@Autowired 필드 명, @Qualifier, @Primary 강의중 질문드립니다.

안녕하세요.

강의를 들으면서 라이브 코딩을 하며 오류가 계속 발생해 문의드립니다.

@Component
public class OrderServiceImpl implements OrderService {

    private final MemberRepository memberRepository;
    private final DiscountPolicy discountPolicy;

    @Autowired
    public OrderServiceImpl(MemberRepository memberRepository,DiscountPolicy discountPolicy) {
        this.memberRepository = memberRepository;
        this.discountPolicy = discountPolicy;
    }

    @Override
    public Order createOrder(Long memberId, String itemName, int itemPrice) {
        Member member = memberRepository.findById(memberId);
        int discountPrice = discountPolicy.discount(member, itemPrice);
        return new Order(memberId, itemName, itemPrice, discountPrice);
    }

    //테스트 용도
    public MemberRepository getMemberRepository() {
        return memberRepository;
        }
    }

@Component
@Primary
public class RateDiscountPolicy implements DiscountPolicy {

    private int discountPercent = 10;

    @Override
    public int discount(Member member, int price) {
        if (member.getGrade() == Grade.VIP) {
            return price * discountPercent / 100;
        } else {
            return 0;
        }
    }
}

@Component
public class FixDiscountPolicy implements DiscountPolicy {

    private int discountFixAmount = 1000; //1000원 할인

    @Override
    public int discount(Member member, int price) {
        if (member.getGrade() == Grade.VIP) {
            return discountFixAmount;
        } else {
            return 0;
        }
    }
}

이렇게 작성이 되어있지만 AutoConfigTest에서 NoSuchBeanDefinitionException 가 발생해 문의드립니다.

public class AutoAppConfigTest {

    @Test
    void basicScan() {
        ApplicationContext ac = new AnnotationConfigApplicationContext(AutoAppConfig.class);

        MemberService memberService = ac.getBean(MemberService.class);
        assertThat(memberService).isInstanceOf(MemberService.class);

        OrderServiceImpl bean = ac.getBean(OrderServiceImpl.class);
        MemberRepository memberRepository = bean.getMemberRepository();
        System.out.println("memberRepository = " + memberRepository);
    }
}
