JSR如何双层数据对象获取对应关系
场景：我有两个对象数据：分别是：_defaultPrivilegeIcont 和 userConfig
需要实现的效果：
1、_defaultPrivilegeIcont 可以通过userConfig的awardListVO[xx][xx]item和levelCode 赋值到_defaultPrivilegeIcont的describe变成动态的赋值的效果；例如：_defaultPrivilegeIcont[0].list[0].describe = 'VIP1可享' 其中VIP1取的就是的userConfig的item,然后拿到的levelCode关系；
2、如果同时多个等级匹配中 需要获取最低的那个；比如：userConfig.awardListVO里面的item 有多个1 那么_defaultPrivilegeIcont[0].list.describe 就显示VIP1 获取的是等级最低的那个levelCode
实现了很多的方式都无法得到理想的状态；请知道的大佬帮忙看一下

回答：
几个疑问
(1) 示例中的 VIP1可享 压根没出现在数据中啊，所以这个信息从哪里来？
(2) 我分析了一下 userConfig 中 levelCode 和 item 的关系，结果如下
[ { levelCode: 0, items: [] },
{ levelCode: 1, items: [ 1 ] },
{ levelCode: 2, items: [ 1, 6 ] },
{ levelCode: 3, items: [ 1, 3, 6 ] },
{ levelCode: 4, items: [ 1, 3, 6 ] },
{ levelCode: 5, items: [ 1, 3, 6 ] },
{ levelCode: 6, items: [ 1, 3, 6 ] },
{ levelCode: 7, items: [ 1, 3, 6, 7 ] },
{ levelCode: 8, items: [ 1, 3, 6, 7 ] },
{ levelCode: 9, items: [ 1, 2, 3, 4, 5, 6, 7, 8 ]},
{ levelCode: 10, items: [ 1, 2, 3, 4, 5, 6, 7, 8 ]},
{ levelCode: 11, items: [ 1, 2, 3, 4, 5, 6, 7, 8 ]}
]
确实存在一个 item 对应着多个 levelCode 的情况，但是 _defaultPrivilegeIcont.list 中的每一项都有 levelCode 值，为什么会需要按 item 去找最小的 levelCode？
(3) 算是一个建议：要找到 (2) 中描述的关系其实很容易，可以倒转过来建建立一个 item 到多个 levelCode 的映射，这时候要先找 item，再去找对应的最小 levelCode 就很容易了
