Actually, it's the other way around. Hibernate that has to support PostGIS.
For what I know, Hibernate supports spatial objects and PostgreSQL. PostGIS
is probably included.

The hardest thing is (as Steve said) it seems more of a higher level
application thing. PostGIS could leverage a datamodel to separate vertexes,
boundaries, areas, etc and even map what is common for each geometry, but I
think it would be really hard to enforce such dynamic events (editing
mostly).
Congratulations on the great job done!

As Daniel stated, data is crucial to the success of a routing project. The
problem is not to have the road names (usually that is standart) but to have
turn tables and correct information about street flow.
pgRouting will provide you what you need for it, but your dataset must be
