why spring boot force to user @Transactional annotation
We have a tree layer, core, biz and api.
in core we have some methods that use entityManager to save, update and more.
In biz layer, we call core methods. and in Api layer, we have rest API controllers that call services.
I can't understand that why we have to use @Transactional annotation when we call methods that multiple times call methods that uses entityManager on it.
If I didn't use @Transactional annotation i will this exception
No EntityManager with actual transaction available for current thread - cannot reliably process 'persist' call
spring-boot jpa transactional
