Question

对于一个项目，我需要使用javaFX创建一个GUI，所以我非常密切地关注了scenebuiler / javaFX的教程，我创建了一个非常基本的GUI。但是负载似乎不起作用并抛出LoadException。我在网上似乎有一些类似的问题，但他们的答案似乎都没有解决我的问题。我已经完成了googleFoo，因为我可以尝试类似的指南和教程，但它不会加载。

我尝试过Parent而不是AnchorPane，getClass而不是Main.class以及加载器的更多变化，我在网上找到了。

package application;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;

public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        try {
            System.out.println("pre load");
            AnchorPane root = (AnchorPane) FXMLLoader.load(Main.class.getResource("/application/testView.fxml"));
            System.out.println("post load");
            Scene scene = new Scene(root);
            scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

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

异常

Answer 1

所以它抱怨丢失的控制器是MyTestController真的不在包中，例如application.MyTestController？

javaFX LoadException
