1、支付宝开放平台操作
我们需要做内网穿透，推荐使用 ngrok | API Gateway, Kubernetes Ingress, Webhook Gateway
详细接口参考API - 开放平台
进入 控制台首页 - 开放平台，开通沙箱环境
支付宝公钥，和你的秘钥点击查看就能看到
2、Springboot项目集成
1、添加依赖
添加支付宝sdk依赖和糊涂工具包
<dependency> <groupId>com.alipay.sdk</groupId> <artifactId>alipay-sdk-java</artifactId> <version>4.22.110.ALL</version> </dependency> <dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <version>5.8.25</version> </dependency>2、配置文件添加
alipay: # 应用ID app-id: 你的APPID # 商户私钥 merchant-private-key: 你的私钥 # 支付宝公钥 alipay-public-key: 支付宝公钥 # 网关地址 gateway-url: https://openapi.alipay.com/gateway.do # 回调地址（需公网可访问） notify-url: https://your-domain.com/alipay/notify return-url: https://your-domain.com/alipay/return # 签名方式 sign-type: RSA2 charset: UTF-8 format: JSON3、代码实现
配置类

package com.jha.springcloudlearn.controller; import com.alipay.api.AlipayApiException; import com.alipay.api.AlipayClient; import com.alipay.api.internal.util.AlipaySignature; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Component; import java.util.Map; @Component public class AlipayNotifyHandler { @Value("${alipay.alipay-public-key}") private String alipayPublicKey; @Value("${alipay.charset}") private String charset; @Value("${alipay.sign-type}") private String signType; /** * 验证支付宝回调的签名 */ public boolean verifySignature(Map<String, String> params) { try { return AlipaySignature.rsaCheckV1( params, alipayPublicKey, charset, signType ); } catch (AlipayApiException e) { return false; } } }这样就能接入了支付宝了
3、测试
运行我们的项目，然后使用接口工具进行测试
1、获取表单
得到的出参就是一个form表单，正常来说由前端那边去做接受然后处理，这边我们就自己把他放到html中去做后续支付操作
2、构建html
<!-- 将返回的HTML代码保存为 .html 文件 --> <!DOCTYPE html> <html> <head> <title>支付宝支付</title> </head> <body> <!-- 返回的form表单复制到下面，并运行即可 --> </body> </html>3、支付流程
打开html之后，出现如下页面
这里扫码支付暂时是不行的，因为我们使用的是沙箱，所以使用账号登录
账号在如下图所示位置
输入账户密码之后，跳转到另一个支付页面
输入支付密码之后，进行确认付款即可
然后就是跳转到成功支付的页面，然后再调用我们的回调函数
这样支付宝就接入成功了，后续可以加入自己个性化的东西，如订单操作等
