javax.persistence.TransactionRequiredException: Executing an update/delete query

*

<tx:annotation-driven transaction-manager="tmNlp" />

넣어도 같음

*

org.springframework.transaction.annotation.Transactional

and not javax.transaction.Transactional.

바꿨으나 같아

*

transaction = session.beginTransaction();
int result = query.executeUpdate();
transaction.commit();

성공

*transactional이 동작 안하고 있는거야.

왜?

*  tx

위치가 잘못됐다고..

난 context scan ,t x 모두 servlet 에 있어

순서는 xml 에서 무관할걸?

*

<context:annotation-config />

추가해도 안돼

* DAO d위에 Transactional 선언해도 안돼

https://coderanch.com/t/684651/java/javax-persistence-TransactionRequiredException-Transactional-Class

* Interface 선언 안해서

AOP 적용 안되고 있는건 아닐까. 

=> 아닌데

  책 500p 에도 인터페이스 구현은 안함

* service에 어놑 선언도 아냐

* 엔티티매니저 이용 필요한가?

* openSession 안된대, currentSession..

되네.. 시발

 그 전에

// org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread

이건 뭐였지?

tx 선언 안해서 그랬나??
