zend-framework - ZF3 : SharedEventManager injection in EventManager

Question

在 ZF2 中，使用共享事件管理器在多个 Controller 之间共享事件

模块.php

use Zend\Mvc\MvcEvent;

class Module
{
    public function getConfig()
    {
        return include __DIR__ . '/../config/module.config.php';
    }

    public function onBootstrap(MvcEvent $event)
    {
        $services = $event->getApplication()->getServiceManager();
        $sharedEventManager = $eventManager->getSharedManager();

        $sharedEventManager->attach('user', 'log-fail', function($event) use ($services) {
            $username = $event->getParam('username');
            $log = $services->get('log');
            $log->warn('Error logging user: ' . $username);
        });
    }
}

LogController.php

<?php

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\EventManager\EventManager;

class LogController extends AbstractActionController
{
    public function __construct()
    {
    }

    public function inAction()
    {
        //...
        if (! $isValid) {
            $event = new EventManager('user');
            $event->trigger('log-fail', $this, array('username'=> $username));
            //...
        }
    }
}

但是 ZF3 要求在实例化时注入(inject)共享事件管理器，而不是通过 setter。 https://docs.zendframework.com/zend-eventmanager/migration/changed/

所以我创建了一个日志 Controller 工厂来注入(inject)共享事件管理器，但我找不到如何进行注入(inject)

LogControllerFactory.php

<?php

namespace Application\Controller;

use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;

class LogControllerFactory implements FactoryInterface
{
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
    {
        $sharedEventManager = ???

        return new LogController($sharedEventManager);
    }
}

您是否知道如何实例化共享事件管理器以将其注入(inject) Controller 中，以便将其放入 Controller __construct 函数中？
