        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        for (String role : rolesArray) {
            boolean hasUserRole = authentication.getAuthorities().stream().anyMatch(r -> r.getAuthority().equals(role));
            if (hasUserRole) {
                result = true;
                break;
            }
        }
    }
    return result;
}
