在Eclipse外运行jar时未加载FXML布局

我尝试加载我的fxml布局文件，如下所示：

FXMLLoader loader = new FXMLLoader(); loader.setLocation(getClass().getResource("view/MainLayout.fxml")); AnchorPane personOverview = (AnchorPane) loader.load(); 

当我在Eclipse中运行应用程序时都可以工作，但是当我使用Ant部署应用程序时，我遇到了一个错误：

构建项目后，我的文件夹结构是：

在部署的jar中也一样

我知道在jar和eclipse中解析路径可能存在差异，但我无法解决这个问题。 我使用Java 1.8和JavaFX 8。

更新1根据错误我认为它使用绝对URL解析路径（以文件：/ C：/ …开头），但应该在jar文件中使用相对URL。 为什么它使用绝对路径是主要问题。

更新2

有趣的是根布局成功加载，使用相同的代码..

 FXMLLoader loader = new FXMLLoader(); loader.setLocation(MainApp.class.getResource("view/RootLayout.fxml")); rootLayout = (BorderPane) loader.load(); 

但内部布局初始化失败。

Answer 1

我正在使用以下代码

  FXMLLoader loader=new FXMLLoader(Main.class.getResource("views/MainFrame.fxml")); AnchorPane rootpane=(AnchorPane) loader.load(); 

它正在按预期工作

编辑：看完你的踪迹之后我觉得问题出现在你的控制器中，试着看看这个链接
