강의의 3분 30초 경 오류 코드를 수정하는 순서에서의 AutoAppConfig클래스의 3줄을 주석처리 하는 부분을 처리 하였는데도 오류가 떠서 GPT에 검색을 해보니까 주석 처리를 했는데도 memoryMemberRepository Bean이 두개가 등록이 되어있다고 나옵니다.

AutoAppCofig 코드

package hello.core;

import hello.core.member.MemberRepository;
import hello.core.member.MemoryMemberRepository;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;

@Configuration
@ComponentScan(
        excludeFilters = @ComponentScan.Filter(type = FilterType.ANNOTATION, classes = Configuration.class)
)
public class AutoAppConfig {
//    @Bean("memoryMemberRepository")
//    MemberRepository memberRepository() {
//        return new MemoryMemberRepository();
//    }
}

MemberServiceImpl 코드

package hello.core.member;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Component;

@Component
public class MemberServiceImpl implements MemberService{

    private final MemberRepository memberRepository;

    @Autowired // ac.getBean(MemberRepository.class)
    public MemberServiceImpl(MemberRepository memberRepository) {
        this.memberRepository = memberRepository;
    }

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

    @Override
    public Member findMember(Long memberId) {
        return memberRepository.findById(memberId);
    }

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

MemberService 코드

package hello.core.member;

public interface MemberService {

    void join(Member member);

    Member findMember(Long memberId);

}

MemoryMemberRepository 코드

package hello.core.member;

import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Component;

import java.util.HashMap;
import java.util.Map;

@Component
public class MemoryMemberRepository implements MemberRepository{

    private static Map<Long, Member> store = new HashMap<>();

    @Override
    public void save(Member member) {
        store.put(member.getId(), member);
    }

    @Override
    public Member findById(Long memberId) {
        return store.get(memberId);
    }
}
