Php Symfony 2.2在登录后始终发送给我登录页面

我在Symfony 2.2.1上有一个简单的登录系统，问题是何时进入安全区域是显示登录表单并输入用户和通行证，但始终要将我发送到

/login

页面，有时将我发送到

/

。通过查看日志，我得到以下信息

正如您所看到的，当在SecurityContext中写入时，用户是空的，但我不知道原因

课程和设置 两个实体

Usuario

（用户）和

Rol

（角色）都实现了与symfony安全性对话的接口

routing.yml

设置

login:
    pattern: /admin/login
    defaults: { _controller: MySecurityBundle:Security:login }

login_check:
    pattern: /admin/login_check

logout:
    pattern: /admin/logout

这是我的

security.yml

设置

security:
    encoders:
        MyVendor\MySecurityBundle\Entity\Usuario:
            algorithm: sha256
            encode-as-base64: true

            logout:
                path:   /logout
                target: /

更新 我发现问题是我在方法

getUsername

i change to中没有返回任何内容

public function getUsername()
{
    return $this->getNombre();
}

但仍然是发送给我的登录页面

更新2 我在UserProvider类中发现了上一个问题，方法

refreshUser

错误，我改为

public function refreshUser(UserInterface $usuario)
{
    return $this->loadUserByUsername($usuario->getUsername());
}

这种方法很有效

public function refreshUser(UserInterface $usuario)
{
    return $this->loadUserByUsername($usuario->getUsername());
}
