Event Listeners in ZF2/Doctrine ORM

Application\Controller\IndexController.php

<?php

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;

class VillageController extends AbstractActionController
{
  private $em;

    public function indexAction()
    {
        $this->identity()->getVillage()->setName('blah');
        $this->getEntityManager()->flush();
    }

	public function getEntityManager()
    {
        if (!$this->em) {
            $this->em = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');
        }
        return $this->em;
    }

}

Application\Entity\Village.php

<?php

namespace Application\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Village
 *
 * @ORM\Table(name="villages")
 * @ORM\Entity
 * @ORM\EntityListeners({"Application\Listener\Village"})
 */
class Village
{
  // etc etc
}

Application\Listener\Village.php

<?php

namespace Application\Listener;

use Doctrine\ORM\Event\PreUpdateEventArgs;
use Application\Entity;

class Village
{

    public function preUpdate(Entity\Village $village, PreUpdateEventArgs $event)
    {
      var_dump($village);exit;
    }

}

super useful, thank you; but one question pops up, what is the most elegant way if i need to inject zf2 service manager into the village listener?
thx

check out this, it's SF2 altough problem is similiar:

I would create own entity listener resolver, extend the DefaultEntityListenerResolver. It would be better not to inject the service locator. It's a bad habit as ocramius said. It would be better then to inject the SM to the resolver, check if the listener is available through SM and create it that way.
