Symfony2自定義樹枝擴展 - 未找到類

Question

我在添加樹枝擴展時遇到問題。我收到以下錯誤：

ClassNotFoundException in appDevDebugProjectContainer.php line 317: 
Attempted to load class "AppExtension" from namespace "HouseBundle\Twig". 
Did you forget a "use" statement for another namespace? 

我的代碼：

/Users/Sites/www/houses/src/housesBundle/Twig/AppExtension.php

<?php 

namespace HouseBundle\Twig; 

class AppExtension extends \Twig_Extension 
{ 

    public function getFilters() 
    { 
     return array(new \Twig_SimpleFilter('price', array($this, 'priceFilter')), 
    ); 


    public function priceFilter($number, $decimals = 0, $decPoint = '.', $thousandsSep = ',') 
    { 
     $price = number_format($number, $decimals, $decPoint, $thousandsSep); 
     $price = '$'.$price; 

     return $price; 
    } 

    public function getName() 
    { 
     return 'app_extension'; 
    } 
} 

/用戶/網站/ WWW /房屋/應用/配置/ services.yml

services: 
    app.twig_extension: 
     class: HouseBundle\Twig\AppExtension 
     tags: 
      - { name: twig.extension } 

任何幫助將非常感激。

鑑於這一文件路徑：

/用戶/網站/網絡/ anildave /房/ src目錄/ housesBundle /Twig/AppExtension.php

您使用了錯誤的命名空間

namespace HouseBundle\Twig; 

應該是

namespace housesBundle\Twig 

和

class: HouseBundle\Twig\AppExtension 

應該

class: housesBundle\Twig\AppExtension
