springboot集成支付宝的支付(easy版)

SpringBoot对接支付宝

需要先注册账号

到支付宝开发者平台创建网页支付应用

启用公钥模式

需要使用到appId和下面的两个秘钥

---

写配置信息的代码

1.引入依赖

        <dependency>

            <groupId>com.alipay.sdk</groupId>

            <artifactId>alipay-easysdk</artifactId>

            <version>2.2.0</version>

        </dependency>

2.写配置

alipay:

  appId: appid

  appPrivateKey: 应用私钥

  alipayPublicKey: 支付宝的公钥

  notifyUrl: 回调地址

3.新建一个alipayConfig类

import com.alipay.easysdk.factory.Factory;

import com.alipay.easysdk.kernel.Config;

import org.springframework.boot.context.properties.ConfigurationProperties;

import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;

@Data

@Component

//拿配置文件里面alipay开头的配置信息

@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=======");

    }

}

4.写接口

    @GetMapping("/pay")

    public String pay(AliPay aliPay) {

        AlipayTradePagePayResponse response;

        try {

            //  发起API调用（以创建当面付收款二维码为例）

            response = Factory.Payment.Page()

                    .pay(URLEncoder.encode(aliPay.getSubject(), "UTF-8"), aliPay.getTraceNo(),String.valueOf(aliPay.getTotalAmount()), "");

        } catch (Exception e) {

            System.err.println("调用遭遇异常，原因：" + e.getMessage());

            throw new RuntimeException(e.getMessage(), e);

        }

        return response.getBody();

    }

//如果设置了拦截器 需要放行该接口

5.设置回调接口

 @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

                //ordersMapper.updateState(tradeNo, "已支付", gmtPayment, alipayTradeNo);

            }

        }

        return "success";

    }
