Answer 1

检测一下t_user 字段和数据库的映射上是不是对应的

Answer 2

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'regdate' in 'field list' regdate 是否在数据库中正确拼写..hbm也看看 提示说不认识regdate这个字段名

Answer 3

Unknown column 'regdate' in 'field list'
好好看下这一句

Answer 4

会不会是版本兼容问题？
我用的struts1.3.10 + hibernate3.2 + spring2.5

Answer 5

就是啊……
不过问题解决了，我把regdate字段删除了然后再加上就没问题了，真是奇怪。折磨了我半天的问题解决了都不知道啥回事儿……

Answer 6

应该是你的regdate 传值 或者是映射的问题
