오늘은 시험을 봤습니다. 매니저님이 오셔서 List형식으로 안받았다는 말씀에 확인해보니

package com.example.test.service;

import com.example.test.dto.MemberResponseDto;
import com.example.test.entity.Member;
import com.example.test.repository.MemberRepository;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;




@Service
@RequiredArgsConstructor
public class MemberService {

        private final MemberRepository memberRepository;

    @Transactional(readOnly = true)
    public List<MemberResponseDto> findAllMember() {
        return memberRepository.findAllByOrderByModifiedAtDesc();
    }




    @Transactional
    public MemberResponseDto findMember(Long id) {
        return memberRepository.findById(id).map(MemberResponseDto::new).orElseThrow(
                () -> new NullPointerException("회원 상세 조회 실패 했습니다.")
        );
        }



    }

진짜네... 그래서 죄송하다고 전하고 바로

package com.example.test.service;

import com.example.test.dto.MemberResponseDto;
import com.example.test.entity.Member;
import com.example.test.repository.MemberRepository;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.ArrayList;
import java.util.List;


@Service
@RequiredArgsConstructor
public class MemberService {

        private final MemberRepository memberRepository;

//    @Transactional(readOnly = true)
//    public List<MemberResponseDto> findAllMember() {
//        return memberRepository.findAllByOrderByModifiedAtDesc();
//    }



    @Transactional(readOnly = true)
    public List<MemberResponseDto> findAllMember() {
        List<Member> members = memberRepository.findAll();
        List<MemberResponseDto> memberResponseDtos = new ArrayList<>();
        for (Member b: members) {
            memberResponseDtos.add(new MemberResponseDto(b));
        }
        return memberResponseDtos;
    }

    @Transactional
    public MemberResponseDto findMember(Long id) {
        return memberRepository.findById(id).map(MemberResponseDto::new).orElseThrow(
                () -> new NullPointerException("회원 상세 조회 실패 했습니다.")
        );
        }



    }

이렇게 수정해서 컨펌받았습니다.

자나깨나 코드조심 다시한번 느꼈습니다 작성 후 코드를 다시 보자!
