​
要求：
选择线路，点击票价配置，弹出页面，列出线路下的所有站点间的价格，如果没有设置，默认为0.可以修改。
最终实现效果：

核心代码如下：

解释一下：
siteArr和priceMap返回格式大体如下：
siteArr：[{siteId:‘1’,siteName:‘北京站’}，{siteId:‘2’,siteName:‘南京站’}，…]
priceMap: {‘1-2’: ‘1.11’, ‘1-3’: ‘2.22’, 2-3: 3.22 ,…}

样式如下：

本人后端开发，用了一天时间才把前后端开发完毕，特此记录一下

整体代码如下：（框架使用的是jeecg，组件使用的antdesigner，部分组件进行了封装）
