The preferred mapping is still one Hibernate Session per HTTP Request.
You would also still need a Filter that instantiates the Session when
the request comes in and closes it when it is finished. But instead of
putting it into the request as an attribute, you can put it into a
ThreadLocal. That way, all methods that need the Session can simply
use the ThreadLocal to get it and you don't have to pass around
request attributes.
