【Mybatis】錯誤 java.lang.UnsupportedOperationException

報錯信息以下：

Caused by: org.apache.ibatis.exceptions.PersistenceException: 
### Error querying database.  Cause: java.lang.UnsupportedOperationException

異常根源： resultType返回的是集合中的元素類型，而不是集合自己

代碼以下：

<!--查詢詳細訂單信息-->
    <resultMap id="orderDetailMap" type="com.alibaba.fastjson.JSONArray">
        <result column="order_code" property="orderCode"/>
        <result column="state" property="state"/>

        WHERE
            order_code = #{orderCode}
    </select>

錯誤緣由：

<resultMap id="orderDetailMap" type="com.alibaba.fastjson.JSONArray">
    中JSONArray類型錯誤，修改成
    <resultMap id="orderDetailMap" type="com.alibaba.fastjson.JSONObject">

說明：此處類型是如今開發使用類型，若是使用的是對象，則查看resultMap中 type類型是List仍是對象，若是是關聯子查詢，修改成對象
