dependency-injection - symfony 3 传递给 [some service]::__construct() 的参数 1 必须是给定的 Doctrine\ORM\EntityRepository [something] 实例的实例

Question

我正在尝试创建服务:

<?php

namespace AppBundle\Service;

use AppBundle\Repository\GroupEntityRepositoryInterface;
use AppBundle\Repository\GroupUserRepository;
use AppBundle\Repository\GroupUserRepositoryInterface;
use AppBundle\Entity\Group;
use AppBundle\Repository\GroupRepository;


class GroupUserService
{
    private $groupRepository;
    private $groupUserRepository;



    /**
     * @param GroupRepositoryInterface $groupRepository
     * @param GroupUserRepositoryInterface $groupUserRepository
     */
    public function __construct(GroupRepository $groupRepository /*,  GroupUserRepositoryInterface $groupUserRepository*/)
    {
        $this->groupRepository = $groupRepository;
        // $this->groupUserRepository = $groupUserRepository;
    }

    public function deleteGroup(Group $group)
    {
        $this->groupRepository->delete($group);
    }

    public function createGroup(Group $group)
    {
        $this->groupRepository->add($group);
    }
}

然后我编写配置以将存储库注入(inject)该服务:

services:
#    service_name:
#        class: AppBundle\Directory\ClassName
#        arguments: ["@another_service_name", "plain_value", "%parameter_name%"]

    group_repository:
        class: AppBundle\Repository\GroupRepository
        factory: ["@doctrine.orm.entity_manager", getRepository]
        arguments:
          - AppBundle\Entity\Group

    group_user_repository:
        class: AppBundle\Repository\GroupUserRepository
        factory: ["@doctrine.orm.entity_manager", getRepository]
        arguments:
          - AppBundle\Entity\GroupUser

    group_user_service:
        class: AppBundle\Service\GroupUserService
        arguments: ["@group_repository", "@group_user_repository"]
        #arguments:
        #    - "@group_repository"

我得到错误:

Catchable Fatal Error: Argument 1 passed to AppBundle\Service\GroupUserService::__construct() must be an instance of AppBundle\Repository\GroupRepository, instance of Doctrine\ORM\EntityRepository given, called in E:\other\dropbox\Dropbox\programavimas\kodo pavyzdziai\htdocs\users_admin_demo\var\cache\dev\appDevDebugProjectContainer.php on line 1654 and defined

如果我通过了 GroupRepository，你能解释一下为什么它会得到 EntityRepository 实例吗？以及如何解决？我尝试搜索类似的问题，但几个小时后我没有看到结果。

更新:

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="AppBundle\Repository\GroupRepository")
 * Group
 */
class Group
{
    /**
     * @var string
     */
    private $name;

    /**
     * @var integer
     */
    private $id;


    /**
     * Set name
     *
     * @param string $name
     *
     * @return Group
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

    /**
     * Get name
     *
     * @return string
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }
}

Answer 1

定义 App Bundle\Repository\Group Repository 作为 AppBundle\Entity\Group 的存储库

@ORM\Entity(repositoryClass="AppBundle\Repository\GroupRepository")

XML

<entity
    name="AppBundle\Entity\Group"
    repository-class="AppBundle\Repository\GroupRepository">
</entity>
