您好，我有一个Entity用户，我想像这样实现UserInterface和ObjectManagerAware：

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Persistence\ObjectManagerAware;
use Doctrine\Common\Persistence\ObjectManager;
use Doctrine\Common\Persistence\Mapping\ClassMetadata;

use Symfony\Component\Security\Core\User\UserInterface;

    }

    public function injectObjectManager(ObjectManager $objectManager, ClassMetadata $classMetadata)
    {
        $this->em = $objectManager;
    }
}

我需要ObjectManagerAware在此实体中添加自定义查询功能。

但是我有错误：

HTTP 500 Internal Server Error
Serialization of 'Closure' is not allowed

我仅在登录用户访问时出现错误，但是如果我注销，则网站不会出现错误

为什么会出现错误，以及如何解决？

Symfony似乎尝试将整个User对象序列化到会话中，并且某些字段不可序列化。您应该实现\serializable接口，并仅将重要字段添加到serialize方法。

class User implements UserInterface, ObjectManagerAware, \Serializable 

{
  ...
public function serialize()
{
    return serialize(array(
        $this->id,
        $this->username,
        $this->password
    ));
}


public function unserialize($serialized)
{
    list (
        $this->id,
        $this->username,
        $this->password
    ) = unserialize($serialized, array('allowed_classes' => false));
}
