php - 如何修复“类 XYZ 不是有效实体或映射的超类”。用教义加入列？

Question

我有以下实体，它是另一个实体的 joinColumn 的一部分。特别是这个实体给出了错误：

类“App\Entity\BankAccount”不是有效的实体或映射的超类。

实体BankAccount.php：

<?php

namespace App\Entity;

use Sylius\Component\Resource\Model\ResourceInterface;

class BankAccount implements ResourceInterface
{
    protected ?int $id = null;

    protected ?string $externalId = null;

    protected ?\DateTime $takenAt = null;

    protected string $IBAN = '';

    protected bool $used = false;

    protected $customer;
    protected ?Purchase $purchase = null;

    /**
     * @return int
     */
    public function getId(): ?int
    {
        return $this->id;
    }

    /**
     * @param int $id
     * @return BankAccount
     */
    public function setId(int $id): BankAccount
    {
        $this->id = $id;
        return $this;
    }

    /**
     * @return string|null
     */
    public function getExternalId(): ?string
    {
        return $this->externalId;
    }

    /**
     * @param string|null $externalId
     * @return BankAccount
     */
    public function setExternalId(?string $externalId): BankAccount
    {
        $this->externalId = $externalId;
        return $this;
    }


    /**
     * @return string
     */
    public function getIBAN(): string
    {
        return $this->IBAN;
    }

    /**
     * @param string $IBAN
     * @return BankAccount
     */
    public function setIBAN(string $IBAN): BankAccount
    {
        $this->IBAN = $IBAN;
        return $this;
    }

    /**
     * @return bool
     */
    public function isUsed(): bool
    {
        return $this->used;
    }

    /**
     * @param bool $used
     * @return BankAccount
     */
    public function setUsed(bool $used): BankAccount
    {
        $this->used = $used;
        return $this;
    }

    /**
     * @return ?\DateTime
     */
    public function getTakenAt(): ?\DateTime
    {
        return $this->takenAt;
    }

    /**
     * @param \DateTime $takenAt
     * @return BankAccount
     */
    public function setTakenAt(?\DateTime $takenAt): BankAccount
    {
        $this->takenAt = $takenAt;
        return $this;
    }

    public function getCustomer()
    {
        return $this->customer;
    }

    /**
     * @return BankAccount
     */
    public function setCustomer($customer): BankAccount
    {
        $this->customer = $customer;
        return $this;
    }

    /**
     * @return Purchase|null
     */
    public function getPurchase(): ?Purchase
    {
        return $this->purchase;
    }

    /**
     * @param Purchase|null $purchase
     * @return BankAccount
     */
    public function setPurchase(?Purchase $purchase): BankAccount
    {
        $this->purchase = $purchase;
        return $this;
    }

}

教义配置src/Resources/config/BankAccount.orm.yml：

App\Entity\BankAccount:
  type: entity
  table: bank_account
  id:
    id:
      type: bigint
      generator:
        strategy: AUTO
  indexes:
    idx_used:
      columns: [ used ]
    idx_external_id:
      columns: [ external_id ]
  fields:
    externalId:
      type: string
      column: external_id
      length: 255
      nullable: true
    IBAN:
      column: iban
      type: string
      length: 255
      nullable: false
    used:
      type: boolean
      nullable: false
      default: false
    takenAt:
      type: datetime
      nullable: true
      column: taken_at
  manyToOne:
    customer:
      targetEntity: App\Entity\Customer
      joinColumn:
        name: customer_id
        referencedColumnName: id
        nullable: true
        unique: false

    purchase:
      targetEntity: App\Entity\Purchase
      joinColumn:
        name: purchase_id
        referencedColumnName: id
        nullable: true
        unique: false

该实体引发此类错误的根本原因是因为它是joinColumnas的一部分targetEntity：

App\Entity\Booking:
  type: entity
  table: booking
  id:
    id:
      type: bigint
      generator:
        strategy: AUTO

  manyToOne:
    bankAccount:
      targetEntity: App\Entity\BankAccount
      joinColumn:
        name: bank_account_id
        referencedColumnName: id
        nullable: true
        unique: false

为了使这个manyToOne -Relation 起作用，还需要做什么？
