使用AdvancedUserInterface的Symfony

我正在尝试用Symfony2实现一个登录系统。我正在为我的用户实体实现AdvancedUserInterface，并且在尝试登录时不断出现以下错误。感谢您的帮助

错误：

$user must be an instanceof UserInterface, an object implementing a __toString method, or a primitive string.

用户实体：

<?php

namespace Flc\UserBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\AdvancedUserInterface;
use Serializable;

/**
* User
*
* @ORM\Table(name="users")
* @ORM\Entity(repositoryClass="Flc\UserBundle\Entity\UserRepository")
*/
class User implements AdvancedUserInterface, Serializable {

/**
 * @var integer
 *
 * @ORM\Column(name="userId", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $userId;

/**
 * @var string
 *
 * @ORM\Column(name="userEmail", type="string", length=50)
 */
private $userEmail;

/**
 * @var string
 *
 * @ORM\Column(name="userName", type="string", length=20)
 */
private $userName;

/**
 * @var string
 *
 * @ORM\Column(name="userPassword", type="string", length=60)
 */
private $userPassword;

/**
 * @var string
 *
 * @ORM\Column(name="userSalt", type="string", length=60, nullable=true)
 */
private $userSalt;

/**
 * @var string
 *
 * @ORM\Column(name="userFirstName", type="string", length=40)
 */
private $userFirstName;

/**
 * @var string
 *
 * @ORM\Column(name="userLastName", type="string", length=40)
 */
private $userLastName;

/**
 * @var string
 *
 * @ORM\Column(name="userPhone", type="string", length=10)
 */
private $userPhone;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="created", type="datetime")
 */
private $created;

/**
 * @var boolean
 *
 * @ORM\Column(name="isActive", type="boolean")
 */
private $isActive;

/**
 * @var array
 *
 * @ORM\Column(name="roles", type="json_array", nullable=true)
 */
private $roles;

尝试在您的用户实体上添加_utoString方法：

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

---

在用户存储库中，您需要替换：

public function findOneByUsernameOrEmail($username) {
    return $this->createQueryBuilder('u')
                    ->andWhere('u.userName = :username OR u.userEmail = :email')
                    ->setParameter('username', $username)
                    ->setParameter('email', $username)
                    ->getQuery()
                    ->getOneOrNullResult();
}

public function loadUserByUsername($username) {
    //$user = $this->findOneByUsernameOrEmail($username);
    $user = $this->findOneBy(array("userName"=>$username));
    if (!$user) {
        throw new UsernameNotFoundException('No user found for ' . $username);
    }
    return $user;
}

与：

public function loadUserByUsername($username)
{
    $q = $this
        ->createQueryBuilder('u')
        ->where('u.username = :username OR u.email = :email')
        ->setParameter('username', $username)
        ->setParameter('email', $username)
        ->getQuery();

    try {
        $user = $q->getSingleResult();
    } catch (NoResultException $e) {
        throw new UsernameNotFoundException(sprintf('Unable to find an active admin AcmeUserBundle:User object identified by "%s".', $username), 0, $e);
    }

    return $user;
}

public function findOneByUsernameOrEmail($username) {
    return $this->createQueryBuilder('u')
                    ->andWhere('u.userName = :username OR u.userEmail = :email')
                    ->setParameter('username', $username)
                    ->setParameter('email', $username)
                    ->getQuery()
                    ->getOneOrNullResult();
}

public function loadUserByUsername($username) {
    //$user = $this->findOneByUsernameOrEmail($username);
    $user = $this->findOneBy(array("userName"=>$username));
    if (!$user) {
        throw new UsernameNotFoundException('No user found for ' . $username);
    }
    return $user;
}

public function loadUserByUsername($username)
{
    $q = $this
        ->createQueryBuilder('u')
        ->where('u.username = :username OR u.email = :email')
        ->setParameter('username', $username)
        ->setParameter('email', $username)
        ->getQuery();

    try {
        $user = $q->getSingleResult();

        throw new UsernameNotFoundException(sprintf('Unable to find an active admin AcmeUserBundle:User object identified by "%s".', $username), 0, $e);

    return $user;
