支付宝支付相关代码

①需要在支付宝中签约相关权限

②配置支付宝公私钥

③此处注意，前端金额单位为分，但支付宝的单位为元，此处是支付宝需要注意的地方
支付宝app支付

         //getway变量（网关）,appid（支付宝应用appid），privateKey（私钥）,publicKey(支付宝公钥)AlipayClient client = new DefaultAlipayClient(getway,appid,privateKey, "json","GBK", publicKey, "RSA2");//实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.trade.app.payAlipayTradeAppPayRequest request = new AlipayTradeAppPayRequest();// callbackurl : 支付成功回调地址request.setNotifyUrl(callBackUrl);//SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式(model和biz_content同时存在的情况下取biz_content)。AlipayTradeAppPayModel model = new AlipayTradeAppPayModel();//对一笔交易的具体描述信息。如果是多种商品，请将商品描述字符串累加传给body。model.setBody(payParam.getBody());//商品的标题/交易标题/订单标题/订单关键字等。    model.setSubject(payParam.getSubject());//业务订单号model.setOutTradeNo(payParam.getOrderId());//设置订单超期时间model.setTimeExpire(DateUtil.format(new Date(System.currentTimeMillis() + 1000 * 60 * OutTimeMinute), "yyyy-MM-dd HH:mm:ss"));//支付宝金额（单位元）model.setTotalAmount(payParam.getTotalAmount().divide(new BigDecimal("100"), 2, BigDecimal.ROUND_HALF_UP).toPlainString());model.setProductCode("QUICK_MSECURITY_PAY");log.info("model:{}", JSON.toJSONString(model, true));request.setBizModel(model);//这里和普通的接口调用不同，使用的是sdkExecuteAlipayTradeAppPayResponse response = client.sdkExecute(request);log.info("支付宝下单response={}", response.getBody());if (response.isSuccess()) {//成功后处理的逻辑} else {//失败时处理的逻辑}

支付宝js支付

         //getway变量（网关）,appid（支付宝应用appid），privateKey（私钥）,publicKey(支付宝公钥)AlipayClient client = new DefaultAlipayClient(getway,appid,privateKey, "json","GBK", publicKey, "RSA2");AlipayTradeCreateRequest request = new AlipayTradeCreateRequest();// callbackurl : request.setNotifyUrl(callBackUrl);AlipayTradeCreateModel model = new AlipayTradeCreateModel();model.setBody(payParam.getBody());model.setBuyerId(payParam.getBuyerId());model.setSubject(payParam.getSubject());model.setOutTradeNo(payParam.getOrderId());model.setTimeoutExpress(DateUtil.format(DateUtils.addMinutes(new Date(), 10), "yyyy-MM-dd HH:mm:ss"));//转化交易金额单位为元DecimalFormat df = new DecimalFormat("#0.00");model.setTotalAmount(df.format(payParam.getTotalAmount().divide(new BigDecimal("100"), 2, BigDecimal.ROUND_HALF_UP).toPlainString()));request.setBizModel(model);log.info("model:{}", JSON.toJSONString(model, true));AlipayTradeCreateResponse response = client.pageExecute(request);log.info("支付宝下单response={}", response);if (response.isSuccess()) {//成功后处理的逻辑} else {//失败时处理的逻辑}

支付宝H5支付

         //getway变量（网关）,appid（支付宝应用appid），privateKey（私钥）,publicKey(支付宝公钥)AlipayClient client = new DefaultAlipayClient(getway,appid,privateKey, "json","GBK", publicKey, "RSA2");//该笔订单允许的最晚付款时间//设置请求参数String content = "{\"out_trade_no\":\"" + payParam.getOrderId() + "\","+ "\"total_amount\":\"" + payParam.getTotalAmount().divide(new BigDecimal("100"), 2, BigDecimal.ROUND_HALF_UP).toPlainString() + "\","+ "\"subject\":\"" + payParam.getSubject() + "\","+ "\"timeout_express\":\"" + DateUtil.format(new Date(System.currentTimeMillis() + 1000 * 60 * OutTimeMinute), "yyyy-MM-dd HH:mm:ss") + "\","+ "\"body\":\"" + payParam.getBody() + "\","+ "\"product_code\":\"" + "QUICK_MSECURITY_PAY" + "\"}";AlipayTradeWapPayRequest alipayRequest = new AlipayTradeWapPayRequest();
//            alipayRequest.setReturnUrl(AlipayConfig.return_url);alipayRequest.setNotifyUrl(callBackUrl);alipayRequest.setBizContent(content);//请求AlipayTradeWapPayResponse response = client.pageExecute(alipayRequest);log.info("支付宝下单response={}", response);if (response.isSuccess()) {//成功后处理的逻辑} else {//失败时处理的逻辑}

支付宝订单查询
