postRepository.findAllDesc().toList() → postService.findAllPostsDesc()
- postRepository.findAllDesc().toList()
- toList()를 호출하여 스트림을 리스트로 변환하려고 하는데, 이 과정에서 실제 데이터베이스 연결(LogicalConnection)을 사용
- 테스트 실행 중에 이미 postPost(dto)에서 해당 연결(LogicalConnection)을 닫음
→ org.hibernate.resource.jdbc.internal.LogicalConnectionManagedImpl@5784f6b9 is closed 에러가 발생
- postService.findAllPostsDesc()
- 트랜잭션 처리가 자동으로 이루어짐(findAllPostsDesc: @Transactional(readOnly=true) 선언 됨)
= @Transactional이 선언되어 있으므로 새로운 트랜잭션을 열고 데이터베이스 연결을 유지
