java如何在关闭时关闭webview？JavaFx

Question

 Platform.runLater(() -> {
            WebView wv = new WebView();
            final WebEngine engine = wv.getEngine();
            fxpanel.setScene(new Scene(wv));
            engine.setJavaScriptEnabled(true);
            engine.load(Url);
        };

当我关闭这个框架时，当这个WebView打开时，我可以看到它们在后台运行，所以我尝试在一个公共的void类中这样关闭它，但是它没有正确关闭，所以我怎么做呢

   public static void closeframe() {
    Platform.setImplicitExit(false);
    if (ClassName != null) {
        ClassName.frame.dispose();

        Platform.runLater(() -> {
            wv = new WebView();
            ClassName.wv.getEngine().reload();

            ClassName.wv = null;
            ClassName.frame = null;
        });

在停止方法中退出平台，如下所示：

public class Main extends Application {

    //Entry point to application
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent authScene = (Parent) FXMLLoader.load(getClass().getResource("/View/Auth.fxml"));
        Scene scene = new Scene(authScene);
        primaryStage.setScene(scene);
        primaryStage.setResizable(false);
        primaryStage.setTitle("Green Project : Login Form");
        primaryStage.show();

    }

    @Override
    public void stop() {
        Platform.exit();
    }
}
