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

According to this issue comment, this will be addressed in an upcoming release of spring-hateoas.

For now, there's a drop-in replacement for ControllerLinkBuilder available from de.escalon.hypermedia:spring-hateoas-ext in Maven Central.

I can now do this:

import static de.escalon.hypermedia.spring.AffordanceBuilder.*

...

add(linkTo(methodOn(KeyMapController.class).getKeyMap(null)).withRel("keyMaps"));

I pass in null as the parameter value to indicate I want to use a template variable. The name of the variable is automatically pulled from the controller.
