How do you use sessions with Compojure/Ring?

I'm developing a web application using Compojure and I would hugely appreciate a smal开发者_运维问答l and complete example of storing and retrieving session data.

Many thanks in advance, James.

Here is an example of using both Ring's functional style of working with sessions and using an external library (sandbar) to work with the session through a map style interface:

If you are only interested in the Ring approach then you could replace wrap-stateful-session with wrap-session in this example and that will work.

As the author of sandbar, I prefer the map approach but both styles have their place.
