如何在Symfony 2服务容器中设置Doctrine MongoDB存储库

Question

How do I correctly set up the service container in my Symfony 2 application to support custom Document repositories?

What I have so far is:

services:
  acme.repository_user:
    class: Acme\Repository\UserRepository
    arguments: [@doctrine.odm.mongodb.document_manager]

However, when I look at the constructor of the DocumentRepository class, of which my UserRepository inherits, I can see the following arguments:

public function __construct(DocumentManager $dm, UnitOfWork $uow, Mapping\ClassMetadata $class)

I seem to have injected the document manager but how do I inject the Unit of Work and the class meta data?

Try to define service as(sorry for xml):

<service id="acme.repository_user"
             class="Acme\Repository\UserRepository"
             factory-service="doctrine.odm.mongodb.document_manager"
             factory-method="getRepository"
             public="false">
    <argument>AcmeBundle:User</argument>
</service>
