JSON in Query Params or How to Inject Custom Java Types via JAX-RS Parameter Annotations

Although I am not a big fan of sending JSON in other places than in the message body as the entity, for example in query parameter in case of requests, it’s not a rare use-case and the way how it can be solved in JAX-RS 2.0 gives me a nice opportunity to illustrate usage of two new interfaces, ParamConverterProvider and ParamConverter. You can then re-use this approach to inject other media-types or formats your application relies on via @*Param annotations (@MatrixParam, @QueryParam, @PathParam, @CookieParam, @HeaderParam).
