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

'InventoryController'中可能還有問題。 –
