[Spring] @WebMvcTest 오류, jpaAuditingHandler 관련

mockMvc를 이용하여 회원가입 test를 하던 도중 빨간색 글씨로

이런 오류가 발생하여 찾아보았더니 어디서 문제가 생겼는지 발견하려면 오류 로그를 조금 더 위로 올려서 오류를 찾아야 한다고 했다.

 

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaAuditingHandler': Cannot resolve reference to bean 'jpaMappingContext' while setting constructor argument

 

그랬더니 조금 위쪽에 저런 오류가 발생한 것을 찾을 수 있었고 jpaAuditing과 관련하여 문제가 있음을 알게 되었다.

 

나의 경우, User entity를 만들 때 baseEntity로 createdAt, updatedAt을 Auditing 어쩌구로 자동 생성하도록 해주었는데 test에서는 이걸 불러오지 못해서 생기는 오류 같았다. 

 

@WebMvcTest 에러 : JPA metamodel must not be empty!

해당 글을 참고하여, test 위에

@MockBean(JpaMetamodelMappingContext.class)

 어노테이션을 붙여줬더니 오류가 해결되었다.
