它指向我的主要课程

package application;

import java.net.URL;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import connection.Conexiune;

public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        try {


            Parent root = FXMLLoader.load(getClass().getResource(
                    "/application/MyView.fxml"));
            Scene scene = new Scene(root);
            scene.getStylesheets().add(
                    getClass().getResource("application.css").toExternalForm());
            primaryStage.setScene(scene);

            primaryStage.setTitle("StarMap v7.5");


            primaryStage.show();
            setUserAgentStylesheet(STYLESHEET_CASPIAN);

            Conexiune.createConnection();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

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

更确切地说这行我不知道为什么因为它工作正常直到现在我所做的是使用场景构建器将另一个imageview添加到界面

Parent root = FXMLLoader.load(getClass().getResource("/application/MyView.fxml"));

任何人都可以帮助我吗？
