Important
When processing Message
, it is often required to chain the incoming
Message
to enable post-processing acknowledgement and metadata
propagation. Use the with
(like withPayload
) methods from the
incoming message, so it copies the metadata and ack/nack methods. It
returns a new Message
with the right content.
