RSPEC-3749 should be applied to classes annotated with @RestController (which itself includes the annotation @Controller which is already covered)
@RestController would be considered the standard annotation for RESTful APIs today in Spring.
Hello @Daire and welcome to the community!
It makes sense to support @RestController the same way we support @Controller. Ticket created: SONARJAVA-4143.
Thanks for taking the time to report this issue.
Best,
Quentin
