我正在尝试启动一个 javafx 窗口,每当我运行它时,我都会收到 java.lang.reflect.InaccessibleObjectException: Unable to make field private javafx.scene.web.WebView com.vendify.FX.FXMLDocumentController.webView accessible: module com.vendify.FX does not "opens com.vendify.FX" to module javafx.fxml
目前,我的设置如下所示:
App.java
package com.vendify.FX;
import java.io.File;
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
/**
* JavaFX App
*/
public class App extends Application {
@Override
public void start(Stage stage) throws IOException {
File webViewFXML = new File("src/main/java/com/vendify/FX/test.fxml");
FXMLLoader loader = new FXMLLoader(webViewFXML.toURI().toURL());
Parent root = loader.load();
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
test.fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.Pane?>
<?import javafx.scene.web.WebView?>
<Pane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/16" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.vendify.FX.FXMLDocumentController">
<children>
<WebView fx:id="webView" layoutX="-1.0" layoutY="61.0" prefHeight="339.0" prefWidth="600.0"/>
</children>
</Pane>
FXMLDocumentController.java
package com.vendify.FX;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.web.WebView;
public class FXMLDocumentController implements Initializable {
@FXML
private WebView webView;
@Override
public void initialize(URL url, ResourceBundle rb) {
System.out.print("\n\n\n\n\n\ninitialize called\n\n\n\n");
// WebEngine engine = webView.getEngine();
// engine.load("http://www.newgrounds.com/");
}
public void reloadPage() {
System.out.print("buttonClicked");
}
}
模块信息.java
module com.vendify.FX {
requires javafx.controls;
requires javafx.fxml;
requires javafx.web;
exports com.vendify.FX;
}
最后是 pom.xml

我在 jdk 14 上运行(高于 jdk 11 的要求),我真的很卡住了。在我的 .fxml 中,如果我删除 fx:controller="com.vendify.FX.FXMLDocumentController"
,它似乎运行良好,但没有正确调用 Initialize(),因此,webView 实际上不会加载页面。
我对这个 javaFX 有点陌生,所以非常感谢任何帮助!
