我已将我的Symfony项目从2.6升级到2.8，之后，当我请求配置文件视图时，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，我会看到下一个列表：

问题出在您的控制器中。可能它们扩展了自2.8版以来不推荐使用的Symfony \ Component \ DependencyInjection \ ContainerAware。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();
}
}
