解决方案参考

  1. 使用spring的ResourceUtils.getFile读取jar包内文件失败

项目没做完，没写打包脚本，自己写个gradle打包任务就行了，主要思路是把资源文件拷贝到打包目录下。

项目没做完，没写打包脚本，自己写个gradle这个打包任务就行了，主要思路是把资源文件拷贝到打包目录下。

我fork修改了下，提交了合并请求，不嫌弃的话可以合并。 最后，谢谢开源 image

从接口协议设计的角度讲，两个列车号（TrainNo && TrainCode ）会让用户产生误解，先暂时这样做吧

那得想办法搞到所有的列车信息（或 通过查票 查询后 永久存储）不然丢失掉会导致 经停查询 接口失效

似乎12306接口更新了，需要携带cookie才能查询了
