Convenient methods for creating advisors that may be used when autoproxying beans created with the Spring IoC container, binding the bean name to the current invocation. May support a bean() pointcut designator with AspectJ.

Typically used in Spring auto-proxying, where the bean name is known at proxy creation time.
