如何在Symfony中继承自定义Doctrine类注释？

<?php

namespace App\Annotation;

/**
 * @Annotation
 * @Target("CLASS")
 */
final class CustomAnnotation
{
    // 添加自定义注释的属性和方法
}

<?php

namespace App\Entity;

use App\Annotation\CustomAnnotation;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @CustomAnnotation
 */
class CustomEntity
{
    // 实体类的属性和方法
}

<?php

namespace App\Annotation;

/**
 * @Annotation
 * @Target("CLASS")
 */
final class CustomAnnotation
{
    private $customProperty;

    public function getCustomProperty()
    {
        return $this->customProperty;
    }
}

<?php

namespace App\Controller;

use App\Entity\CustomEntity;
use Doctrine\Common\Annotations\AnnotationReader;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class CustomController extends AbstractController
{
    /**
     * @Route("/custom", name="custom")
     */
    public function index(): Response
    {
        $reader = new AnnotationReader();
        $reflectionClass = new \ReflectionClass(CustomEntity::class);
        $customAnnotation = $reader->getClassAnnotation($reflectionClass, 'App\Annotation\CustomAnnotation');

        $customProperty = $customAnnotation->getCustomProperty();

        // 使用自定义注释的属性和方法进行进一步处理

        return $this->render('custom/index.html.twig', [
            'customProperty' => $customProperty,
        ]);
    }
}
