完全无关的异常，同时保存多对多关系原则和php

因此，我的应用程序中有多个实体，它们之间：

产品*-*订单

用户*-1用户角色

命令

产品

class Product
{
    ...
    /**
     * @ManyToMany(targetEntity="Order", mappedBy="products")
     */
    protected Collection $orders;
    ...
    public function __construct()
    {
        $this->orders = new ArrayCollection();
    }

    public function addOrder(Order $order): self
    {
        $this->orders[] = $order;

        return $this;
    }
}

使用者

和用户角色：

class UserRole
{
    /** @Id @Column(type="integer") @GeneratedValue */
    protected $id;
    /** @Column(type="string", nullable=false, unique=true, length=20) */
    protected $name;
    /** @Column(type="integer", unique=true, nullable=false) */
    protected $rolePriority;

    /**
     * Many Users have Many Stores.
     * @ManyToMany(targetEntity="UserRoleAction", inversedBy="user_role_actions", fetch="EAGER", cascade={"persist"})
     */
    protected Collection $userRoleActions;

    /**
     * UserRole constructor.
     */
    public function __construct()
    {
        $this->userRoleActions = new ArrayCollection();
    }
...
}

好的，到目前为止，当我尝试保存包含许多选定产品的新订单时，我的问题如下：

class OrderService
{
    public function createFromRequest(HttpRequest $request)
    {
        ...
        $products = $this->entityManager->getRepository(Product::class)->findWhatever(); //products are coming from this without issues.

        foreach ($products as $product) {
            $order->addProduct($product);
        }
        $this->entityManager->persist($order);
        $this->entityManager->flush();
        return $order;
    }
}

我得到：

Blockquote关联字段“User#$role”的类型“UserRole”的预期值改为“u PHP_complete_Class”

我的意思是，这与其他实体有什么关系？？？我不知道该去哪里公平。有什么建议吗？条令是否在幕后进行了一些完全无关的验证？什么

class UserRole
{
    /** @Id @Column(type="integer") @GeneratedValue */
    protected $id;
    /** @Column(type="string", nullable=false, unique=true, length=20) */
    protected $name;
    /** @Column(type="integer", unique=true, nullable=false) */
    protected $rolePriority;

    /**
     * Many Users have Many Stores.
     * @ManyToMany(targetEntity="UserRoleAction", inversedBy="user_role_actions", fetch="EAGER", cascade={"persist"})
     */
    protected Collection $userRoleActions;

    /**
     * UserRole constructor.
     */
    public function __construct()
    {
        $this->userRoleActions = new ArrayCollection();
    }
...
}

class OrderService
{
    public function createFromRequest(HttpRequest $request)
    {
        ...
        $products = $this->entityManager->getRepository(Product::class)->findWhatever(); //products are coming from this without issues.

        foreach ($products as $product) {
            $order->addProduct($product);
        }
        $this->entityManager->persist($order);
        $this->entityManager->flush();
        return $order;
    }
}
