mongodb - Symfony3 + "Authentication request could not be processed due to a system"

Question

我将 Symfony3 与 MongoDB ODM 结合使用。当我尝试登录时，出现以下消息:“由于系统问题，无法处理身份验证请求。”

这是 security.yml 文件:

# To get started with security, check out the documentation:
# http://symfony.com/doc/current/security.html
security:
    encoders:
        PlannerBundle\Document\Account: sha512

    providers:
        account_provider:
            mongodb: { class: PlannerBundle\Document\Account, property: username }
        in_memory:
            memory: ~

    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER
        ROLE_COMMERCIAL:  ROLE_USER
        ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN]

    firewalls:
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false

        admin:
            pattern: ^/admin
            form_login:
                provider: account_provider
                check_path: login
                login_path: login
                default_target_path: sonata_admin_dashboard

            logout:
                path:   logout
                target: /admin/login

            anonymous:    true
            logout: true

    access_control:
        - { path: ^/admin/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/admin, roles: [ROLE_ADMIN, ROLE_COMMERCIAL] }

实体文件:

    }

    public function eraseCredentials()
    {
    }

    }

    /** @see \Serializable::unserialize() */
    public function unserialize($serialized)
    {
        list (

    }

     */
    public function getId()

    }



}

你知道为什么吗？

谢谢你的帮助!

此错误消息过于笼统，您需要查看/logs/dev.log 以找到您的具体问题。搜索错误文本，例如在我的情况下它显示 "[Semantical Error] line 0, col 44 near 'username = :username': Error: 'username' is not defined." 然后我不得不在 security.yml 中添加这个 **"property: username"** 下面这个例子的最后一行:

    encoders:
        AppBundle\Entity\User:
