Template variables with ControllerLinkBuilder

Question

I want my response to include this:

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

That\'s easy

Answer 1

I needed to include a link with template variables in the root of a spring data rest application, to get access via traverson to an oauth2 token. This is working fine, maybe useful:

@Component
class RepositoryLinksResourceProcessor implements ResourceProcessor {

    @Override
    RepositoryLinksResource process(RepositoryLinksResource resource) {

        UriTemplate uriTemplate =  new UriTemplate(
                ControllerLinkBuilder.
                        linkTo(
                                TokenEndpoint,
                                TokenEndpoint.getDeclaredMethod("postAccessToken", java.security.Principal, Map )).
                        toUriComponentsBuilder().
                        build().
                        toString(),
                new TemplateVariables([
                        new TemplateVariable("username", TemplateVariable.VariableType.REQUEST_PARAM),
                        new TemplateVariable("password", TemplateVariable.VariableType.REQUEST_PARAM),
                        new TemplateVariable("clientId", TemplateVariable.VariableType.REQUEST_PARAM),
                        new TemplateVariable("clientSecret", TemplateVariable.VariableType.REQUEST_PARAM)
                ])
        )

        resource.add(
                new Link( uriTemplate,
                        "token"
                )
        )

        return resource
    }
}
