【Mybatis】前端傳入參數傳入子查詢

業務描述：

經過用戶code查詢資源菜單，Mybatis中用子查詢查詢子級菜單，須要傳入用戶code進行查詢，用戶code爲登陸token獲取

表結構：

表1：資源表 permission_info

表2：角色資源中間表 role_permission

表3：用戶角色表中間表 member_role

思路：

1. 經過用戶code連表查詢父類菜單code

2. 經過父類code查詢子菜單

3. 經過傳入用戶code查詢再次查詢用戶code，傳入子查詢

4.子查詢再經過父類code和用戶code查詢用戶資源

實現：

<!--查詢用戶資源父類列表-->
 <resultMap id="queryUserPermissionMap" type="com.alibaba.fastjson.JSONObject">
     <result column="permission_url" property="permissionUrl"/>
     <result column="permission_type" property="permissionType"/>
     <result column="permission_description" property="permissionDescription"/>
     <result column="permission_parent_code" property="permissionParentCode"/>
     <result column="permission_code" property="permissionCode"/>
     <collection property="children" column="{permissionParentCode=permission_parent_code,accountCode=accountCode}" javaType="List" select="queryUserPermissionChild">
         <result column="permission_url" property="permissionUrl"/>
         <result column="permission_type" property="permissionType"/>
         <result column="permission_description" property="permissionDescription"/>
         <result column="permission_code" property="permissionCode"/>
     </collection>
 </resultMap>
 <select id="queryUserPermission" parameterType="Map" resultMap="queryUserPermissionMap">
     SELECT
         permission_url,
         permission_type,
         permission_description ,
         permission_parent_code ,
         permission_code,
         (select account_code from member_role where account_code = #{accountCode} Limit 1) as accountCode
     FROM
         permission_info
     WHERE
         state = 1
     AND
         is_menu = 1
     AND
         permission_code
     IN (
         SELECT
             permission_code
         FROM
             role_permission
         WHERE
             role_code
     IN (
         SELECT
             role_code
         FROM
             member_role
         WHERE
             account_code = #{accountCode}))
 </select>

 <!--查詢用戶資源子類列表-->
 <select id="queryUserPermissionChild" parameterType="Map" resultType="com.alibaba.fastjson.JSONObject">
     SELECT
        permission_url ,
        permission_type ,

         permission_info
     WHERE
         state = 1
     AND
         is_menu = 1
     AND
         permission_parent_code = #{permissionParentCode}
     AND
         permission_code
     IN (
         SELECT
             permission_code
         FROM
             role_permission
         WHERE
             role_code
     IN (
         SELECT
             role_code
         FROM
             member_role
         WHERE
             account_code = #{accountCode}))

 </select>

備註：記錄如今的方法，考慮子查詢直接獲取前端傳入參數
