org.hibernate.MappingException: Could not read mappings from resource: blog/href/dao/Hreftab.hbm.xml
-----------------------------------------------
你的这Hreftab.hbm.xml里面的mappings配置不正确，你检查一下
[解决办法]
你过你配置的字段长度和数据库真实的字段长度不同，会出现有时可以，有时报错的问题
[解决办法]
注意看
Caused by: org.hibernate.DuplicateMappingException: Duplicate class/entity mapping blog.href.dao.Hreftab
blog.href.dao.Hreftab这个类被多个hbm.xml映射了
