여긴 memberServiceImpl.class

package hello.core.member;

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 findMember(Long memberId) {
return memberRepository.findById(memberId);
}


//test
public MemberRepository getMemberRepository() {
return memberRepository;
}

}

요긴 ConfigurationSingletonTest.class

package hello.coresingleton;

import hello.core.AppConfig;
import hello.core.member.MemberRepository;
import hello.core.member.MemberService;
import hello.core.member.MemberServiceImpl;
import hello.core.order.OrderServiceImpl;

MemberRepository memberRepository = ac.getBean("memberRepository", MemberRepository.class);

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

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

assertThat(MemberService.getMemberService()).isSameAs(memberRepository); //여기
assertThat(orderService.getMemberRepository()).isSameAs(memberRepository);

}
}
