userRepository null ?

Question

Users Microservice - JPA 수강중입니다. 실습 따라서 작성하고 있는데 오류가 나는데 잘 모르겠습니다. UserServiceImpl 에서 ModelMapper mapper = new ModelMapper(); mapper.getConfiguration().setMatchingStrategy(MatchingStrategies. STRICT ); UserEntity userEntity = mapper.map (userDto, UserEntity.class); userEntity.setEncryptedPwd("encrypted_password"); 여기까지 값이 잘 찍히다가   userRepository.save (userEntity); <-- 여기서 오류가 납니다.

UserRepository의 의존성 주입이 안된거 아닐까요?
