Spring @Service是事务性的吗？

Question

When I am on a spring service and I want to update several database tables through spring repositories, do I need to add @Transactional to make sure I am transactional and rollback or is it already there? If yes, do I need to add it to the class level or method?

Answer 1

The answer is Yes, you need to add it separately. For more details, please refer:
