public class ReplyProducingMessageHandlerWrapper
extends AbstractReplyProducingMessageHandler
implements ManageableLifecycle
The
AbstractReplyProducingMessageHandler
wrapper around raw MessageHandler
for request-reply scenarios, e.g. @ServiceActivator
annotation configuration.
This class is used internally by Framework in cases when request-reply is important and there is no other way to apply advice chain.
The lifecycle control is delegated to the target
MessageHandler
.
