Refine repositoryBaseClass property configuration for @Enable…Repositories repository factory definitions #3423
Description
We should avoid setting the repositoryBaseClass unless it is explicitly configured through @Enable…Repositories. This keeps the customization path for repository factories and factory beans straightforward. In the scenario described in spring-projects/spring-data-jpa#4093, the customization involves a CustomRepositoryFactoryBean that contributes a custom repository factory in order to define the base class globally.
While this setup could be simplified by specifying @Enable…Repositories(repositoryBaseClass = …), our infrastructure currently overrides the repositoryBaseClass with the store-specific variant.
As a result, property values applied to RepositoryFactoryBeanSupport override any properties set in e.g. constructors which prevents local customizations of the repository base class.
