1 支付流程实现
演示案例
主要参考程序员青戈的视频【支付宝沙箱支付快速集成版】支付宝沙箱支付快速集成版_哔哩哔哩_bilibili
对应的源码在
alipay-demo: 使用支付宝沙箱实现支付功能 - Gitee.com
以下是完整的实现步骤
1.首先导入相关的依赖

}自身实现的接口
创建一个配置文件
alipay.appId=APPID
alipay.appPrivateKey=应用私钥
alipay.alipayPublicKey=支付宝公钥
alipay.notifyUrl=异步发送通知消息的 URL 地址。
alipay.returnUrl=回调地址相关参数的获取方式
请参考 快速接入 - 支付宝文档中心
具体的沙箱参数 沙箱应用 - 开放平台
APPID
支付宝公钥和应用私钥
notifyUrl
需要借助一个内网穿透的工具
这里使用的是natapp
官网：https://natapp.cn/
下载：https://pan.baidu.com/s/1L99Ibawylnck4b4c0NtmXg?pwd=685x
具体的配置可以查看文档
NATAPP1分钟快速新手图文教程 - NATAPP-内网穿透 基于ngrok的国内高速内网映射工具
如何进行内网穿刺
a.配置完免费版的隧道，下载之后，Windows系统进行如下步骤
b.cmd -authtoken= 参数方式运行.
windows ,点击开始->运行->命令行提示符 后进入 natapp.exe的目录
c.运行
natapp -authtoken=9ab6b9040a624f40注意参数输入正确性,不要有多余的空格等!
d.运行成功,都可以得到如下界面:
Tunnel Status Online 代表链接成功
Version 当前客户端版本,如果有新版本,会有提示
Forwarding 当前穿透 网址 或者端口
Web Interface 是本地Web管理界面,可在隧道配置打开或关闭,仅用于web开发测试
Total Connections 总连接数
Avg Conn Time 0.00ms 这里不代表,不代表,不代表 延时,需要注意!
notifyUrl=上图获取的穿透网址+Controller层的接口utl
alipay.returnUrl=回调地址 前端Vue的接口
设置对应的配置类
package com.example.alipay.common;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Data
@Component
@ConfigurationProperties(prefix = "alipay")
public class AlipayConfig {
private String appId;
private String appPrivateKey;
private String alipayPublicKey;
private String notifyUrl;
private String returnUrl;
}对应的Controller接口
@GetMapping("/pay") // &subject=xxx&traceNo=xxx&totalAmount=xxx
public void pay(AliPay aliPay, HttpServletResponse httpResponse) throws Exception {
//创建交易单
// 1. 创建Client，通用SDK提供的Client，负责调用支付宝的API
AlipayClient alipayClient = new DefaultAlipayClient(GATEWAY_URL, aliPayConfig.getAppId(),
aliPayConfig.getAppPrivateKey(), FORMAT, CHARSET, aliPayConfig.getAlipayPublicKey(), SIGN_TYPE);
// 2. 创建 Request并设置Request参数
AlipayTradePagePayRequest request = new AlipayTradePagePayRequest(); // 发送请求的 Request类
request.setNotifyUrl(aliPayConfig.getNotifyUrl());
JSONObject bizContent = new JSONObject();
bizContent.set("out_trade_no", aliPay.getTraceNo()); // 我们自己生成的订单编号
bizContent.set("total_amount", aliPay.getTotalAmount()); // 订单的总金额
bizContent.set("subject", aliPay.getSubject()); // 支付的名称
bizContent.set("product_code", "FAST_INSTANT_TRADE_PAY"); // 固定配置
request.setBizContent(bizContent.toString());
// 执行请求，拿到响应的结果，返回给浏览器
String form = "";
try {
AlipayTradePagePayResponse response = alipayClient.pageExecute(request);
System.out.println(response); // 在控制台输出响应结果
form = response.getBody(); // 调用SDK生成表单
} catch (AlipayApiException e) {
e.printStackTrace();
}
httpResponse.setContentType("text/html;charset=" + CHARSET);
httpResponse.getWriter().write(form);// 直接将完整的表单html输出到页面
httpResponse.getWriter().flush();
httpResponse.getWriter().close();
}如何异步通知商家
主要使用的是回调函数
@PostMapping("/notify") // 注意这里必须是POST接口
public String payNotify(HttpServletRequest request) throws Exception {
if (request.getParameter("trade_status").equals("TRADE_SUCCESS")) {
System.out.println("=========支付宝异步回调========");
Map<String, String> params = new HashMap<>();
Map<String, String[]> requestParams = request.getParameterMap();
for (String name : requestParams.keySet()) {
params.put(name, request.getParameter(name));
// System.out.println(name + " = " + request.getParameter(name));
}
String outTradeNo = params.get("out_trade_no");
String gmtPayment = params.get("gmt_payment");
String alipayTradeNo = params.get("trade_no");
String sign = params.get("sign");
String content = AlipaySignature.getSignCheckContentV1(params);
boolean checkSignature = AlipaySignature.rsa256CheckContent(content, sign, aliPayConfig.getAlipayPublicKey(), "UTF-8"); // 验证签名
// 支付宝验签
if (checkSignature) {
// 验签通过
System.out.println("交易名称: " + params.get("subject"));
System.out.println("交易状态: " + params.get("trade_status"));
System.out.println("支付宝交易凭证号: " + params.get("trade_no"));
System.out.println("商户订单号: " + params.get("out_trade_no"));
System.out.println("交易金额: " + params.get("total_amount"));
System.out.println("买家在支付宝唯一id: " + params.get("buyer_id"));
System.out.println("买家付款时间: " + params.get("gmt_payment"));
System.out.println("买家付款金额: " + params.get("buyer_pay_amount"));
// 查询订单
/**
* 使用 QueryWrapper 查询订单，根据订单号（outTradeNo）从数据库中查找订单。
* 如果订单存在，更新订单信息，包括支付宝交易号（alipayNo）、支付时间（PayTime）和订单状态（State），将订单状态更新为 已支付。
* 最后返回 success，告诉支付宝服务器回调处理成功。
*/
QueryWrapper<Orders> queryWrapper = new QueryWrapper<>();
queryWrapper.eq("order_id", outTradeNo);
Orders orders = ordersMapper.selectOne(queryWrapper);
if (orders != null) {
orders.setAlipayNo(alipayTradeNo);
orders.setPayTime(new Date());
orders.setState("已支付");
ordersMapper.updateById(orders);
}
}
}
return "success";

}注意网关地址，需要修改 GATEWAY_URL 为对应沙箱的支付宝网关地址
访问地址
http://localhost:9090/alipay/pay?subject=%E9%A6%99%E8%95%89&traceNo=202208221661165525068&totalAmount=6.99
支付之后，会返回相应的支付信息
