java微信开发---获取微信经纬度/转化（google/百度）经纬度--并且得到地址详情

其实获取微信经纬度，很简单根据我前面的第一篇可以了解到进入要获取微信经纬度的页面时，我们只要先页面授权得到签名就可以了！

这里得到签名的方法网上很多，也可以看我的第一篇文档，直接复制就可以用了！

代码：

这里的是得到微信的信息之后我们进入后台！

代码：

// 得到详情地址@ResponseBody@RequestMapping(value = "/details", method = RequestMethod.POST)public String details(Map<String, Object> model, HttpSession session) {String latitude = request.getParameter("latitude");String longitude = request.getParameter("longitude");System.out.println(latitude);System.out.println(longitude);if (latitude!=null & longitude!=null) {double lat = Double.valueOf(latitude).doubleValue();double lon = Double.valueOf(longitude).doubleValue();// 微信是GPS需要转化地图Gps gps = new Gps(lat, lon);Gps gcj = PositionUtil.gps84_To_Gcj02(gps.getWgLat(), gps.getWgLon());String jsonStr = GetLocationMsg.GetLocationMs(gcj.getWgLat(), gcj.getWgLon());// 因为嵌套太多先解析JSONObject jsonObj = JSONArray.parseObject(jsonStr);JSONArray jsonArray = (JSONArray) jsonObj.get("results");List list = new ArrayList();// 用list保存全部数据for (int i = 0; i < jsonArray.size(); i++) {Userdetails user = (Userdetails) JSONObject.toJavaObject(jsonArray.getJSONObject(i), Userdetails.class);// System.out.println(user.toString());list.add(user.getFormatted_address());}String json = JSON.toJSONString(list); // list转jsonSystem.out.println(json);// 页面上return json;}else {return null;}}

我这里先用google的地图有空再加百度的！其实百度的地图定位不是很好！ getlocationMSG类

package xyz.ibenben.parttime.common.util;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 java.util.ArrayList;import java.util.List;import com.alibaba.fastjson.JSONArray;import com.alibaba.fastjson.JSONObject;/** * google地图得地址详情 * @author admin * */public class GetLocationMsg {public final static void main(String[] args) { /*//String jsonStr = GetLocationMs(22.329157, 114.203258);JSONObject jsonObj = JSONArray.parseObject(jsonStr);JSONArray jsonArray = (JSONArray) jsonObj.get("results");System.out.println(jsonArray);List list = new ArrayList();// 用list保存全部数据for (int i = 0; i < jsonArray.size(); i++) {Userdetails user = (Userdetails) JSONObject.toJavaObject(jsonArray.getJSONObject(i), Userdetails.class);// System.out.println(user.toString());list.add(user.getFormatted_address());}System.out.println(list);*/}public static String GetLocationMs(double d, double f) {String message = "";String url = String.format("http://ditu.google.cn/maps/api/geocode/json?latlng=%s,%s&language=CN",d, f);URL myURL = null;URLConnection httpsConn = null;try {myURL = new URL(url);} catch (MalformedURLException e) {e.printStackTrace();}try {httpsConn = (URLConnection) myURL.openConnection();if (httpsConn != null) {InputStreamReader insr = new InputStreamReader(httpsConn.getInputStream(), "UTF-8");BufferedReader br = new BufferedReader(insr);String data = null;while ((data = br.readLine()) != null) {message = message + data;}insr.close();}} catch (IOException e) {e.printStackTrace();}return message;}}

这个是解析的类

/** * json 类 * @author Administrator * */public class Userdetails {private String place_id;private String formatted_address;private String long_name;private String short_name;private String types;private String geometry;@Overridepublic String toString() {return "User{" + "formatted_address='" + formatted_address + '\'' + "" + ",geometry='" + geometry + '\''+ ",types='" + types + '\'' + '}';}public String getLong_name() {return long_name;}public void setLong_name(String long_name) {this.long_name = long_name;}public String getFormatted_address() {return formatted_address;}public void setFormatted_address(String formatted_address) {this.formatted_address = formatted_address;}public String getShort_name() {return short_name;}public void setShort_name(String short_name) {this.short_name = short_name;}public String getPlace_id() {return place_id;}public void setPlace_id(String place_id) {this.place_id = place_id;}public String getTypes() {return types;}public void setTypes(String types) {this.types = types;}public String getGeometry() {return geometry;}public void setGeometry(String geometry) {this.geometry = geometry;}}

经纬度类

/*** 经纬度类* * @author Administrator**/public class Gps {private double wgLat;private double wgLon;public Gps(double wgLat, double wgLon) {setWgLat(wgLat);setWgLon(wgLon);}public double getWgLat() {return wgLat;}public void setWgLat(double wgLat) {this.wgLat = wgLat;}public double getWgLon() {return wgLon;}public void setWgLon(double wgLon) {this.wgLon = wgLon;}@Overridepublic String toString() {return wgLat + "," + wgLon;}}

到这一步我们就看也在页面得到用户的地址信息了
