php - 在 Symfony2 中将 VichUploader 与 KnpGaufrette 和 Doctrine 一起使用时的循环引用

Question

我尝试在我的 Symfony2 项目中使用以下设置:

• VichUploader Bundle用于处理文件上传
• KnpGaufrette Bundle VichUploader 应该将其用作存储适配器

问题:当我尝试使用 Gaufrette 存储适配器“doctrine_dbal”时，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，问题就会出现，例如在

app/console cache:clear

我该如何解决这个问题？

我的设置

我的项目设置是 symfony/framework-standard-edition 的默认设置，版本 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 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
    );
//...

... 并在 config.yml 中添加了以下配置，该配置基于文档 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
