乐尚代驾十订单支付seata、rabbitmq异步消息、redisson延迟队列

devtools/2024/11/13 16:45:13/

账单信息

  • 司机结束代驾之后，生成账单（包含账单信息和分账信息）
  • 司机发送账单给乘客
  • 乘客获取账单之后，进行支付

获取账单信息

order_bill表记录的账单信息，我们直接获取即可

java">@Operation(summary = "根据订单id获取实际账单信息")
@GetMapping("/getOrderBillInfo/{orderId}")
public Result<OrderBillVo> getOrderBillInfo(@PathVariable Long orderId) {return Result.ok(orderInfoService.getOrderBillInfo(orderId));
}@Override
public OrderBillVo getOrderBillInfo(Long orderId) {LambdaQueryWrapper<OrderBill> wrapper = new LambdaQueryWrapper<>();wrapper.eq(OrderBill::getOrderId,orderId);OrderBill orderBill = orderBillMapper.selectOne(wrapper);OrderBillVo orderBillVo = new OrderBillVo();BeanUtils.copyProperties(orderBill,orderBillVo);return orderBillVo;
}/*** 根据订单id获取实际账单信息* @param orderId* @return*/
@GetMapping("/order/info/getOrderBillInfo/{orderId}")
Result<OrderBillVo> getOrderBillInfo(@PathVariable("orderId") Long orderId);

获取分账信息

java">@Operation(summary = "根据订单id获取实际分账信息")
@GetMapping("/getOrderProfitsharing/{orderId}")
public Result<OrderProfitsharingVo> getOrderProfitsharing(@PathVariable Long orderId) {return Result.ok(orderInfoService.getOrderProfitsharing(orderId));
}@Override
public OrderProfitsharingVo getOrderProfitsharing(Long orderId) {LambdaQueryWrapper<OrderProfitsharing> wrapper = new LambdaQueryWrapper<>();wrapper.eq(OrderProfitsharing::getOrderId,orderId);OrderProfitsharing orderProfitsharing = orderProfitsharingMapper.selectOne(wrapper);OrderProfitsharingVo orderProfitsharingVo = new OrderProfitsharingVo();BeanUtils.copyProperties(orderProfitsharing,orderProfitsharingVo);return orderProfitsharingVo;
}/*** 根据订单id获取实际分账信息* @param orderId* @return*/
@GetMapping("/order/info/getOrderProfitsharing/{orderId}")
Result<OrderProfitsharingVo> getOrderProfitsharing(@PathVariable("orderId") Long orderId);

司机端获取账单信息

java">@Operation(summary = "获取订单账单详细信息")
@GuiguLogin
@GetMapping("/getOrderInfo/{orderId}")
public Result<OrderInfoVo> getOrderInfo(@PathVariable Long orderId) {Long driverId = AuthContextHolder.getUserId();return Result.ok(orderService.getOrderInfo(orderId, driverId));
}@Override
public OrderInfoVo getOrderInfo(Long orderId, Long driverId) {OrderInfo orderInfo = orderInfoFeignClient.getOrderInfo(orderId).getData();if(orderInfo.getDriverId() != driverId) {throw new GuiguException(ResultCodeEnum.ILLEGAL_REQUEST);}//获取账单和分账数据，封装到vo里面OrderBillVo orderBillVo = null;OrderProfitsharingVo orderProfitsharingVo = null;//判断，是否结束代驾if(orderInfo.getStatus() >= OrderStatus.END_SERVICE.getStatus()) {//账单信息orderBillVo = orderInfoFeignClient.getOrderBillInfo(orderId).getData();//分账信息orderProfitsharingVo = orderInfoFeignClient.getOrderProfitsharing(orderId).getData();}OrderInfoVo orderInfoVo = new OrderInfoVo();orderInfoVo.setOrderId(orderId);BeanUtils.copyProperties(orderInfo,orderInfoVo);orderInfoVo.setOrderBillVo(orderBillVo);orderInfoVo.setOrderProfitsharingVo(orderProfitsharingVo);return orderInfoVo;
}

