springboot+支付宝条码支付开发详解

背景：项目原有乐刷聚合支付，无法参加支付宝、微信等支付机构的官方活动

需求：增加原生支付（支付宝条码支付）

方法：

　　一、官方文档：https://docs.open.alipay.com/194/106039

　　二、没有真实企业账号的可以使用沙箱环境：https://docs.open.alipay.com/200/105311

　　三、两种方法实现：

　　　　（一）基于支付宝标准SDK：alipay-sdk-java

　　　　　　1、pom文件中添加SDK依赖

　　　　　　　　地址：https://mvnrepository.com/artifact/com.alipay.sdk/alipay-sdk-java

　　　　　　2、配置支付宝参数

　　　　　　　　在系统常量类里追加（我这里配的是沙箱参数，就直接写在实现类里）

　　　　　　　　

　　　　　　3.实现代码
