我有一个与Symfony 6的工作项目，我们使用API平台。
我需要使我的实体到一个只有一个端点的API资源，以获取所有我的实体在数据库中的列表。
我的问题是我不明白为什么我的实体不作为API资源出现在127.0.0.1/api和端点不工作太。我试图创建一个新的测试实体与symfony制造商直接作为实体资源，但它不工作太我不明白是什么问题。
我的单位：

<?php

namespace App\Entity;

use ApiPlatform\Metadata\ApiResource;
use Symfony\Component\Serializer\Annotation\Groups;
use App\Repository\BoxTypeRepository;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;

#[ORM\Entity(repositoryClass: BoxTypeRepository::class)]
#[ApiResource]
class BoxType
{
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column]
    private ?int $id = null;

    #[ORM\Column(length: 45)]
    private ?string $name = null;

    #[ORM\Column(length: 45)]
    private ?string $manufacturer = null;

    #[ORM\OneToMany(mappedBy: 'boxTypeId', targetEntity: Box::class)]
    private Collection $boxes;

    public function __construct()
    {
        $this->boxes = new ArrayCollection();
    }

我试着用制造者制造一个新的实体，并直接将其作为API资源，但它不起作用
我尝试升级API平台，但与我的 composer 发生了一些冲突，我不明白