司机发送账单

  • 发送账单就是更新订单状态，未支付
java">@Operation(summary = "发送账单信息")
@GetMapping("/sendOrderBillInfo/{orderId}/{driverId}")
Result<Boolean> sendOrderBillInfo(@PathVariable Long orderId, @PathVariable Long driverId) {return Result.ok(orderInfoService.sendOrderBillInfo(orderId, driverId));
}@Override
public Boolean sendOrderBillInfo(Long orderId, Long driverId) {//更新订单信息LambdaQueryWrapper<OrderInfo> queryWrapper = new LambdaQueryWrapper<>();queryWrapper.eq(OrderInfo::getId, orderId);queryWrapper.eq(OrderInfo::getDriverId, driverId);//更新字段OrderInfo updateOrderInfo = new OrderInfo();updateOrderInfo.setStatus(OrderStatus.UNPAID.getStatus());//只能更新自己的订单int row = orderInfoMapper.update(updateOrderInfo, queryWrapper);if(row == 1) {return true;} else {throw new GuiguException(ResultCodeEnum.UPDATE_ERROR);}
}/*** 司机发送账单信息* @param orderId* @param driverId* @return*/
@GetMapping("/order/info/sendOrderBillInfo/{orderId}/{driverId}")
Result<Boolean> sendOrderBillInfo(@PathVariable("orderId") Long orderId, @PathVariable("driverId") Long driverId);@Operation(summary = "司机发送账单信息")
@GuiguLogin
@GetMapping("/sendOrderBillInfo/{orderId}")
public Result<Boolean> sendOrderBillInfo(@PathVariable Long orderId) {Long driverId = AuthContextHolder.getUserId();return Result.ok(orderService.sendOrderBillInfo(orderId, driverId));
}@Override
public Boolean sendOrderBillInfo(Long orderId, Long driverId) {return orderInfoFeignClient.sendOrderBillInfo(orderId, driverId).getData();
}

乘客获取账单

java">@Override
public OrderInfoVo getOrderInfo(Long orderId, Long customerId) {OrderInfo orderInfo = orderInfoFeignClient.getOrderInfo(orderId).getData();//判断if(orderInfo.getCustomerId() != customerId) {throw new GuiguException(ResultCodeEnum.ILLEGAL_REQUEST);}//获取司机信息DriverInfoVo driverInfoVo = null;Long driverId = orderInfo.getDriverId();if(driverId != null) {driverInfoVo = driverInfoFeignClient.getDriverInfo(driverId).getData();}//获取账单信息OrderBillVo orderBillVo = null;if(orderInfo.getStatus() >= OrderStatus.UNPAID.getStatus()) {orderBillVo = orderInfoFeignClient.getOrderBillInfo(orderId).getData();}OrderInfoVo orderInfoVo = new OrderInfoVo();orderInfoVo.setOrderId(orderId);BeanUtils.copyProperties(orderInfo,orderInfoVo);orderInfoVo.setOrderBillVo(orderBillVo);orderInfoVo.setDriverInfoVo(driverInfoVo);return orderInfoVo;
}

微信支付

获取乘客openid

java">@Operation(summary = "获取客户OpenId")
@GetMapping("/getCustomerOpenId/{customerId}")
public Result<String> getCustomerOpenId(@PathVariable Long customerId) {return Result.ok(customerInfoService.getCustomerOpenId(customerId));
}@Override
public String getCustomerOpenId(Long customerId) {LambdaQueryWrapper<CustomerInfo> wrapper = new LambdaQueryWrapper<>();wrapper.eq(CustomerInfo::getId,customerId);CustomerInfo customerInfo = customerInfoMapper.selectOne(wrapper);return customerInfo.getWxOpenId();
}/*** 获取客户OpenId* @param customerId* @return*/
@GetMapping("/customer/info/getCustomerOpenId/{customerId}")
Result<String> getCustomerOpenId(@PathVariable("customerId") Long customerId);

