Symfony Doctrine PrePersist/PreUpdate 不工作

Question

我在 symfony 中的生命周期回调有一些问题。这是我的实体：

<?php

namespace MainBundle\Bundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use FOS\UserBundle\Model\User as BaseUser;
use AppBundle\Entity\Event;
use Doctrine\Common\Collections\ArrayCollection;

/**
 * User
 *
 * @ORM\Table("users")
 * @ORM\Entity(repositoryClass="MainBundle\Bundle\Repository\UserRepository")
 * @ORM\HasLifecycleCallbacks()
 */
class User extends BaseUser
{

    public function __construct() {
        $this->events = new ArrayCollection();
        parent::__construct();
    }

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

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

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

    /**
     * events
     *
     * @var ArrayCollection
     * @access private
     * @ORM\OneToMany(targetEntity="AppBundle\Entity\Event",mappedBy="user")
     */
    private $events;


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

    /**
     * Set joined
     *
     * @param \DateTime $joined
     * @return User
     */
    public function setJoined($joined)
    {
        $this->joined = $joined;

        return $this;
    }

    /**
     * Get joined
     *
     * @return \DateTime 
     */
    public function getJoined()
    {
        return $this->joined;
    }

    /**
     * Set updated
     *
     * @param \DateTime $updated
     * @return User
     */
    public function setUpdated($updated)
    {
        $this->updated = $updated;

        return $this;
    }

    /**
     * Get updated
     *
     * @return \DateTime 
     */
    public function getUpdated()
    {
        return $this->updated;
    }

    /**
     * Set events
     *
     * @param \DateTime $events
     * @return User
     */
    public function setEvents($events)
    {
        $this->events = $events;

        return $this;
    }

    /**
     * Get events
     *
     * @return ArrayCollection 
     */
    public function getEvents()
    {
        return $this->events;
    }

    /**
     * Add event
     *
     * @param Event $event
     * @return User
     */
    public function addEvent(Event $event)
    {
        $this->events->add($event);

        return $this;
    }

    /**
     * Remove event
     *
     * @param Event $event
     * @return User
     */
    public function removeEvent(Event $event)
    {
        $this->events->removeElement($event);

        return $this;
    }

    /*
     * @ORM/PrePersist
     */
    public function PrePersist()
    {
        $this->joined = new \DateTime();
    }

    /*
     * @ORM/PreUpdate
     */
    public function PreUpdate()
    {
        $this->updated = new \DateTime();
    }
}

我已经搜索了一段时间，仍然没有发现问题。我已经尝试了这里的一些变化，例如用区分大小写的规则进行实验（我的意思是在这两种方法周围使用大写/小写）并且我尝试用双星/**开始块引号（至于这个我仍然不知道它是否有效或不是）。如果这里需要更多文件，我会粘贴它们。

您似乎有一些拼写错误。而不是：

 @ORM/PrePersist

尝试：

 @ORM\PrePersist

例如：

/**
 * @ORM\PrePersist
 */
public function PrePersist()
{
    $this->joined = new \DateTime();
}

/**
 * @ORM\PreUpdate
 */
public function PreUpdate()
{
    $this->updated = new \DateTime();
}

很惊讶这并没有引发异常，但是你去。希望这可以帮助！ :)
