【问题描述】：

我的 Symfony2 控制器中出现异常问题...我正在尝试捕获 NotFoundHttpException，但是 catch 块...只是没有发生，它进入标准 Symfony2 异常使用堆栈跟踪的页面，而不是在开发环境中...

我有以下代码：

<?php

namespace SeerUK\DWright\GalleryBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;

use SeerUK\DWright\GalleryBundle\Entity\Gallery;


class GalleryController extends Controller
{
    public function indexAction($galleryId)
    {
        try
        {
            $gallery = $this->getDoctrine()
                ->getRepository('SeerUKDWrightGalleryBundle:Gallery')
                ->find($galleryId);

            throw $this->createNotFoundException('rawr'); // Just for the sake of testing...

            if (!$gallery) {
                throw $this->createNotFoundException(
                    'No gallery found for id ' . $galleryId
                );
            }

            $galleryId          = $gallery->getId();
            $galleryName        = $gallery->getName();
            $galleryDesc        = $gallery->getDesc();
            $galleryPublishedOn = $gallery->getPublishedOn();

            return $this->render('SeerUKDWrightGalleryBundle:Gallery:index.html.twig', array(
                'galleryId'          => $galleryId,
                'galleryName'        => $galleryName,
                'galleryDesc'        => $galleryDesc,
                'galleryPublishedOn' => $galleryPublishedOn->format('Y-m-d H:i:s'),
            ));
        }
        catch (Symfony\Component\HttpKernel\Exception\NotFoundHttpException $e)
        {
            echo $e->message;
        }
    }
}

【解决方案1】：

你应该试试 catch (\Symfony\Component\HttpKernel\Exception\NotFoundHttpException $e) 或者只使用这个 NotFoundHttpException...

可能它想在你的情况下捕捉SeerUK\DWright\GalleryBundle\Controller\Symfony\Component\HttpKernel\Exception\NotFoundHttpException :)

您先生，您说得对！它只需要在 Symfony2 异常名称之前的 `` :)
