springboot整合微信App支付以及支付宝App支付

1. 分别导入项目依赖

         <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.30</version>
        </dependency>
        <dependency>
            <groupId>com.github.wechatpay-apiv3</groupId>
            <artifactId>wechatpay-java</artifactId>
            <version>0.2.17</version>
        </dependency>
          <dependency>
            <groupId>com.alipay.sdk</groupId>
            <artifactId>alipay-sdk-java</artifactId>
            <version>4.40.272.ALL</version>
        </dependency>

2.创建微信支付配置类(WxPayConfig)，以及支付宝配置类(AliYunPayConfig)

2.1.WxPayConfig

package com.medical.config;

    private String mchId = "1718689836";
    private String apiKey;

    private String domain = "https://api.mch.weixin.qq.com/v3/pay/";

    private String path;

    @Bean("config")
    public Config getConfig() {
        // 获取当前项目路径
        if (path == null) {
            path = loadPath();
        }
        // 使用微信支付公钥的RSA配置构建器
        return new RSAPublicKeyConfig.Builder()
                .merchantId(mchId)
                .privateKeyFromPath(path + privateKeyPath)
                .publicKeyFromPath(path + publicKeyPath)
                .publicKeyId(publicKeyId)
                .merchantSerialNumber(serialNumber)
                .apiV3Key(apiV3Key)
                .build();
    }



    private String loadPath() {

         path = System.getProperty("user.dir") + "/src/main/resources";
        File file = new File(path);
        if (!file.exists()) {
            path = System.getProperty("user.dir") + "/medical-server/src/main/resources";
        }
        return path;
    }
}

2.2 AliYunPayConfig

        }
        return path;
    }

}

3.微信App支付实现

    @Override
    public Map<String, Object> wxAppPay(String outTradeNo) throws ServiceException {
        OrderInfo orderInfo = orderService.getBeanByOrderNo(outTradeNo);
        if (orderInfo == null) {
            throw new ServiceException("订单不存在");
        }

        BigDecimal payAmount = orderInfo.getPayAmount();
        // 将金额转换为分
        BigDecimal multiply = payAmount.multiply(new BigDecimal("100"));
        // 转换成整型
        Integer intValue = multiply.intValue();
        Integer number = orderInfo.getNumber();
        // 总价
        Integer total = intValue * number;
        // 订单描述
        String packageName = orderInfo.getPackageName();
        // 构建service
        AppServiceExtension service = new AppServiceExtension.Builder().config(config).build();
        // request.setXxx(val)设置所需参数，具体参数可见Request定义
        PrepayRequest request = new PrepayRequest();
        Amount amount = new Amount();
        amount.setTotal(total); // 单位分
        amount.setCurrency("CNY");
        request.setAmount(amount);
        request.setOutTradeNo(outTradeNo);
        request.setDescription(packageName);
        request.setNotifyUrl(wxPayConfig.getNotifyUrl());
        request.setAppid(wxPayConfig.getAppId());
        request.setMchid(wxPayConfig.getMchId());
        request.setNotifyUrl(wxPayConfig.getNotifyUrl());

        // 调用下单方法，得到应答
        PrepayWithRequestPaymentResponse paymentResponse = service.prepayWithRequestPayment(request);

        // 组装App支付参数信息
        Map<String, Object> appPayParams = new HashMap<>();
        appPayParams.put("appid", wxPayConfig.getAppId());
        appPayParams.put("mchid", wxPayConfig.getMchId());
        appPayParams.put("partner", paymentResponse.getPartnerId());
        appPayParams.put("prepayid", paymentResponse.getPrepayId());
        appPayParams.put("package", "Sign=WXPay");
        appPayParams.put("noncestr", paymentResponse.getNonceStr());
        appPayParams.put("timestamp", paymentResponse.getTimestamp());
        appPayParams.put("sign", paymentResponse.getSign());
        return appPayParams;
    }

4.支付宝App支付实现

    @Override
    public Map<String, Object> alipayAppPay(String orderNo) throws ServiceException {
        try {
            OrderInfo orderInfo = orderService.getBeanByOrderNo(orderNo);
            if (orderInfo == null) {
                throw new ServiceException("订单不存在");
            }

            BigDecimal payAmount = orderInfo.getPayAmount();
            // 将金额转换为元 1元=100分

            Integer number = orderInfo.getNumber();
            // 总价
            BigDecimal multiply = payAmount.multiply(new BigDecimal(number.toString()));
            String total = multiply.toString();
            // 订单描述
            String packageName = orderInfo.getPackageName();

            // 构造请求参数以调用接口
            AlipayTradeAppPayRequest request = new AlipayTradeAppPayRequest();
            AlipayTradeAppPayModel model = new AlipayTradeAppPayModel();
            // 设置商户订单号
            model.setOutTradeNo(orderNo);
            // 设置订单总金额
            model.setTotalAmount(total);
            // 设置订单标题
            model.setSubject(packageName);
            // 设置产品码
            model.setProductCode("QUICK_MSECURITY_PAY");
            // 设置订单绝对超时时间，格式为yyyy-MM-dd HH:mm:ss 日历类
            //  model.setTimeExpire("2016-12-31 10:05:00");
            request.setBizModel(model);
            request.setNotifyUrl(aliYunPayConfig.getNotifyUrl());
            // 调用接口，获取支付结果
            AlipayTradeAppPayResponse response = alipayClient.sdkExecute(request);
            String orderStr = response.getBody();
            boolean success = response.isSuccess();

            Map<String, Object> map = new HashMap<>();
            map.put("orderStr", orderStr);
            return map;
        } catch (Exception e) {
            throw new ServiceException("支付宝支付失败", e);
        }
    }
