我创建了一个自定义过滤器，以检查表属性是否不是“Brouillon”，但当我在Entity中调用它时，什么也没有发生。
以下是我的档案：
NotCaracteristiqueFilter.php:

<?php
// api/src/Filter/RegexpFilter.php

namespace App\Filter;

use Doctrine\ORM\QueryBuilder;
use ApiPlatform\Metadata\Operation;
use Symfony\Component\PropertyInfo\Type;
use ApiPlatform\Doctrine\Orm\Filter\AbstractFilter;
use ApiPlatform\Core\Bridge\Doctrine\Orm\Filter\BooleanFilter;
use ApiPlatform\Doctrine\Orm\Util\QueryNameGeneratorInterface;

final class NotCaracteristiqueFilter extends BooleanFilter
{
    public function apply(QueryBuilder $queryBuilder, QueryNameGeneratorInterface $queryNameGenerator, string $resourceClass, ?string $operationName = null, array $context = [])    {

            $value = $this->extractProperties([$this->getProperties()], $queryBuilder);

            if ($value === true) {
                $rootAlias = $queryBuilder->getRootAliases()[0];
                $queryBuilder->andWhere(sprintf('%s.etuCaracteristique != :brouillon', $rootAlias));
                $queryBuilder->setParameter('brouillon', 'Brouillon');
            }

    }

}

service.yaml：

# This file is the entry point to configure your own services.
# Files in the packages/ subdirectory configure your dependencies.

# Put parameters here that don't need to change on each machine where the app is deployed
# https://symfony.com/doc/current/best_practices.html#use-parameters-for-application-configuration
parameters:

services:
    # default configuration for services in *this* file
    _defaults:
        autowire: true      # Automatically injects dependencies in your services.
        autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.

    # makes classes in src/ available to be used as services
    # this creates a service per class whose id is the fully-qualified class name
    App\:
        resource: '../src/'
        exclude:
            - '../src/DependencyInjection/'
            - '../src/Entity/'
            - '../src/Kernel.php'
            - '../src/EventListener/'

    App\Filter\NotCaracteristiqueFilter:
        
    # add more service definitions when explicit configuration is needed
    # please note that last definitions always *replace* previous ones

我已经检查了API Platform的文档，以配置自定义过滤器，我检查了互联网上的其他来源，但我发现没有任何看起来像我的情况下，即使在堆栈溢出。我也清除了我的缓存，检查我的Symphony日志，但没有问题一直显示。Ib还试图错误配置我的过滤器，以检查它是否甚至检测到，它显示了一个错误，这让我认为我的过滤器被检测到。
