您可以实现一个实现EventSubscriberInterface的事件订阅者：

<?php 
namespace App\EventSubscriber;

use ApiPlatform\Core\EventListener\EventPriorities;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Event\GetResponseForControllerResultEvent;
use Symfony\Component\HttpKernel\KernelEvents;

final class DeleteEntityNameSubscriber implements EventSubscriberInterface
{

    public function __construct()
    {
        // Inject the services you need
    }

    public static function getSubscribedEvents()
    {
        return [
            KernelEvents::VIEW => ['onDeleteAction', EventPriorities::PRE_WRITE]
        ];
    }

    public function onDeleteAction(GetResponseForControllerResultEvent $event)
    {
        $object = $event->getControllerResult();
        $request = $event->getRequest();
        $method = $request->getMethod();

        if (!$object instanceof MyEntity || Request::METHOD_DELETE !== $method) {
            return;
        }

       // Do you staff here
    }

}

我知道这个问题是相当古老的，但它出现在谷歌结果。
您可以通过添加write: false（禁用端点的自动删除和刷新功能）将路由配置为不删除实体：

collectionOperations={
 *         "customObjectRemove": {
 *             "method": "DELETE",
 *             "path": "/objects/{id}/custom_remove",
 *             "controller": CustomObjectRemoveController::class,
 *             "write": false

注意：您需要在事件订阅者中添加flush，否则将不保存更改。
