Exception running application hrms.controller.HrmsMainApp
附我的项目主程序代码和fxml文件代码：
[一、HrmsMainApp.java
package hrms.controller;
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class HrmsMainApp extends Application {
private Stage primaryStage;
private BorderPane rootLayout;
@Override
public void start(Stage primaryStage) {
this.primaryStage = primaryStage;
this.primaryStage.setTitle("");
initrootLayout();
}
public void initrootLayout() {
try {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(HrmsMainApp.class.getResource("hrms.view/RootLayout.fxml"));
rootLayout = (BorderPane) loader.load();
// Show the scene containing the root layout.
Scene scene = new Scene(rootLayout);
primaryStage.setScene(scene);
primaryStage.show();
} catch (IOException e) {
e.printStackTrace();
}
}
public Stage getPrimaryStage() {
return primaryStage;
}
public static void main(String[] args) {
launch(args);
}
}
