Define particular repository classes with EnableJpaRepositories

Question

I've been using @EnableJpaRepositories and I'm interested in opportunity of defining particular classes rather than packages. The reason behind this is the fact that I'm using multi-module project and at the moment have a core module which contains all repository definitions in a separate package:

core/repository/ - Here all repository definitions are stored

In other modules, which have dependency on core module, I use the following definition for fetching repositories:

@EnableJpaRepositories(basePackages ="core.repository")

Apparently using this means fetching definitions for all the repositories which are under core/repository package. However, in some of the packages I need only some of the repositories, not all of them. For now I've moved every single repository definition to a separate package like:

core/repository/user

However I'm interested - is it really possible to define concrete repository classes, but not packages, something like that:

@EnableJpaRepositories(baseClasses ="core.repository.UserRepository")

You can customize loaded repositories by using includeFilters / excludeFilters param.

For example, you can define filters in your EnableJpaRepositories configuration:

@EnableJpaRepositories(basePackages = "core.repository", includeFilters = @ComponentScan.Filter(MyModuleJpaRepo.Class))

and then mark every module repository with appropriate annotation:

@MyModuleJpaRepo
public interface TestRepository extends JpaRepository<Test, Long> { … }
