    public abstract class ExposeBeanNameAdvisors

extends Object

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.
