（1）拆单接口
仓库表：不是同一个仓库
在service_order模块
订单实现拆单接口OrderService
List<OrderInfo> orderSplit(Long orderId, String wareSkuMap);
拆单接口实现类OrderServiceImpl
@Override
@Transactional
public List<OrderInfo> orderSplit(Long orderId, String wareSkuMap) {ArrayList<OrderInfo> orderInfoArrayList = new ArrayList<>();/*1. 先获取到原始订单 1072. 将wareSkuMap 转换为我们能操作的对象 [{"wareId":"1","skuIds":["2","10"]},{"wareId":"2","skuIds":["3"]}]方案一：class Param{private String wareId;private List<String> skuIds;}方案二：看做一个Map mpa.put("wareId",value); map.put("skuIds",value)3. 创建一个新的子订单 108 109 。。。4. 给子订单赋值5. 保存子订单到数据库6. 修改原始订单的状态7. 测试*///获取父订单OrderInfo orderInfoOrigin = getOrderInfoById(orderId);List<Map> maps = JSON.parseArray(wareSkuMap, Map.class);if (maps != null) {for (Map map : maps) {String wareId = (String) map.get("wareId");List<String> skuIds = (List<String>) map.get("skuIds");OrderInfo subOrderInfo = new OrderInfo();// 属性拷贝BeanUtils.copyProperties(orderInfoOrigin, subOrderInfo);// 防止主键冲突subOrderInfo.setId(null);//设置付订单idsubOrderInfo.setParentOrderId(orderId);// 赋值仓库IdsubOrderInfo.setWareId(wareId);// 计算子订单的金额: 必须有订单明细// 获取到子订单明细// 声明一个集合来存储子订单明细ArrayList<OrderDetail> orderDetails = new ArrayList<>();//获取父订单商品总明细List<OrderDetail> orderDetailList = orderInfoOrigin.getOrderDetailList();// 表示主主订单明细中获取到子订单的明细if (orderDetailList != null && orderDetailList.size() > 0) {for (OrderDetail orderDetail : orderDetailList) {// 获取子订单明细的商品Idfor (String skuId : skuIds) {//对比是否是当前仓库的商品，就收集if (Long.parseLong(skuId) == orderDetail.getSkuId().longValue()) {// 将订单明细添加到集合orderDetails.add(orderDetail);}}}}subOrderInfo.setOrderDetailList(orderDetails);// 计算总金额subOrderInfo.sumTotalAmount();// 保存子订单 submitOrdser（subOrderInfo）saveOrderInfo(subOrderInfo);// 将子订单添加到集合中！orderInfoArrayList.add(subOrderInfo);}}// 修改原始订单的状态updateOrderStatus(orderId, ProcessStatus.SPLIT);return orderInfoArrayList;
}
拆单接口控制器:OrderApiController：
/*** 拆单业务* @param request* @return*/
@RequestMapping("orderSplit")
public String orderSplit(HttpServletRequest request){String orderId = request.getParameter("orderId");String wareSkuMap = request.getParameter("wareSkuMap");// 拆单：获取到的子订单集合List<OrderInfo> subOrderInfoList = orderService.orderSplit(Long.parseLong(orderId),wareSkuMap);// 声明一个存储map的集合ArrayList<Map> mapArrayList = new ArrayList<>();// 生成子订单集合for (OrderInfo orderInfo : subOrderInfoList) {Map map = orderService.initWareOrder(orderInfo);// 添加到集合中！mapArrayList.add(map);}return JSON.toJSONString(mapArrayList);
}
前面已经写了：
实现类
多了两条子订单
库存系统表：
订单任务
订单任务详情
（2）取消订单业务补充关闭支付记录
用户没有点击扫码支付，不会调用支付宝的接口，这个时候订单超时后直接关闭订单就行了，当点击扫码支付后，会调用支付宝接口这个时候就会生成PaymentInfo对象，这个时候超时了，还需要关闭支付记录
此时如果用户扫码了，但是没有支付，订单超时了，这个时候还需要关闭支付宝交易记录
关闭订单流程图：
在处理超时订单里：添加代码
在MqConst中添加常量
/*** 关闭交易*/
public static final String EXCHANGE_DIRECT_PAYMENT_CLOSE = "exchange.direct.payment.close";
public static final String ROUTING_PAYMENT_CLOSE = "payment.close";
//队列
public static final String QUEUE_PAYMENT_CLOSE = "queue.payment.close";
根据业务进行发送1或2,2是有支付记录
在取消订单实现类中发送消息关闭交易
更改接口
2是有支付记录，才发送消息
@Override
public void execExpiredOrder(Long orderId) {// orderInfoupdateOrderStatus(orderId, ProcessStatus.CLOSED);rabbitService.sendMessage(MqConst.EXCHANGE_DIRECT_PAYMENT_CLOSE, MqConst.ROUTING_PAYMENT_CLOSE, orderId);
}
