Symfony自动装配不会在指定路径中获取服务-Java 学习之路

尝试升级现有的Symfony 3.3.2项目以使用自动装配 .
按照此处的说明操作：https://symfony.com/doc/current/service_container/3.3-di-changes.html#content_wrapper .

对我不起作用的是能够将目录中的所有服务设置为公共 .

Important: 我的services.yml文件位于src / SiteBundle / Resources / config中，而不是app / config .

# src/SiteBundle/Resources/config/services.yml
services:
  _defaults: 
    autowire: true
    autoconfigure: true
    public: false

  SiteBundle\Service:
    resource: '../../Service'
    public: true

  CustomerOrderMasterRepository:
    class: Doctrine\ORM\EntityRepository
    factory: ["@doctrine.orm.entity_manager", get_repository]
    arguments:
      - SiteBundle\Entity\CustomerMaster

  SiteBundle\Service\CustomersService:
    arguments:
      - '@doctrine.orm.entity_manager'
      - '@CustomerMasterRepository'

如果我然后执行控制台调试：container | grep -i服务，它只显示输出头和Symfony服务容器 . src / SiteBundle / Service目录中的所有类都没有被选中 .

Symfony Container公共服务服务ID类名称service_container Symfony \ Component \ DependencyInjection \ ContainerInterface

如果我添加--show-private，那么它们会被显示（以及许多其他内容） .

Symfony Container公共和私有服务服务ID类名称1_bcf140bb848ef41617942628c8525b4872574e826d00fee6aaabbf2ede89fbb8 Symfony \ Component \ DependencyInjection \ ServiceLocator Psr \ Container \ ContainerInterface别名为“service_container”SiteBundle \ Service \ CustomerOrdersService SiteBundle \ Service \ CustomerOrdersService SiteBundle \ Service \ CustomersService SiteBundle \ Service \ CustomersService SiteBundle \ Service \ InventoryItemsService SiteBundle \ Service \ VendorOrsService SiteBundle \ Service \ VendorOrdersService SiteBundle \ Service \ VendorsService SiteBundle \ Service \ VendorsService SiteBundle \ Service \ WorkOrdersService SiteBundle \ Service \ WorkOrdersService Symfony \ Component \ DependencyInjection \ ContainerInterface“service_container”别名“argument_resolver.service Symfony \ Component \ HttpKernel \ Controller \ ArgumentResolver \ ServiceValueResolver routing.loader.service Symfony \ Component \ Routing \ Loader \ DependencyInjection \ ServiceRouterLoader secu rity.authentication.rememberme.services.abstract security.authentication.rememberme.services.persistent Symfony \ Component \ Security \ Http \ RememberMe \ PersistentTokenBasedRememberMeServices security.authentication.rememberme.services.simplehash Symfony \ Component \ Security \ Http \ RememberMe \ TokenBasedRememberMeServices service_container Symfony的\分量\ DependencyInjection \ ContainerInterface service_locator.1712c3a50d1ec2c742b2ead0f03bb76c的Symfony \分量\ DependencyInjection \服务定位service_locator.26ac001b3ede28481ac0de703666b4d7的Symfony \分量\ DependencyInjection \服务定位service_locator.39e66930232432ca5ba91e98fdd8a17b的Symfony \分量\ DependencyInjection \服务定位service_locator.6f24348b77840ec12a20c22a3f985cf7的Symfony \分量\ DependencyInjection \服务定位service_locator.8925f20c49cbd61fcb37adf8c595459e Symfony \ Component \ DependencyInjection \ ServiceLocator service_locator.b8d2046fb854cde05549fb309e1a80d2别名为“1_bcf140bb848ef41617942628c8525b4872574e82” 6d00fee6aaabbf2ede89fbb8“service_locator.ceb8bbb9f48e8bfd1c8ec2d209eabdca Symfony \ Component \ DependencyInjection \ ServiceLocator

如果我注释掉SiteBundle \ Service \ CustomerService定义，则debug：container命令会抛出此异常：

PHP致命错误：未捕获的Symfony \ Component \ DependencyInjection \ Exception \ AutowiringFailedException：无法自动装配服务“SiteBundle \ Entity \ CustomerMasterRepository”：方法“Doctrine \ ORM \ EntityRepository :: __ construct（）”的参数“$ em”必须具有类型-hint或明确给出一个值 . 坦率地说，我无法做出头脑或尾巴 .

建议？谢谢 .

这是主要问题：

PHP致命错误：未捕获的Symfony \ Component \ DependencyInjection \ Exception \ AutowiringFailedException：无法自动装配服务“SiteBundle \ Entity \ CustomerMasterRepository”：方法“Doctrine \ ORM \ EntityRepository :: __ construct（）”的参数“$ em”必须具有类型-hint或明确给出一个值 . 坦率地说，我无法做出头脑或尾巴 .

当您使用EntityRepository作为服务时，会发生这种情况，但是继承自Doctrine BaseRepository . 这种组合永远不会发生 .

The repository should use composition, to get to Doctrine 喜欢这个：
```
<?php

namespace AppBundle\EntityRepository;

use AppBundle\Entity\Channel;
use Doctrine\ORM\EntityManager;

class ChannelRepository
{
    private $repository;

    public function __construct(EntityManager $entityManager)
    {
        $this->repository = entityManager->getRepository(Channel::class);
    }

    public function getOneByName(string $name)
    {
        return $this->repository->findOneBy(['name' => $name]);
    }
}
```

要使自定义存储库工作，我必须覆盖 __construct 方法以提供 EntityManager 和 ClassMetadata ，如下所示：

应用程序/配置/ services.yml

services:
    _defaults:
        autowire: true
        autoconfigure: true
        public: false

    app.repository.channel:
        class: \AppBundle\EntityRepository\ChannelRepository

SRC /的appbundle / EntityRepository / ChannelRepository.php：

<?php

namespace AppBundle\EntityRepository;

use AppBundle\Entity\Channel;
use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Mapping\ClassMetadata;

class ChannelRepository extends RepositoryFactory
{
    public function __construct(EntityManager $entityManager)
    {
        parent::__construct($entityManager, new ClassMetadata(Channel::class));
    }

    public function getOneByName(string $name)
    {
        return $this->findOneBy(['name' => $name]);
    }
}

SRC /的appbundle /实体/ Channel.php

<?php

namespace AppBundle\Entity;

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Table(name="channel")
 * @ORM\Entity(repositoryClass="\AppBundle\EntityRepository\ChannelRepository")
 *
 */
class Channel
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

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