一开始我的注意力集中在 Duplicate class/entity mapping Model.Login所以一直去找Login的映射因为错误提示是重复的类
后来找了同学帮忙他在debug中发现了如下错误

Error applying BeanValidation relational constraints百度了一下这个错误发现一个方法
在hibernate中加入<property name="javax.persistence.validation.mode">none</property>
然后错误就解决了至今还不知道为什么报Duplicate class/entity mapping Model.Login这个错误。