service-payment模块接收消息
编写消费者
package com.atguigu.gmall.payment.receiver;@Component
public class PaymentReceiver {@Autowiredprivate PaymentService paymentService;@SneakyThrows@RabbitListener(bindings = @QueueBinding(value = @Queue(value = MqConst.QUEUE_PAYMENT_CLOSE,durable = "true"),exchange = @Exchange(value = MqConst.EXCHANGE_DIRECT_PAYMENT_CLOSE),key = {MqConst.ROUTING_PAYMENT_CLOSE}))public void closePayment(Long orderId , Message message, Channel channel){if (null != orderId){// 关闭交易paymentService.closePayment(orderId);}// 手动ackchannel.basicAck(message.getMessageProperties().getDeliveryTag(),false);}
}
编写关闭交易记录接口与实现类
PaymentService
/*** 关闭过期交易记录* @param orderId*/
void closePayment(Long orderId);
@Override
public void closePayment(Long orderId) {// 设置关闭交易记录的条件 118QueryWrapper<PaymentInfo> paymentInfoQueryWrapper = new QueryWrapper<>();paymentInfoQueryWrapper.eq("order_id",orderId);// 如果当前的交易记录不存在，则不更新交易记录Integer count = paymentInfoMapper.selectCount(paymentInfoQueryWrapper);if (null == count || count.intValue()==0) return;// 在关闭支付宝交易之前。还需要关闭paymentInfoPaymentInfo paymentInfo = new PaymentInfo();paymentInfo.setPaymentStatus(PaymentStatus.ClOSED.name());paymentInfoMapper.update(paymentInfo,paymentInfoQueryWrapper);}
提交订单超时后会关闭订单
（3）支付宝关闭交易
AlipayService接口
/**** 关闭交易* @param orderId* @return*/
Boolean closePay(Long orderId);
编写实现类
@SneakyThrows
@Override
public Boolean closePay(Long orderId) {OrderInfo orderInfo = orderFeignClient.getOrderInfo(orderId);AlipayTradeCloseRequest request = new AlipayTradeCloseRequest();HashMap<String, Object> map = new HashMap<>();// map.put("trade_no",paymentInfo.getTradeNo()); // 从paymentInfo 中获取！map.put("out_trade_no",orderInfo.getOutTradeNo());map.put("operator_id","YX01");request.setBizContent(JSON.toJSONString(map));AlipayTradeCloseResponse response = alipayClient.execute(request);if(response.isSuccess()){System.out.println("调用成功");return true;} else {System.out.println("调用失败");return false;}
}
编写控制器AlipayController :
http://localhost:8205/api/payment/alipay/closePay/25
// 根据订单Id关闭订单
@GetMapping("closePay/{orderId}")
@ResponseBody
public Boolean closePay(@PathVariable Long orderId){Boolean aBoolean = alipayService.closePay(orderId);return aBoolean;
}
（4）查询支付交易记录
编写接口：AlipayService
/*** 根据订单查询是否支付成功！* @param orderId* @return*/
Boolean checkPayment(Long orderId);
编写实现类
@SneakyThrows
@Override
public Boolean checkPayment(Long orderId) {// 根据订单Id 查询订单信息OrderInfo orderInfo = orderFeignClient.getOrderInfo(orderId);AlipayTradeQueryRequest request = new AlipayTradeQueryRequest();HashMap<String, Object> map = new HashMap<>();map.put("out_trade_no",orderInfo.getOutTradeNo());// 根据out_trade_no 查询交易记录request.setBizContent(JSON.toJSONString(map));AlipayTradeQueryResponse response = alipayClient.execute(request);if(response.isSuccess()){System.out.println("调用成功")；return true;} else {System.out.println("调用失败")return false;}
}
编写控制器
// 查看是否有交易记录
@RequestMapping("checkPayment/{orderId}")
@ResponseBody
public Boolean checkPayment(@PathVariable Long orderId){// 调用退款接口boolean flag = alipayService.checkPayment(orderId);return flag;
}
没有支付返回false
支付后返回true
在AlipayController 添加查询PaymentInfo 数据接口
查询支付记录
@GetMapping("getPaymentInfo/{outTradeNo}")
@ResponseBody
