这篇文章主要讲解了“微信小程序怎么用ssm做后台开发”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“微信小程序怎么用ssm做后台开发”吧！
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）
<view class="btn-submit">
<button formType="reset">请完善注册信息</button>
</view>
<form catchsubmit="formSubmit" catchreset="formReset">
<view class="input-list">
<view class="input-item">
<text class="input-item-label">姓名</text>
<view class="input-item-content">
<input type="text" name="name" auto-focus placeholder="请输入您的姓名" bindinput="inputName"></input>
</view>
</view>
<view class="input-item">
<text class="input-item-label">性别</text>
<picker class="input-item-content" bindchange="bindPickerChange" data-pickername="industry" value="{{industryindex}}" range="{{industryarr}}" mode="selector">{{industryarr[industryindex]}}
</picker>
</view>
<view class="input-item">
<text class="input-item-label">账号</text>
<view class="input-item-content">
<input type="idcard" name="tel" placeholder="请输入您的手机号码" maxlength="11" bindinput="inputPhone"></input>
</view>
</view>
<view class="input-item">
<text class="input-item-label">登录密码</text>
<view class="input-item-content">
<input type="password" name="password" auto-focus placeholder="请设置登录密码" bindinput="inputName"></input>
</view>
</view>
<view class="input-item">
<text class="input-item-label">邮箱</text>
<view class="input-item-content">
<input type="text" name="email" auto-focus placeholder="请输入您的邮箱" bindinput="inputName"></input>
</view>
</view>
<view class="input-item">
<text class="input-item-label">注册vip</text>
<picker class="input-item-content" bindchange="bindPickerChange" data-pickername="status" value="{{statusindex}}" range="{{statusarr}}" mode="selector">{{statusarr[statusindex]}}
</picker>
</view>
</view>
<view class="btn-submit">
<button type="primary" formType="submit">提交</button>
<button formType="reset">置空</button>
</view>
</form>2、wxss

}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。
wx.request({
url: 'http://localhost:8080/lg/wechat/add',
data: {
openid: openid,
userpassword: userpassword,
name: name,
sex: app.sex,
tel: tel,
email: email,
vip: app.vip,
},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）
Page({
data: {
industryarr: [],
industryindex: 0,
statusarr: [],
statusindex: 0,
jobarr: [],
jobindex: 0,
},
onLoad: function () {
this.fetchData()
},
fetchData: function () {
this.setData({
industryarr: ["请选择","男", "女"],
statusarr: ["是否注册vip会员","是", "否"],
})
},
// bindPickerChange1: function (e){
// var sex = e.detail.value;
// console.log(sex)
// if(sex==1){
// var app=getApp()
// app.sex='男'
// }else{
// var app = getApp()
// app.sex = '女'
// }
// },
// bindPickerChange2: function (e) {
// var vip = e.detail.value;
// console.log(vip)
// if(vip==1){
// var app=getApp()
// app.vip='是'
// }else{
// var app = getApp()
// app.vip = '否'
// }
// },
bindPickerChange: function (e) { //下拉选择
const eindex = e.detail.value;
//onsole.log(industryarr[e.detail.value])
const name = e.currentTarget.dataset.pickername;
console.log(name)
// this.setData(Object.assign({},this.data,{name:eindex}))
switch (name) {
case 'industry':
var app=getApp()
app.sex = this.data.industryarr[eindex]
console.log(app.sex)
this.setData({
industryindex: eindex
})
case 'status':
var app = getApp()
app.vip = this.data.statusarr[eindex]
console.log(app.vip)
this.setData({
statusindex: eindex
})
break;
case 'job':
this.setData({
jobindex: eindex
})
break;
default:
return
}
},
formSubmit(e) {
var name = e.detail.value.name;
var tel = e.detail.value.tel;
var email = e.detail.value.email;
var userpassword = e.detail.value.password;
console.log('form发生了submit事件，携带数据为：', name, tel, email)
wx.login({
success: function (res) {
var code1 = res.code
var app = getApp()
var appid1 = app.globalData.appid
var secret1 = app.globalData.secret
console.log('获取的code', code1, appid1, secret1)
var ul = 'https://api.weixin.qq.com/sns/jscode2session?appid=' + appid1 + '&secret=' + secret1 + '&js_code=' + code1 + '&grant_type=authorization_code'
wx.request({
url: ul,
method: 'GET',
success: function (e) {
var openid = e.data.openid
console.log('获取登录身份的唯一openid', openid)
// wx.setStorageSync('openid', openid)
//wx.setStorageSync('name', name)
wx.request({
url: 'http://localhost:8080/lg/wechat/add',
data: {
openid: openid,
userpassword: userpassword,
name: name,
sex: app.sex,
tel: tel,
email: email,
vip: app.vip,
},
//method:'POST',
success: function (res) {
const mess=res.data
if (res.data){
console.log("fhgdshxcbxcbxcbcxbxcbxcfj")
wx.showToast({
title: '注册成功',
icon:'success',
})
}else{
wx.showModal({
title: '温馨提示',
content: '您已注册过，请不要重复注册',
success: function (res) {
if (res.confirm) {
wx.navigateTo({
url: '../../pages/login/login',
})
} else if (res.cancel) {
wx.navigateTo({
url: '../../pages/hotel/hotel'
})
}
}
})
}
}
})
}
})
}
})
},
})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，打下自行下载。
package org.lg.controller;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.lg.entity.user;
import org.lg.entity.wcuser;
import org.lg.service.roomlistService;
import org.lg.service.roomtypesService;
import org.lg.service.wcuserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import com.fasterxml.jackson.databind.util.JSONPObject;
import net.sf.json.JSON;
import net.sf.json.JSONObject;
@Controller
@RequestMapping("wechat")
public class wechatController {
@Autowired
public wcuserService wcservice;
@Autowired
public roomlistService roomlistservice;
@Autowired
public roomtypesService roomtypesservice;
//用户注册
@RequestMapping("add")
@ResponseBody
public JSONObject adduser(@RequestParam("openid") String openid,@RequestParam("name") String name,@RequestParam("sex") String sex,@RequestParam("tel") String tel,
@RequestParam("email") String email,@RequestParam("vip") String vip,HttpServletRequest request,
HttpServletResponse response,@RequestParam("userpassword") String userpassword) {
System.out.println(openid+name+sex+tel+email+vip);
Map<String, String> map = new HashMap<String, String>();
if(openid!=null) {
//判断openid在注册的列表中是否存在
wcuser queryopenid = wcservice.queryopenid(openid);
//String openid2 = queryopenid.getOpenid();
if(queryopenid!=null) {
map.put("msg","您已经注册过，请不要重复注册");
JSONObject json = JSONObject.fromObject(map);
return json;
}else{
wcservice.adduc(openid,name, sex, tel, email, vip,userpassword);
//map.put("status","succ");
map.put("msg","注册成功");
JSONObject json = JSONObject.fromObject(map);
return json;
}
}else {
wcuser wcuser1 = wcservice.queryopenid(openid);
String openid2 = wcuser1.getOpenid();
if(openid2!=null) {
map.put("msg","请不要重复注册");
JSONObject json = JSONObject.fromObject(map);
return json;
}else {
map.put("msg","完善信息");
JSONObject json = JSONObject.fromObject(map);
return json;
}
}
}
}5、数据库的那些方法和接口就不写了，重点是小程序的前段和后端的交互。
