ibatis问题

1001
Hibernate: select stuinfo0_.id as id1_0_, stuinfo0_.name as name1_0_, stuinfo0_.sex as sex1_0_, stuinfo0_.tel as tel1_0_ from studb.dbo.stuinfo stuinfo0_ where stuinfo0_.id=?
Hibernate: insert into studb.dbo.stuinfo (name, sex, tel) values (?, ?, ?) select scope_identity()
我用 hibernate自动生成的方法做save,明明是传了一个bean对象过去的
而且id也是取的到的,为什么执行save时,id没有被执行啊,导致插入数据失败
