Sto sviluppando un'applicazione JavaFx in netbeans, in netbeans il progetto sta costruendo e sta funzionando bene.Alcune scene non si caricano dopo la creazione di Maven
Ho creato un build (pacchetto mvn) dal mio progetto senza errori, ma quando lancio il programma non carica tutte le scene e FXMLLoader restituisce con valore null in questo caso.
Tutti i file .fxml nella stessa cartella.
public class JavaFXApplication extends Application {
public static final String TOOLBAR_MAIN = "toolbarMain";
public static final String TOOLBAR_MAIN_FXML = "/fxml/ToolbarMain.fxml";
public static final String TOOLBAR_SUB = "toolbarSub";
public static final String TOOLBAR_SUB_FXML = "/fxml/ToolbarSub.fxml";
public static final String NEW_SESSION_PANEL = "newSession";
public static final String NEW_SESSION_PANEL_FXML = "/fxml/NewSessionPanel.fxml";
public static final String OPEN_SESSION_PANEL = "openSession";
public static final String OPEN_SESSION_PANEL_FXML = "/fxml/OpenSessionPanel.fxml";
public static final String CONNECTIONS_PANEL = "connections";
public static final String CONNECTIONS_PANEL_FXML = "/fxml/ConnectionsPanel.fxml";
public static final String LOGS_PANEL = "logs";
public static final String LOGS_PANEL_FXML = "/fxml/LogsPanel.fxml";
public static final String EXCEPTIONS_PANEL = "exceptions";
public static final String EXCEPTIONS_PANEL_FXML = "/fxml/ExceptionsPanel.fxml";
public static final String MESSAGES_PANEL = "messages";
public static final String MESSAGES_PANEL_FXML = "/fxml/MessagesPanel.fxml";
public static ScreensController menuContainer = new ScreensController();
public static ScreensController contentContainer = new ScreensController();
public static ServerService server = new ServerService();
public static Stage STAGE;
@Override
public void start(Stage primaryStage) throws Exception {
STAGE = primaryStage;
primaryStage.setOnCloseRequest((WindowEvent t) -> {
if (server.isRunning()) {
server.cancel();
}
});
menuContainer.loadScreen(JavaFXApplication.TOOLBAR_MAIN,
JavaFXApplication.TOOLBAR_MAIN_FXML);
menuContainer.loadScreen(JavaFXApplication.TOOLBAR_SUB,
JavaFXApplication.TOOLBAR_SUB_FXML);
contentContainer.loadScreen(JavaFXApplication.NEW_SESSION_PANEL,
JavaFXApplication.NEW_SESSION_PANEL_FXML);
contentContainer.loadScreen(JavaFXApplication.OPEN_SESSION_PANEL,
JavaFXApplication.OPEN_SESSION_PANEL_FXML);
contentContainer.loadScreen(JavaFXApplication.NEW_SESSION_PANEL,
JavaFXApplication.NEW_SESSION_PANEL_FXML);
contentContainer.loadScreen(JavaFXApplication.CONNECTIONS_PANEL,
JavaFXApplication.CONNECTIONS_PANEL_FXML);
contentContainer.loadScreen(JavaFXApplication.LOGS_PANEL,
JavaFXApplication.LOGS_PANEL_FXML);
contentContainer.loadScreen(JavaFXApplication.EXCEPTIONS_PANEL,
JavaFXApplication.EXCEPTIONS_PANEL_FXML);
contentContainer.loadScreen(JavaFXApplication.MESSAGES_PANEL,
JavaFXApplication.MESSAGES_PANEL_FXML);
menuContainer.setScreen(JavaFXApplication.TOOLBAR_MAIN);
contentContainer.setScreen(JavaFXApplication.NEW_SESSION_PANEL);
SplitPane root = new SplitPane();
root.getItems().addAll(menuContainer, contentContainer);
Scene scene = new Scene(root);
primaryStage.setScene(scene);
primaryStage.show();
primaryStage.setResizable(false);
primaryStage.setTitle("Exam Supervisor");
}
regolatore dello schermo in cui gli schermi caricati:
public class ScreensController extends StackPane {
private HashMap<String, Node> screens = new HashMap<>();
public void addScreen(String name, Node screen) {
screens.put(name, screen);
}
public boolean loadScreen(String name, String resource) {
try {
FXMLLoader myLoader = new FXMLLoader(getClass().getResource(resource));
System.out.println("name:" + name + " ,resource" + resource + " ,loader:" + myLoader.getLocation());
Parent loadScreen = myLoader.load();
ControlledScreen myScreenControler
= myLoader.getController();
myScreenControler.setScreenParent(this);
addScreen(name, loadScreen);
return true;
} catch (Exception e) {
System.out.println("name: " + name + ", resource" + resource + " ,exception: " + e.getMessage());
return false;
}
}
public boolean setScreen(final String name) {
if (screens.get(name) != null) {
final DoubleProperty opacity = opacityProperty();
if (!getChildren().isEmpty()) {
getChildren().remove(0);
getChildren().add(0, screens.get(name));
} else {
getChildren().add(screens.get(name));
}
return true;
} else {
System.out.println(screens.get(name) + " ,screen hasn't been loaded!\n");
return false;
}
}
public boolean unloadScreen(String name) {
if (screens.remove(name) == null) {
System.out.println("Screen didn't exist");
return false;
} else {
return true;
}
}

Hai la fxml come sottocartella di risorse: avete la stessa struttura nel file jar che viene creato? –
Sì. La build creata/target/classes/struttura fxml e contiene tutti i file .fxml. –
Non era quello che chiedevo. Nel file jar * generato *, la cartella fxml è di livello superiore o è stata collocata in una cartella delle risorse? –
