                Specifically, beans will be scanned for matches with the ordered list of
                "protect-pointcut" sub-elements, Spring Security annotations and/or. Where there is a
                match, the beans will automatically be proxied and security authorization applied to the

                (ie "protect-pointcut" declarations, expression annotations, @Secured and also JSR250
                security annotations), the metadata sources will be queried in that order. In practical

                annotations. If using annotations, the order of precedence is EL-based (@PreAuthorize
