Родитель контроллера Symfony4 API

Я реализую приложение под Symfony4 для создания API. Я хочу создать родительский контроллер для CRUD, который будет расширен на другие мои контроллеры, чтобы избежать копирования всего кода CRUD. У вас есть пример? Вот что я уже делал на контроллере.

<?php

namespace App\Controller;

use App\Entity\Article;
use App\Exception\ResourceValidationException;
use FOS\RestBundle\Controller\Annotations as Rest;
use FOS\RestBundle\Controller\FOSRestController;
use FOS\RestBundle\Request\ParamFetcherInterface;
use Nelmio\ApiDocBundle\Annotation\Security;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
use App\Representation\Articles;
use Symfony\Component\Validator\ConstraintViolationList;
use Swagger\Annotations as SWG;

class ArticleController extends FOSRestController
{
    /**
     * @Rest\Get(
     *     path = "/api/articles/{id}",
     *     name = "app_article_show",
     *     requirements = {"id" = "\d+"}
     * )
     * @Rest\View()
     *
     * @SWG\Response(
     *     response=200,
     *     description = "Return article."
     * )
     * @SWG\Tag(name = "Article")
     * @Security(name = "Bearer")
     */
    public function showAction(Article $article)
    {
        return $article;
    }

    /**
     * @Rest\Post(
     *     path = "/api/articles",
     *     name= "app_article_create",
     *  )
     * @Rest\View(StatusCode= 201)
     * @ParamConverter(
     *     "article", converter = "fos_rest.request_body",
     *     options = {
                "validator" = { "groups" = "Create"}
     *     }
     * )
     * @SWG\Response(
     *     response=200,
     *     description = "Create article"
     * )
     * @SWG\Tag(name = "Article")
     * @Security(name = "Bearer")
     */
    public function createAction(Article $article, ConstraintViolationList $violations)
    {
        if (count($violations)) {
            $message = 'The JSON sent contain invalid data: ';
            foreach ($violations as $violation) {
                $message .= sprintf(
                    "Field %s: %s",
                    $violation->getPropertyPath(),
                    $violation->getMessage()
                );
            }
            throw new ResourceValidationException($message);
        }

        $em = $this->getDoctrine()->getManager();

        $em->persist($article);
        $em->flush();

        return $this->view(
            $article,
            Response::HTTP_CREATED,
            [
                'Location' => $this->generateUrl('app_article_create', ['id', $article->getId()], UrlGeneratorInterface::ABSOLUTE_URL)
            ]
        );
    }

    /**

            $paramFetcher->get('keyword'),
            $paramFetcher->get('order'),
            $paramFetcher->get('limit'),

        );

        return new Articles($pager);
    }
}

Спасибо за помощь.
