JavaFX：将Spring框架与JavaFX应用程序集成(错误的配置)

我正在开发JavaFX应用程序,我想将Spring功能与其集成.当前代码可以正确编译,但是当我请求标记为@Transactional和@Service的服务层方法时,会得到NullPointerException.我不了解在Spring配置中做错了什么.这是我的JavaFX代码：

主班

public class Main extends Application {

    private static final SpringFxmlLoader loader = new SpringFxmlLoader();

    @Override
    public void start(Stage stage) throws Exception {
       Parent root = FXMLLoader.load(getClass().getClassLoader().getResource("login.fxml"));
        stage.setTitle("APPNAME");
        stage.setScene(new Scene(root, 300, 600));
        stage.setFullScreen(false);
        stage.setMaximized(false);
        stage.show();
    }
    public static void main(String[] args) {
        launch(args);
    }

}


@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages = {"packagename"})
public class ApplicationConfiguration {


    @Bean
    public PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
        Properties properties = new Properties();
        propertySourcesPlaceholderConfigurer.setProperties(properties);
        return propertySourcesPlaceholderConfigurer;
    }

    @Bean
    public MessageSource messageSource() {
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
        messageSource.setBasenames("messages", "org.springframework.security.messages");
        messageSource.setUseCodeAsDefaultMessage(true);
        return messageSource;
    }
}

SpringLoader：

public class SpringFxmlLoader {

    private static final ApplicationContext applicationContext = new AnnotationConfigApplicationContext(ApplicationConfiguration.class);

    public Object load(String url) {
        try (InputStream fxmlStream = SpringFxmlLoader.class
                .getResourceAsStream(url)) {
            System.err.println(SpringFxmlLoader.class
                    .getResourceAsStream(url));
            FXMLLoader loader = new FXMLLoader();
            loader.setControllerFactory(new Callback<Class<?>, Object>() {
                @Override
                public Object call(Class<?> clazz) {
                    return applicationContext.getBean(clazz);
                }
            });
            return loader.load(fxmlStream);
        } catch (IOException ioException) {
            throw new RuntimeException(ioException);
        }
    }
}

现在在我的控制器中,我有类似以下内容：

@Component
public class Controller implements Initializable {
 @FXML
    public TextField usernameField;
    @FXML
    public PasswordField passwordField;
    @FXML
    public Button submitButton;
@Autowired
    private PersonService personService;
// Now the above personService throws me a NPE.
}

我是否以某种方式弄乱了JavaFX的Spring配置.请让我知道.非常感谢.
