JAVAFX加載異常，同時打開一個新的階段

-1

你好傢伙是新來的javafx，我一直在努力一個簡單的員工應用程序......但有這個痛苦的錯誤，當我點擊一個按鈕意味着打開一個新的階段。這裏是我的代碼JAVAFX加載異常，同時打開一個新的階段

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(); 

} 

}

這裏是錯誤

的錯誤是在你的FXML文件（'addNewEmployee.fxml'），這似乎是空的。 –

謝謝，那正是錯誤發生的地方。我有一個空的（addNewEmployee.fxml） –

您可能會發現http://stackoverflow.com/q/3988788/2775450通常有助於使用堆棧跟蹤來排除故障。 –

嘗試用全包加載資源，例如：

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