如何禁用参数转换器中的原则过滤器

我在项目中使用了doctrine 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)
{

这很有效，因为如果对象被删除，它会返回NotFound，但是我想授予用户ROLE_ADMIN的访问权限，以便能够看到软删除的内容。

有没有办法让param转换器禁用过滤器，或者我将不得不创建我自己的自定义参数转换器？

目前没有办法做到这一点，但我已经通过创建自己的注释解决了这个问题，它在ParamConverter完成其工作之前禁用了softdeleteable过滤器。

AcmeBundle /注释/ IgnoreSoftDelete.php：

namespace AcmeBundleAnnotation;

use DoctrineCommonAnnotationsAnnotation;

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

AcmeBundle /事件监听/ AnnotationListener.php：

namespace AcmeBundleEventListener;

use DoctrineCommonUtilClassUtils;
use DoctrineCommonAnnotationsReader;
use SymfonyComponentHttpKernelEventFilterControllerEvent;

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 = 'AcmeBundleAnnotationIgnoreSoftDelete';

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

}

AcmeBundle /资源/配置/ services.yml：

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

AcmeBundle /控制器/ DefaultController.php：

namespace AcmeBundleController;

use SymfonyBundleFrameworkBundleControllerController;
use SensioBundleFrameworkExtraBundleConfigurationRoute;
use SensioBundleFrameworkExtraBundleConfigurationTemplate;
use AcmeBundleAnnotationIgnoreSoftDelete;
use AcmeBundleEntityUser;

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。
