介绍

springboot整合微信支付V3使用JSAPI下单全流程,无调用第三方封装易读(完整源码)可开箱享用 目前由于项目需要搞了一个微信支付功能是用于微信小程序端的,时间比较赶看了很久微信官方文档和很多百度的博客一头雾水,怎么搞从哪里搞无头绪! 要么是微信文档太官方各种加密解密太繁琐,要么是像IJPay等优秀开源项目封装太厉害不知如何排查问题!故此抓掉头发总结各大博主经验和微信官方文档,呕心沥血搞出如下适用于微信V3支付JSAPI下单的代码,可供各路大佬享用!注释完整,源码完整,张贴即可上车

软件架构

springboot httpClient lombok

安装教程

  1. 拉下源码
  2. 修改 wxpay_v3.properties 文件内相关参数都有说明
  3. 完善代码中的 TODO 进行自己需求的数据层操作逻辑
  4. 启动项目
  5. 访问获取证书序列号接口 localhost:10086/app/getMchSerialNo
  6. 取出接口返回的证书编号,添加到wxpay_v3.properties 内的v3.mchSerialNo
  7. 按照接口顺序 给前端接口地址进行调用,后端的所有业务就结束了

使用说明

  1. 获取证书序列号更改配置
  2. 通过code换取openid
  3. 使用openid和自己生成的唯一订单号调用微信支付下单接口获得会话ID给前端返回参数
  4. 前端调用获取支付参数接口拿到支付参数唤起微信支付
  5. 支付成功微信回调callback接口,支付流程结束 访问博客地址看更多教程
