Question

我有春季mvc + jpa项目。当我运行这个项目并转到/service链接时，我得到了expiton。我尝试使用@Autowired，但我得到另一个例外，因为使用applicationContext

HTTP Status 500 - Request processing failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.ua.korbo.persistence.repository.PupilRepository] is defined

控制器

@Controller
public class WebController {

    private PupilService pupilService;
    private PupilRepository pupilRepository;
    private ApplicationContext context;

    private void setUpField(){
        System.out.println("1");
        if (context == null){
            System.out.println("2");
            context = new AnnotationConfigApplicationContext(BeanClass.class);
            System.out.println("3");
        }
        System.out.println("4");
        if (pupilService == null){
            System.out.println("5");
            pupilService = context.getBean(PupilServiceImpl.class);
            System.out.println("6");
        }
        System.out.println("7");
        if (pupilRepository == null){
            System.out.println("8");
            System.out.printf(pupilRepository + " start");
            pupilRepository = context.getBean(PupilRepository.class);
            System.out.printf(pupilRepository+" end");
            System.out.println("9");
        }
    }    
@RequestMapping(value = "/service", method = RequestMethod.GET)
    public String printService(Map<String, String> model){
        setUpField();
        pupilService.findAll();
        pupilService.setPupilRepositories(pupilRepository);
        pupilService.save(new Pupil("Name", "Last", "Email", "MSG", "Number"));
        model.put("key", "This is service!");
        return "print";
    }
