中collection多参数传递

引用：/fortunate_leixin/article/details/126320852

传递多个参数时：

 <resultMap id="BillStandardHighRuleResult" type="">
        <result property="id" column="id"/>
        <result property="standardId" column="standard_id"/>
        <result property="archive" column="archive"/>
        <collection property="highList" column="{id= id,standardId= standard_id}" select="getChildById"/>
    </resultMap>

   <select id="getChildById" resultType="xxxx">
        SELECT
        a.id,
        a.standard_id,
        a.bbb,
        a.ccc,
        a.standard_id 
        FROM
            `aaaa` a
        WHERE
            a.id= #{id}
            a.standard_id = #{standardId}
            and a.del_flag = '0'
    </select>

 多参数时在column中用"{}"将参数包起来， =左边的为是mapper中定义的param的属性， =右边的是主查询中的表字段名  

传递一个参数时：

 <collection property="childList" column="id" select="getChildList"/>
