JavaFX通过Exe4J打包为EXE后失败运行

JavaFX failed to run after being packaged as EXE through Exe4J

我用JavaFX构建的项目在编译器中运行良好,但是当我将其打包为EXe可执行文件时却出错了。 运行打包EXE程序时提示的错误信息如下:

java.lang.RuntimeException: Exception in Application start method

发生错误的函数:

 @Override
    public void start(Stage initStage) throws Exception {
        FXMLLoader initFXMLLoader = new FXMLLoader(App.class.getResource("/view/initializationStage.fxml"));
        AnchorPane anchorPane = initFXMLLoader.load();  // line 40
        Scene scene = new Scene(anchorPane);
        JMetroThemeManager.setSceneStyle(scene);
        initStage.setScene(scene);
        initStage.setResizable(false);
        initStage.titleProperty().bind(I18N.createStringBinding("title"));
        initStage.show();
    }

从错误提示来看,好像是读取FXML文件失败,但奇怪的是我在其他项目中用同样的方法读取了FXML文件,打包成EXE可执行文件后就正常了,我就是困惑。

我不知道为什么,但我后来创建了另一个 JavaFX 控制器 class,从旧控制器 class 复制了方法并删除了旧控制器 class,并且问题已解决。
