Question

我对symfony2有疑问。虽然加载页面symfony在这里加载内核超过1次是转储..

有人这个问题吗？版本2.6.9

不，你正在阅读错误的日志。这不是Symfony不止一次加载内核，也就是Symfony将内核事件通知给所有感兴趣的订阅者。它完全没问题，你不必担心它。

当然每次页面加载时你可能会有几个请求，所以你必须检查它。

您应该排除子请求（内部请求或重定向）。请参阅http://symfony.com/doc/current/cookbook/service_container/event_listener.html#request-events-checking-types。
您可能希望排除资产等。

这是一个改编自我使用的实际听众的样本：

public function onKernelRequest(GetResponseEvent $event)
{
    // Exclude subrequests
    if ($event->getRequestType() != HttpKernelInterface::MASTER_REQUEST)
    {
        return;
    }

    // Exclude assets
    $route = $event->getRequest()->get('_route');
    if (strpos($route, "_") === 0) {
        return;
    }
}

Symfony2调用内核超过1次
