/**
* Concrete AspectJ transaction aspect using Spring Transactional annotation
* for JDK 1.5+.
*
*
* When using this aspect, you must annotate the implementation class
* (and/or methods within that class), not the interface (if any) that
* the class implements. AspectJ follows Java's rule that annotations on
* interfaces are not inherited.
*
* A @Transactional annotation on a class specifies the default transaction
* semantics for the execution of any public operation in the class.
* A @Transactional annotation on a method within the class overrides the
* default transaction semantics given by the class annotation (if present).
* Any method may be annotated (regardless of visibility).
* Annotating non-public methods directly is the only way
* to get transaction demarcation for the execution of such operations.
