Javafx使用Netbeans将fxml资源加载到Jar中

Question

在开始之前，我先说我知道已经列出了许多类似的清单，但没有找到能解决当前问题的清单。

以下所有代码都在我的控制器类之内：

    @FXML
    private void handleButtonAction(ActionEvent event) {
        Button button = (Button)event.getSource();
        String id = button.getId();
        Stage stage = (Stage)button.getScene().getWindow();
        openWindow("AddPartMenu.fxml", stage);
    }


    public void openWindow(String window, Stage stage){
        try{
            Parent root = FXMLLoader.load(getClass().getResource(window));
            Scene scene = new Scene(root);

            System.out.println("Show scene");
            stage.setScene(scene);
            stage.show();
        }catch(Exception e ){
            System.out.println("Failed to open new window: " + e.getMessage());
        }
    }

运行我的应用程序并单击上面代码中列出的按钮时，出现以下错误

Failed to open new window
file:/C:/Users/Tyler/Documents/NetBeansProjects/InventoryManagementUI/dist/run167739486/InventoryManagementUI.jar!/inventorymanagementui/AddPartMenu.fxml

这似乎表明它正在尝试在jar文件中查找引用，但是当我打开jar存档时，"inventorymanagementui/AddPartMenu.fxml"在正确的位置。我从整个情况中得到的是由于某种原因，当我在运行时从Jar内调用getClass().getResource()时，它假定它位于其下两层而不是打包在Jar内（请查看下面的图像以查看暂时将其扁平包装）。我该如何解决这样的问题？

如图所示的当前文件结构

编辑：

这是一张显示NetBeans正在打开的Jar存档的图像

这是通过调用e.printStackTrace（）请求的完整堆栈跟踪

发布完整的堆栈跟踪信息后，问题很明显：您没有为AddPartMenu.fxml设置控制器（或路径不正确）

如果我将错误的fx：controller路径放入我现有的项目中，则会收到相同的错误：

Caused by: javafx.fxml.LoadException: 
file:/F:/Documents/James-Docs/Code/MADContacts/target/MADContacts-1.1-SNAPSHOT.jar!/fxml/Contacts.fxml:17

at javafx.fxml.FXMLLoader.access$700(FXMLLoader.java:103)
at javafx.fxml.FXMLLoader$ValueElement.processAttribute(FXMLLoader.java:922)
etc...
