JavaFX无法加载FXML，找不到资源
JavaFX无法加载FXML，找不到资源
提问于 2018-10-23 05:35:23
我正在尝试将我的FXML文件作为UI元素从此项目结构的子文件夹中加载：
InventoryManagementUI
InventoryManagementUI.Java
Controller
MainMenuController.Java
View
MainMenu.fxml
Model我在按位置获取实际资源时遇到了问题，并尝试了以下方法：
Parent root = FXMLLoader.load(getClass().getResource("View/MainMenu.fxml"));
Parent root = FXMLLoader.load(getClass().getResource("/View/MainMenu.fxml"));
Parent root = FXMLLoader.load(getClass().getResource("inventorymanagementui/View/MainMenu.fxml"));
Parent root = FXMLLoader.load(getClass().getResource("/inventorymanagementui/View/MainMenu.fxml"));以下是我使用...getResource(“/View/MainMenu.fxml”)时的错误日志：
这些尝试是在我的InventoryManagementUI.java文件的start方法中进行的。为什么我无法获取对FXML的引用

事实证明，当我重构代码时，我忘记了将fx:id声明从前面的inventorymanagementui.MainMenu.MainMenuController更改为inventorymanagementui.Controller.MainMenuController
