示例代码:

PrintWriter outprint = response.getWriter();

//String lat = "39.983424"; // 纬度
//String lng = "116.322987";  // 经度
String lng = request.getParameter("jingdu");
String lat = request.getParameter("weidu");
//outprint.print(lng + ";" + lat);

try {

    URL url = new URL("http://api.map.baidu.com/geocoder/v2/?ak=wPPxsfCtNFm4PqEV68jbDdjP7U4twstj&callback=renderReverse&location=" + lat + "," + lng + "&output=json&pois=1");
    HttpURLConnection ucon = (HttpURLConnection) url.openConnection();
    ucon.connect();

    InputStream in = ucon.getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(in, "UTF-8"));
    String str = reader.readLine();
    //outprint.print(str);

    str = str.substring(str.indexOf("(") + 1, str.length() - 1);
    //outprint.print(str);

    JSONObject jsonObject = new JSONObject(str);
    String address = "";
    address = jsonObject.getJSONObject("result").getString("formatted_address");

    outprint.print(address);
    outprint.close();
    outprint = null;

} catch(Exception e) {
    e.printStackTrace();
}
