весенняя конфигурация mvc с DAOImpl (org.springframework.beans.factory.UnsatisfiedDependencyException)

Question

Я настраиваю проект Spring MVC с контроллером и службами, когда пытаюсь запустить мой проект на сервере, я получаю исключение следующим образом

org.springframework.beans.factory.UnsatisfiedDependencyException: Ошибка создания компонента с именем operationDAOImp: неудовлетворенная зависимость выражается через поле sessionFactory; вложенное исключение org.springframework.beans.factory.NoSuchBeanDefinitionException: нет доступен квалифицирующий компонент типа 'org.hibernate.SessionFactory': ожидается, по крайней мере, 1 боб, который считается кандидатом autowire Аннотации зависимостей: {@ Org.springframework.beans.factory.annotation.Autowired (обязательно = истина)}

вот мой контроллер

   @RestController
   @RequestMapping(value ="/operations")
   public class OperationsController {

@Autowired
OperationsServiceInter operService;
private HttpHeaders headers = new HttpHeaders();
Map<String, Object> message = null;

@PostMapping(value = "/scat")
public ResponseEntity<Map<String, Object>> addServiceCategory(@RequestBody ServiceCategory servCat) {
    headers = new HttpHeaders();
    message = new HashMap<String, Object>();
    ResponseEntity<Map<String, Object>> responseEntity = null;
    try {
        boolean result = operService.addOrUpdateCategory(servCat);
        if (result) { 
            headers.add("head", "addServiceCategory");
            message.put("status", true);
            message.put("data", "Service category added succesfully");
            responseEntity = new ResponseEntity<Map<String, Object>>(message, headers, HttpStatus.OK);
        } else {
            headers.add("head", "addServiceCategory");
            message.put("status", false);
            message.put("data", "Service category NOT added");
            responseEntity = new ResponseEntity<Map<String, Object>>(message, headers, HttpStatus.OK);
        }

    } catch (Exception e) {
        headers.add("head", "addServiceCategory");
        message.put("status", false);
        message.put("data", "Exception occured");
        responseEntity = new ResponseEntity<Map<String, Object>>(message, headers, HttpStatus.OK);
        e.printStackTrace();
    }
    return responseEntity;
}

}

вот мой сервис Интерфейс и реализации

Интерфейс пакет com.makingDoctors.service;

   import com.makingDoctors.entity.ServiceCategory;

  public interface OperationsServiceInter {

boolean addOrUpdateCategory(ServiceCategory servCat);

   }

реализация сервиса

    @Service
   public class OperationsServiceImp implements OperationsServiceInter {
@Autowired
OperationsDAOInter operDao;
/*service category start*/
@Override
@Transactional
public boolean addOrUpdateCategory(ServiceCategory servCat) {
    return operDao.addOrUpdateCategory(servCat);
}
/*service category end*/
  }

вот моя реализация DAO

    @Repository
     public class OperationDAOImp implements OperationsDAOInter {
@Autowired
private SessionFactory sessionFactory;
private Session currentSession = null; 
private CriteriaBuilder critBuilder;

/*service category start*/
@Override
public boolean addOrUpdateCategory(ServiceCategory servCat) {
    boolean success = false;
    try {
        currentSession = sessionFactory.getCurrentSession();
        currentSession.saveOrUpdate(servCat);
        success=true;
    }
    catch (Exception e) {
        e.printStackTrace();
         success = false;
    }
    return success;
} 
/*service category end*/

}

когда я запускаюсь на сервере, я получаю исключение ниже
