Invocation of init method failed; nested exception is org.hibernate.InvalidMappingException: Could n

今天在写ssh的时候遇到了一个这样的问题，连登陆页面都进不去了
报错信息如下:

主要错误为:

Invocation of init method failed; nested exception is org.hibernate.InvalidMappingException: Could not parse mapping document from input stream

翻译:
调用init方法失败；嵌套异常为org.hibernate.无效的映射异常:无法从输入流分析映射文档

问题所在:

将hibernate反向生成的映射文件配置路径删除，因为上面已经配置好了改目录下的所有.xml文件，所以就不要重新配置了

解决方法:
删除上图中property所在的映射配置
