Exception running application survey.Main
J'ai essayé plusieurs approches pour charger le fichier FXML, mais chaque fois la même erreur se produit. J'ai également essayé plusieurs solutions potentielles suggérées par la communauté ici mais aucune ne semble résoudre mon problème. La plupart d'entre eux ont dit que le chemin serait correct, mais je charge le même chemin dans le contrôleur que dans l'application principale et sans handleButtonAction() dans le contrôleur, les applications démarrent correctement. Je suis coincé sur cette tâche de base pendant des heures maintenant. J'utilise IDEA et voici mon code:
principal:
package survey;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
import java.io.IOException;
public class Main extends Application {
private Stage primaryStage;
private BorderPane rootLayout;
@Override
public void start(Stage primaryStage) throws Exception{
this.primaryStage = primaryStage;
this.primaryStage.setTitle("Modul A");
initRootlayout();
showModuleA();
}
private void initRootlayout() throws IOException{
FXMLLoader loader = new FXMLLoader();
loader.setLocation(Main.class.getResource("view/rootLayout.fxml"));
rootLayout = loader.load();
Scene scene = new Scene(rootLayout);
primaryStage.setScene(scene);
primaryStage.show();
}
private void showModuleA() throws IOException {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(Main.class.getResource("view/moduleA.fxml"));
AnchorPane rootPane = loader.load();
rootLayout.setCenter(rootPane);
}
public static void main(String[] args) {
launch(args);
}
}
Controller:
package survey.view;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.fxml.Initializable;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;
import java.awt.event.ActionEvent;
import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;
public class moduleAController implements Initializable {
@FXML private Button bBack;
@FXML private Button bForward;
@FXML
private void handleButtonAction(ActionEvent event) throws IOException{
Stage stage;
Parent root;
if (event.getSource() == bBack){
stage = (Stage) bBack.getScene().getWindow();
root = FXMLLoader.load(getClass().getResource("view/moduleB.fxml"));
} else {
stage = (Stage) bForward.getScene().getWindow();
root = FXMLLoader.load(getClass().getResource("view/moduleA.fxml"));
}
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
@Override
public void initialize(URL location, ResourceBundle resources) {
}

Je vous remercie de toute aide. Merci d'avance!
EDIT: Outre la mauvaise importation d'action de l'événement il y a eu une erreur dans le chemin. Le contrôleur se trouve dans le dossier de vue de sorte que le chemin est juste moduleB.fxml pas vue/moduleB.fxml.
Merci pour l'aide!
Oh mon dieu vous avez raison! Merci. Mais il y avait en fait une autre erreur. Le contrôleur n'est pas dans le dossier principal mais dans le dossier de vue. Ainsi, le chemin était erroné en plus de la mauvaise importation de l'ActionEvent. – jeypeu
