根据在 Symfony 中调用的位置阻止监听器被激活

Question

我有一个包含很多捆绑包的 Symfony 项目。

在其中一个中，我有一个像这样的标准 Doctrine 监听器：

class MyListener

{

    public function postLoad(LifecycleEventArgs $args)

    {

        $entity = $args->getObject();

        if ($entity instanceof MyEntity) {

            //do something

        }

...

现在我创建了一个新的 Bundle，它也将这些实体加载到控制器中。

正如预期的那样，它还触发了监听器中的 postLoad。

我需要它不要触发它，或者如果它是由这个 Bundle/Controller 触发的，则不要执行任何操作，例如：

class MyListener

{

    public function postLoad(LifecycleEventArgs $args)

    {

        $entity = $args->getObject();

        if ($caller = "DontTriggerBundle")

            return true;

        }

        if ($entity instanceof MyEntity) {

            //do something

        }

...

有没有办法做到这一点？提前致谢

所以这就是我解决它的方法：将请求堆栈添加到服务：<service id="myservice>&nbsp; &nbsp; <argument type="service" id="request_stack"/></service>然后得到这样的控制器：// src/AppBundle/EventListener/AcmeListener.phpnamespace AppBundle\EventListener;use Doctrine\ORM\Event\LifecycleEventArgs;use Symfony\Component\HttpFoundation\Request;use Symfony\Component\HttpFoundation\RequestStack;class AcmeListener{&nbsp; &nbsp; /** @var Request */&nbsp; &nbsp; protected $request;&nbsp; &nbsp; /**&nbsp; &nbsp; &nbsp;* AcmeListener constructor.&nbsp; &nbsp; &nbsp;*&nbsp; &nbsp; &nbsp;* @param RequestStack $requestStack&nbsp; &nbsp; &nbsp;*/&nbsp; &nbsp; public function __construct(RequestStack $requestStack)&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; $this->request = $requestStack->getCurrentRequest();&nbsp; &nbsp; }&nbsp; &nbsp; /**&nbsp; &nbsp; &nbsp;* @param LifecycleEventArgs $args&nbsp; &nbsp; &nbsp;*/&nbsp; &nbsp; public function postLoad(LifecycleEventArgs $args)&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; $controller = $this->request->attributes->get('_controller');&nbsp; &nbsp; &nbsp; &nbsp; if (strpos($controller, 'DontTriggerController::indexAction') !== false) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Do nothing&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; // Do somethings&nbsp; &nbsp; }}希望这可以帮助某人
