Symfony 2必须实现UserProviderInterface [英] Symfony 2 Must Implement UserProviderInterface

问题描述

在尝试使用symfony登录功能时，出现此错误必须实现UserProviderInterface
。我引用的是存储库* @ ORM\Entity（repositoryClass = Login\LogBundle\Entity\Repository\UserRepository）。有没有人有任何想法。

I get this error 'Must implement UserProviderInterface' when trying to using the symfony login features. I'm referencing the repository * @ORM\Entity(repositoryClass="Login\LogBundle\Entity\Repository\UserRepository") . Does anyone have any ideas.

存储库

      // src/Acme/UserBundle/Entity/UserRepository.php

   use Symfony\Component\Security\Core\User\UserInterface;
   use Symfony\Component\Security\Core\User\UserProviderInterface;
   use Symfony\Component\Security\Core\Exception\UsernameNotFoundException;

推荐答案

检查app / config / security.yml文件，如下所示：

Check the app/config/security.yml file with something like this:

# app/config/security.yml
security:
    providers:
        main:
            entity:
                class: Acme\UserBundle\Entity\User
                property: username

到repositoryClass UserRepository 的路径是错误的，也许你的意思是：

And path to repositoryClass UserRepository is wrong, maybe you mean this:

@ORM\Entity(repositoryClass="Login\LogBundle\Entity\UserRepository")

因为使用命名空间 \Login\LogBundle\Entity\UserRepository 。
