代码开发

application.yml


OrderServiceImpl

改造 OrderServiceImpl,注入上面的配置项

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

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

在 OrderServiceImpl 中提供校验方法

java
/**
     * 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
