我尝试在Symfony2项目中使用以下设置：
问题：一旦我尝试使用Gaufrette存储适配器＆＃34; doctrine_dbal＆＃34;我收到以下错误：
[Symfony\Component\DependencyInjection\Exception\ServiceCircularReferenceException]
Circular reference detected for service "doctrine.dbal.default_connection", path: "doctrine.orm.default_entity_manager -> doctrine.dbal.default_connection -> vich_uploader.upload_handler -> vich_uploader.storage.gaufrette -> knp_gaufrette.filesystem_map -> gaufrette.storage_fs_filesystem".
一旦Symfony尝试检查配置，就会出现问题，例如在
app/console cache:clear
如何解决此问题？
我的项目设置是symfony/framework-standard-edition的默认设置，版本为2.5.*，没有AcmeDemo Bundle。
我只是通过Composer添加了Bundles：
composer require knplabs/knp-gaufrette-bundle vich/uploader-bundle
...将它们添加到AppKernel＆＃39; registerBundles()：
//...
$bundles = array(
new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
new Symfony\Bundle\SecurityBundle\SecurityBundle(),
new Symfony\Bundle\TwigBundle\TwigBundle(),
new Symfony\Bundle\MonologBundle\MonologBundle(),
new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
new Symfony\Bundle\AsseticBundle\AsseticBundle(),
new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
new AppBundle\AppBundle(),
new Vich\UploaderBundle\VichUploaderBundle(), //NEW
new Knp\Bundle\GaufretteBundle\KnpGaufretteBundle(), //NEW
);
//...
...并将以下配置添加到config.yml，该# ...
