Interface MessagingAdviceBean

All Superinterfaces:

Ordered

public interface MessagingAdviceBean
extends Ordered

Represents a Spring-managed bean with cross-cutting functionality to be applied to one or more Spring beans with annotation-based message handling methods.

Component stereotypes such as @Controller with annotation handler methods often need cross-cutting functionality across all or a subset of such annotated components. A primary example of this is the need for "global" annotated exception handler methods but the concept applies more generally.
