-Access to session and hibernate-

-getting session-

def sessionFactory

def session = sessionFactory?.getCurrentSession()

RequestContextHolder.currentRequestAttributes().getSession()  

-get hibernate datastore in session-

-Get hibernatedatasource-

hibernate datastore ex.

    hibernateDatastore.getConnectionSources().addConnectionSource(databaseConfiguration.dataSourceName, databaseConfiguration.configuration)
}    

-get table columns-

hibernateDatastore.getSessionFactory().getClassMetadata(GroupCompare).getProperties().sort()

ctx.sessionFactory.getClassMetadata(Team).attributes.collect { it.name }

-get data bindings/properties/class/domain table/declared fields-

def mapping = org.grails.orm.hibernate.cfg.GrailsDomainBinder.getMapping(UserGroup)
