This is a very simple user management app that leverages annotated Groovy classes as the Hibernate-managed entities. In this case, the annotations are the base JPA annotations, but the Hibernate extensions to JPA can be used as well.
There is no XML anywhere; Hibernate is entirely
configured via setting properties on the plugin. In this case I'm
doing it programmatically in Application.cfc, but in the
real world ColdSpring would be a better solution.
The database connectivity is all provided by the CFML runtime's
standard datasources. Just set the coldFusionDsn property
on the plugin and it will take care of the rest (using the service factory
which is supported by both ColdFusion and Railo).
If you prefer/require, Hibernate can still be configured using the standard
hibernate.cfg.xml file, along with HBM files for individual
entities. You can also supply database connection information in this way
instead of using a CF DSN. You can even mix and match both forms of
configuration.
