使用帶有KnpGaufrette和學說VichUploader當我嘗試使用以下安裝在我的Symfony2項目：循環引用在Symfony2中

VichUploader Bundle用於處理文件上傳
KnpGaufrette Bundle應由VichUploader被用作存儲適配器

問題：當我嘗試使用Gaufrette存儲適配器「doctrine_dbal」我得到以下錯誤：

[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嘗試檢查配置，例如， on

app/console cache:clear

我該如何解決這個問題？

我的設置

我的項目設置是symfony/framework-standard-edition與2.5.*版本的默認設置，但不AcmeDemo捆綁。

我壓根兒通過作曲家添加軟件包：

composer require knplabs/knp-gaufrette-bundle vich/uploader-bundle

...將它們添加到AppKernel的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 
    ); 
//...

...並增加了以下配置config.yml，這是基於上的文檔VichUploader with Gaufrette和KnpGaufrette with Doctrine DBAL：

# ... 
knp_gaufrette: 
    stream_wrapper: ~ 

    adapters: 
     storage_adapter: 
      doctrine_dbal: 
       connection_name: default 
       table: data_storage 
       columns: 
        key: id 
        content: file 
        mtime: mtime 
        checksum: checksum 

    filesystems: 
     storage_fs: 
      adapter: storage_adapter 



vich_uploader: 
    db_driver: orm 
    storage: gaufrette 

    mappings: 
     storage: 
      uri_prefix:   /images/products 
      upload_destination: storage_fs

爲什麼doctrine.dbal.default_connection服務對vich_uploader.upload_handler依賴？我會以此開始。 –
