Declarative transactions (@Transactional) doesn't work with @Repository in Spring

Question

Answer 1

The @Transactional annotation may be placed before an interface definition, a method on an interface, a class definition, or a public method on a class. However, please note that the mere presence of the @Transactional annotation is not enough to actually turn on the transactional behavior - the @Transactional annotation is simply metadata that can be consumed by something that is @Transactional-aware and that can use the metadata to configure the appropriate beans with transactional behavior. In the case of the above example, it is the presence of the element that switches on the transactional behavior.
