인프런 커뮤니티 질문&답변

안녕하세요 현재 싱글톤 강좌를 시청하고 있습니다.

AppConfig에서 호출관계의 관한 싱글톤 확인 부분에 중 예외가 발생하였고 MemberServiceImpl OrderServiceImpl 확인을 했는데 어떤 부분에서 오류가 발생한지 잘 모르겠습니다.

예외는 다음과 같이 나왔으며

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'memberRepository' available

아래는 MemberServiceImpl OrderServiceImp 그리고 테스트 코드입니다.

public class MemberServiceImpl implements MemberService{

    private final MemberRepository memberRepository;

    public MemberServiceImpl(MemberRepository memberRepository) {
        this.memberRepository = memberRepository;
    }

    @Override
    public void join(Member member) {
        memberRepository.save(member);
    }

    @Override
    public Member findByMember(String userId) {
        return memberRepository.findById(userId);
    }

    public MemberRepository getMemberRepository(){
        return memberRepository;
    }
}

public class OrderServiceImpl implements OrderService{
    private final MemberRepository memberRepository;

    private final DiscountPolicy discountPolicy;
    public OrderServiceImpl(MemberRepository memberRepository, DiscountPolicy discountPolicy) {
        this.memberRepository = memberRepository;
        this.discountPolicy = discountPolicy;
    }
    @Override
    public Order createOrder(String userId, String itemName, int productPrice) {
        Member member = memberRepository.findById(userId);
        int discountPrice = discountPolicy.discount(member , productPrice);
        return new Order(userId , itemName , productPrice , discountPrice);
    }

    public MemberRepository getMemberRepository() {
        return memberRepository;
    }

void configurationTest(){
        ApplicationContext ac = new AnnotationConfigApplicationContext(AppConfig.class);
        MemberServiceImpl memberService = ac.getBean("memberService", MemberServiceImpl.class);
        OrderServiceImpl orderService = ac.getBean("orderService", OrderServiceImpl.class);
        MemberRepository memberRepository = ac.getBean("memberRepository", MemberRepository.class);

        MemberRepository memberRepository1 = memberService.getMemberRepository();
        MemberRepository memberRepository2 = orderService.getMemberRepository();


        System.out.println("memberService -> memberRepository = " + memberRepository1);
        System.out.println("orderService -> memberRepository = " + memberRepository2);
        System.out.println("memberRepository  = " + memberRepository);
    }
