springboot对接微信支付的完整流程(附前后端代码)_第1张图片 

springboot对接微信支付的完整流程(附前后端代码)_第2张图片

对接的完整流程如下

首先是配置

gzh.appid=公众号appid
wxPay.mchId=商户号
wxPay.key=支付密钥
wxPay.notifyUrl=域名回调地址

常量:

/**微信支付统一下单接口*/
    public static final String unifiedOrderUrl = "https://api.mch.weixin.qq.com/pay/unifiedorder";
 
 
    public static String SUCCESSxml = " \r\n" +

前端页面:




    
    Title
    


    body: 
outTradeNo:

openid:

 访问前端页面记得加依赖:


            org.springframework.boot
            spring-boot-starter-thymeleaf
        

访问页面需要写控制类:

package com.jch.mng.controller;
 
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
 
import javax.servlet.http.HttpServletResponse;
 
/**
 * Created by xxs on 2021/7/31 12:29
 *
 * @Description
 * @Version 2.9
 */
@Controller
public class TestPageController {
 
 
    @RequestMapping("/wxPayTest")
    public String test(HttpServletResponse response)  {
        return "wxPay";
    }
}

运行项目访问。

附:名词解释

商户号:微信支付分配的商户号。支付审核通过后,申请人邮箱会收到腾讯下发的开户邮件, 邮件中包含商户平台的账号、密码等重要信息。

appid:商户通过微信管理后台,申请服务号、订阅号、小程序或APP应用成功之后,微信会为每个应用分配一个唯一标识id。

openid:用户在公众号内的身份标识,一旦确认,不会再变;同一用户在不同公众号拥有不同的openid。商户后台系统通过登录授权、支付通知、查询订单等API可获取到用户的openid。主要用途是判断同一个用户,对用户发送客服消息、模版消息等。

微信管理后台:微信有很多管理平台,容易混淆,我们主要关注下面三个平台:

1. 微信公众平台 微信公众账号申请入口和管理后台。商户可以在公众平台提交基本资料、业务资料、财务资料申请开通微信支付功能。帐号分类:服务号、订阅号、小程序、企业微信(也叫企业号,类似于企业OA)。

2. 微信商户平台 微信支付相关的商户功能集合,包括参数配置、支付数据查询与统计、在线退款、代金券或立减优惠运营等功能。

3. 微信开放平台 商户APP接入微信支付开放接口的申请入口,通过此平台可申请微信APP支付。

签名:商户后台和微信支付后台根据相同的密钥和算法生成一个结果,用于校验双方身份合法性。签名的算法 由微信支付制定并公开,常用的签名方式有:MD5、SHA1、SHA256、HMAC等。

密钥:作为签名算法中的盐,需要在微信平台及商户业务系统各存一份,要妥善保管。 key设置路径:微信商户平台(http://pay.weixin.qq.com)-->账户设置-->API安全-->密钥设置。
