无法解析符号' WebView'。 javafx WebView在Intellij Idea中使用Maven
事情很简单。我想在WevView支持下创建一个Javafx项目。
这是我遵循的步骤:
- 打开Intellij,创建新项目,在左侧选择Javafx,然后在右侧选择Maven,完成。
- 我在运行的配置中添加了pom.xml中的javafx Web依赖关系
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-web</artifactId>
<version>16</version>
</dependency>
- ,我创建了一个
application
使用VM选项的配置this- add-modules javafx.web
从此所以问题 - 我运行了该应用程序,预先建立的示例完美地
- 打开了
.fxml
使用Gluon SceneBuilder。 - 添加了WebView,给它一个ID,保存它
- 在控制器类中访问元素,但是有一个错误
错误:
无法解析符号'WebView'
我的控制器类

Scene scene = new Scene(fxmlLoader.load());
stage.setTitle("Hello!");
stage.setScene(scene);
stage.show();
}

launch();

我应该做出什么更改以使WebView正确工作?
The thing is simple. I want to create a javafx project with WevView support.
Here are the steps i followed:
- Open intellij, create new project, select javafx on the left side, and also select maven on the right side, finish.
- I added a javafx web dependency in pom.xml
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-web</artifactId>
<version>16</version>
</dependency>
- In the configuration for running, i created an
Application
configuration with VM option this--add-modules javafx.web
as from this S.O. question - I run the Application and the prebuilt example runs perfectly
- Open the
.fxml
using Gluon SceneBuilder. - Added WebView, gave it an id, saved it
- Access the element in Controller class but there is an error
Error:
Cannot resolve symbol 'WebView'
My Main class
package com.example.webbrowser;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.stage.Stage;
import java.io.IOException;
public class HelloApplication extends Application {
@Override
public void start(Stage stage) throws IOException {
FXMLLoader fxmlLoader = new FXMLLoader(HelloApplication.class.getResource("hello-view.fxml"));
Scene scene = new Scene(fxmlLoader.load());
stage.setTitle("Hello!");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch();
}
}
My Controller class:
package com.example.webbrowser;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import java.net.URL;
import java.util.ResourceBundle;
public class HelloController implements Initializable {
@FXML
private WebView web;
@Override

}
}

将
requires javafx.web;
行添加到module-info.java
中。Add the line
requires javafx.web;
to yourmodule-info.java
