JavaFX 运行时异常
JavaFX RunTime Exception
我刚刚使用 SceneBuilder
和 fxml
设计了一个界面。当我 运行 程序时,它给了我错误。我可以知道这个程序有什么问题吗?

这是控制器“它是我在创建项目时预先编写的,直到现在才对其进行编辑”
package com.PCIapp;
import java.io.IOException;
import javafx.fxml.FXML;
public class PrimaryController {
@FXML
private void switchToSecondary() throws IOException {
App.setRoot("secondary");
}
}
这里是主文件
package com.PCIapp;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import java.io.IOException;
/**
* JavaFX App
*/
public class App extends Application {
private static Scene scene;
@Override
public void start(Stage stage) throws IOException {
scene = new Scene(loadFXML("primary"), 1280, 800);
stage.setScene(scene);
stage.setResizable(false);
stage.show();
}
static void setRoot(String fxml) throws IOException {
scene.setRoot(loadFXML(fxml));
}
private static Parent loadFXML(String fxml) throws IOException {
FXMLLoader fxmlLoader = new FXMLLoader(App.class.getResource(fxml + ".fxml"));
return fxmlLoader.load();
}
public static void main(String[] args) {
launch();
}
}
终于找到答案了
它在模块中-info.java 文件
我只需要将这行代码放在那里
requires com.jfoenix;
但要小心一点
当我 运行 使用不同的 Jfoenix 组件的项目时,假设我遇到了“java.lang.reflect.InaccessibleObjectException”
具有大量堆栈跟踪
有人在这里遇到了同样的事情
https://github.com/jfoenixadmin/JFoenix/issues/955
对我来说,因为我在 IntelliJ 上使用 maven,所以我在 VM 选项中添加了这两行
--add-opens
java.base/java.lang.reflect=com.jfoenix
--illegal-access=warn
一切正常
我刚刚使用 SceneBuilder
和 fxml
设计了一个界面。当我 运行 程序时,它给了我错误。我可以知道这个程序有什么问题吗?
