java 根据经纬度获取地址实现代码

public class GetLocation {   public static void main(String[] args) {     // lat 39.97646        //log 116.3039      String add = getAdd("116.3039", "39.97646");     JSONObject jsonObject = JSONObject.fromObject(add);     JSONArray jsonArray = JSONArray.fromObject(jsonObject.getString("addrList"));     JSONObject j_2 = JSONObject.fromObject(jsonArray.get(0));     String allAdd = j_2.getString("admName");     String arr[] = allAdd.split(",");     System.out.println("省："+arr[0]+"/n市："+arr[1]+"/n区："+arr[2]);   }      public static String getAdd(String log, String lat ){     //lat 小 log 大     //参数解释: 纬度,经度 type 001 (100代表道路，010代表POI，001代表门址，111可以同时显示前三项)     String urlString = "http://gc.ditu.aliyun.com/regeocoding?l="+lat+","+log+"&type=010";     String res = "";       try {         URL url = new URL(urlString);        java.net.HttpURLConnection conn = (java.net.HttpURLConnection)url.openConnection();        conn.setDoOutput(true);        conn.setRequestMethod("POST");        java.io.BufferedReader in = new java.io.BufferedReader(new java.io.InputStreamReader(conn.getInputStream(),"UTF-8"));        String line;        while ((line = in.readLine()) != null) {          res += line+"/n";       }        in.close();      } catch (Exception e) {        System.out.println("error in wapaction,and e is " + e.getMessage());      }      System.out.println(res);     return res;    }    }
