Spring / Spring Data Access
How does @Transactional works in Spring?
@Transactional annotation is based on AOP concept.
When you annotate a method with @Transactional, Spring dynamically creates a proxy that implements the same interface(s) as the class you are annotating. And when clients make calls into your object, the calls are intercepted and the behaviors gets injected via the proxy mechanism.
@Transactional annotation works similar to transactions in EJB.
