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.pay
AlipayTradeAppPayRequest 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");

request.setBizModel(model);
//这里和普通的接口调用不同，使用的是sdkExecute
