Question

我正在构建“上次登录”功能。在创建activitylistener并将侦听器定义为服务之后，我收到错误

ContextErrorException：Catchable Fatal Error：传递给Acme \ SecurityBundle \ EventListener \ ActivityListener :: __ construct（）的参数2必须是Doctrine \ ORM \ EntityManager的实例，Doctrine \ Bundle \ DoctrineBundle \ Registry的实例，在C中调用：第350行的\ xampp \ htdocs \ sinfoc \ public \ app \ cache \ dev \ appDevDebugProjectContainer.php，在C：\ xampp \ htdocs \ sinfoc \ public \ src \ Acme \ SecurityBundle \ EventListener \ ActivityListener.php第22行中定义< / p>

这是我的ActivityListener类

 public function __construct(SecurityContext $securityContext, EntityManager $entityManager)
        {
            $this->securityContext = $securityContext;
            $this->entityManager = $entityManager;
        }

这里是services.yml，其中侦听器被定义为服务

services:
    activity_listener:
        class: Bnpp\SecurityBundle\EventListener\ActivityListener
        arguments: [@security.context, @doctrine.orm.entity_manager]
        tags:
        - { name: kernel.event_listener, event: kernel.controller, method: onCoreController }

这是完整的ActivityListenerClass

 <?php

namespace Bnpp\SecurityBundle\EventListener;

use Doctrine\ORM\EntityManager;
//use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Security\Core\SecurityContext;
use Symfony\Component\HttpKernel\Event\FilterControllerEvent;
use Symfony\Component\HttpKernel\HttpKernel;
use Bnpp\SecurityBundle\Entity\User;
use Doctrine\Bundle\DoctrineBundle\Registry;


/**
 * Listener that updates the last activity of the authenticated user
 */

class ActivityListener

    {
    protected $securityContext;
    protected $entityManager;

    public function __construct(SecurityContext $securityContext, EntityManager $entityManager)
    {
        $this->securityContext = $securityContext;
        $this->entityManager = $entityManager;
    }



    /**
     * Update the user "lastActivity" on each request
     * @param FilterControllerEvent $event
     */


    public function onCoreController(FilterControllerEvent $event)
    {

        // Check that the current request is a "MASTER_REQUEST"
        // Ignore any sub-request
        if ($event->getRequestType() !== HttpKernel::MASTER_REQUEST) {
            return;
        }

        // Check token authentication availability
        if ($this->securityContext->getToken()) {
            $user = $this->securityContext->getToken()->getUser();


            if ( ($user instanceof User) && !($user->isActiveNow()) ) {
                $user->setLastActivity(new \DateTime('now'));
                $this->entityManager->flush($user);
            }
        }

    }

}

从此错误中

ContextErrorException：Catchable Fatal Error：传递给Acme \ SecurityBundle \ EventListener \ ActivityListener :: __ construct（）的参数2必须是Doctrine \ ORM \ EntityManager的实例，Doctrine \ Bundle \ DoctrineBundle \ Registry的实例，在C中调用：第350行的\ xampp \ htdocs \ sinfoc \ public \ app \ cache \ dev \ appDevDebugProjectContainer.php，在C：\ xampp \ htdocs \ sinfoc \ public \ src \ Acme \ SecurityBundle \ EventListener \ ActivityListener.php第22行中定义< / p>

你要提供

学说\ ORM \ EntityManager的，

但你提供了

学说\捆绑\ DoctrineBundle \注册表

at

 arguments: [@security.context, @doctrine.orm.entity_manager]

你的论点应该是

arguments:
         - "@security.context"
         - "@doctrine.orm.entity_manager"

Symfony2 - Catchable致命错误：_construct（）必须是Doctrine \ ORM \ EntityManager的实例
