Spring boot 2 data JPA: Transaction not rolling back [duplicate] - spring

Question

I recently moved from Hibernate to JPA. Now I notice two things in my code.
Methods in my services do not need #Transactional anymore to perform insertion to the database.
Transaction never get rolled back even if there's any exception.

How do I configure so I would require #Transactional annotation and any transaction get rolled back during exceptions ?

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.