public PaymentInfo getPaymentInfo(@PathVariable String outTradeNo){PaymentInfo paymentInfo = paymentService.getPaymentInfo(outTradeNo, PaymentType.ALIPAY.name());if (null!=paymentInfo){return paymentInfo;}return null;
}
（5）PaymentFeignClient 远程接口
创建service-payment-client
package com.atguigu.gmall.payment.client;
@FeignClient(value = "service-payment",fallback = PaymentDegradeFeignClient.class)
public interface PaymentFeignClient {@GetMapping("api/payment/alipay/closePay/{orderId}")Boolean closePay(@PathVariable Long orderId);@GetMapping("api/payment/alipay/checkPayment/{orderId}")Boolean checkPayment(@PathVariable Long orderId);@GetMapping("api/payment/alipay/getPaymentInfo/{outTradeNo}")PaymentInfo getPaymentInfo(@PathVariable String outTradeNo);}
PaymentDegradeFeignClient实现类
@Component
public class PaymentDegradeFeignClient implements PaymentFeignClient {@Override<dependency><groupId>com.atguigu.gmall</groupId><artifactId>service-payment-client</artifactId><version>1.0</version>
</dependency>public Boolean closePay(Long orderId) {return null;}@Overridepublic Boolean checkPayment(Long orderId) {return null;}@Overridepublic PaymentInfo getPaymentInfo(String outTradeNo) {return null;}}
（6）整合关闭过期订单
在订单service-order项目中添加依赖
<dependency><groupId>com.atguigu.gmall</groupId><artifactId>service-payment-client</artifactId><version>1.0</version>
</dependency>
OrderReceiver 整合代码
接口：OrderService
/*** 更新过期订单* @param orderId* @param flag*/
void execExpiredOrder(Long orderId,String flag);
@Override
public void execExpiredOrder(Long orderId,String flag) {// 调用方法 状态updateOrderStatus(orderId,ProcessStatus.CLOSED);//2代表支付宝有交易记录就是扫码了没有支付if ("2".equals(flag)){// 发送消息队列，关闭支付宝的交易记录。rabbitService.sendMessage(MqConst.EXCHANGE_DIRECT_PAYMENT_CLOSE,MqConst.ROUTING_PAYMENT_CLOSE,orderId);}
}
@Autowired
private RabbitService rabbitService;@Autowired
private PaymentFeignClient paymentFeignClient;
// 监听消息
@SneakyThrows
@RabbitListener(queues = MqConst.QUEUE_ORDER_CANCEL)
public void orderCancel(Long orderId, Message message, Channel channel){try {// 判断订单id 是否存在！if (orderId!=null){// 根据订单Id 查询订单对象OrderInfo orderInfo = orderService.getById(orderId);// 判断if(orderInfo!=null && "UNPAID".equals(orderInfo.getOrderStatus()) && "UNPAID".equals(orderInfo.getProcessStatus())){// 关闭过期订单！ 还需要关闭对应的 paymentInfo ，还有alipay.// orderService.execExpiredOrder(orderId);// 查询支付记录信息paymentInfo -远程调用是否存在！PaymentInfo paymentInfo = paymentFeignClient.getPaymentInfo(orderInfo.getOutTradeNo());// 判断 用户点击了扫码支付if(paymentInfo!=null && "UNPAID".equals(paymentInfo.getPaymentStatus())){// 查看是否有支付宝交易记录！Boolean flag = paymentFeignClient.checkPayment(orderId);// 判断if (flag){// flag = true , 有支付宝记录// 调用关闭接口！ 扫码未支付这样才能关闭成功！Boolean result = paymentFeignClient.closePay(orderId);// 判断if (result){// result = true; 关闭成功！未付款！需要关闭orderInfo， paymentInfo，AlipayorderService.execExpiredOrder(orderId,"2");}else {// result = false; 表示付款！// 说明已经付款了！ 正常付款成功都会走异步通知！}}else {// 没有交易记录，不需要关闭支付！ 需要关闭orderInfo， paymentInfo//关闭订单，关闭支付记录orderService.execExpiredOrder(orderId,"2");}}else {// 只关闭订单orderInfo！orderService.execExpiredOrder(orderId,"1");}}}} catch (Exception e) {// 写入日志...e.printStackTrace();}// 手动确认channel.basicAck(message.getMessageProperties().getDeliveryTag(),false);
}
不进行支付
