I'm new to spring MVC. I'm facing UnsatisfiedDependencyException. I have added stereotype annotations but still I'm facing same issue.
Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userController': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean found for dependency [com.demo.app.service.UserService]: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} looking positive replay.
UserController:
@CrossOrigin
@RestController
public class UserController {
@Autowired(required=true)
private UserService userService;
@RequestMapping(value = { "/userSave" },consumes = {"multipart/form-data"}, method = RequestMethod.POST)
@ResponseBody
public String saveUserDetails(@RequestPart(value="file",required=false) MultipartFile file,
@RequestPart("user")User user,
HttpSession session, HttpServletRequest request,
HttpServletResponse response){
System.out.println("data reached...!");
String result=userService.saveUserData(user,session);
return result;
}
}
UserService:
public interface UserService {
public String saveUserData(User user,HttpSession session);
}
UserServiceImpl:
@Service("userService")
public class UserServiceImpl implements UserService{
@Autowired
UserRepository userRepository;
public String saveUserData(User user,HttpSession session){
String output;
Date regDate=new Date();
user.setRegDate(regDate);
output= userRepository.saveUserData(user);
return output;
}
}
UserRepository:
@Component
@Transactional
public class UserRepository extends BaseRepository{
@Autowired
protected SessionFactory sessionFactory;
public String saveUserData(User user) {
final Session session = (Session) getSessionFactory();
try {
session.beginTransaction();
Query query=session.createQuery("UPDATE User set user_Name =:userName,"
+ "reg_Date =:regDate,img_Id=:imgId");
query.setParameter("userName", user.getUserName());
query.setParameter("regDate", user.getRegDate());
query.setParameter("imgId", user.getImgId());
query.setParameter("emailId", user.getImgId());
session.save(user);
session.getTransaction().commit();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
