我正在netbeans中开发JavaFx应用程序,在netbeans中项目正在构建并运行良好。
我从我的项目做了一个构建(mvn package),它没有错误地完成了,但当我启动程序时,它并没有加载所有的场景,在这种情况下,FXMLLoader返回空值。
同一文件夹中的所有.fxml文件。
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");
}
屏幕控制器加载屏幕的位置:
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;
}
}
}
