Java通过百度地图Api把地址转换为经纬度：
http://api.map.baidu.com/geocoder/v2/?address="地址"&output=json&ak="你的AK"
获取百度AK的方式：
百度地图开发者注册和登入地址：http://lbsyun.baidu.com/apiconsole/key/create

代码如下
package com.example.demo.config.mapUtils;
import com.alibaba.fastjson.JSONObject;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

public static String getLngAndLat(String address) {
String location = "";

//http://api.map.baidu.com/geocoder/v2/?address="地址"&output=json&ak="你的AK"
String url = "http://api.map.baidu.com/geocoder/v2/?address=" + address + "&output=json&ak=你的AK";
try {
String json = loadJSON(url);
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：
