Springboot集成支付宝沙盒支付

阅读需 3 分钟

1.开发前准备

1.1 支付宝沙盒配置

1.1.1 注册支付宝开发者账号,进入开发者控制台

https://openhome.alipay.com/platform/developerIndex.htm

1.1.2 沙盒入口

https://open.alipay.com/develop/sandbox/app

将上面的APPID、支付宝网关消息、应用密钥和支付宝公钥保管好,下面会使用到。

2 集成沙盒支付

2.1 再pom.xml文件中添加下面依赖

<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>4.22.110.ALL</version>
</dependency>

2.2 在application.yml 里面进行配置:

alipay:
appId: APPID
appPrivateKey: 应用私钥
alipayPublicKey: 支付宝公钥
notifyUrl: 后面再填

2.3 创建AlipayConfig.java

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;

@Data
@Component
@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(全局只需要设置一次)
Config config = new Config();
config.protocol = "https";
config.gatewayHost = "openapi-sandbox.dl.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=====");
}
}

2.4 支付接口

2.4.1 新建一个AliPay.java

import lombok.Data;

@Data
public class AliPay {
private String traceNo;
private double totalAmount;
private String subject;
private String alipayTraceNo;
}

2.4.2 新建一个AliPayController.java

import cn.hutool.json.JSONObject;
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 com.example.learnrabbitmq.config.AliPayConfig;
import com.example.learnrabbitmq.model.AliPay;
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 javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import java.util.HashMap;
import java.util.Map;

/**

* Date: 2023/10/10 13:02
*/
@RestController
@RequestMapping("alipay")
@Transactional(rollbackFor = Exception.class)
public class AliPayController {

@Resource
AliPayConfig aliPayConfig;

private static final String GATEWAY_URL ="https://openapi-sandbox.dl.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")
public void pay(AliPay aliPay, HttpServletResponse httpResponse) throws IOException {
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 {
form = alipayClient.pageExecute(request).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();
}


2.5 接口测试

测试的url格式:

http://localhost:你的端口/alipay/pay?subject=任意填&traceNo=任意填&totalAmount=填数字
age:http://localhost:8081/alipay/pay?subject=test&traceNo=666&totalAmount=1000

成功截图:

然后使用沙盒账号中的买家账号进行登录

成功界面:

2.6 回调接口

在AliPayController.java添加以下代码

@PostMapping("/notify")
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"));

}
}
return "success";
}
}

使用该接口必须在外网的条件下,这里作者使用内外穿透来实现。

内外穿透:https://natapp.cn/

观看该文档:https://natapp.cn/article/natapp_newbie

本地端口改为自己的端口。

得到地址之后在application.yml中的notifyUrl去添加。

再次调用pay接口,支付完成后后台会打印出以下内容。

这就是全篇内容了,感谢您的阅读,菠萝屋祝你愉快的度过每一天。
