订单搜索

• admin的controller层创建OrderController类，并且添加条件搜索方法
• OrderController.java

package com.sky.controller.admin;

import com.sky.dto.OrdersPageQueryDTO;
import com.sky.result.PageResult;
import com.sky.result.Result;
import com.sky.service.OrderService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController("adminOrderController")
@Api(tags = "订单管理接口")
@RequestMapping("/admin/order")
@Slf4j
public class OrderController {

    @Autowired
    private OrderService orderService;

    /**
     * 订单搜索
     * @param ordersPageQueryDTO
     * @return
     */
    @GetMapping("/conditionSearch")
    @ApiOperation("订单搜索")
    public Result<PageResult> conditionSearch(OrdersPageQueryDTO ordersPageQueryDTO){
        log.info("订单搜索:{}",ordersPageQueryDTO);
        PageResult pageResult = orderService.conditionSearch(ordersPageQueryDTO);
        return Result.success(pageResult);
    }
}

• 在OrderService中添加相应方法，并且在实现类中实现
• OrderServiceImpl.java

    @Override
    public PageResult conditionSearch(OrdersPageQueryDTO ordersPageQueryDTO) {
        PageHelper.startPage(ordersPageQueryDTO.getPage(),ordersPageQueryDTO.getPageSize());
        Page<Orders> page = orderMapper.pageQuery(ordersPageQueryDTO);
        List<OrderVO> orderVOList = getOrderVOList(page);
        return new PageResult(page.getTotal(),orderVOList);
    }

    private List<OrderVO> getOrderVOList(Page<Orders> page) {
        List<OrderVO> orderVOList = new ArrayList<>();

        List<Orders> ordersList= page.getResult();
        if(ordersList != null && ordersList.size() > 0){
            for(Orders orders : ordersList){
                OrderVO orderVO = new OrderVO();
                BeanUtils.copyProperties(orders,orderVO);
                orderVO.setOrderDishes(getOrderDishs(orders));
                orderVOList.add(orderVO);
            }
        }
        return orderVOList;
    }

    private String getOrderDishs(Orders orders) {
        // 查询订单菜品详情信息（订单中的菜品和数量）
        List<OrderDetail> orderDetailList = orderDetailMapper.getByOrderId(orders.getId());

        // 将每一条订单菜品信息拼接为字符串（格式：宫保鸡丁*3；）
        List<String> orderDishList = orderDetailList.stream().map(x -> {
            String orderDish = x.getName() + "*" + x.getNumber() + ";";
            return orderDish;
        }).collect(Collectors.toList());

        // 将该订单对应的所有菜品信息拼接在一起
        return String.join("", orderDishList);
    }

各个状态的订单数量统计

• admin的controller层OrderController类，添加条件订单数量统计方法
• OrderController.java

    /**
     * 订单数量统计
     * @return
     */
    @GetMapping("/statistics")
    @ApiOperation("订单数量统计")
    public Result<OrderStatisticsVO> statistics(){
        log.info("订单数量统计");
        OrderStatisticsVO orderStatisticsVO = orderService.statistics();
        return Result.success(orderStatisticsVO);
    }

• 在OrderService中添加相应方法，并且在实现类中实现
• OrderServiceImpl.java

    public OrderStatisticsVO statistics() {
        OrderStatisticsVO orderStatisticsVO = new OrderStatisticsVO();
        OrdersPageQueryDTO ordersPageQueryDTO = new OrdersPageQueryDTO();
        ordersPageQueryDTO.setStatus(Orders.TO_BE_CONFIRMED);
        orderStatisticsVO.setToBeConfirmed(orderMapper.pageQuery(ordersPageQueryDTO).getResult().size());
        ordersPageQueryDTO.setStatus(Orders.CONFIRMED);
        orderStatisticsVO.setConfirmed(orderMapper.pageQuery(ordersPageQueryDTO).getResult().size());
        ordersPageQueryDTO.setStatus(Orders.DELIVERY_IN_PROGRESS);
        orderStatisticsVO.setDeliveryInProgress(orderMapper.pageQuery(ordersPageQueryDTO).getResult().size());
        return orderStatisticsVO;
    }

