容：

package application;

import java.net.URL;

import javax.swing.JOptionPane;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import model.Model;

public class Main extends Application {
    Parent root;
    Scene scene;

    @Override
    public void start(Stage primaryStage) {
        try {
            URL url = getClass().getResource("/view/AddCustomer.fxml");
            root = FXMLLoader.load(url);
            scene = new Scene(root);
            primaryStage.setScene(scene);
            primaryStage.setOnCloseRequest(e -> {
                int save = JOptionPane.showConfirmDialog(null, "Do you want to save changes in the product table?");
                if (save == 0) {
                    Model.getInstance().SaveCustomers();
                    Model.getInstance().SaveSessions();
                    Model.getInstance().SaveAdministrators();
                    Model.getInstance().SaveCoachs();
                }
                System.exit(0);
            });
            primaryStage.show();
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    public static void main(String[] args) {
        launch(args);
    }
}

这是控制器包内的addCustomerController：

package controller;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.control.RadioButton;
import javafx.scene.control.TextField;
import javafx.scene.layout.Pane;

public class AddCustomerController {

    @FXML
    private Button cancelMemberButton;

    @FXML
    private Pane customerPane;

    @FXML
    private RadioButton dailyMemberType;

    @FXML
    private TextField memberDiscountField;

    @FXML
    private RadioButton memberFemaleButton;

    @FXML
    private TextField memberIdField;

    @FXML
    private RadioButton memberMaleButton;

    @FXML
    private TextField memberMobileField;

    @FXML
    private TextField memberNameField;

    @FXML
    private TextField memberNationalityField;

    @FXML
    private RadioButton monthlyMemberType;

    @FXML
    private Button saveMemberButton;

    @FXML
    private RadioButton yearlyMemberType;

    @FXML
    void cancelButtonClick(ActionEvent event) {

    }

    @FXML
    void saveButtonClick(ActionEvent event) {

    }

}

这是视图包内的FXML文件（称为AddCustomer.fxml）：

This is my main inside application package:

你正在使用Gluons的移动工具com.gluonhq.charm.glisten.control.ToggleButtonGroup。你真的想这样做吗？也许使用标准的JavaFX `ToggleGroup` 就足够了。如果你确实想使用Gluons库，那么你必须将这个`implementation 'com.gluonhq:charm-glisten:6.2.2'`添加到你的依赖项中。但请注意，Glisten是一项具有与JavaFX不同许可证的专有产品。

You are using Gluons com.gluonhq.charm.glisten.control.ToggleButtonGroup from their mobile tooling. Do you really want to do that? Maybe using the standard JavaFX `ToggleGroup` would be sufficient. If you really want to use Gluons lib then you have to add this `implementation &#39;com.gluonhq:charm-glisten:6.2.2&#39;` to your dependencies. But note, that glisten is a proprietary offering with a different license than JavaFX.
