public class BridgeHandler
- extends AbstractReplyProducingMessageHandler
A simple MessageHandler implementation that passes the request Message
directly to the output channel without modifying it. The main purpose of this
handler is to bridge a PollableChannel to a SubscribableChannel or
vice-versa.
The BridgeHandler can be used as a stopper at the end of an assembly line of
channels. In this setup the output channel doesn't have to be set, but if the
output channel is omitted the REPLY_CHANNEL MUST be set on the
message. Otherwise, a MessagingException will be thrown at runtime.

protected Object handleRequestMessage(Message<?> requestMessage)
- Description copied from class:
AbstractReplyProducingMessageHandler
- Subclasses must implement this method to handle the request Message. The return
value may be a Message, a MessageBuilder, or any plain Object. The base class
will handle the final creation of a reply Message from any of those starting
points. If the return value is null, the Message flow will end here.
