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 复制代码 
@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 复制代码 
@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 复制代码 
@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 复制代码 
@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 复制代码 
@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 复制代码 
@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 复制代码 
@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">
    select
        info.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_amount

    from order_info info inner join order_bill bill on info.id = bill.order_id
    where info.customer_id = #{customerId}
      and info.order_no = #{orderNo}
</select>









/**
 * 获取订单支付信息
 * @param orderNo
 * @param customerId
 * @return
 */
@GetMapping("/order/info/getOrderPayVo/{orderNo}/{customerId}")
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 复制代码 
@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;
}








/**

 * @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 复制代码 
@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
    @Override
    public 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 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 RequestParam
        RequestParam requestParam = new RequestParam.Builder()
                .serialNumber(wechatPaySerial)
                .nonce(nonce)
                .signature(signature)
                .timestamp(timestamp)
                .body(requestBody)
                .build();
        
        //3.初始化 NotificationParser
        NotificationParser parser = new NotificationParser(rsaAutoCertificateConfig);
        //4.以支付通知回调为例，验签、解密并转换成 Transaction
        Transaction 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 复制代码 
@Service
public class RabbitService {

    @Autowired
    private RabbitTemplate rabbitTemplate;
    
    //发送消息
    public boolean sendMessage(String exchange,
                               String routingkey,
                               Object message) {
        rabbitTemplate.convertAndSend(exchange,routingkey,message);
        return true;
    }
}
  • 修改nacos配置
发送端
java 复制代码 
//如果支付成功，调用其他方法实现支付后处理逻辑
public void handlePayment(Transaction transaction) {

    //1 更新支付记录，状态修改为 已经支付
    //订单编号

    //根据订单编号查询支付记录
    LambdaQueryWrapper<PaymentInfo> wrapper = new LambdaQueryWrapper<>();
    wrapper.eq(PaymentInfo::getOrderNo,orderNo);
    PaymentInfo paymentInfo = paymentInfoMapper.selectOne(wrapper);
    //如果已经支付，不需要更新
    if(paymentInfo.getPaymentStatus() == 1) {
        return;
    }
    paymentInfo.setPaymentStatus(1);
    paymentInfo.setOrderNo(transaction.getOutTradeNo());
    paymentInfo.setTransactionId(transaction.getTransactionId());
    paymentInfo.setCallbackTime(new Date());
    paymentInfo.setCallbackContent(JSON.toJSONString(transaction));
    paymentInfoMapper.updateById(paymentInfo);

    //2 发送端：发送mq消息，传递 订单编号
    //  接收端：获取订单编号，完成后续处理
    rabbitService.sendMessage(MqConst.EXCHANGE_ORDER,
            MqConst.ROUTING_PAY_SUCCESS,
            orderNo);
}
接收端

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 复制代码 
<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 复制代码 
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 复制代码 
//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 复制代码 
//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 复制代码 
//监听延迟队列
@Component
public class RedisDelayHandle {

    @Autowired
    private RedissonClient redissonClient;

    @Autowired
    private OrderInfoService orderInfoService;

    @PostConstruct
    public 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);
        }
    }
}
