Symfony - FOSUserBundle配置文件视图在更新到Symfony 2.8后不起作用

Question

我已经将Symfony项目从2.6版本升级到2.8版本，在此之后，当我请求纵断面图时，我收到错误500。错误是：

Error: Call to a member function has() on null

Stack Trace in vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Controller/Controller.php at line 350   -
 */
public function getUser()
{
    if (!$this->container->has('security.token_storage')) {
        throw new \LogicException('The SecurityBundle is not registered in your application.');
    }

当我运行composer show -i时，我看到下面的列表：

问题出在您的控制器上。可能它们扩展了Symfony\Component\ DependencyInjection\ContainerAware，后者从2.8版起就不推荐使用了。删除它并使用Symfony\ Component\DependencyInjection\ ContainerAwareTrait。

use Symfony\Component\DependencyInjection\ContainerAwareInterface; 
use Symfony\Component\DependencyInjection\ContainerAwareTrait;

class MyBundleController implements ContainerAwareInterface { 
    use ContainerAwareTrait; 
    /** 
    * @Route("/", name="_index") 
    * @Template() 
    */ 
    public function indexAction() { 
            var_dump($this->container); 
            return array(); 
    }
}

编辑: Cerad在评论中是正确的：

不需要重写从控制器扩展而来的现有控制器。问题出在像FOSUserBundle这样的第三方包中，这些包不能从控制器扩展。然而，即使它们仍然应该在2.8以下工作，或者至少给出不同的错误。

无论在哪种情况下，它都应该可以工作。
