public class DefaultMessageHandlerAdapter<T>
extends AbstractMessageHandlerAdapter<T>
implements org.springframework.core.Ordered

An implementation of MessageHandler that invokes the specified method on the provided target object.

If the method has a non-null return value, a reply message will be generated by the mapper.
