How do you deal with composite pattern when using hibernate and domain-driven design?

Does hibernate has support for hierarchical data in a database where

• you use a pa开发者_如何学CrentId
• you use a parentId and an orderId
• you use Modified Preorder Tree Traversal

Hibernate supports Modified Preorder Tree Traversal in that lets you define the left/right properties. It does not support hierarchic queries however, but it's pretty trivial to re-hierarchize objects out of linear query if you order that by left value.

Just found that the feature is in-progress
