Spring-data-jpa comes with an already compleate GenericDao (with all the stuff you mentiond), but as far as I know you will need at least a (empty) interface for each concrete dao.

I think the best way would be to stick to the @PersistentContext to handle instances of EntityManagers, and inject them into some third party generic dao. You could write one on your own, use spring-data as mentioned by @Ralph or try libraries like Hades.
