我正在研究symfony2项目,我得到了这个例外.谁知道造成它的原因是什么？
未捕获的异常'Symfony\Component\Security\Core\Exception\AccessDeniedException',在/ data/apache/www/emploipublic-sf/vendor/symfony/symfony/src/Symfony/Component/Security/Http/Firewall中显示消息'Access Denied' /AccessListener.php:70\n

private $context;
private $accessDecisionManager;
private $map;
private $authManager;
private $logger;

$this->context = $context;
$this->accessDecisionManager = $accessDecisionManager;
$this->map = $map;
$this->authManager = $authManager;
$this->logger = $logger;
}

throw new AuthenticationCredentialsNotFoundException('A Token was not found in the SecurityContext.');
}
$request = $event->getRequest();

$this->context->setToken($token);
}
if (!$this->accessDecisionManager->decide($token, $attributes, $request)) {

}
}
