问题
I've had good experience with Spring MVC REST with a couple of solid projects delivered. My question is about JAX-RS compliance. Does it matter because Spring is here to stay and I don't foresee (nor have a reason to) having to move away from Spring MVC REST to Jersy or any other JAX-RS impl any time soon. Anything that should force me to think about using JAX-RS implementation as opposed to Spring MVC REST?
回答1:
IMHO, if your web application returns JSON/XML only, there is no big difference. However, if some end points of your web application need to return HTML, Spring MVC is better. The reason I think so is that JAX-RS does not provide any MVC mechanism (AFAIK). Jersey (one of JAX-RS implementations) provides Viewable/Template to support MVC, but it is a Jersey-specific feature and not a part of JAX-RS specification.

Also, this blog may give you some insights.
Jersey JAX-RS MVC Killed the Spring MVC Star

(The conclusion of the blog is different from its title, though.)
EDIT - here's the answer to the question asked:
Standardized annotations
As the 2nd link above says:
Jersey is a JAX-RS implementation, one could swap out Jersey for another provider like RestEasy if desired without much effort. Spring MVC on the other hand has REST web service support but the same is not a JAX-RS implementation and therefore one is tied to Spring MVC.
