篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了springboot+支付宝条码支付开发详解相关的知识,希望对你有一定的参考价值。
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
