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.
