Spring task

cron表达式
导入spring task坐标（spring-context已经存在），添加@EnableScheduling注解

订单状态定时处理

新建task包，并且创建OrderTask定时类，添加处理超时订单和处理一直派送中的订单方法
OrderTask.java

package com.sky.task;

import com.sky.entity.Orders;
import com.sky.mapper.OrderMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.time.LocalDateTime;
import java.util.List;

/**
 * 定时任务类，定时处理订单状态
 */
@Component
@Slf4j
public class OrderTask {

    @Autowired
    private OrderMapper orderMapper;

    /**
     * 处理超时订单
     */
    @Scheduled(cron = "0 * * * * ?")//每分钟触发一次
    public void processTimeoutOrder() {
        log.info("定时处理超时订单:{}", LocalDateTime.now());
        LocalDateTime localDateTime = LocalDateTime.now().plusMinutes(-15);
        List<Orders> ordersList = orderMapper.getByStatusAndOrderTimeLT(Orders.PENDING_PAYMENT, localDateTime);
        if (ordersList != null && ordersList.size() > 0) {
            for (Orders orders : ordersList) {
                orders.setStatus(Orders.CANCELLED);
                orders.setCancelReason("订单超时自动取消");
                orders.setCancelTime(LocalDateTime.now());
                orderMapper.update(orders);
            }
        }
    }

    /**
     * 处理一直派送中的订单
     */
    @Scheduled(cron = "0 0 1 * * ?")//每天凌晨一点
    public void processDeliveryOrder(){
        log.info("处理一直派送中的订单:{}",LocalDateTime.now());
        LocalDateTime localDateTime = LocalDateTime.now().plusHours(-1);
        List<Orders> ordersList = orderMapper.getByStatusAndOrderTimeLT(Orders.DELIVERY_IN_PROGRESS, localDateTime);
        if (ordersList != null && ordersList.size() > 0) {
            for (Orders orders : ordersList) {
                orders.setStatus(Orders.COMPLETED);
                orders.setCancelReason("订单超时自动取消");
                orders.setCancelTime(LocalDateTime.now());
                orderMapper.update(orders);
            }
        }

    }
}

来单提醒

因为无法实现支付功能，所以直接在模拟订单支付处修改，而不是支付成功处
OrderServiceImpl.java

    @Override
    public void payment(OrdersPaymentDTO ordersPaymentDTO) {
        //下单时直接根据用户id更新订单状态为已支付
        Long currentId = BaseContext.getCurrentId();
        Orders ordersDB = orderMapper.getByNumber(ordersPaymentDTO.getOrderNumber());
        // 根据订单id更新订单的状态、支付方式、支付状态、结账时间
        Orders orders = Orders.builder()
                .id(ordersDB.getId())
                .userId(currentId)
                .status(Orders.TO_BE_CONFIRMED)
                .payStatus(Orders.PAID)
                .checkoutTime(LocalDateTime.now())
                .build();

        orderMapper.updateByUserId(orders);
        Map map = new HashMap<>();
        map.put("type",1);
        map.put("orderId",ordersDB.getId());
        map.put("content","订单号" + ordersPaymentDTO.getOrderNumber());
        String s = JSON.toJSONString(map);
        webSocketServer.sendToAllClient(s);
    }

客户催单

user controller层添加客户催单方法
OrderController.java

    @GetMapping("/reminder/{id}")
    @ApiOperation("用户催单")
    public Result reminder(@PathVariable Long id){
        orderService.reminder(id);
        log.info("用户催单:{}",id);
        return Result.success();
    }

OrderServiceImpl相应添加并且实现
OrderServiceImpl.java

    @Override
    public void reminder(Long id) {
        // 根据id查询订单
        Orders ordersDB = orderMapper.getByOrderId(id);

        // 校验订单是否存在，并且状态为4
        if (ordersDB == null ) {
            throw new OrderBusinessException(MessageConstant.ORDER_STATUS_ERROR);
        }
        Map map = new HashMap<>();
        map.put("type",2);
        map.put("orderId",id);
        map.put("content","订单号" +  ordersDB.getNumber());
        webSocketServer.sendToAllClient(JSON.toJSONString(map));
    }
