fxml中的加載異常

我希望我的inventory_layout加載，當我點擊第一個按鈕，但我得到加載異常，而相同的代碼與其他fxmls工作正常。fxml中的加載異常

控制器的路徑是正確的。 fxml是在正確的地方。

這裏是我的代碼 - 庫存

import javafx.event.ActionEvent; 
import javafx.fxml.FXML; 
import javafx.fxml.FXMLLoader; 
import javafx.scene.Scene; 
import javafx.scene.layout.AnchorPane; 
import javafx.scene.layout.Border; 
import javafx.scene.layout.BorderPane; 
import javafx.scene.layout.Pane; 
import javafx.stage.Modality; 
import javafx.stage.Stage; 
import pharmbooks.Utils.DbSingleton; 
import pharmbooks.Utils.UIController; 

import java.io.IOException; 

public class MainController { 


    @FXML 
    private BorderPane borderPane; 


    @FXML 
    public void initInventory(ActionEvent actionEvent) throws IOException{ 
     UIController<InventoryController> uiController=new UIController<InventoryController>(); 
     uiController.setUp(borderPane,"inventory_layout.fxml"); 

    } 


    public void initPurchase(ActionEvent actionEvent) throws IOException{ 
     UIController<PurchaseController> uiController=new UIController<>(); 
     uiController.setUp(borderPane,"purchase_layout.fxml"); 
    } 

}

UI控制

public class UIController<T> { 

    private T controller; 
    private Pane pane; 
    public T getController() { 
     return controller; 
    } 


    public void setUp(Pane mainPane,String fxmlLocation){ 
     try { 
      FXMLLoader loader = new FXMLLoader(); 
      loader.setLocation(getClass().getClassLoader().getResource(fxmlLocation)); 
      pane = loader.load(); 

      controller = loader.getController(); 

      mainPane.getChildren().clear(); 
      mainPane.getChildren().add(pane); 

     }catch (Exception e){ 
      System.out.println(UIController.class.getSimpleName()+" "+e.toString()); 
     } 
    } }

此代碼在Ubuntu效果很好，但：/

這裏是錯誤：

UIController的JavaFX .fxml.LoadException： /Users/manyamadan/Desktop/Everyth ING/pharmbooks-V2 /目標/類/ inventory_layout.fxml

顯示異常堆棧跟蹤和'inventory_layout.fxml'代碼。 – MBec

'InventoryController'中可能還有問題。 –

嗨，請參閱編輯！ @MBec – ALice

在inventory_layout.fxml中，您設置了fx:id屬性所有表列：

<TableColumn fx:id="batchId" prefWidth="75.0" text="BatchId" /> 
<TableColumn fx:id="packing" prefWidth="75.0" text="packing" /> 
<TableColumn fx:id="quantity" prefWidth="75.0" text="quantity" /> 
<TableColumn fx:id="expiry" prefWidth="75.0" text="expiry" /> 
<TableColumn fx:id="mrp" prefWidth="75.0" text="mrp" />

但InventoryController你不@FXML註釋此組件。不知道這個註釋FXMLLoader將無法將正確的對象注入控制器。正確的代碼：

@FXML 
public TableColumn batchId; 
@FXML 
public TableColumn company; 
@FXML 
public TableColumn name; 
@FXML 
public TableColumn packing; 
@FXML 
public TableColumn quantity; 
@FXML 
public TableColumn expiry; 
@FXML 
public TableColumn mrp;

我猜你NullPointerException在initalize()方法，當您嘗試setCellValueFactory()表列。

我假定你正在訪問fxml資源文件。
