Upgrading from 6.6.15.1 to 7.3., jpa integration broken

[Pablo Vidaurri]

I have a custom login webflow that uses JPA to a postgres db. I have the classic entity/repository/service classes. 

I am having continued runtime errors with either 

repository: expected at least 1 bean which qualifies as autowire candidate

or

Entity: Not a managed type

Is JPA working different in CAS 7.3?

I have migrated my configuration classes to src\main\resources\META-INF\spring\org.springframework.boot.autoconfigure.AutoConfiguration.imports

Am I missing something else?
