doctrine-orm - zf2 的学说映射异常 :class "" does not exist?

Question

我正在使用 zf2 和doctrine2 创建用户 Controller ，我的注册操作工作正常，但在登录操作中，我收到如下异常:

F:\PHP\EasySurvey\vendor\doctrine\common\lib\Doctrine\Common\Persistence\Mapping\MappingException.php:96

消息:

Class '' does not exist

Answer 1

从快速 View 来看，属性 DoctrineModule\Options\Authentication::$identityClass 似乎未设置。

这就是您收到空类不存在错误的原因。
