How can I get Java / Spring MVC to return jsonapi.org ID based format?

Question

I am implementing a JSON API to be used by the Ember-Data REST Adapter.

The Ember-Data REST Adapter needs the JSON returned to follow this format:
http://jsonapi.org/format/

Ember-Data documentation:
http://emberjs.com/guides/models/the-rest-adapter/#toc_json-conventions

I know how to return JSON, say, using Spring MVC 3.2 / Jackson, that's not a problem. However, the JSON format must adhere to the format specified at jsonapi.org.

You can find a sample Django implementation if you google "ember data tastypie adapter" (sorry, not enough reputation points for a link [sic]), and rable also seems to have one.

Seems like jsonapi.org is a much referred to standard for several frameworks / languages.

Do I really need to implement this standard in Java myself?

Any help / pointers would be greatly appreciated.

Many thanks!

There are some JSON:API implementations for Java:

• Katharsis with Spring support but somehow dead for years
• Crnk with Spring Boot 2 support is much more than just JSON:API serializer/deserializer
• JSON:API for Spring HATEOAS based on Spring HATEOAS and Jackson with Boot 2 support, very lightweight but fresh

To clarify I have not used any of the libraries but if I have to I would try the last one from Kai Toedter unless I have the need for a very large system with JSON:API only so I can benefit from all the additional magic.
