在Eclipse外运行jar时，FXML布局不加载 [英] FXML layout not loaded when run jar outside Eclipse

问题描述

我尝试加载我的fxml布局文件如下：

I try to load my fxml layout file as follows:

 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，所有的工作，但是当我使用Ant部署应用程序时，我已经一个错误：

When I run application in Eclipse all works, but when I deployed application with Ant, I've got an error:

建立项目后，我的文件夹结构是：

After building project my folder structure is:

与部署的jar相同

我知道在jar和eclipse中解析路径可能有差异，但是我无法解决这个问题。
我使用Java 1.8和JavaFX 8.

I understand that there might be a problem with difference in resolving path inside jar and in eclipse, but I can't resolve this. I use Java 1.8 and JavaFX 8.

更新1
承认错误我认为它解决路径使用绝对URL（以文件开头：/ C：/ ...），但应该在jar文件中使用相对url。为什么使用绝对路径是主要问题。

UPDATE 1 Accodring to the error I think it resolves path using absolute URL (starts with file:/C:/...), but should use relative url inside jar file. Why it use absolute path is main question.

更新2

有趣的是root布局加载成功，使用相同的代码。

Interesting that root layout loads successfully, with same code..

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。

But inner layout initialization fails.

推荐答案

我使用以下代码

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

它正在工作，因为它应该

and it is working as it should

编辑：查看你的跟踪我认为问题在你的控制器，尝试看看这个
