Answer 1

第一句说的就是你的 @OneToOne or @ManyToOne出了问题，说明你的配置文件出了问题，一对多或者多队一的关系没有设置正确，你可以去看看配置文件的设置，第二你可以去看一下你的实体类的BeanFactory的引用是否正确。这两个改了之后你再试试。

Answer 2

com.wyb.entity.system.SystemIndustry.category references an unknown entity: com.wyb.entity.system.SystemIndustryCategory
这句话说指向一个未知的实体对象，这个问题是你没有正确配置好实体类。
仔细检查一下是不是对象没有注解table什么的
