支付系统设计实现(1)——支付与退款

摘要：支付流程以上是微信支付的流程用户进入选择商品进行购买，在内部结算时生成用户本系统订单待支付状态，此时返回订单信息与支付方式列表用户确认金额无误，并选择支付方式。

以上是微信app支付的流程：

用户进入app选择商品进行购买，在app内部结算时生成用户本系统订单（待支付状态），此时返回订单信息与支付方式列表

用户确认金额无误，并选择支付方式。此时app将订单id与支付方式传给服务器，服务器根据订单金额与支付方式在外部支付系统下单（预支付订单），并给app返回可以唤起响应支付工具的‘支付数据’

app获取到‘支付数据’调用响应支付sdk，此时用户会看见微信支付或支付宝支付的页面，此时用户需要确认支付金额并输入正确的密码

sdk会检查用户的密码信息是否正确并返回支付结果，此时app收到sdk同步通知的支付结果，并提交到服务器，服务器会记录该笔支付的状态，切记不能使用app上传回来的支付结果作为最终的支付结果，不能信任前端数据

外部支付系统在处理完成该笔支付后会回调服务器设置的回调接口，通知服务器该笔支付的最终支付状态
收到通知时需要注意：

同样的通知可能会多次发送给商户系统。商户系统必须能够正确处理重复的通知。

后台通知交互时，如果微信收到商户的应答不符合规范或超时，微信会判定本次通知失败，重新发送通知，直到成功为止，但微信不保证通知最终一定能成功。

在订单状态不明或者没有收到微信支付结果通知的情况下，建议商户主动调用微信支付【查询订单API】确认订单状态。

商户系统对于支付结果通知的内容一定要做签名验证,并校验返回的订单金额是否与商户侧的订单金额一致，防止数据泄漏导致出现“假通知”，造成资金损失。

当收到通知进行处理时，首先检查对应业务数据的状态，判断该通知是否已经处理过，如果没有处理过再进行处理，如果处理过直接返回结果成功。在对业务数据进行状态检查和处理之前，要采用数据锁进行并发控制，以避免函数重入造成的数据混乱。

以上流程时微信与支付宝给出的官方流程，并且也是最标准的流程。但是当外部支付系统并没有微信与支付宝那么优秀的时候，我们的系统就不能按照该流程正常运行下去，下面我说说在使用‘建行支付’时遇到的问题

服务器收不到支付结果的回调

即使主动查询支付状态‘建行支付’依然返回未支付的状态

以上两个问题会引发更复杂的问题

由于没有支付回调，订单状态就不会发送改变用户就会再次支付，造成重复支付的现象

系统没有预料到会出现重复支付也就没有相应的策略去弥补

由于系统并不知道支付已经成功，用户在取消订单的时候就不会收到退款

根据这些线上出现的问题，我们决定进行重构，并深层次的处理整个支付流程！

1.确认支付方式

1.微信App支付
2.支付宝App支付
3.建行支付App支付

2.如何确保支付成功

1.外部支付系统（支付宝）成功后回调通知
2.本系统主动查询外部支付系统订单状态

3.如何避免用户重复支付

1.本系统在发起支付的时候检查‘订单号’是否有已经成功的支付记录
2.本系统在发起支付的时候检查‘订单号’是否有已经提交的支付记录，如果有需要同步查询外部支付系统该订单的支付状态

4.如果用户出现重复支付系统如何处理

1.系统需要定时检查是否有同一个‘订单号’出现多条成功支付的记录，如果有需要保留一笔支付，其余的进行退款处理    

5.数据出现异常怎么办（例如：用户说支付完成，但是订单依然是待支付的状态）

1.所有的支付流程都需要进行数据记录，形成支付流水，这样可以直观的看到用户支付的路径，也方便外部支付系统查询

‘支付’是一次支付的记录，可能包含多个订单的支付金额，因为用户在购买商品生成订单的时候会根据商家拆单

‘支付与订单的隐射’表明该支付中所有的订单信息，每个‘映射’都记录了订单的金额与支付状态，并且重复支付也是发生在该‘映射’上的，因为一个订单智能有一次最终成功支付的记录,最终哪一个映射是有效的由‘是否当前使用’决定，任何时候一个订单只有一个映射有效

‘支付’可能有多条退款记录，退款的总金额不能超过支付金额，并且每一笔退款都需要一个唯一的退款交易号来保证不会重复退款，退款交易号由具体业务系统生成（比如退货，取消订单，重复支付）

所有的退款必须成功

系统需要主动查询支付状态是‘发起支付’，‘app同步通知成功’记录在外部支付系统的支付状态，如果在外部支付系统支付成功，这里需要重新设置支付状态为‘已完成’

支付的外部交易号与退款的退款交易号都是唯一的

为了保证系统的正常工作我们还需要一些定时器来作为最后的防线

1. 支付业务逻辑

public interface IPaymentApplicationService {

/**
 * 创建支付，待支付状态
 * @param orders 订单JSONArray
 * @param paymentAmount 支付金额
 * @param paymentChannel 支付渠道
 * @param paymentType 支付方式
 * @param accountId 账户
 * @param serviceId 服务
 * @param platformId 平台
 * @param hockParams 回传参数
 * @return
 */
PaymentResultDTO createPayment(List orders, BigDecimal paymentAmount, PaymentChannelEnum paymentChannel, PaymentTypeEnum paymentType, String accountId, String serviceId, String platformId,String hockParams) throws InvalidOperationException;

/**
 * app、小程序、H5收到回调
 * @param paymentId 支付id
 * @param isSuccess 是否支付成功
 */
void synchronizedCallback(String paymentId,boolean isSuccess) throws InvalidOperationException, PaymentQueryException, PaymentNotExistException;

/**
 * app、小程序、H5收到回调
 * @param orderIds 本次支付的所有订单id
 * @param isSuccess 是否成功
 */
void synchronizedCallback(Collection orderIds,boolean isSuccess);

/**
 * 服务器端收到回调
 * @param paymentId 支付id
 * @param isSuccess 是否支付成功
 * @param tradeNo 交易号
 */
void asyncCallback(String paymentId,boolean isSuccess,String tradeNo) throws InvalidOperationException;


/**
 * 服务器端收到回调
 * @param outTradeNo 外部交易号
 * @param isSuccess 是否支付成功
 * @param tradeNo 交易号
 */
void asyncCallbackForOutTradeNo(String outTradeNo,boolean isSuccess,String tradeNo);

}

2.退款业务逻辑

public interface IRefundApplicationService {

/**
 * 发起退款
 * @param paymentId 支付id
 * @param sysRefundTradeNo 系统内部退款单号
 * @param refundAmount 退款金额
 * @param refundType 退款类型
 * @param reason 退款理由
 * @return 退款id
 */
void createRefund(String paymentId,String sysRefundTradeNo, BigDecimal refundAmount, RefundTypeEnum refundType, String reason) throws Exception;

/**
 * 针对订单发起退款
 * @param orderId 订单id
 * @param sysRefundTradeNo 系统内部退款单号
 * @param refundAmount 退款金额
 * @param refundType 退款类型
 * @param reason 退款理由
 * @return 退款id
 */
void createRefundByOrder(String orderId,String sysRefundTradeNo, BigDecimal refundAmount, RefundTypeEnum refundType, String reason) throws Exception;

/**
 * 退款
 * @param refund 退款实体
 */
void refund(RefundDO refund) throws InvalidOperationException;

}
