在 Eclipse 之外运行 jar 时未加载 FXML 布局 [英] FXML layout not loaded when run jar outside Eclipse

问题描述

我尝试按如下方式加载我的 fxml 布局文件:

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 中运行应用程序时一切正常，但是当我使用 Ant 部署应用程序时，出现错误:

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

构建项目后，我的文件夹结构是:

After building project my folder structure is:

和部署的jar相同

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.

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根据错误，我认为它使用绝对 URL(以 file:/C:/... 开头)解析路径，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，根布局成功加载，代码相同..

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();

但是内部布局初始化失败.

But inner layout initialization fails.

推荐答案

我正在使用以下代码

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

它正在正常工作

在查看您的跟踪后，我认为问题出在您的控制器中，请尝试查看此链接

edit : after looking at your trace I think problem is in your controller , try having a look at this link
