Spring JPA Transaction Manager does not rollback

Question

I recently moved from Hibernate to JPA. Now I notice two things in my code.

1. Methods in my services do not need @Transactional anymore to perform in

Answer 1

The issue was with table engine that's MyISAM. The transaction is able to rollback after I changed the engine to InnoDB.

Setting the hibernate.dialect to org.hibernate.dialect.MySQLInnoDBDialect ensure the creation of table with InnoDBin the future.
