Question

为了学习JavaFX，我使用IntelliJ IDEA创建了我的第一个项目，并将项目导出为Eclipse项目。当我在这两个IDE中运行项目时，一切都运行良好。不幸的是，在构建项目并尝试运行.jar或.exe文件后，我得到一个异常，我认为问题出在FXMLLoader中，无法找到fxml文件。

public void initRootLayout() {
        try {
            // Load root layout from fxml file.
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(Main.class.getResource("../view/RootLayout.fxml"));
            rootLayout = (BorderPane) loader.load();
            // Show the scene containing the root layout.
            Scene scene = new Scene(rootLayout);
            primaryStage.setScene(scene);
            primaryStage.show();
            // Give the controller access to the main app.
            RootLayoutController rootLayoutController = loader.getController();
            rootLayoutController.setMain(this);
        } catch (IOException e) {
            showExceptionDialog(e);
        }
        // Try to load last opened person file.
        File file = getPersonFilePath();
        if (file != null) {
            loadPersonDataFromFile(file);
        }
    }

Answer 1

我不认为您的fxml文件与jar一起打包。您应该使用resources文件夹。转到项目设置并设置模块的资源文件夹。
