AOP SpringConfig @Bean으로 등록시 에러

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;

@Configuration
public class SpringConfig {

    DataSource dataSource;
    private EntityManager em;
    private final MemberRepository memberRepository;

    @Autowired
    public SpringConfig(MemberRepository memberRepository) {
        this.memberRepository = memberRepository;
    }

    //    @Autowired
//    public SpringConfig(EntityManager em) {
//        this.em = em;
//    }

    //    @Autowired
//    public SpringConfig(DataSource dataSource) {
//        this.dataSource = dataSource;
//    }

    @Bean
    public MemberService memberService() {
        // return new MemberService(memberRepository());
        return new MemberService(memberRepository);
    }

//    @Bean
//    public MemberRepository memberRepository() {
//        // return new MemoryMemberRepository();
//        // return new JdbcMemberRepository(dataSource);
//        // return new JdbcTemplateMemberRepository(dataSource);
//        // return new JpaMemberRepository(em);
//    }

    @Bean
    public TimeTraceAop timeTraceAop() {
        return new TimeTraceAop();
    }
}
