import java.net.URL;import net.sf.json.JSONArray;import net.sf.json.JSONObject;public class GetLocation {      public static void main(String[] args) {          // lat 31.2990170   纬度            //log 121.3466440    经度        String add = getAdd("121.3466440", "31.2990170");          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;        }        }

运行结果如下图：

需要注意的是JSONObject和JSONArray的引用是下面两个，否则会报方法JSONObject.fromObject()的错误

import net.sf.json.JSONArray;import net.sf.json.JSONObject;
