Template variables with ControllerLinkBuilder

Question

I want my response to include this:

\"keyMaps\":{
  \"href\":\"http://localhost/api/keyMaps{/keyMapId}\",
  \"templated\":true
 }

That\'s easy

We've run into the same problem. General workaround is we have our own LinkBuilder class with a bunch of static helpers. Templated ones look like this:

public static Link linkToSubcategoriesTemplated(String categoryId){

    return new Link(
        new UriTemplate(
            linkTo(methodOn(CategoryController.class).subcategories(null, null, categoryId))
                .toUriComponentsBuilder().build().toUriString(),
            // register it as variable
            getBaseTemplateVariables()
        ),
        REL_SUBCATEGORIES
    );
}

private static TemplateVariables getBaseTemplateVariables() {
    return new TemplateVariables(
        new TemplateVariable("page", TemplateVariable.VariableType.REQUEST_PARAM),
        new TemplateVariable("sort", TemplateVariable.VariableType.REQUEST_PARAM),
        new TemplateVariable("size", TemplateVariable.VariableType.REQUEST_PARAM)
    );
}

This is for exposing the parameters of a controller response of a PagedResource.

then in the controllers we call this an append a withRel as needed.
