1、先看一下高德地图WEB API都有哪些内容

2、根据经经纬度查询高德地图省市区数据

/**

*根据经纬度获取省市区

* @param lat

* @return

*/

public static String getCoordinate(Double lng, Double lat) throws IOException {

String url = "/v3/geocode/regeo";

Mapparameters = Maps.newHashMap();

parameters.put("key",mapKey);

parameters.put("location",lng+","+lat);

parameters.put("poitype","");

parameters.put("radius","");

parameters.put("extensions","base");

parameters.put("batch","true");

String resultData = HttpUtil.get(url, parameters, 3000, 3000, "UTF-8");

if (StringUtils.isNotBlank(resultData)) {

JSONObject jsonObject = (JSONObject) JSON.parseObject(resultData.toString()).getJSONArray("regeocodes").get(0);

JSONObject addressComponent = jsonObject.getJSONObject("addressComponent");

return addressComponent.getString("province").replace("省","")+""+addressComponent.getString("city");

}else{

return "";

}

}

3、根据ip地址获取省市区

/**

* 根据ip获取地址

* @param ip

* @return

*/

public static String getAddressByIp(String ip){

log.info("getAddressByIp ip={}",ip);

try {

String url = "/v3/ip";

Mapparameters = Maps.newHashMap();

//ip=114.247.50.2&output=xml&key=

parameters.put("ip",ip);

parameters.put("key",mapKey);

String jsonResult = HttpUtil.get(url, parameters, 3000, 3000, "UTF-8");

if (null!=jsonResult) {

log.info("getAddressByIp result={}",jsonResult);

JSONObject resultObj = JSONObject.parseObject(jsonResult);

String returnStr = resultObj.getString("province")+","+resultObj.getString("city");

if(returnStr.contains("[],[]")){

return "地球村";

}

return returnStr;

}

} catch (Exception e) {

log.error("getAddressByIp error={}",e);

}

return "地球村";

}

4、根据商家关键字、城市名 搜索商家标注信息

/**

* 查找附近的数据

* @param keywords

* @param city

* @param page

* @param pagesize

* @return

*/

public static JSONArray searchMapNearby(String keywords,String city,int page,int pagesize){

log.info("searchMapNearby keywords={}",keywords);

try {

String url = "/v3/place/text";

Mapparameters = Maps.newHashMap();

///v3/place/text?key=您的key&keywords=电影院&types=&city=深圳&children=1&offset=20&page=1&extensions=all

parameters.put("key",mapKey);

parameters.put("keywords",keywords);

parameters.put("types","");

parameters.put("city",city);

parameters.put("children",1);

parameters.put("offset",pagesize);

parameters.put("page",page);

parameters.put("extensions","all");

String jsonResult = HttpUtil.get(url, parameters, 3000, 3000, "UTF-8");

if (StringUtils.isNotBlank(jsonResult)) {

log.info("searchMapNearby result={}",jsonResult);

JSONObject resultJson = JSON.parseObject(jsonResult);

JSONArray pois = resultJson.getJSONArray("pois");

return pois;

}

} catch (Exception e) {

log.error("searchMapNearby error={}",e);

//异常返回空数组

return new JSONArray();

}

return null;

}
