public class MessageHandlerInterceptorDefinition
extends Object
implements HandlerEnhancerDefinition

HandlerEnhancerDefinition that marks methods (meta-)annotated with MessageHandlerInterceptor as interceptors. These methods need to be given special treatment when invoking handlers. Matching interceptors need to be invoked first, allowing them to proceed the invocation chain.
