如何在javafx中重新加载WebView

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

public class WebViewReloadExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        WebView webView = new WebView();
        WebEngine webEngine = webView.getEngine();

        // 加载初始网页
        webEngine.load("https://www.example.com");

        // 创建一个按钮用于重新加载WebView
        Button reloadButton = new Button("重新加载");
        reloadButton.setOnAction(event -> {
            // 重新加载WebView
            webEngine.reload();
        });

        StackPane root = new StackPane();
        root.getChildren().addAll(webView, reloadButton);

        Scene scene = new Scene(root, 800, 600);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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