Расширяет контроллер администратора широкополосного доступа по умолчанию

Я хочу создать свой собственный контроллер для административной части (широкий фреймворк), который расширяет AdminBasicEntityController. Вот мой код контроллера:

    public class AdminArticleController extends AdminBasicEntityController {

    @Autowired
    private ArticleService articleService;

    @Override
    public String addEntity(HttpServletRequest request, HttpServletResponse response, Model model, @PathVariable Map<String, String> pathVars, @ModelAttribute("entityForm") EntityForm entityForm, BindingResult result) throws Exception {
        return super.addEntity(request, response, model, pathVars, entityForm, result);
    }

    @Override
    public String saveEntityJson(HttpServletRequest request, HttpServletResponse response, Model model, @PathVariable Map<String, String> pathVars, @PathVariable("id") String id, @ModelAttribute("entityForm") EntityForm entityForm, BindingResult result, RedirectAttributes ra) throws Exception {
        return super.saveEntityJson(request, response, model, pathVars, id, entityForm, result, ra);
//        articleService.updateArticleEntity();
    }
}

Я также добавил следующий код в файл AdminServletConfig:

@Bean
public AdminBasicEntityController adminBasicEntityController() {
    return new AdminArticleController();
}

И у меня проблема: Мой стек

Что не так с моим контроллером. Я вижу руководство на гид

ОБНОВИТЬ Если я добавлю @RequestMapping({"/admin/pages"}) к уровню класса, методы моего контроллера будут игнорироваться, и будут работать те же методы родительского класса. Почему?

Большое спасибо!
