前言
提示:SpringBoot集成支付宝沙箱支付简单版 后续可根据实际情况结合其它功能
一、注册支付宝沙箱
直达链接:https://open.alipay.com/develop/sandbox/app
二、使用步骤
1.引入pom文件
<!-- 支付宝支付依赖 -->
<dependency>
<groupId>com.alipay.sdk</groupId>
<artifactId>alipay-sdk-java</artifactId>
<version>4.31.56.ALL</version>
</dependency>
2.配置yml
代码如下(示例):
alipay:
app-id: APPID
private-key: 你的私有密钥(应用私钥)
alipay-public-key: 公有密钥(支付宝公钥)
server-url: https://openapi-sandbox.dl.alipaydev.com/gateway.do
charset: utf-8
sign-type: RSA2
notify-url: http://mkcaa9.natappfree.cc/alipay/notify(填写你的地址+/alipay/notify)
return-url: http://mkcaa9.natappfree.cc/alipay/returnUrl(支付成功回调的地址)
私有密钥和公有密钥在开发信息下公钥模式查看,地址不懂得先看3配置地址映射
3.配置地址映射 最好映射一下本地地址 可以公共访问

双击启动start.bat
三、Java类
