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
2. 代码开发

配置外卖商家店铺地址和百度地图的AK:
2.2 OrderServiceImpl
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:
(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");}
