JavaFX在通过Exe4J打包成EXE后无法运行。

JavaFX failed to run after being packaged as EXE through Exe4J

问题

项目我使用JavaFX构建的,在编译器中运行良好,但当将其打包为EXE可执行文件时出现问题。

运行打包后的EXE程序时,出现以下错误消息:

java.lang.RuntimeException: Application start 方法中的异常
	at com.sun.javafx.application.LauncherImpl.launchApplication1(LauncherImpl.java:900)
	at com.sun.javafx.application.LauncherImpl.lambda$launchApplication$2(LauncherImpl.java:195)

	at com.sun.glass.ui.win.WinApplication.lambda$runLoop$3(WinApplication.java:174)
	... 1 more

出错的函数:

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

从错误提示看,似乎无法读取FXML文件,但奇怪的是,我在其他项目中使用相同的方法读取FXML文件,将其打包为EXE可执行文件时可以正常工作,这让我感到困惑。

英文:

The project I built with JavaFX worked fine in the compiler, but when I packaged it as an EXe executable, it went wrong.
The error message prompted when running the packaged EXE program is as follows:

java.lang.RuntimeException: Exception in Application start method

Function where the error occurs:

 @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();
}

From the error prompt, it seems that the FXML file failed to read, but strangely enough I have used the same method to read FXML files in other projects and it works fine when packaged into EXE executables, for which I am confused.

答案1

得分: 0

我不知道为什么,但后来我创建了另一个JavaFX控制器类,复制了旧控制器类中的方法,然后删除了旧控制器类,问题就解决了。

英文:

I don't know why, but I later created another JavaFX controller class, copied the methods from the old controller class and deleted the old controller class, and the problem was solved.
