使用 JDK 11+ 运行 Java FX + Spring 启动应用程序时出现问题

问题描述 投票：0回答：2

我一直在尝试将用 Java 8 编写的现有 JavaFX 应用程序升级到 Java 17。我对 Java 模块化系统还是新手。

抛出异常

项目结构

enter image description here

  • MainApplication.java

@SpringBootApplication
public class MainApplication {
    public static void main(String[] args) {
        Application.launch(QBoxApplication.class, args);
    }
}

QBoxApplication.java

public class QBoxApplication extends Application {
    private ConfigurableApplicationContext applicationContext;

    public QBoxApplication() {
    }

    @Override
    public void init() {
        ApplicationContextInitializer<GenericApplicationContext> initializer = applicationContext -> {
            applicationContext.registerBean(Application.class, () -> QBoxApplication.this);
            applicationContext.registerBean(Parameters.class, this::getParameters);
            applicationContext.registerBean(HostServices.class, this::getHostServices);
        };

        applicationContext = new SpringApplicationBuilder()
                .sources(MainApplication.class)
                .initializers(initializer)
                .run(getParameters().getRaw().toArray(new String[0]));
    }

    @Override
    public void stop() {
        applicationContext.close();
        Platform.exit();
    }

    @Override
    public void start(Stage stage) {
        applicationContext.publishEvent(new StageReadyEvent(this, stage));
    }
}

StageInitializer.java

@Component
public class StageInitializer implements ApplicationListener<StageReadyEvent> {
    @Override
    public void onApplicationEvent(StageReadyEvent event) {
        Platform.runLater(() -> showWindow(event));
    }

    private void showWindow(StageReadyEvent event) {
        var parent = new StackPane(new Label("Hello World"));

        var scene = new Scene(parent);
        var stage = event.getStage();

        stage.setScene(scene);
        stage.show();
    }
}

设置

  • JDK 17.0.6
  • 春季启动2.7.1
  • 平台：Windows 11

我按照这些视频中的步骤操作

然而，作为输出，会打开一个空白窗口，同时出现上述异常，而不是窗口中心出现“Hello World”。我不确定我做错了什么。期待大家指点

这很奇怪。该方法存在（在最后），但不知何故，反射/类加载器在 Java 11 或 17 中看不到它。无论如何，我取出了向后移植依赖项，它开始正常。

启动时有趣的消息：

补充：这里有两个现成的模板，包含 JavaFX、Spring Boot 和 Maven/Gradle。

我将感谢 GitHub 上的明星支持它的免费开源，从而帮助您解决问题。 <3
