运行应用程序main.main时发生异常
我看到的关于这个问题的大多数帖子都是通过改变getResource()方法中的目录来解决的。我请求你帮助解决这个问题,因为我不知道该怎么办。任何帮助都将不胜感激。
感谢您的事先帮助。感谢@JoséPereda的帮助,我找到了问题的解决方案。问题在于缺少JavaFX Maven插件和VM参数。请阅读本教程。因为您使用的是Maven,所以需要JavaFXMaven插件,如中所示;或者,您需要应用正确的VM参数(请参阅)。最后,对您的资源使用
getClass().getResource(“/main/view.fxml”)
(前提是它位于src/main/resources/main/view.fxml
下)。非常感谢@JoséPereda。添加插件和更改路径解决了我的问题。再次感谢你,你是救命恩人。@trashgood谢谢你的提示。我马上就去做,太好了;我在下面的回答中引用了@JoséPereda的评论,但您可能需要进一步说明如何应用到您的示例中。
