        orderMapper.update(orders);
    }

4. 测试

派送订单

1. OrderController

    /**
     * 派送订单
     * @param id
     * @return
     */
    @PutMapping("/delivery/{id}")
    public Result delivery(@PathVariable("id") Long id) {
        orderService.delivery(id);
        return Result.success();
    }

2. OrderService

    /**
     * 派送订单
     * @param id
     */
    void delivery(Long id);

3. OrderServiceImpl

    /**
     * 派送订单
     * @param id
     */
    @Override
    public void delivery(Long id) {
        // 根据id查询订单
        Orders orderDB = orderMapper.getById(id);
        
        // 校验订单是否存在,并且状态为3
        if(orderDB == null || !orderDB.getStatus().equals(Orders.CONFIRMED)) {
            throw new OrderBusinessException(MessageConstant.ORDER_STATUS_ERROR);
        }
        
        Orders orders = new Orders();
        orders.setId(orderDB.getId());
        // 更新订单状态,状态转为派送中
        orders.setStatus(Orders.DELIVERY_IN_PROGRESS);
        
  

4. 测试

完成订单

1. admin/OrderController

    /**
     * 完成订单
     * @param id
     * @return
     */
    @PutMapping("/complete/{id}")
    @ApiOperation("完成订单")
    public Result complete(@PathVariable("id") Long id) {
        orderService.complete(id);
        return Result.success();
    }

2. OrderService

    /**
     * 完成订单
     * @param id
     */
    void complete(Long id);

3. OrderServiceImpl

    /**
     * 完成订单
     * @param id
     */
    @Override
    public void complete(Long id) {
        // 根据id查询订单
        Orders ordersDB = orderMapper.getById(id);
        
        // 校验订单是否存在,并且状态为4
        if(ordersDB == null || !ordersDB.getStatus().equals(Orders.DELIVERY_IN_PROGRESS)) {
            throw new OrderBusinessException(MessageConstant.ORDER_STATUS_ERROR);
        }
        
        Orders orders = new Orders();
        orders.setId(ordersDB.getId());
        // 更新订单状态,状态转为完成
        orders.setStatus(Orders.COMPLETED);
        orders.setDeliveryTime(LocalDateTime.now());
        
        orderMapper.update(orders);
    }

4. 测试

三、检测收货地址是否超出配送范围

1. 注册百度账号

注册百度账号

2. 登录百度地图开发平台

百度地图开放平台 | 百度地图API SDK | 地图开发

点击“控制台”,注册开发者账号。需要等待百度那边审核,注意不要填错个人信息

3. 创建应用

4. 配置外卖商家店铺地址和百度地图的AK

application-dev.yml

application.yml

5. 更改OrderServiceImpl,注入上面的配置项

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

6. 在OrderServiceImpl中提供校验方法

    /**
     * 检查客户的收获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);
        // 地址解析
        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");
        }
        
        // 数据分析
        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");
        }
    }

7. 在OrderServiceImpl的submitOrder方法中调用地址校验方法

8. 测试
