SSM框架实现⼩程序前后端数据通信样例项⽬（附完整的项⽬样例⼯程源
码）
因为最近的项⽬需要，简单提供⼀个⼩程序与Java后端进⾏数据交互的项⽬模板，同时也建⽴了⽹页WEB的测试，⽅便搭建pc端后台管理界⾯。因为有些内容⽹上也⽐较多，部分环境安装和项⽬创建内容不加强调。下⾯进⼊主题吧：
1、使⽤⼯具：
（1）⼩程序开发者⼯具
（2）IDEA
（3）SSM框架
（4）MySQL数据库
2.⼩程序前端框架
这个就不多介绍了，下载安装好开发环境，建⽴项⽬，会⾃动创建⼀个框架模板。
3.SSM框架搭建
（1）创建项⽬，选择创建Maven项⽬，选择其中的webapp模板，这个也不在累赘，可搜索相关博客如何创建⼀个Maven管理的Java Web项⽬模板。
（2）框架相关配置⽂件设⽴
⾸先本项⽬的后端⽬录结构如下：
3.1 Java⽂件模板建⽴
（1）配置l⽂件
特别需要注意⼀下数据库的版本以及⼀些项⽬⼯程信息可能需要改成你的⼯程名字，本项⽬名称为：Minqingtong_System

（2）配置l⽂件
如果有标红报错的地⽅，先不管，等创建好相应的⽂件后，回过来看是否是⽂件名不⼀致。
