SpringBoot集成支付宝沙箱支付

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：登录 - 支付宝

二、使用步骤

1.引入pom文件

                            com.alipay.sdk            alipay-sdk-java            4.31.56.ALL        

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

下载 解压 配置

双击启动start.bat

三、Java类

1. AliPayController.Java

1. AliPay.Java

import lombok.Data;@Datapublic class AliPay {    private String traceNo;// 我们自己生成的订单编号    private double totalAmount;// 订单的总金额    private String subject;// 支付的名称    private String alipayTraceNo;}
