WSDL vs REST Pros and Cons
...be methods. Instead, I suspect that in order to consume a non-trivial REST-based API, it will be necessary to write by hand a substantial amount of "light-weight" code.
Even when that's all done, you still will have translated human-readable documentation into code, with all the attendant risk that...

Fine-tuning annotation-based autowiring with qualifiers
