这篇文章将为大家详细讲解有关Java如何利用沙箱支付实现电脑扫码支付，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
1、注册支付宝开放平台账号，成为开发者。
地址：https://open.alipay.com/platform/home.htm
2、进入沙箱，进行配置。
3.我们可以看到这个界面
4.后面需要使用的参数
APPID
商户私钥（使用系统默认密钥的公钥模式，点击查看获取）
支付宝公钥
支付宝网关
5、手机上下载沙箱支付宝 （到时候支付用这个支付宝支付）
6、下载好支付宝沙箱版后，登录支付宝提供的账号
1、随手写的一个前台vue界面
2、进入确定订单界面，可以添加商品描述
3、跳转支付界面，利用沙箱支付宝完成支付
4、完成支付
5、跳回自己设置的界面
（我这里利用的是SpringBoot集成的SSM,当然不使用SpringBoot也可以）
