Hibernate JPA and Spring javax.persistence.TransactionRequiredException: no transaction is in progress

I am using Hibernate JPA.

Answer 1

I had this problem, just add @Transacctional annotation not only on the method, also in the class together with your @Service annotation.

for example:

@Service
@Transactional
public class MyService {

}
