MemberServiceTest에서 중복_회원_예외 처리 에러

Question

MemberServiceTest에서

회원가입 test는 성공하는데,

중복_회원_예외 테스트에서 실패합니다.

try catch를 했는데

emberService.join(member2); 
이 부분에서
아래와 같은 에러가 발생합니다.

org.springframework.dao.DataIntegrityViolationException: could not execute statement; SQL [n/a]; constraint [null]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement

왜 그러는 걸까요?ㅠ

Answer

말씀해주신대로 Member Entity에 에러가 있었습니다.^^

해결되었습니당~감사합니당ㅎㅎ

저는 아직 에러 메세지 보는 데에 익숙하지 않은데;;

역시 바로 보시자마자 아는 갓영한님!

에러 해결되었으니 강의 진도 쭉쭉 나가겠습니당!! 감사합니당^.^

Answer

뭔가 조금 이상하네요.

MemberRepository.findByName() 이라는 것이 실행되었는데, insert into orders가 호출되네요.

Caused by: org.h2.jdbc.JdbcSQLIntegrityConstraintViolationException: NULL not allowed for column "ORDER_ID"; SQL statement:

insert into orders (name, member_id) values (?, ?) [23502-200]

Member 엔티티와 MemberRepository.findByName() 메서드를 다시한번 확인해보시겠어요?

만약 문제를 찾지 못하면 Member 엔티티와 MemberRepository를 남겨주세요.

안녕하세요. 갓영한 선생님^^

1번,2번,3번 코드 모두 보여 드립니다.

Answer

안녕하세요. wndud님

1. memberService 코드를 한번 확인해보시겠어요?

2. 테스트 케이스의 모든 코드를 다 보여주시겠어요?

3. 오류 로그를 모두 보여주시겠어요?

감사합니다.
