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
2.https://www.codercto.com/a/33475.html 然后经过自己的测试终于可以应用实际业务中
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);

实际应用:
