MAP传参需仔细

在PO中

private Date birthday;

有业务将birthday SET进mobileDO中,在Service中

Map<String, Object> map=null;
map=BeanUtils.describe(mobileDO);

在iBATIS中

<update id="updateOBJ" parameterClass="java.util.Map">
     update Mobile
    <dynamic prepend="set" >
      <isNotNull prepend="," property="mobile" >
        Mobile = #mobile:VARCHAR#
      </isNotNull>
       <isNotNull prepend="," property="birthday" >
        Birthday = #birthday:TIMESTAMP#
      </isNotNull>
</dynamic>
    where ID = #ID:INTEGER#
</update>

执行时一直报错，说日期格式不正确,最后问了老大，才知道上面MAP里是<String, Object>,那么日期就变String型了,而iBATIS却是将它定义为日期型
