我在一个项目上使用了学说 softdeleteable 扩展，并设置了我的控制器操作。

/**
 * @Route("address/{id}/")
 * @Method("GET")
 * @ParamConverter("address", class="MyBundle:Address")
 * @Security("is_granted('view', address)")
 */
public function getAddressAction(Address $address)
{

这很好用，因为如果对象被删除，它会返回 NotFound，但是我想授予具有 ROLE_ADMIN 的用户访问权限，以便能够查看软删除的内容。

是否已经存在让参数转换器禁用过滤器的方法，还是我必须创建自己的自定义参数转换器？

没有现有的方法可以做到这一点，但我已经通过创建自己的注释解决了这个问题，它在完成工作softdeleteable之前禁用过滤器。ParamConverter

AcmeBundle/注释/IgnoreSoftDelete.php：

namespace AcmeBundle\Annotation;

use Doctrine\Common\Annotations\Annotation;

/**
 * @Annotation
 * @Target({"CLASS", "METHOD"})
 */
class IgnoreSoftDelete extends Annotation { }

AcmeBundle/EventListener/AnnotationListener.php：

namespace AcmeBundle\EventListener;

use Doctrine\Common\Util\ClassUtils;
use Doctrine\Common\Annotations\Reader;
use Symfony\Component\HttpKernel\Event\FilterControllerEvent;

class AnnotationListener {

    protected $reader;

    public function __construct(Reader $reader) {
        $this->reader = $reader;
    }

    public function onKernelController(FilterControllerEvent $event) {
        if (!is_array($controller = $event->getController())) {
            return;
        }

        list($controller, $method, ) = $controller;

        $this->ignoreSoftDeleteAnnotation($controller, $method);
    }

    private function readAnnotation($controller, $method, $annotation) {
        $classReflection = new \ReflectionClass(ClassUtils::getClass($controller));
        $classAnnotation = $this->reader->getClassAnnotation($classReflection, $annotation);

        $objectReflection = new \ReflectionObject($controller);
        $methodReflection = $objectReflection->getMethod($method);
        $methodAnnotation = $this->reader->getMethodAnnotation($methodReflection, $annotation);

        if (!$classAnnotation && !$methodAnnotation) {
            return false;
        }

        return [$classAnnotation, $classReflection, $methodAnnotation, $methodReflection];
    }

    private function ignoreSoftDeleteAnnotation($controller, $method) {
        static $class = 'AcmeBundle\Annotation\IgnoreSoftDelete';

        if ($this->readAnnotation($controller, $method, $class)) {
            $em = $controller->get('doctrine.orm.entity_manager');
            $em->getFilters()->disable('softdeleteable');
        }
    }

}

AcmeBundle/Resources/config/services.yml：

services:
    acme.annotation_listener:
        class: AcmeBundle\EventListener\AnnotationListener
        arguments: [@annotation_reader]
        tags:
            - { name: kernel.event_listener, event: kernel.controller }

AcmeBundle/Controller/DefaultController.php：

namespace AcmeBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use AcmeBundle\Annotation\IgnoreSoftDelete;
use AcmeBundle\Entity\User;

class DefaultController extends Controller {

    /**
     * @Route("/{id}")
     * @IgnoreSoftDelete
     * @Template
     */
    public function indexAction(User $user) {
        return ['user' => $user];
    }

}

注释可以应用于单个操作方法和整个控制器类。
