我尝试从 IntelliJ 中的包文件夹加载 fxml 文件，但仍然不起作用

Question

我有 fxml 文件的包文件夹和 java 文件的视图文件夹。当我将文件放入资源文件夹中时，我可以打开它们，但我无法通过 scenebuilder 将它们与我的控制器链接，但另一方面，当我将其放在资源文件夹中时与名为 view 的 java 文件相同的文件夹，它不会启动，但允许我通过 scenebuilder 链接控制器。

这是代码： //主要调用ViewHandler

package view;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Group;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.paint.Color;
import javafx.stage.Stage;

import java.io.IOException;

public class ViewHandler extends Application {
    @Override
    public void start(Stage stage) throws IOException {
        try
        {
            Parent root = FXMLLoader.load(getClass().getResource("/MainMenu.fxml"));
            FXMLLoader fxmlLoader = new FXMLLoader(ViewHandler.class.getResource("MainMenu.fxml"));

            Scene scene = new Scene(root, Color.BLACK);

            //getting the logo in the left upper corner
            Image icon = new Image("logo.png");//logo has to be in module resources
            stage.getIcons().add(icon);

            //setting the title of the page/ parameters of the window
            stage.setTitle("Main Menu");
            //stage.setFullScreen(true);

            stage.setScene(scene);
            stage.show();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }

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

//控制器
