登录百度地图开放平台:https://lbsyun.baidu.com/
进入控制台,创建应用,获取AK:
相关接口:
https://lbsyun.baidu.com/index.php?title=webapi/guide/webservice-geocoding
https://lbsyun.baidu.com/index.php?title=webapi/directionlite-v1
配置外卖商家店铺地址和百度地图的AK:
改造OrderServiceImpl,注入上面的配置项:
@Value("${sky.shop.address}")
private String shopAddress;
@Value("${sky.baidu.ak}")
private String ak;
在OrderServiceImpl中提供校验方法:
/**
* 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:
