这个错误是自己开发过程中不细心导致的，特记下来，作为警惕。

mysql分页 limit中需要整数，结果自己 dao层写成了String 类型，（低级错误）
<select id="queryPastLimit" resultMap="BaseResultMap">
select <include refid="Base_Column_List"/>
from hui_app_lottery_past
where lotterytype = #{lotterytype}
<if test="issuenumber != null and '' !=issuenumber">
<![CDATA[ and issuenumber < #{issuenumber} ]]>
</if>
order by issuenumber desc limit #{pageSize}
</select>
dao层： public List<LotteryPast> queryPastLimit(@Param("issuenumber")String issuenumber,@Param("lotterytype")String lotterytype,@Param("pageSize") String pageSize);
正确写法为 ：public List<LotteryPast> queryPastLimit(@Param("issuenumber")String issuenumber,@Param("lotterytype")String lotterytype,@Param("pageSize") int pageSize);
