RESTful Groovy
The JAX-RS 2.0 specification is part of Java EE 7, but can be used now. It contains the expected annotations for the HTTP verbs (@GET, @POST, and so on) and mechanisms for retrieving variables, but only a few methods for doing hypermedia. This presentation will review those techniques by adding both structural and transitional links to resource representations. Groovy is used to simplify the code and also to implement a MessageBodyWriter for JSON data.
In addition to simplifying the implementation classes, Groovy also supplies a RESTful client class from the HttpBuilder project. That will be used, as well as the native client implementation classes in JAX-RS 2.0, to build Spock tests for RESTful services.
