在做多表映射查询时，在同一个resultMap中写了1:1映射和1:n映射，结果测试时报错如下：

org.apache.ibatis.exceptions.PersistenceException:

这是说类型不匹配，第一反应肯定是resultMap中属性名写错了，结果看了好几遍，没有任何错，这个时候也是懵的，将1:1或者1:n映射注释一个留一个单独测试都是正常的，放一起就错了，代码如下：

 <resultMap type="OrderCustom" id="L_ODC_M" extends="O_B">
        <collection property="odc" ofType="OrderDetailCustom">
            <result column="items_id" property="items_id"/>
            <result column="items_num" property="items_num"/>
        </collection>
        
        <association property="uc"  javaType="UserCustom">
            <result column="username" property="username"/>
            <result column="sex" property="sex"/>
        </association>
    </resultMap>

无意中将两个映射的顺序调换之后就不报错了，如下：

 <resultMap type="OrderCustom" id="L_ODC_M" extends="O_B">
    
        <association property="uc"  javaType="UserCustom">
            <result column="username" property="username"/>
            <result column="sex" property="sex"/>
        </association>
    
        <collection property="odc" ofType="OrderDetailCustom">
            <result column="items_id" property="items_id"/>
            <result column="items_num" property="items_num"/>
        </collection>

</resultMap>

去查了一下原来是新版本对顺序有了要求，1:n要在1:1后面。
