Even in that case you have to get the db info to the handlers somehow. A lot of demo code I see just hard-codes the db stuff, which is not useful.
I can make it work via middleware, like (partial db db-middleware) then add db-middleware to ring before starting jetty. I'm not sure if this is a good plan, or how the db stuff will handle multiple threads.
