        //http://api.map.baidu.com/geocoder/v2/?address="地址"&output=json&ak="你的AK"

            JSONObject obj = JSONObject.parseObject(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");
                location = lng+","+lat;
            } else {
                System.out.println("未找到相匹配的经纬度！");
            }
        } catch (Exception e) {
            System.out.println("未找到相匹配的经纬度，请检查地址！");
        }
        return location;
    }

    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(), "UTF-8"));
            String inputLine = null;
            while ((inputLine = in.readLine()) != null) {
                json.append(inputLine);
            }
            in.close();
        } catch (MalformedURLException e) {
        } catch (IOException e) {
        }
        return json.toString();
    }
    public static void main(String[] args) {
        String location = getLngAndLat("江苏省苏州吴中区晋合广场");
        System.out.println(location);
    }
}

运行main方法结果如下：
