有些场景在maven构建后没有加载

Question

我正在开发netbeans中的JavaFx应用程序,在netbeans中项目正在构建并运行良好.

我从我的项目中创建了一个构建(mvn包),它完成没有错误,但是当我启动程序时,它没有加载所有场景,并且在这种情况下FXMLLoader返回null值.

所有.fxml文件位于同一文件夹中.

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");

    }

加载屏幕的屏幕控制器:

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;
        }
    }
}

进行以下更改后，我已从 Netbeans 外部成功运行您的应用程序。

首先，我想知道为什么你有编译器插件。因此，我删除了它，并在构建过程中收到“未找到 sun.util.logging.PlatformLogger 的类文件”错误。

您遇到过JavaFX8 - sun.util.logging.PlatformLogger not find Exception in NetBeans 8中所述的问题

你需要修复它。

其次，您所拥有的只是编译阶段，而不是可运行的 jar。

可能有办法使用编译器插件（或通过在类路径中包含其他依赖 jar）来做到这一点，但我发现使用程序集插件创建具有所有依赖项的 jar 更容易。

将以下内容添加到您的 pom.xml

         <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>com.eszik.supervisorserver.main.Main</mainClass>
                    </manifest>
                </archive>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
        </plugin>

接下来，分别运行两个 mvn 命令。

mvn clean install
mvn assembly:single

然后， java -jar target/SuperVisorServer-1.0-SNAPSHOT-jar-with-dependency.jar
