springboot怎么做微信支付（实用干货一步一步教你在SpringBoot集成支付宝手机网站支付）

一：简介

手机网站支付常用于HTML5应用，常见于微信公众号上的应用。手机网站支付文档

手机网站支付的流程图：

1. 用户点击H5应用中的支付按钮
2. 点击支付按钮会请求后台接口，后台接口请求支付宝的支付接口，支付接口会返回一段html代码其中包括一个form表单和一段js代码用于自动提交表单，表单提交后就会自动跳转到支付宝的支付页面(如果手机中装了支付App就去打开APP，如果没有就在网页版支付
3. 支付成功后会调用支付时设置的同步url, 然后跳转到商户的后台系统，一般情况下商户系统会展示一下支付成功，以及购买的商品信息等视图

二：集成步骤

0. 创建应用、配置密钥

集成前需要先创建应用、配置密钥、回调地址等，具体操作请查看Spring Boot入门教程(三十五):支付宝集成-准备工作

1. dependency

2. application.yml

手机网站支付需要支付成功后同步的地址returnUrl，支付成功后跳转到的页面，这个值既可以配在这里也可以在Java代码调用支付宝接口时也可以设置为别的值

7. WebMvcConfiguration

通过访问http://localhost:8080/toPay来跳转到toPay.html页面

@Configuration public class WebMvcConfiguration extends WebMvcConfigurationSupport { @Override protected void addViewControllers(ViewControllerRegistry registry) { registry.addViewController("/toPay").setViewName("toPay"); super.addViewControllers(registry); } }

8. templates

toPay.html

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body style="font-size: 30px"> <form method="post" action="/alipay/wap/alipage"> <h3>购买商品：越南新娘</h3> <h3>价格：20000</h3> <h3>数量：2个</h3> <button style="width: 100%; height: 60px; alignment: center; background: blue" type="submit">支付</button> </form> </body> </html>

wapPaySuccess.html

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>WAP 支付成功，请及时享用！欢迎下次再来</h1> </body> </html>

wapPayFail.html

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h2>WAP 支付失败，请重新支付</h2> </body> </html>

三：运行结果

首先访问去支付页面：http://localhost:8080/toPay
