Symfony2 FormType依赖注入

我在Controller，Repository中使用了DI。所有存储库都使用BaseRepository进行扩展。但是，当使用FormType给出错误。错误消息：Symfony2 FormType依赖注入

ContextErrorException: Catchable Fatal Error: Argument 2 passed to Personal\SiteBundle\Repository\BaseRepository::__construct() must be an instance of Memcache, instance of Doctrine\ORM\Mapping\ClassMetadata given, called in /home/personal/www/vendor/doctrine/orm/lib/Doctrine/ORM/Repository/DefaultRepositoryFactory.php on line 75 and defined in /home/personal/www/src/Personal/SiteBundle/Repository/BaseRepository.php line 22

我该怎么想？结构如下

AdminBundle/services.yml

personaladmin.towncontroller:

    arguments: 
     entityManager: "@doctrine.orm.entity_manager"

你在service.yml定义的“personalsite.baserepository” beeing构建时总是需要“@memcache”服务为第二个参数，你显然在某些时候缺少 – jahller

@jahller对不起，我加BaseRepository.php –

错误消息是因为Doctrine 2试图获得常规的Doctrine Repository。你的BaseRepository不会扩展我认为是设计的DoctrineRepository？如果是这样，则从您的实体中移除存储库类名，以便Doctrine不会尝试使用它们。但我怀疑你确实希望BaseRepository扩展DoctrineRepository。如果是这样，我可以告诉你需要为你的services.yml – Cerad

所以你的BaseRepository需要扩展DoctrineReposotory。 Doctrine使用工厂getRepository方法创建存储库。有没有简单的方法来哄它传递memcache。相反，我们需要使用setter注入。

use Doctrine\ORM\EntityRepository; 
class BaseRepository extends EntityRepository 
{ 
    // No constructor needed 

    // Setter injection 
    setMemcachedProvider(Memcache $memcachedProvider) 
    { 
     $this->_memcacheProvider = $memcachedProvider; 
    }

在你services.yml文件摆脱BaseRepository服务，然后编辑你的资料库服务：

personalsite.cityrepository: 
    class: Personal\SiteBundle\Repository\CityRepository 
    factory_service: 'doctrine.orm.default_entity_manager' 
    factory_method: 'getRepository' 
    arguments: 
     - 'Personal\SiteBundle\Entity\City' 
    calls: 
     - [setMemcachedProvider, ['@memcache']]

这应该做的伎俩。

我对你为什么注入memcache有点好奇。我假设你有一些使用它的自定义存储库代码？教义会忽略它。如果您尝试配置Doctrine以使用memcache，那么这完全是一个不同的过程。
