我使用symfony 2,我想用它来使用Memcache,但问题是我找不到任何Memcache的解释我刚刚找到memcached所以它们是相同的设置步骤吗？我添加了这些行来在symfony上安装Memcache？

config.yml

framework:
  session:
    handler_id: session.handler.memcached

for parameters.yml

parameters:   
  memcached_host: 127.0.0.1
  memcached_port: 11211
  memcached_prefix: custom_key_
  memcached_expire: 14400

services.yml

services:
  session.handler.memcached:
    class: Symfony\Component\HttpFoundation\Session\Storage\Handler\MemcachedSessionHandler
    arguments: [ "@session.memcached", { prefix: '%memcached_prefix%', expiretime: '%memcached_expire%' } ]


services:
  session.memcached:
    class: Memcached
    arguments:
      persistent_id: %memcached_prefix%
    calls:
      - [ addServer, [ %memcached_host%, %memcached_port% ]]



services:
  session.memcached:
    class: Madisoft\AppBundle\Utils\MemcachedWrapper
    arguments:
      persistent_id: '%memcached_prefix%'
    calls:
      - [ addServer, [ '%memcached_host%', '%memcached_port%' ] ]

当我尝试使用此命令在xampp上安装memcache时

wget http://pecl.php.net/get/memcache-3.0.8.tgz

tar xf memcache-3.0.8.tgz

cd memcache-3.0.8

/opt/lampp/bin/phpize


./configure --enable-memcache --with-php-config=/opt/lampp/bin/php-config


make && make install


/opt/lampp/lampp restart

这条线后我得到错误

make && make install

完整的错误消息

当我在终端上运行此命令时

php app/console doctrine:schema:validate

我收到这个错误

  The autoloader expected class "tuto\testBundle\Entity\product" to be defined in file "../src/tuto/testBundle/Entity/product.php". The file was found but the class was not in it, the class name or names  
  pace probably has a typo.                                                                                 

我使用symfony 2.8和我的代码就像示例页面那么有什么不对？

product.php文件代码

<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;


/**
 * @ORM\Entity
 * @ORM\Table(name="product")
 */
class product 
{


  /** 
  *@ORM\Column(type="integer")
  *@ORM\Id
  *@ORM\GeneratedValue(strategy="AUTO")  
  */


  private $id;
  /** @ORM\Column(length=140) */




  public function getUserId(){
    return $this->UserId;
  }
  public function setUserId($id){
    return $this->UserId=$id;
  }
}

和product.orm.yml文件 …
