For spring:
* Move more logic to the decorator.
* Use a fixed operation name, but set the resource name.
* Rename the root span instead of the parent span (If there are other spans in between this could make a difference.) Not sure what impact this would have if multiple controllers are called (ie, forward/include).
For Jax-rs:
* Rename the root span instead of the parent span (same concern as above with spring)
