在symfony2中製作通用的應用程序庫類嗎？

Question

我在symfony2中使用newby。我要讓常見的應用程序庫類的所有應用程序 使用我在管理\ FeatureBundle \庫\目錄下創建新文件AppUtils.php與定義

<?php 
namespace Admin\FeatureBundle\AppUtils; 
use Doctrine\ORM\EntityRepository; 
class AppUtils { 
... 

但在控制器

use Admin\FeatureBundle\Repository\AppUtils; 

class FeatureController extends Controller 
{ 

    public function editAction($id) 
    { 
     $em = $this->getDoctrine()->getManager(); 

     $entity = $em->getRepository('AdminFeatureBundle:Feature')->find($id); 

     if (!$entity) { 
      throw $this->createNotFoundException('Unable to find Feature entity.'); 
     } 

     $editForm = $this->createForm(new FeatureType(), $entity); 
     $deleteForm = $this->createDeleteForm($id); 
     $data= AppUtils::AddSystemParameters($data, $this, true); 
     echo '<pre>$data::'.print_r($data, true).'</pre><br>'; 
... 

我得到錯誤：

The autoloader expected class "Admin\FeatureBundle\Repository\AppUtils" to be defined in file "/mnt/diskC_XP/wamp5/www/wavendon-tenants/src//Admin/FeatureBundle/Repository/AppUtils.php". The file was found but the class was not in it, the class name or namespace probably has a typo. 

如何解決？如果有更好的方法來製作通用的應用程序庫類？

你有一個錯字

<?php 
namespace Admin\FeatureBundle\Repository; 

use Doctrine\ORM\EntityRepository; 
class AppUtils {
