Symfony2 生产环境:由于在链配置中找不到自定义用户类而导致映射异常

Question

我正在开发一个有点复杂的基于Symfony2.1的应用程序，可以连接到两个不同的数据库（有两个实体管理器，一个连接到Oracle，另一个连接到PostgreSQL）和一个自定义用户类（带有自定义密码编码器）。

我已经设法让它在开发环境中正确运行，但是每当我尝试在生产环境中运行它时，我都会收到下一个错误：

Doctrine\Common\Persistence\Mapping\MappingException：在链配置的命名空间中找不到类'MyFirm\UserManagerBundle\Entity\User'（未捕获的异常）

我在app/config/security.yml中的安全性和编码器：

security:
  encoders:
    MyFirmUserManagerBundleEntityUser:
        id: myfirm_usermanager.password_encoder
  providers:
    user_db:
        entity: 
            class: MyFirmUserManagerBundleEntityUser
            property: username 

app/config/config.yml 中的 doctrine.orm 部分：

doctrine:
  orm:
    auto_generate_proxy_classes: %kernel.debug%
    default_entity_manager: user_config_db 
    entity_managers:
        event_db:
            connection:   event_db
            mappings:
                MyFirmEventManagerBundle: ~
        user_config_db:
            connection:   user_config_db
            mappings:
                MyFirmUserManagerBundle:  ~

最后，这是最终的异常日志：

有人知道吗？多谢。

Answer 1

问题似乎是Symfony2中的一个错误：如果您希望默认实体管理器在生产环境中作为默认实体管理器工作，则必须将默认实体管理器命名为"default"。

将 app/config/config.yml 中的 doctrine.orm 部分更改为：

doctrine:
  orm:
    auto_generate_proxy_classes: %kernel.debug%
    default_entity_manager: default
    entity_managers:
      event_db:
        connection:   event_db
        mappings:
            MyFirmEventManagerBundle: ~
      default:
        connection:   user_config_db
        mappings:
            MyFirmUserManagerBundle:  ~

一切正常。

好的。最后，经过很长时间，我找到了解决方案：您必须使用 manager_name 选项将实体管理器名称添加到安全定义中：

安全：  编码：    MyFirm\UserManagerBundle\Entity\User：        ID： myfirm_usermanager.password_encoder  供应商：    user_db：        实体：            类： MyFirm\UserManagerBundle\Entity\User            属性：用户名            manager_name：user_config_db
