当我使用“php bin/console debug：router”命令时，我得到以下结果：
命名方法方案主机路径
_preview_error ANY ANY ANY /_error/{code}.{_format}
所以这意味着我的路由没有被找到。我希望/和/add-sample路由在那里。
访问http://127.0.0.1:8000/api/parties上的端点时出现404错误
Symfony\Component\Routing\Exception\ ResourceNotFoundException
No routes found for "/api/parties/".

我的路由未被识别的原因是什么？

app_party:
    resource: App\Controller\PartyController

PartyController.php：
