在ibatis和mysql环境下使用insert如何获取返回值

1     <insert id="insertAndGetId" parameterClass="Vnet_stack" >  
2         insert into
3         vnet_stack(stack_name)
4         values(#stack_name#)
5         <selectKey resultClass="int" keyProperty="stack_id" >
6             SELECT LAST_INSERT_ID()
7         </selectKey>
8         
9     </insert>

1     @Override
2     public int insertAndGetId(Vnet_stack ss) {
3         // TODO Auto-generated method stub
4         return Integer.parseInt(String.valueOf(getSqlMapClientTemplate().insert("Vnet_stack.insertAndGetId",ss)));
5         
6     }
