JavaFX-拥有java。朗。反思。执行JavaFX WebView示例代码时调用TargetException

Question

我想在我的javafx项目中尝试webview的功能，但我一直使用java。朗。反思。InvocationTargetException，所以我甚至尝试了jenkov的WebView示例代码。com，我仍然无法运行该应用程序。我的配置有什么问题吗？还是其他问题？

package sample;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.VBox;
import javafx.scene.web.WebView;
import javafx.stage.Stage;

public class Main extends Application {

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

    public void start(Stage primaryStage) {
        primaryStage.setTitle("JavaFX WebView Example");

        WebView webView = new WebView();

        webView.getEngine().load("http://google.com");

        VBox vBox = new VBox(webView);
        Scene scene = new Scene(vBox, 960, 600);

        primaryStage.setScene(scene);
        primaryStage.show();

    }
}

这是我得到的结果：

Answer 1

是的，何塞·佩雷达上面的评论似乎是真的！我也遇到过同样的问题，在将javafx.web添加到我的VM参数后，一切都很好！

这应该是上面问题的答案，以便别人更容易找到！

--module-path "\path\to\your\javafx-sdk\lib" --add-modules=javafx.controls,javafx.web
