Java SwingFXUtils.toFXImage不是'；不要在罐子里工作

我有一个JavaFX画布，用于使用drawUnit（）方法绘制GameUnit。 当我使用Maven从IntelliJ运行应用程序时，不会发生错误。但是当我编译Jar并运行它时，SwingFXUtils.toFXImage（）方法破坏了我的应用程序。我100%确定问题出在这个方法中，因为我检查了它。SpriteAnimation.nextSprite（）方法返回一个buffereImage

这是主要课程：

public class Game extends Application {
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) {
        stage.setTitle("The Game");
        stage.setFullScreenExitKeyCombination(new KeyCharacterCombination(""));
        stage.setFullScreenExitHint("");
        stage.setFullScreen(true);

        Group root = new Group();
        Scene scene = new Scene(root);

        GameCanvas canvas = new GameCanvas();
        canvas.widthProperty().bind(scene.widthProperty());
        canvas.heightProperty().bind(scene.heightProperty());

        root.getChildren().add(canvas);

        new AnimationTimer() {
            @Override
            public void handle(long now) {
                canvas.clear();
                canvas.drawUnits();
            }
        }.start();

        stage.setScene(scene);

        stage.show();
    }
}

这是GameCanvas类：

public class GameCanvas extends Canvas {
    public void drawUnits(){
        GameData.getAllUnits().forEach(this::drawUnit);
    }

    public void drawUnit(GameUnit unit){
        GraphicsContext context = getGraphicsContext2D();
        SpriteAnimation animation = unit.getAnimation();
        context.drawImage(
                SwingFXUtils.toFXImage(animation.nextSprite(), null),
                unit.getPosition().getX(), unit.getPosition().getY(),
                unit.getWidth(), unit.getHeight()
        );
    }

    public void clear() {
        GraphicsContext context = getGraphicsContext2D();
        context.clearRect(0, 0, getWidth(), getHeight());
    }
}

这是SpriteAnimation类：

public class SpriteAnimation {
    private BufferedImage[] sprites;
    private int counter;
    private int speed;
    private int delay;

    public SpriteAnimation(BufferedImage[] sprites, int speed) {
        this.sprites = sprites;
        this.speed = speed;
        counter = 0;
        delay = 0;
    }

    public BufferedImage nextSprite() {
        if (delay == speed - 1) {
            delay = 0;
            counter++;
        }
        else {
            delay++;
        }
        return sprites[counter % sprites.length];
    }
}

这是ImageLoader类：

public class ImageLoader implements Loader<BufferedImage> {
    private static final Logger LOGGER = Logger.getLogger(ImageLoader.class.getName());

    @Override
    public BufferedImage upload(String pathToResource) {
        try (InputStream inputStream = ImageLoader.class.getClassLoader().getResourceAsStream(pathToResource))
        {
            if (inputStream != null) {
                return ImageIO.read(inputStream);
            }
        } catch (IOException e) {
            LOGGER.log(Level.INFO, "Can not upload image!");
        }
        return null;
    }
}

private static final ImageLoader LOADER = new ImageLoader();


BufferedImage[] unitsImage = {
                LOADER.upload("image/character/TileA1.png"),
                LOADER.upload("image/character/TileA2.png")
        };

项目结构：

查看pom文件后，需要添加：

    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-swing</artifactId>
        <version>11</version>
    </dependency>

我可以在新项目中重现我的问题。现在，我将展示一个完整的示例，其中包含所有代码和pomfile@AntonSorokin太好了，你绝对应该这么做。我怀疑，如果您对pom进行建议的更改，它将解决问题。完成！文章末尾有一个新项目。@AntonSorokin很好，你尝试过建议的更改吗？是的！！！非常感谢你！在pom中添加新模块解决了问题！：）评论不用于扩展讨论；这段对话已经结束。
