【问题描述】：
我希望你能帮助我，因为我正在寻找并且我迷路了:(
我正在尝试使用 VichUploaderBundle 在我的 symfony 6 项目中上传图像。
但我有这个错误：
类 \"App\\Entity\\Client\" 不可上传。如果您使用注释来配置 VichUploaderBundle，您可能只是忘记在您的实体顶部添加
@Vich\\Uploadable。如果您不使用注释，请检查配置文件是否在正确的位置。在这两种情况下，清除缓存也可以解决问题。我的 vich_uploader.yaml ：
vich_uploader: db_driver: orm mappings: clients_logo: uri_prefix: \'%client_logo%\' upload_destination: \'%kernel.project_dir%/public%client_logo%\' namer: Vich\\UploaderBundle\\Naming\\SmartUniqueNamer我的客户实体：
<?php namespace App\\Entity; use Doctrine\\ORM\\Mapping as ORM; use App\\Repository\\ClientRepository; use Doctrine\\Common\\Collections\\Collection; use Symfony\\Component\\HttpFoundation\\File\\File; use Doctrine\\Common\\Collections\\ArrayCollection; use Vich\\UploaderBundle\\Mapping\\Annotation as Vich; #[ORM\\Entity(repositoryClass: ClientRepository::class)] #[Vich\\Uploadable] class Client { #[ORM\\Id] #[ORM\\GeneratedValue] #[ORM\\Column(type: \'integer\')] private $id; #[ORM\\Column(type: \'integer\')] private $numero_client; /** * Some fields */ /** * NOTE: This is not a mapped field of entity metadata, just a simple property. */ #[Vich\\UploadableField(mapping: \'clients_logo\', fileNameProperty: \'logo\')] private ?File $imageFile = null; #[ORM\\Column(type: \'string\', length: 255, nullable: true)] private $logo; #[ORM\\Column(type: \'datetime\', nullable: true)] private ?\\DateTimeInterface $updatedAt = null; public function __construct() { $this->applis = new ArrayCollection(); } public function getId(): ?int { return $this->id; } public function getLogo(): ?string { return $this->logo; } public function setLogo(?string $logo): self { $this->logo = $logo; return $this; } /** * If manually uploading a file (i.e. not using Symfony Form) ensure an instance * of \'UploadedFile\' is injected into this setter to trigger the update.

<div class=\"col-md-6\"> {{ form_row(form.imageFile, { label: \'Logo\', \'attr\': {\'class\': \'form-control\'} }) }} </div>任何人都可以解释发生了什么？ :(
