@Transactional을 Interface에 적용한 경우

The Stpring team recommends that you annotate only concrete classeds with the @Transactinal annotation as apposed to annotating interfaces.

 

you certainly can place the @Transactional annotation on an interface( or an interface method),

but this works only as you would expect it to if you use inferface-based proxies.

 

 

1. @Transactional은 interface보다는 구체 class에 사용하는 것을 권장

 

2. interface는, interface-based proxies인 경우만 사용이 가능

 

JPA는 Interface-based proxy의 형태로 적용되기 때문에

 

interface에 @Transactional을 붙여도 문제는 없다.
