试图在 class 上调用方法 "getDoctrine" (Symfony)

Question

我正在尝试创建小型应用程序以使用 symfony/doctrine 通过 ID 从 table 中读取记录。我的步数：

已创建控制器 (GS\OrderBunndle\Controller\CustomerCuntroller.php), 路线。测试 URL - 正在运行；
为客户创建实体table (GS\OrderBundle\Entity\Customer.php) 列和 getters/setters;

3) 已创建 GS\OrderBundle\Entity\CustomerRepository.php（我不确定为什么需要它，它是自动生成的）。源代码：

namespace GS\OrderBundle\Entity;

use Doctrine\ORM\EntityRepository;

class CustomerRepository extends EntityRepository
{
}

4) 修改 CustomerController.php:

<?php

namespace GS\OrderBundle\Controller;
use Symfony\Component\HttpFoundation\Response;
use GS\OrderBundle\Entity\Customer;
use Doctrine\ORM\EntityManager; 

class CustomerController 
{

    public function indexAction($id)
    {
            $customer = $this->getDoctrine()->getRepository('GSOrderBundle:Customer')->find($id);
               return new Response(
            '<html><body>Number: '.$id.'</body></html>'
        );
    }
}

并出现以下错误：

Attempted to call method "getDoctrine" on class "GS\OrderBundle\Controller\CustomerController".

500 Internal Server Error - UndefinedMethodException

您需要扩展 Symfony 的 Controller class 才能使用 getDoctrine() 方法。

所以：

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class CustomerController extends Controller
{

    public function indexAction($id)
    {
            $customer = $this->getDoctrine()->getRepository('GSOrderBundle:Customer')->find($id);
               return new Response(
            '<html><body>Number: '.$id.'</body></html>'
        );
    }
}

（您也可以 define controller as a service 但这是更复杂的解决方案）
