Solution

You must enable the transaction support (tx:annotation-driven or @EnableTransactionManagement) and declare the transactionManager and it should work through the SessionFactory.

You must add @Transactional into your @RepositoryWith @Transactional in your @Repository Spring is able to apply transactional support into your repository.
