微信小程序以ssm做后台开发的实现示例
微信小程序任何的语言都可以做后台，现在微信小程序推出云函数，做后台也可以。但是自己感觉想要完整的后台，做后台用java和php更好点。下面以典型的例证给大家做一下讲解，注册。
1、wmxl
微信小程序的前段代码（提交数据主要以from表单实现的）

3、js
js是重点，他是一个中间桥梁，获取微信小程序前端的数值和传导ssm的后台。
wx.request这是微信的接口，也就是发起请求。
url: ‘http://localhost:8080/lg/wechat/add,这就是你的项目的地址，也就是controller。
dada就是你要传到后台的数据。
接下来是完整的js代码（获取表单的数据，这里的js包括获取openid，如果你使用，直接删除就可以）

4、ssm的后端实现
因为小程序的数据格式都是json格式，所以我们的ssm后台也必须是就json的格式，Java要实现json的格式，需要对应的jar包，打下自行-。
