Java通过百度地图API获取地址经纬度
import java.util.HashMap; import java.util.Map; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.MalformedURLException; import java.net.URL; import java.net.URLConnection; import net.sf.json.JSONObject; public class LngAndLatUtil { public static Map<String,Double> getLngAndLat(String address){ Map<String,Double> map=new HashMap<String, Double>(); String url = "http://api.map.baidu.com/geocoder/v2/?address="+address+"&output=json&ak=你自己的ak值"; String json = loadJSON(url); JSONObject obj = JSONObject.fromObject(json); if(obj.get("status").toString().equals("0")){ double lng=obj.getJSONObject("result").getJSONObject("location").getDouble("lng"); double lat=obj.getJSONObject("result").getJSONObject("location").getDouble("lat"); map.put("lng", lng); map.put("lat", lat); //System.out.println("经度:"+lng+"---纬度:"+lat); }else{ //System.out.println("未找到相匹配的经纬度!"); } return map; } public static String loadJSON (String url) { StringBuilder json = new StringBuilder(); try { URL oracle = new URL(url); URLConnection yc = oracle.openConnection(); BufferedReader in = new BufferedReader(new InputStreamReader( yc.getInputStream())); String inputLine = null; while ( (inputLine = in.readLine()) != null) { json.append(inputLine); } in.close(); } catch (MalformedURLException e) { } catch (IOException e) { } return json.toString(); } } 把代码中的ak值(红色字部分)更改为你自己的ak值,在百度地图API中注册一下就有。 调用方式: Map<String,Double> map=LngAndLatUtil.getLngAndLat("上海市黄浦区六合路"); System.out.println("经度:"+map.get("lng")+"---纬度:"+map.get("lat"));优质内容筛选与推荐>>
