Sonar code Smell

Issue-ID: USECASEUI-407

Spring framework 4.3 introduced variants of the @RequestMapping
annotation to better represent the semantics of the annotated methods.
The use of @GetMapping, @PostMapping, @PutMapping, @PatchMapping and
@DeleteMapping should be preferred to the use of the raw
@RequestMapping(method = RequestMethod.XYZ).