获取司机openid

  • 与获取乘客openid基本一致

获取订单支付信息

java">@Operation(summary = "获取订单支付信息")
@GetMapping("/getOrderPayVo/{orderNo}/{customerId}")
public Result<OrderPayVo> getOrderPayVo(@PathVariable String orderNo, @PathVariable Long customerId) {return Result.ok(orderInfoService.getOrderPayVo(orderNo, customerId));
}@Override
public OrderPayVo getOrderPayVo(String orderNo, Long customerId) {OrderPayVo orderPayVo = orderInfoMapper.selectOrderPayVo(orderNo,customerId);if(orderPayVo != null) {String content = orderPayVo.getStartLocation() + " 到 "+orderPayVo.getEndLocation();orderPayVo.setContent(content);}return orderPayVo;
}<select id="selectOrderPayVo" resultType="com.atguigu.daijia.model.vo.order.OrderPayVo">selectinfo.id as order_id,info.customer_id,info.driver_id,info.order_no,info.start_location,info.end_location,info.status,bill.pay_amount,bill.coupon_amountfrom order_info info inner join order_bill bill on info.id = bill.order_idwhere info.customer_id = #{customerId}and info.order_no = #{orderNo}

Result<OrderPayVo> getOrderPayVo(@PathVariable("orderNo") String orderNo, @PathVariable("customerId") Long customerId);

申请并绑定微信支付


微信支付商户平台：https://pay.weixin.qq.com/index.php/core/home/login

对于商家来说，想要开通微信支付，必须要去“微信支付商户平台”注册，然后把需要的资料提交上去，经过审核通过，你就开通了微信支付功能。

企业申请资料：

1、营业执照：彩色扫描件或数码照片

2、组织机构代码证：彩色扫描件或数码照片，若已三证合一，则无需提供

3、对公银行账户：包含开户行省市信息，开户账号

4、法人身份证：彩色扫描件或数码照片

如果想要在网站或者小程序上面使用微信支付，还要在微信公众平台上面关联你自己的微信商户账号。前提是你的微信开发者账号必须是企业身份，个人身份的开发者账号是无法调用微信支付API的。

