Spring Integration - Spring Enterprise Recipes: A Problem Solution Approach - page 342

Most of the code is boilerplate_exposed for configuration. Of note is one method, called
tweet(Tweet) . As you've seen in other places, you're relying on Spring Integration to unbundle the
payload from the Message<T> coming in on a channel and to pass the payload as a parameter to this
method.
The configuration inside the XML application context is strikingly similar to the configuration for
the outbound adapter:
