毕业后找工作玩了五个月
终于在当地制药公司找到了工作，成为了光荣的软件工程师助理。 主管教我开发钉钉的小程序用于企业人事。
入职前几天，出于预习技能的考虑，去了钉钉官网，打算开发钉钉的小程序。
订书机的小程序安装git，但我的电脑上没有。 没关系。 请整理一下。
多次下单都没有反应
一直在关闭浏览器弹匣块、允许JS插件、关闭重定向块、关闭电脑第三方防火墙、呈现err_connection_reset
最后复制了下载链接并用迅雷下载了。 迅雷yyds
安装了订书机的小程序开发环境
于是，不愉快的下午结束了！
基坑1 :
根据官方文档教程，下载后端demo后，我们发现它在idea上不起作用

改好后IDEA上可以跑了
坑2：
根据官方文档教程，本地运行打包好的jar包，发现运行不了
报错
排查中。。。。要不是得打工，我才不侍候你这破钉钉
坑3：同样是小程序，有两个下载链接
咋办捏。。。随便挑一个吧!
不知道后面还有什么奇奇怪怪的坑，自学springboot去了。
