No transactional EntityManager available and exception InvalidDataAccessApiUsageException

Question

I use spring JPA and custom repository extends JpaRepository, for an very easy function:

@Transactional
void functionA(Book Book){
     repositoryA.deleteByBook(Book);
}

Then

javax.persistence.TransactionRequiredException

would be thrown, with exception message:

No transactional EntityManager available

post your JPA repositories? are you doing dao on the right repository? — Saravana, Jul 11 '16 at 07:45

I get the answer now, it is strange:

Because the function should use "public"
