[질문 내용]
일단은 해결 했습니다.

findAllString 이용하는데 Order를 얘가 모르는 거 같아서..

String jpql = "select o From jpabook.jpashop.domain.Order o join o.member m";

이렇게 패키지경로까지 다 명시해줬더니 인지를 하더라구요..

안 그러면

org.hibernate.query.sqm.UnknownEntityException: Could not resolve root entity 'Order'
	at org.hibernate.query.hql.internal.SemanticQueryBuilder.visitRootEntity(SemanticQueryBuilder.java:1960) ~[hibernate-core-6.2.13.Final.jar:6.2.13.Final]
	at org.hibernate.query.hql.internal.SemanticQueryBuilder.visitRootEntity(SemanticQueryBuilder.java:253) ~[hibernate-core-6.2.13.Final.jar:6.2.13.Final]
...............

얘가 이렇게 Order 인지 못한다고 오류가 뜹니다..

원래 엔티티는 그냥 @Entity 등록 하면 알아서 인지 되는걸로 알고 있었는데..

왜 이런 걸까요?
