将此别名方法添加到控制器修复问题：

  public function getDoctrine（）
 {
 return $ this-> container-> get（'doctrine'）; 
} 
 

When I override FOSUserBundle's ProfileController and add these lines:

  $em = $this->getDoctrine()->getManager();
  $resultat = $em->getRepository('PublishDemandsBundle:Demands')->findAll();

I get the following error:

Call to undefined method Register\UserBundle\Controller\ProfileController::getDoctrine() in ProfileController.php.

Adding this alias-method to the controller fixed the issue:

public function getDoctrine()
{
    return $this->container->get('doctrine');
}
