身份验证/登录中的凭据错误 - Symfony2

我是symfony2和doctrine的新手.我正在尝试基于文档和一些教程的身份验证系统.我不知道为什么我这么难找到它.

这是我基于2个单独的教程做的.

我的用户实体:

isActive = true;
        $this->salt = md5(uniqid(null, true));
    }

    /**
     * @inheritDoc
     */
    public function getUsername()
    {
        return $this->username;
    }

    /**
     * @inheritDoc
     */
    public function getSalt()
    {
        return $this->salt;
    }

    /**
     * @inheritDoc
     */
    public function getPassword()
    {
        return $this->password;
    }

    /**
     * @inheritDoc
     */
    public function getRoles()
    {
        return array('ROLE_USER');
    }

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

    /**
     * @see \Serializable::serialize()
     */
    public function serialize()
    {
        return serialize(array(
            $this->id,
            $this->username,
            $this->salt,
            $this->password,
        ));
    }

    /**
     * @see \Serializable::unserialize()
     */
    public function unserialize($serialized)
    {
        list (
            $this->id,
            $this->username,
            $this->salt,
            $this->password,
        ) = unserialize($serialized);
    }

    /**
     * Get id
     *
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set username
     *
     * @param string $username
     * @return User
     */
    public function setUsername($username)
    {
        $this->username = $username;

        return $this;
    }

    /**
     * Set salt
     *
     * @param string $salt
     * @return User
     */
    public function setSalt($salt)
    {
        $this->salt = $salt;

        return $this;
    }

    /**
     * Set password
     *
     * @param string $password
     * @return User
     */
    public function setPassword($password)
    {
        $this->password = $password;

        return $this;
    }

    /**
     * Set email
     *
     * @param string $email
     * @return User
     */
    public function setEmail($email)
    {
        $this->email = $email;

        return $this;
    }

    /**
     * Get email
     *
     * @return string 
     */
    public function getEmail()
    {
        return $this->email;
    }

    /**
     * Set isActive
     *
     * @param boolean $isActive
     * @return User
     */
    public function setIsActive($isActive)
    {
        $this->isActive = $isActive;

        return $this;
    }

    /**
     * Get isActive
     *
     * @return boolean 
     */
    public function getIsActive()
    {
        return $this->isActive;
    }
}

我的security.yml

# app/config/security.yml
security:
    encoders:
        Login\LoginBundle\Entity\User:
            algorithm:        sha512
            encode_as_base64: true
            iterations:       1

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

    providers:
        administrators:
            entity: { class: LoginLoginBundle:User, property: username }

    firewalls:
        admin_area:
            pattern: ^/
            anonymous: ~
            form_login:
                login_path: login
                check_path: login_check
            logout:
                path:   /logout
                target: /login

    access_control:
        - { path: ^/admin, roles: ROLE_ADMIN }

我的控制器

setUsername('aa');
          $user->setEmail('admin@umahanov.com');
          $user->setSalt(md5(time()));
          $user->setIsActive(false);

          $encoder = new MessageDigestPasswordEncoder('sha512',true,1);
          $password = $encoder->encodePassword('1234', $user->getSalt());
          $user->setPassword($password);
          $manager = $this->getDoctrine()->getManager();
          $manager->persist($user);

          $manager->flush();  

        return $this->render('LoginLoginBundle:Default:index.html.twig', array('name' => $name));
    }
}

所以想法是在/hello/me被叫时插入用户.并在admin/hello/me调用时执行登录.现在,在第一次迭代后,我的数据库包含此数据

1
d033e22ae348aeb5660fc2140aec35850c4da997
admin
admin@example.com
1

但是,当我提供aa并1234以登录形式作为凭证时,它显示*错误的凭据.我错过了什么？*是否有任何简单的教程来简单地使用symfony2描述整个身份验证.还有简单的密码.请帮助......请:(
