Solve mybatis error Result Maps collection does not contain value for java.lang.Integer

 

Solution:
1. Check the xml configuration of mybatis

2. There must be a mismatch somewhere, such as "resultMap" --> "resultType"

[html] view plain copy
<select id="getNumDayMoney" resultMap="java.lang.Integer" parameterType="java.lang.Integer">
<![CDATA[
select sum(money) from dw_account_recharge where user_id = #{userId}
AND addtime < UNIX_TIMESTAMP(
date_sub(curdate(), INTERVAL - 1 DAY)
)
AND addtime > UNIX_TIMESTAMP(
date_sub(curdate(), INTERVAL 1 DAY)
)
]]>
</select>
修改为:
[html] view plain copy
<select id="getNumDayMoney" resultType="java.lang.Integer" parameterType="java.lang.Integer">
<![CDATA[
select sum(money) from dw_account_recharge where user_id = #{userId}
AND addtime < UNIX_TIMESTAMP(
date_sub(curdate(), INTERVAL - 1 DAY)
)
AND addtime > UNIX_TIMESTAMP(
date_sub(curdate(), INTERVAL 1 DAY)
)
]]>
</select>
