Fix for HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate. dialect' not set. After some research and debugging, I was able to fix it. The part that is missing in the official documentation is that we need to apply the configuration properties to StandardServiceRegistryBuilder .
