인프런 커뮤니티 질문&답변

밑의 질문에 참고했는데 저는 다른 에러가 떠서 질문에 남깁니다.

전 import hello.hellospring.aop.TimeTraceAop 까지는 잘되어 있는데

빌드 시에는 package hello.hellospring.aop does not exist로 에러가 떠서 구글에 찾으려해도 어떻게 접근을 해야할지 몰라 곤란하네요 ㅠㅠ

package hello.hellospring;

        this.memberRepository = memberRepository;
    }

    //    @Autowired

    //    @Autowired

    @Bean

        return new MemberService(memberRepository);
    }
