- Spring Integration was created by Mark Fisher of SpringSource. - It is an implementation of the patterns described in Enterprise Integration Patterns by Hohpe and Woolf. - The book itself doesn’t give concrete usable components, Spring Integration does this: non invasive declarative
- Endpoints connect application code to the integration framework.
- There is quite some code in the slide. Go over it slowly and promise another look during the demo. TODO enlarge code samples -> two slides
