我正在使用带有自动接线调度程序的服务来调度事件.为了测试事件,我在调度事件之前添加了一个事件订阅者.但是,注册订户没有记录我希望它执行的方法.

事件：

<?php

namespace App\Event;

use Symfony\Component\EventDispatcher\Event;

class GameStartEvent extends Event {

}

订户：

<?php

namespace App\Event;

use Psr\Log\LoggerAwareTrait;
use Psr\Log\LoggerInterface;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class GameStartSubscriber implements EventSubscriberInterface {

    use LoggerAwareTrait;

    public function __construct(LoggerInterface $logger) {
        $this->setLogger($logger);
    }

    public static function getSubscribedEvents() {
        return [
            "game.started" => [
                [
                    'logEvent',
                ],
            ]
        ];
    }

    public function logEvent(GameStartEvent $event): void {
        $this->logger->info("the game has started");
    }
}

这是使用过的服务,用于分派事件,而事件注册应该在将来的其他地方发生.我只是在这里做测试：

<?php

namespace App\Service;

use App\Event\GameStartEvent;
use App\Event\GameStartSubscriber;
use Psr\Log\LoggerInterface;
use Psr\SimpleCache\CacheInterface;
use Symfony\Component\EventDispatcher\EventDispatcherInterface;

class GameCacheService {

    private $eventDispatcher;

    private $logger;

    public function __construct(EventDispatcherInterface $eventDispatcher, LoggerInterface $logger) {
        $this->eventDispatcher = $eventDispatcher;
        $this->logger = $logger;
    }

    // some other methods...

    function startGame() {
        // some code...

        $gameStartSubscriber = new GameStartSubscriber($this->logger);
        $this->eventDispatcher->addSubscriber($gameStartSubscriber);

        $this->eventDispatcher->dispatch("game.started", new GameStartEvent());   
    }
}

调用服务方法后,不会记录指定的记录器消息.

解决方法:

更换

$this-> eventDispatcher-> dispatch(“ game.started”,new GameStartEvent());`

与

$this-> eventDispatcher-> dispatch(“ game.started”,$event);`

您似乎在App / Entity中至少拥有您的事件,该事件默认情况下不会自动关联,因此不应该自动关联.看一下您的services.yml,应该将其排除在自动装配之外.将您的东西移动到类似App / Event的地方
