以上就是我在学习mybatis中，定义statement时，把resultMap定义成了resultType，所以出现了这样的错误信息。



<!-- 查询订单关联查询用户信息,使用resultMap -->

<select id="findOrdersUserResultMap"
resultType="OrdersUserResultMap">

SELECT 

orders.*,

  USER.username,

  USER.sex,

  USER.address 

FROM

  orders,

  USER 

WHERE orders.user_id = user.id

</select>

    细节真的很重要，害我检查了好长时间，第二次了，好懵逼的感觉。。。。
