spring data can create implementations of @repository interfaces of various flavors. spring boot handle of long @repositories included in same package (or sub-package) of @enableautoconfiguration class.
spring boot tries guess location of @repository definitions, based on @enableautoconfiguration finds. more control, use @enablejparepositories annotation (from spring data jpa).
since webinitializer class doesn't provide configuration class annotated @enableautoconfiguration need add @enablejparepositories annotation config class, e.g. add datasourceconfig.
