symfony2和抛出异常错误 [英] symfony2 and throwing exception error

问题描述

 使用Symfony\Component\HttpKernel\ Exception\HttpNotFoundException; 
使用Symfony\Component\Security\Core\Exception\AccessDeniedException; 
  

然后我以下列方式使用它们：

抛出新的HttpNotFoundException（找不到页面）;

  
 throw $ this-> createNotFoundException（'该产品不存在'）; 
  

但是我收到错误，如HttpNotFoundException没有找到。

这是抛出异常的最佳方法？

解决方案

尝试：

 使用Symfony\Component\HttpKernel\Exception\NotFoundHttpException; 
  

和

 抛出新的NotFoundHttpException（找不到页面）; 
  

我想你有点向后： - ）

I am trying to throw exceptions and I am doing the following:

use Symfony\Component\HttpKernel\Exception\HttpNotFoundException;
use Symfony\Component\Security\Core\Exception\AccessDeniedException;

I am then using them the following way:

 throw new HttpNotFoundException("Page not found");
   throw $this->createNotFoundException('The product does not exist');

however I am getting errors like HttpNotFoundException is not found etc.

Is this the best way to throw exceptions?

解决方案

Try:

use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

and

throw new NotFoundHttpException("Page not found");

I think you got it a bit backwards :-)
