我对表的查询修改删除都没问题，但是在增加的时候包不支持数据库主键策略

我的数据库UserT这表的uid是自动增长的主键。

-------------------------------------------------------

UserT.hbm.xml





 <class name="com.entity.vo.UserT" table="userT" schema="dbo" catalog="testSSH">

        <id name="uid" type="java.lang.Integer">

            <column name="uId" />

            <generator class="identity"></generator>

        </id>



--------------------------------------------------------

create table userT(

uId    int identity primary key,

uUame  varchar(20),

uAge   int,

uSex   int

)

go

--------------------------------------------------------

还打印了hibernate的HQL语句：

Hibernate: insert into testSSH.dbo.userT (uUame, uAge, uSex) values (?, ?, ?)



数据的uid增长了一位，但是数据好像是回滚了。























等高手。
