"Class is not a valid entity..." EntityManager#getClassMetadata(...) 错误

Question

我正在尝试为 post 在 Doctrine 的 GitHub 页面上编写一个测试用例，但在生成模式时遇到了问题。来电

$this->_em->getClassMetadata(Server::class)

导致异常

Class "Doctrine\Tests\Models\DDC6786\Server" is not a valid entity or mapped super class.

我做错了什么？ / 如何让它工作？

代码

Answer 1

问题是由注释引起的。 use Doctrine\ORM\Mapping as ORM; & @ORM\Entity 不起作用，但只有 @ORM\Entity（和 @ORM\Table 等）起作用。
