public class UserServiceImpl implements UserService {
    private UserDao userDao;
    // @Inject 어노테이션 사용 예시
    @Inject
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }
}

@Service
public class UserServiceImpl implements UserService {
    private UserDao userDao;

    // @Autowired 어노테이션 사용 예시
