1、进入支付宝开放平台
https://openhome.alipay.com
2、进入沙箱
2.1 点击启用公钥
点击查看：
3、Java集成沙箱支付
3.1 在pom.xml文件中添加依赖
<!--支付宝依赖 --> <dependency> <groupId>com.alipay.sdk</groupId> <artifactId>alipay-easysdk</artifactId> <version>2.2.0</version> </dependency> <dependency> <groupId>com.alipay.sdk</groupId> <artifactId>alipay-sdk-java</artifactId> <version>4.22.113.ALL</version> </dependency>
3.2 在 application.yml 文件中配置
alipay: appId: appPrivateKey: alipayPublicKey: notifyUrl: 3.3 alipay的java配置：AplipayConfig.java
package com.shijiu.config;import com.alipay.easysdk.factory.Factory;import com.alipay.easysdk.kernel.Config;import lombok.Data;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.stereotype.Component;import javax.annotation.PostConstruct;/** * @Author * @Date Created in 2023/5/5 15:06 * @DESCRIPTION: * @Version V1.0 */@Data@Component//读取yml文件中alipay 开头的配置@ConfigurationProperties(prefix = "alipay")public class AliPayConfig { private String appId; private String appPrivateKey; private String alipayPublicKey; private String notifyUrl; @PostConstruct public void init() { // 设置参数（全局只需设置一次） Config config = new Config(); config.protocol = "https"; config.gatewayHost = "openapi.alipaydev.com"; config.signType = "RSA2"; config.appId = this.appId; config.merchantPrivateKey = this.appPrivateKey; config.alipayPublicKey = this.alipayPublicKey; config.notifyUrl = this.notifyUrl; Factory.setOptions(config); System.out.println("=======支付宝SDK初始化成功======="); }} 3.4 **注意：在拦截器里面加上 忽略alipay接口的配置，这很重要！**
3.5 新建一个AliPayController.java
package com.shijiu.controller;import cn.hutool.core.date.DatePattern;import cn.hutool.core.date.DateUtil;import com.alipay.easysdk.factory.Factory;import com.alipay.easysdk.payment.page.models.AlipayTradePagePayResponse;import com.shijiu.common.Result;import com.shijiu.config.AliPayConfig;import com.shijiu.dao.mapper.ShopOrderMapper;import com.shijiu.pojo.AliPay;import com.shijiu.pojo.ShopOrder;import org.joda.time.DateTime;import org.springframework.transaction.annotation.Transactional;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import java.net.URLEncoder;import com.alipay.api.AlipayApiException;import com.alipay.api.AlipayClient;import com.alipay.api.DefaultAlipayClient;import com.alipay.api.request.AlipayTradePagePayRequest;import com.alipay.easysdk.factory.Factory;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.time.LocalDateTime;import java.util.Date;import java.util.HashMap;import java.util.Map;/** * @Author * @Date Created in 2023/5/5 15:23 * @DESCRIPTION: * @Version V1.0 */@RestController@RequestMapping("alipay")@Transactional(rollbackFor = Exception.class)public class AliPayController { @Resource AliPayConfig aliPayConfig; @Resource private ShopOrderMapper shopOrderMapper; private static final String GATEWAY_URL ="https://openapi.alipaydev.com/gateway.do"; private static final String FORMAT ="JSON"; private static final String CHARSET ="utf-8"; private static final String SIGN_TYPE ="RSA2"; @GetMapping("/pay") // &subject=xxx&traceNo=xxx&totalAmount=xxx public void pay(AliPay aliPay, HttpServletResponse httpResponse) throws Exception { AlipayClient alipayClient = new DefaultAlipayClient(GATEWAY_URL, aliPayConfig.getAppId(), aliPayConfig.getAppPrivateKey(), FORMAT, CHARSET, aliPayConfig.getAlipayPublicKey(), SIGN_TYPE); AlipayTradePagePayRequest request = new AlipayTradePagePayRequest(); request.setNotifyUrl(aliPayConfig.getNotifyUrl()); request.setBizContent("{\"out_trade_no\":\"" + aliPay.getTraceNo() + "\"," + "\"total_amount\":\"" + aliPay.getTotalAmount() + "\"," + "\"subject\":\"" + aliPay.getSubject() + "\"," + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}"); String form = ""; try { // 调用SDK生成表单 form = alipayClient.pageExecute(request).getBody(); } catch (AlipayApiException e) { e.printStackTrace(); } httpResponse.setContentType("text/html;charset=" + CHARSET); // 直接将完整的表单html输出到页面 httpResponse.getWriter().write(form); httpResponse.getWriter().flush(); httpResponse.getWriter().close(); } @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 tradeNo = params.get("out_trade_no"); String gmtPayment = params.get("gmt_payment"); String alipayTradeNo = params.get("trade_no"); // 支付宝验签 if (Factory.Payment.Common().verifyNotify(params)) { // 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")); // 更新订单未已支付 ShopOrder order = new ShopOrder(); order.setId(tradeNo); order.setStatus("1"); Date payTime = DateUtil.parse(gmtPayment, "yyyy-MM-dd HH:mm:ss"); order.setZhhifuTime(payTime); shopOrderMapper.updateById(order); } } return "success"; }}3.6 新建 AliPay.java 参数
package com.shijiu.pojo;import lombok.Data;/** * @Author * @Date Created in 2023/5/5 15:26 * @DESCRIPTION: * @Version V1.0 */@Datapublic class AliPay { private String traceNo; private double totalAmount; private String subject; private String alipayTraceNo;}前端vue 代码：(重点)
handleEdit(row) { this.$confirm('确认支付？, 是否继续?', '删除打卡信息?', { confirmButtonText: '确定', cancelButtonText: '取消', type: 'warning' }).then(() => { window.open(`http://localhost:8888/alipay/pay?subject=${row.orderName}&traceNo=${row.id}&totalAmount=${row.prince}`) this.$message.success('付款成功') this.load() }).catch(() => { this.$message({ type: 'info', message: '已取消付款' }) this.load() }) },3.7 接口测试
然后我们访问URL进行测试，测试的url格式：
http://localhost:8888/alipay/pay?subject=测试商品&traceNo= 666&totalAmount=1000
3.8 内网穿透：https://natapp.cn/
配置免费的隧道，端口：8888：（你项目中的地址端口号）
3.9 新建文本文档 (启动内网穿透工具)：
内容为下列内容。修改格式为 .bat
每次启动回调地址都不同！！！
3.10 回调地址：（如果一次不行，就多重新启动start.bat ,并更新yml文件中的回调地址）
触发回调函数：
看下方的:
3.11 支付结果：（示例：227）
已支付
