Spring - No EntityManager with actual transaction available for current thread - cannot reliably process 'persist' call

Question

I get this error when trying to invoke \"persist\" method to save entity model to database in my Spring MVC web application. Can\'t really find any post or page in internet

Answer 1

boardRepo.deleteByBoardId(id);

Faced the same issue. GOT javax.persistence.TransactionRequiredException: No EntityManager with actual transaction available for current thread

I resolved it by adding @Transactional annotation above the controller/service.
