How to add custom links to repositories

Hey all,

I'm trying to add a custom link to the repository URL but so far I've been unsuccessful.

Currently I have a custom query in my Repository (using the standard Spring data JPA method of extending single repositories) but now I'd like to expose that query method from within the repository with a HATEOAS link.

For example:

"links": [

    {
        "rel": "concept.search",
        "href": "http://localhost:8080/trialverse/concepts/search"
    },
   {
        "rel": "concept.treatments",
        "href": "http://localhost:8080/trialverse/concepts/treatments"
    }
]

I know you can add a ResourceProcessor<Resource<?>> to add links to a Resource, but is there a similar construct for the repositories themselves?

The issue names no files or tests; start by locating repository resource assembly and the ResourceProcessor<Resource<?>> extension point. Trace how Spring Data JPA custom query methods are exposed, then define a supported mechanism for adding HATEOAS links and tests covering the example repository links.
