我设置了以下层次结构：

/src
    /application
        /models
            User.php, Item.php, etc.
   /config
        /mappings
            /yaml
                application.models.User.dcm.yml

这些模型的命名空间为“application\models”。他们都“使用 Doctrine\ORM\Mapping AS ORM”；我在引导程序中使用 Doctrine 的 ClassLoader。这些似乎都有效。

每当我运行该应用程序时，都会出现以下错误：

Warning: class_parents(): Class User does not exist and could not be loaded in /Library/WebServer/Documents/goodsam/library/Doctrine/Common/Persistence/Mapping/RuntimeReflectionService.php on line 40

首先，Doctrine 说 yaml 映射文件必须是完全限定的类名。因此，我将它命名为它指向 application\models 目录的位置。但是在示例文档中，它似乎想要完全限定映射文件本身？这应该是哪一个？

这是我的映射文件的顶部：

# application.models.User.dcm.yml
application\models\User:

如果这看起来是对的，还有其他关于可能被破坏的线索吗？
