You need a little more work than that, but it make it possible. Hibernate is not the technology I love the most, but it does some non trivial work like managing the unit of work, graph caching and mapping that can be useful. It is also highly prone to be used wrong by devs. You might not need hibernate, sometimes it might help. It should probably be used less than what you see in the wild, though.