支付密钥和数字证书


因为调用微信支付平台的API接口，必须要用到支付密钥和数字证书，这些参数在微信支付商户平台都可以获取。

查询支付状态

  • 判断微信支付是否成功，有两种方式，就是以上两种红字
  • 微信支付成功/失败就会回调我们的接作
  • 收到调用之后我们就可以继续接下来的操作
  • 用消息队列保证数据的最终一致性，在支付成功后我们后续还有很多的操作，如果把所有的操作全部成功再向用户进行返回，那就太慢了，如果支付成功，我们就先向用户返回结果，并向消息队列发送关键信息用于后续的操作
根据订单编号查询支付状态
java">@Operation(summary = "支付状态查询")
@GetMapping("/queryPayStatus/{orderNo}")
public Result queryPayStatus(@PathVariable String orderNo) {return Result.ok(wxPayService.queryPayStatus(orderNo));
}//查询支付状态
@Override
public Boolean queryPayStatus(String orderNo) {//1 创建微信操作对象JsapiServiceExtension service =new JsapiServiceExtension.Builder().config(rsaAutoCertificateConfig).build();//2 封装查询支付状态需要参数QueryOrderByOutTradeNoRequest queryRequest = new QueryOrderByOutTradeNoRequest();queryRequest.setMchid(wxPayV3Properties.getMerchantId());queryRequest.setOutTradeNo(orderNo);//3 调用微信操作对象里面方法实现查询操作Transaction transaction = service.queryOrderByOutTradeNo(queryRequest);//4 查询返回结果，根据结果判断if(transaction != null&& transaction.getTradeState() == Transaction.TradeStateEnum.SUCCESS) {//5 如果支付成功，调用其他方法实现支付后处理逻辑this.handlePayment(transaction);return true;}return false;
}/*** 支付状态查询* @param orderNo* @return*/
@GetMapping("/payment/wxPay/queryPayStatus/{orderNo}")
Result<Boolean> queryPayStatus(@PathVariable("orderNo") String orderNo);@Operation(summary = "支付状态查询")
@GuiguLogin
@GetMapping("/queryPayStatus/{orderNo}")
public Result<Boolean> queryPayStatus(@PathVariable String orderNo) {return Result.ok(orderService.queryPayStatus(orderNo));
}@Override
public Boolean queryPayStatus(String orderNo) {return wxPayFeignClient.queryPayStatus(orderNo).getData();
}
微信支付成功回调接口
java">@Operation(summary = "微信支付异步通知接口")
@PostMapping("/notify")
public Map<String,Object> notify(HttpServletRequest request) {try {wxPayService.wxnotify(request);//返回成功Map<String,Object> result = new HashMap<>();result.put("code", "SUCCESS");result.put("message", "成功");return result;} catch (Exception e) {e.printStackTrace();}//返回失败Map<String,Object> result = new HashMap<>();result.put("code", "FAIL");result.put("message", "失败");return result;
}//微信支付成功后，进行的回调@Overridepublic void wxnotify(HttpServletRequest request) {
//1.回调通知的验签与解密//从request头信息获取参数//HTTP 头 Wechatpay-Signature// HTTP 头 Wechatpay-Nonce//HTTP 头 Wechatpay-Timestamp//HTTP 头 Wechatpay-Serial//HTTP 头 Wechatpay-Signature-Type//HTTP 请求体 body。切记使用原始报文，不要用 JSON 对象序列化后的字符串，避免验签的 body 和原文不一致。String wechatPaySerial = request.getHeader("Wechatpay-Serial");String nonce = request.getHeader("Wechatpay-Nonce");String timestamp = request.getHeader("Wechatpay-Timestamp");String signature = request.getHeader("Wechatpay-Signature");String requestBody = RequestUtils.readData(request);//2.构造 RequestParamRequestParam requestParam = new RequestParam.Builder().serialNumber(wechatPaySerial).nonce(nonce).signature(signature).timestamp(timestamp).body(requestBody).build();//3.初始化 NotificationParserNotificationParser parser = new NotificationParser(rsaAutoCertificateConfig);//4.以支付通知回调为例，验签、解密并转换成 TransactionTransaction transaction = parser.parse(requestParam, Transaction.class);if(null != transaction && transaction.getTradeState() == Transaction.TradeStateEnum.SUCCESS) {//5.处理支付业务this.handlePayment(transaction);}}
内网穿透配置

  • 还可以把项目部署到腾讯云、华为云等来解决这个问题
  • 测试的时候我们没有域名，就可以使用内网穿透的工具

这里使用的工具是ngrok.cc

支付成功后续处理

封装RabbitMQ
java">@Service
public class RabbitService {@Autowiredprivate RabbitTemplate rabbitTemplate;//发送消息public boolean sendMessage(String exchange,String routingkey,Object message) {rabbitTemplate.convertAndSend(exchange,routingkey,message);return true;}
}

seata实现分布式事务

订单支付成功后，订单状态更新、获取订单系统奖励、系统奖励打入司机账户都是通过远程调用来实现的，我们就在这儿使用seata分布式事务

java"><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-seata</artifactId>
</dependency>
<dependency><groupId>io.seata</groupId><artifactId>seata-spring-boot-starter</artifactId><version>1.7.1</version>
</dependency>seata.tx-service-group=tingshu-tx-group
seata.service.vgroup-mapping.tingshu-tx-group=default
seata.service.grouplist.default=127.0.0.1:8091// 在事务的入口添加@GlobalTransactional
// 其他的小事务依然使用@Transactional

乘客下单功能

  • 乘客登录之后，选择代驾开始和结束地址，之后乘客呼叫代驾
  • 乘客呼叫代驾之后，等待司机接单
  • 但是，如果在乘客呼叫代驾之后15分钟之后，如果还是没有司机接单，订单自动取消，如果15分钟以内有司机接单，完成代驾过程
  • 总结：15分钟没有司机接单，自动取消订单
  • 总体思路：使用延迟队列消息实现订单到时间自动取消功能
  • 有很多种方式：

