This problem bothers me now for days ..
I'm trying to get the current session from my sessionFactor but receive an org.hibernate.service.UnknownServiceException: Unknown service requested exception.
I have no idea what causes this or what this exception does mean in particular. The exception gets thrown as getCurrentSession()gets called.
@Component
public class RestaurantOwnerRepository implements RestauranOwnerDAO {
private SessionFactory sessionFactory;
public RestaurantOwnerRepository(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
@Override
@Transactional
public List<Restaurant> getAvailableRestaurants(String sessionId) {
Session session = sessionFactory.getCurrentSession();
// ..
}
}
which I am calling in my servlet:
@Configurable
public class RestaurantInformationServiceImpl extends XsrfProtectedServiceServlet implements RestaurantInformationService {
private static final long serialVersionUID = -4088840947018614411L;
private final static Logger logger = Logger.getLogger(RestaurantInformationServiceImpl.class);
@Autowired
public RestauranOwnerDAO restaurantOwnerRepository;
@Override
public void init(ServletConfig config) throws ServletException {
super.init(config);
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("/appServlet/servlet-context.xml");
this.restaurantOwnerRepository = (RestauranOwnerDAO)applicationContext.getBean("restaurantOwnerRepository");
((ConfigurableApplicationContext)applicationContext).close();
}
@Override
public List<RestaurantDTO> getAvailableRestaurants() {
List<Restaurant> availableRestaurants = restaurantOwnerRepository.getAvailableRestaurants(getSessionId());
// ..
}
}
This is my servlet-context.xml file:
