Possible to use @RepositoryRestResource with @PathVariable instead of @Param?

I have a RestRepositoryResource which is working properly. However, I would prefer to structure URLs using path variables instead of query parameters. The goal would be this:

http://localhost/persons/findByLastName/Smith/

instead of this:

http://localhost/persons/findByLastName?lastName=Smith

I have played around with various annotations but not achieved this using RestRepositoryResource. Is this possible or does this have to be done with a Controller resource mapping?
