升级Api-Platform 2.7后getCollection接口报资源类未找到异常

当前API基于PHP8.1、Symfony 6.1和Api-Platform 2.6，计划升级至Api-Platform 3.0。先升级到Api-Platform 2.7并将metadata_backward_compatibility_layer标志设为false后，所有getCollection端点出现错误，其他端点运行正常。抛出异常ApiPlatform\Exception\ResourceClassNotFoundException，提示信息：Resource "App\Entity\RatingAttribute" not found。

问题定位 #

错误来自vendor/api-platform/core/src/Core/Metadata/Resource/Factory/ExtractorResourceMetadataFactory.php第54行的这段代码：

if (!(class_exists($resourceClass) || interface_exists($resourceClass)) || !$resource = $this->extractor->getResources()[$resourceClass] ?? false) {
    return $this->handleNotFound($parentResourceMetadata, $resourceClass);
}

注释掉这段代码后，所有功能均可正常运行。
