Question

我正在开发一个复杂的基于Symfony2.1的应用程序，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常运行，但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）

app / config / security.yml中的安全和编码器：

security:
  encoders:
    MyFirm\UserManagerBundle\Entity\User:
        id: myfirm_usermanager.password_encoder

  providers:
    user_db:
        entity: 
            class: MyFirm\UserManagerBundle\Entity\User
            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：

有人有任何线索吗？非常感谢。

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，则必须将其命名为“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。

行。最后，经过太多时间后，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性定义中：

security:
  encoders:
    MyFirm\UserManagerBundle\Entity\User:
        id: myfirm_usermanager.password_encoder

  providers:
    user_db:
        entity: 
            class: MyFirm\UserManagerBundle\Entity\User
            property: username 
            manager_name: user_config_db
