[spring boot] UnexpectedRollbackException: Transaction silently rolled back because it has been marked as rollback-only

 

error

org.spr.web.ser.han.AbstractHandlerExceptionResolver(logException:208) - Resolved [org.springframework.transaction.UnexpectedRollbackException: Transaction silently rolled back because it has been marked as rollback-only]

 

예외상황

- teamService.saveTeam() 을 호출한다

- teamMemberService.saveTeamMember() 를 호출한다

- teamMemberService.saveTeamMember() 에서 CustomException 예외가 발생할때 catch 하고 로깅하고 다시 throw 한다

- teamService.saveTeam() 에서 CustomException 을 catch 하고 다시 throw 하지 않는다

- 트랜잭션이 커밋될 것으로 예상되지만 트랜잭션이 롤백되면서 UnexpectedRollbackException 예외가 발생한다

 

조치

- unchecked exception (RuntimeException) 을 사용하지 말고 chcked exception (Exception) 을 사용한다