第一种 使用RabbitMQ里面TTL和死信队列实现

第二种 在RabbitMQ安装延迟队列实现

  • 就是装个插件，在这个队列中的消息不能被消费，只有延时时间到了才能被消费，第三种 使用Redisson实现

使用RabbitMQ里面TTL和死信队列实现

  • TTL：Time To Live，消息存活时间


发送端：发送消息，设置存活时间10s

接收端：发送完成之后，10s以内如果从队列获取发送过来消息，操作结束

​ 如果超过10s消息没有被消费，消息超时了，无法被消费，成为死信

  • 死信队列：无法被消费的消息


– 超过存活时间没有被消费的消息

– 消息端拒绝接收，不能放回队列里面

– 队列最大长度

使用Redisson实现

  • 利用redissonClient 发送延迟消息
java">redissonClient.getBlockingDeque(): 创建一个阻塞队列redissonClient.getDelayedQueue(): 获取延迟队列delayedQueue.offer(): 向队列中存储数据blockingDeque.take(): 从队列中获取数据

java">//乘客下单
@Override
public Long saveOrderInfo(OrderInfoForm orderInfoForm) {//order_info添加订单数据OrderInfo orderInfo = new OrderInfo();BeanUtils.copyProperties(orderInfoForm,orderInfo);//订单号String orderNo = UUID.randomUUID().toString().replaceAll("-","");orderInfo.setOrderNo(orderNo);//订单状态orderInfo.setStatus(OrderStatus.WAITING_ACCEPT.getStatus());orderInfoMapper.insert(orderInfo);//生成订单之后，发送延迟消息this.sendDelayMessage(orderInfo.getId());//记录日志this.log(orderInfo.getId(),orderInfo.getStatus());//向redis添加标识//接单标识，标识不存在了说明不在等待接单状态了redisTemplate.opsForValue().set(RedisConstant.ORDER_ACCEPT_MARK,"0", RedisConstant.ORDER_ACCEPT_MARK_EXPIRES_TIME, TimeUnit.MINUTES);return orderInfo.getId();
}
  • 编写发送延迟消息的方法
javascript">//生成订单之后，发送延迟消息
private void sendDelayMessage(Long orderId) {try{//1 创建队列RBlockingQueue<Object> blockingDueue = redissonClient.getBlockingQueue("queue_cancel");//2 把创建队列放到延迟队列里面RDelayedQueue<Object> delayedQueue = redissonClient.getDelayedQueue(blockingDueue);//3 发送消息到延迟队列里面//设置过期时间delayedQueue.offer(orderId.toString(),15,TimeUnit.MINUTES);}catch (Exception e) {e.printStackTrace();throw new GuiguException(ResultCodeEnum.DATA_ERROR);}
}
  • 监听延迟队列消息
java">//监听延迟队列
@Component
public class RedisDelayHandle {@Autowiredprivate RedissonClient redissonClient;@Autowiredprivate OrderInfoService orderInfoService;@PostConstructpublic void listener() {new Thread(()->{// while true 实现一直监听while(true) {//获取延迟队列里面阻塞队列RBlockingQueue<String> blockingQueue = redissonClient.getBlockingQueue("queue_cancel");//从队列获取消息try {String orderId = blockingQueue.take();//取消订单if(StringUtils.hasText(orderId)) {//调用方法取消订单orderInfoService.orderCancel(Long.parseLong(orderId));}} catch (InterruptedException e) {throw new RuntimeException(e);}}}).start();}
}//调用方法取消订单
@Override
public void orderCancel(long orderId) {//orderId查询订单信息OrderInfo orderInfo = orderInfoMapper.selectById(orderId);//判断if(orderInfo.getStatus()==OrderStatus.WAITING_ACCEPT.getStatus()) {//修改订单状态：取消状态orderInfo.setStatus(OrderStatus.CANCEL_ORDER.getStatus());int rows = orderInfoMapper.updateById(orderInfo);if(rows == 1) {//删除接单标识redisTemplate.delete(RedisConstant.ORDER_ACCEPT_MARK);}}
}
