春季靴; FXMLLoader抛出错误ExceptionInInitializerError：null

Question

我有加载FXML文件和控制器的基本类。当我尝试运行测试时，它会抛出ExceptionInInitializerError：null。如果我评论loader.setControllerFactory(context::getBean);，则没有错误。有没有人知道什么是错的？感谢帮助！

用于加载FXML文件和控制器的类：

@Component
public class FXMLreader {
private final ApplicationContext context;
private final ResourceBundle resourceBundle;

@Autowired
public FXMLreader(ApplicationContext context, ResourceBundle resourceBundle) {
    this.context = context;
    this.resourceBundle = resourceBundle;

}

public Parent load(String fxmlPath) throws IOException{

    FXMLLoader loader = new FXMLLoader();      
    loader.setLocation(getClass().getResource(fxmlPath));       
    loader.setControllerFactory(context::getBean);
    loader.setResources(resourceBundle);

    Parent parent = loader.load();

    return parent;
}
}

测试类：

@RunWith(SpringRunner.class)
@SpringBootTest

public class FXMLreaderTest {

   @Autowired
   FXMLreader fXMLreader;

   public FXMLreaderTest() {
   }


@Test
public void test(){
    try {
        Parent parent  = fXMLreader.load("/fxml/Login.fxml");
        assertNotEquals(null, parent);
    } catch (IOException ex) {
          Logger.getLogger(FXMLreaderTest.class.getName()).log(Level.SEVERE, null, ex);
    }
}

}

主要课程

@SpringBootApplication
@EnableAspectJAutoProxy
public class MainAppClass extends Application{
private static final Logger LOG = Logger.getLogger(MainAppClass.class);

protected ConfigurableApplicationContext springContext;

@Override
public void init() throws Exception{
    springContext = SpringApplicationContext();
}

@Override
public void start(Stage primaryStage) throws Exception {

}

@Override
public void stop() throws Exception{
    springContext.close();
}

public static void main(String[] args) {
    launch(args);
}

private ConfigurableApplicationContext SpringApplicationContext() {
    SpringApplicationBuilder builder = new SpringApplicationBuilder(MainAppClass.class);
    String[] args = getParameters().getRaw().stream().toArray(String[]::new);
    builder.profiles("dev");
    return builder.run(args);
}
