이러한 오류가 뜹니다.orderList.html 에서 item.member.name에 접근하려다가 오류가 나는 것 같은데 잘 모르겠어서 질문드립니다.
jpql에서 fetch join으로 item을 강제로 불러오니 해결됐습니다.
하지만
사진과 같이 OSIV를 true로 놓으면 fetch join으로 강제로 불러오지 않아도 해결되는 사례를 보았는데 저의 경우에는 사진과 같이 OSIV 를 true로 바꾸거나, 혹은 지워보기도 했는데 안되더라구요. eager loading은 실무에서 잘 사용하지 않는다고 해서 다른 방법을 찾고있는데, 혹시 jpql을 바꾸지 않고도 해결할 수 있는 방법이 있을까요?
제가 데이터베이스를 H2가 아닌 mariaDB 를 도커에 올려서 사용하고 있는데 이게 관련이 있을 수도 있을까요..
