org.hibernate.MappingException无法确定表的类型

Question

这是文件和所有代码 https://www.dropbox.com/sh/n78k0nrkpsrnyqp/AAColiDvxHrI1U2eHocV3GO1a?dl=0

似乎我所遇到的产品实体问题；我收到错误消息，因为“类别”字段的类型为“私人类别”

在我用@entity和@Table注释产品后进入休眠状态时，会显示错误消息

我能使错误消失的唯一方法是如果我注释 @短暂的 私人类别类别

但是我需要将类别保留在表中

那么您如何建议解决此问题

如果类别是实体，则应在 @Entity 中用 @Entity 注释类别类。产品类，您应该提供诸如 1-to-M 之类的关系。
