Symfony2已登录，但未在探查器中进行身份验证

我正在Symfony 2.6上制作一个身份验证系统。注册过程有效。当我尝试登录时，我已经登录，并且我有"ROLE_USER"，但探查器说我没有经过身份验证。我不明白发生了什么。这是用户实体：

<?php
namespace AppBundle'Entity;
use Doctrine'ORM'Mapping as ORM;
use Symfony'Component'Validator'Constraints as Assert;
use Symfony'Bridge'Doctrine'Validator'Constraints'UniqueEntity;
use Symfony'Component'Security'Core'User'UserInterface;
/**

* @ORM'Table(name="baseuser")
* @ORM'Entity(repositoryClass="AppBundle'Repository'UserRepository")
* @UniqueEntity("email", message="error.user.email.taken")
*/
class User implements UserInterface, 'Serializable
{
/**
 * @var integer
 *
 * @ORM'Column(name="id", type="integer")
 * @ORM'Id
 * @ORM'GeneratedValue(strategy="AUTO")
 */
private $id;
/**
 * @var string
 *
 * @ORM'Column(name="email", type="string", length=255, unique=true)
 */
private $email;
/**
 * @var string

private $username;

private $password;
/**

private $salt;
/**

private $birthdate;
/**

private $roles;
/**

 */
private $createdAt;
/**

 *
 * @ORM'Column(name="updated_at", type="datetime")
 */
private $updatedAt;
public function __construct()
{
    $datetime = new 'DateTime();
    $this->createdAt = $datetime;
    $this->updatedAt = $datetime;
    $this->token     = base_convert(time(), 10, 36).'AppBundle'Library'StringHelper::randomString(5, "lower");
    $this->salt      = 'AppBundle'Library'StringHelper::randomString();
    $this->isActive  = true;
    $this->roles     = 1;
}
/**

 */
public function eraseCredentials()
{
}
/**

*
*/
public function getRoles() {
    switch ($this->roles) {
        case 1:
            $role =  'ROLE_USER';
            break;
        case 2:
            $role =  'ROLE_ADMIN';
            break;
        case 3:
            $role =  'ROLE_SUPER_ADMIN';
            break;
        default:
            $role = 'ROLE_USER';
            break;
    }
    return array($role);
}
/**
* Set the roles
*
* @param $roles
*/
public function setRoles($roles) {
    $this->roles = $roles;
    return $this;
}
/**
 * @see 'Serializable::serialize()
 */
public function serialize()
{
    return serialize(array(
        $this->id,
        $this->email,
        $this->password
    ));
}
/**
 * @see 'Serializable::unserialize()
 */
public function unserialize($serialized)
{
    list (
        $this->id,
        $this->email,
        $this->password,
    ) = unserialize($serialized);
}
}

这是我的安全。yml:

security:
    encoders:
         AppBundle'Entity'User:
            algorithm: bcrypt
            cost:      15
    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER
        ROLE_SUPER_ADMIN: [ ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH ]
    providers:
        administrators:
            entity: { class: AppBundle:User, property: email }
    firewalls:
        main:
            pattern:    ^/
            anonymous: ~
            form_login: ~
            logout: ~
    access_control:
        - { path: ^/admin, roles: ROLE_ADMIN }

我不知道问题出在哪里，知道吗？