• 发现问题:在获取page后，使用getTotal返回值一直为0，猜测可能是pageHelper的配置问题，所以使用先获取了result再获取sizie的方法

        // 订单只有存在且状态为2（待接单）才可以拒单
        if (ordersDB == null || !ordersDB.getStatus().equals(Orders.TO_BE_CONFIRMED)) {
            throw new OrderBusinessException(MessageConstant.ORDER_STATUS_ERROR);
        }
        Orders orders = new Orders();
        orders.setStatus(Orders.CANCELLED);
        orders.setId(ordersRejectionDTO.getId());

        orderMapper.update(orders);
    }

        return Result.success();
    }

        if (ordersDB == null || !ordersDB.getStatus().equals(Orders.CONFIRMED)) {
            throw new OrderBusinessException(MessageConstant.ORDER_STATUS_ERROR);
        }

        Orders orders = new Orders();
        orders.setId(ordersDB.getId());

        orders.setStatus(Orders.DELIVERY_IN_PROGRESS);

        orderMapper.update(orders);
    }

        orders.setDeliveryTime(LocalDateTime.now());

        orderMapper.update(orders);
    }

优化用户下单

• 配置外卖商家店铺地址和百度地图的AK：
• application.yml

  shop:
    address: 青海省西宁市城北区宁大路235号青海大学
  baidu:
    ak: nbNi7uwUlppkzYC2pXsQafERrglnCf4G

• 改造OrderServiceImpl，注入上面的配置项，并且在OrderServiceImpl中提供校验方法：
• OrderServiceImpl.java

    @Value("${sky.shop.address}")
    private String shopAddress;

    @Value("${sky.baidu.ak}")
    private String ak;

    /**
     * 检查客户的收货地址是否超出配送范围
     * @param address
     */
    private void checkOutOfRange(String address) {
        Map map = new HashMap();
        map.put("address",shopAddress);
        map.put("output","json");
        map.put("ak",ak);

        //获取店铺的经纬度坐标
        String shopCoordinate = HttpClientUtil.doGet("https://api.map.baidu.com/geocoding/v3", map);

        JSONObject jsonObject = JSON.parseObject(shopCoordinate);
        if(!jsonObject.getString("status").equals("0")){
            throw new OrderBusinessException("店铺地址解析失败");
        }

        //数据解析
        JSONObject location = jsonObject.getJSONObject("result").getJSONObject("location");
        String lat = location.getString("lat");
        String lng = location.getString("lng");
        //店铺经纬度坐标
        String shopLngLat = lat + "," + lng;

        map.put("address",address);
        //获取用户收货地址的经纬度坐标
        String userCoordinate = HttpClientUtil.doGet("https://api.map.baidu.com/geocoding/v3", map);

        jsonObject = JSON.parseObject(userCoordinate);
        if(!jsonObject.getString("status").equals("0")){
            throw new OrderBusinessException("收货地址解析失败");
        }

        //数据解析
        location = jsonObject.getJSONObject("result").getJSONObject("location");
        lat = location.getString("lat");
        lng = location.getString("lng");
        //用户收货地址经纬度坐标
        String userLngLat = lat + "," + lng;

        map.put("origin",shopLngLat);
        map.put("destination",userLngLat);
        map.put("steps_info","0");

        //路线规划
        String json = HttpClientUtil.doGet("https://api.map.baidu.com/directionlite/v1/driving", map);

        jsonObject = JSON.parseObject(json);
        if(!jsonObject.getString("status").equals("0")){
            throw new OrderBusinessException("配送路线规划失败");
        }

        //数据解析
        JSONObject result = jsonObject.getJSONObject("result");
        JSONArray jsonArray = (JSONArray) result.get("routes");
        Integer distance = (Integer) ((JSONObject) jsonArray.get(0)).get("distance");

        if(distance > 5000){
            //配送距离超过5000米
            throw new OrderBusinessException("超出配送范围");
        }
    }

• 在OrderServiceImpl的submitOrder方法中调用上面的校验方法：

windwos后台启动程序

• 进入需要启动的文件目录下，输入powershell
• 运行Start-Process -WindowStyle hidden 你的程序即可

前后端数据传参的区别(@RequestParam,@PathVariable和@RequestBody)

• @RequestParam

http://localhost:8090/hello?id=2
public String Demo1(@RequestParam String id){
    System.out.println(id);
    return null;
}

• @PathVariable

http://localhost:8090/hello/2
@RequestMapping(value = "/getBook/{id}", method = RequestMethod.GET)
public String getBook(@PathVariable Integer id) {
    System.out.println(id);
    return null;
}

• @RequestBody
• 一般是在请求体中，传递比较多参数时使用，可以实现自动封装，即可以以实体类在controller中作为形参
