大家好，我是javafx的新手，我一直在研究一个简单的员工应用......但是当我点击按钮意味着打开一个新阶段时会遇到这个痛苦的错误。这是我的代码

package employee;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.stage.Modality;
import javafx.stage.Stage;
import java.io.IOException;

public class Main extends Application{
private static Stage primaryStage;
private static BorderPane mainLayout;
enter code here

public static void main(String[]args){
    launch(args);
    }

@Override
public void start(Stage primaryStage) throws IOException {
this.primaryStage = primaryStage;
this.primaryStage.setTitle("Employee App");

    showMainView();
    showMainItems();
}

      private void showMainView() throws IOException {

        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(Main.class.getResource("view/MainView.fxml"));
        mainLayout = loader.load();
        Scene scene = new Scene(mainLayout);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

     public static void showMainItems() throws IOException {



        FXMLLoader loader;
        loader = new FXMLLoader();
        loader.setLocation(Main.class.getResource("view/MainItems.fxml"));
        BorderPane mainItemsLayout;
        mainItemsLayout = loader.load();
        mainLayout.setCenter(mainItemsLayout);

    }


     public static void showElectricalScene() throws IOException {

        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(Main.class.getResource("electrical/ElectricalDep.fxml"));
        BorderPane electricalLayout = loader.load();
        mainLayout.setCenter(electricalLayout);

    }

     public static void showMechanicalScene() throws IOException {

    FXMLLoader loader = new FXMLLoader();
    loader.setLocation(Main.class.getResource("mechanical/MechanicalDep.fxml"));
    BorderPane mechanicalLayout = loader.load();
    mainLayout.setCenter(mechanicalLayout);

}


     public static void showAddButtonStage() throws IOException {

    FXMLLoader loader = new FXMLLoader();
    loader.setLocation(Main.class.getResource("view/addNewEmployee.fxml"));
    BorderPane addButton = loader.load();

   // BorderPane root = (BorderPane) FXMLLoader.load(Main.class.getResource("view/addNewEmployee.fxml"));
    Stage addDialogStage= new Stage();
    addDialogStage.setTitle("Add New Employee");
    addDialogStage.initModality(Modality.WINDOW_MODAL);
    addDialogStage.initOwner(primaryStage);
    Scene scene= new Scene(addButton);
    addDialogStage.setScene(scene);
    addDialogStage.showAndWait();

}

}

这是错误

尝试使用完整包加载资源，例如：

loader.setLocation(Main.class.getResource("/employee/view/MainView.fxml"));
