Transaction execute 코드 적용

 

기존 플러그인을 신규 구축한 Confluence 에 적용한 후 테스트를 진행하였으나 아래와 같은 에러가 발생 하였다.

org.springframework.orm.hibernate5.HibernateOptimisticLockingFailureException: Object of class [com.atlassian.confluence.pages.Page] with identifier [393407]: optimistic locking failed; nested exception is org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect) : [com.atlassian.confluence.pages.Page#393407]

 

 

확인해 보니 Confluence 가 상위 버전으로 넘어가면서 Transaction 처리 방법이 변경되었다고 한다.
