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);
    }
}

我编写了配置以将存储库注入该服务：

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"

我收到错误：

捕获致命错误：传递给AppBundle \ Service \ GroupUserService :: __ construct（）的参数1必须是AppBundle \ Repository \ GroupRepository的实例，Doctrine \ ORM \ EntityRepository的实例，在E：\ other \ dropbox \中调用第1654行的Dropbox \ programavimas \ kodo pavyzdziai \ htdocs \ users_admin_demo \ var \ cache \ dev \ appDevDebugProjectContainer.php已定义

如果我通过GroupRepository，你能解释为什么它会获得EntityRepository inststance吗？以及如何解决它？我尝试搜索类似的问题，但几个小时后我看不到结果。

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;
    }
}

Group.orm.xml：

<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">

      <unique-constraint name="UNIQ_6DC044C55E237E06" columns="name"/>
    </unique-constraints>
    <id name="id" type="integer" column="id">

    <field name="name" type="string" column="name" length="255" nullable="false">
      <options>
        <option name="fixed"/>
      </options>
    </field>
  </entity>
</doctrine-mapping>

使用

将AppBundle\Repository\GroupRepository定义为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>

symfony 3传递给[some service]的参数1 :: __ construct（）必须是Doctrine \ ORM \ EntityRepository的[something]实例的实例
