最有用到mybatis返回一个map结果集，然后就针对性的在网上找了一些相关大牛的总结：1.https://www.cnblogs.com/jwdd/p/10046270.html

1、如果你确定返回的数据只有一条，你可以这样整 xml中：
<select id="searchncomedateByInvestID" resultMap="java.util.HashMap"> select t1.invest_id , cast(t1.modify_time AS DATE) modify_time from t_c_wh_redeeminfo t1 where 1=1 and t1.invest_id =#{investId} </select>
dao中：
Map<String,Object> searchncomedateByInvestID(investId);
2、如果返回的是多条数据，可以这样整 xml中：
<resultMap id="getAllSetDaysResult" type="HashMap">
<result property="investid" column="invest_id" jdbcType="VARCHAR" />
<result property="modifytime" column="modify_time" jdbcType="DATE"/>
</resultMap>
<select id="searchncomedateByInvestID" parameterType="java.util.List" resultMap="getAllSetDaysResult">
select
t1.invest_id ,
cast(t1.modify_time AS DATE) modify_time
from t_c_wh_redeeminfo t1
where 1=1
and t1.invest_id in
<foreach collection="list" item="investId" index="index" open="(" close=")" separator=",">
#{investId}
</foreach>
</select>
dao中：
List<Map<String, Object>> searchncomedateByInvestID(List<String> preinvestList);
