SpringBoot对接支付宝支付API（沙箱环境）
支付宝开放平台：https://open.alipay.com/
支付流程介绍
该图描述了消费者和商户【开发者】服务器和支付宝服务间的请求流程，可以看到用户是通过商户的服务器进行发送支付请求，再由消费者输入相关用户登录信息和支付信息【该流程商户服务器无法干预和监听】，用户和支付宝方的结果会由支付宝服务器通知回商户服务器，商户服务器可以编写对应的逻辑去处理。
获取相关支付秘钥信息
1、首先登陆支付宝开放平台，然后进入管理中心
登录后点击该服务，进入后可以查看到属于自己的沙箱测试账号和一些公钥私钥、商户appid等信息
支付宝开放平台还提供了一些工具和DEMO：
页面拉到中间可以下载示例（这里的手机网站支付下载下来是jsp的）。

电脑网站支付
1、引入相关依赖
com.alipay.sdk
alipay-sdk-java
4.17.5.ALL
com.alipay.sdk
alipay-easysdk
2.1.2
org.apache.commons
commons-lang3
3.3.2
2、在resources目录下创建static文件夹，存在静态html、js、css等等文件
error_url.html
支付宝支付接口
支付失败
notify_url.html
支付宝支付接口测试
通知页面
return_url.html
支付宝支付接口测试
支付成功
3、相关Java代码

}扫码支付
扫码支付，指用户打开支付宝钱包中的“扫一扫”功能，扫描商家展示在某收银场景下的二维码并进行支付的模式。该模式适用于线下实体店支付、面对面支付等场景。
业务流程：
使用步骤：
- 收银员在商家收银系统操作生成支付宝订单，并生成二维码；
- 用户登录支付宝钱包，点击首页“付款-扫码付”或直接点击“扫一扫”，进入扫一扫界面；
- 用户扫收银员提供的二维码，核对金额，确认支付；
- 用户付款后商家收银系统会拿到支付成功或者失败的结果。
产品特点：
- 用户仅出示手机扫码即可完成付款，方便快捷；
- 资金实时到账，无现金流压力。
基本上我们开发常用的也就是一个生成二维码的预创建订单接口，一个取消，一个退款，一个支付成功后的回调接口（有些接口是通用接口，我们上面电脑网站支付已经演示，这里就不再演示）
1、引入相关的依赖
