Symfony 3 JMSPaymentCoreBundle-类名必须是有效的对象或字符串

Question

我是Symfony的新手，我正在尝试实现用于处理付款JMSPaymentCoreBundle的捆绑软件。我遵循了指南：http://jmspaymentcorebundle.readthedocs.io/en/stable/guides/accepting_payments.html

但是当我创建服务“ payment.plugin_controller”时，插件控制器出现异常（类名必须是有效的对象或字符串）

我遵循了所有步骤，但不知道可能出什么问题。

我输入了代码，也许您能帮我一把！ ：D

订单类：

        if ($form->isSubmitted() && $form->isValid()) {

            $ppc->createPaymentInstruction($instruction = $form->getData());

        $pendingTranstaction = $instruction->getPendingTransaction();

        if($pendingTranstaction !== null) {
            return $pendingTranstaction->getPayment();
        }
        $ppc = $this->get('payment.plugin_controller');
        $amount = $instruction->getAmount() - $instruction->getDepositedAmount();

    }

    /**

        throw new Exception("0");
    }


    /**

    public function paymentCompleteAction(Orders $order)
    {
        return new Response('Payment complete');
    }

    /**
     * @Route("/cancel", name = "payment_cancel")
     */
    public function CancelAction( )
    {
        $this->get('session')->getFlashBag()->add('info', 'Transaction annulée.');
        return new Response('Payment fail');
    }
}

服务：

services:
  payment.plugin_controller:
    class: JMS\Payment\CoreBundle\PluginController\EntityPluginController
    arguments:
       EntityManager: "@doctrine.orm.entity_manager"

套装

public function registerBundles()
    {
        $bundles = [
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new AppBundle\AppBundle(),
            new JMS\Payment\CoreBundle\JMSPaymentCoreBundle(),
            new JMS\Payment\PaypalBundle\JMSPaymentPaypalBundle(),
            new JMS\DiExtraBundle\JMSDiExtraBundle(),
            new JMS\AopBundle\JMSAopBundle()
        ];

配置：

jms_payment_core:
    encryption:
      secret: xxx

jms_payment_paypal:
    username: xxx
    password: xxx
    signature: xxx-xxx
    debug: false

我必须创建一个服务，因为在指南中将调用依赖关系payment.plugin_controller（$ this-> get（'payment.plugin_controller'）。对吗？

非常感谢您的帮助！
