如何在JavaFX中让左上角的X和Y旋转矩形？

import javafx.animation.KeyFrame;
import javafx.animation.KeyValue;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.scene.transform.Rotate;
import javafx.stage.Stage;
import javafx.util.Duration;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        // 创建一个矩形对象
        Rectangle rectangle = new Rectangle(100, 100, 200, 200);
        rectangle.setFill(Color.TRANSPARENT);
        rectangle.setStroke(Color.BLACK);

        // 创建X轴旋转对象
        Rotate xRotate = new Rotate(0, 0, 0, 0, Rotate.X_AXIS);
        // 创建Y轴旋转对象
        Rotate yRotate = new Rotate(0, 0, 0, 0, Rotate.Y_AXIS);

        // 将旋转对象添加到矩形的变换列表中
        rectangle.getTransforms().addAll(xRotate, yRotate);

        // 创建Timeline对象，控制旋转动画
        Timeline timeline = new Timeline();
        timeline.setCycleCount(Timeline.INDEFINITE);
        timeline.setAutoReverse(true);

        // 创建X轴旋转动画
        KeyValue xKeyValue = new KeyValue(xRotate.angleProperty(), 360);
        KeyFrame xKeyFrame = new KeyFrame(Duration.seconds(3), xKeyValue);
        timeline.getKeyFrames().add(xKeyFrame);

        // 创建Y轴旋转动画
        KeyValue yKeyValue = new KeyValue(yRotate.angleProperty(), 360);
        KeyFrame yKeyFrame = new KeyFrame(Duration.seconds(3), yKeyValue);
        timeline.getKeyFrames().add(yKeyFrame);

        // 创建场景并显示
        Group root = new Group(rectangle);
        Scene scene = new Scene(root, 400, 400);
        primaryStage.setScene(scene);
        primaryStage.show();

        // 启动旋转动画
        timeline.play();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
