根据地址反编译成经纬度

公司有需求将地址反编译成经纬度，前端同学做了一份，后来觉得其实后台做也可以，就在网上搜罗了一番，修改后的基础代码如下。目的是为了自己记录和大家分享。

public class AddressTool {
public static String getLocationByAddress(String address){
InputStream in =null;
InputStreamReader isr = null;
BufferedReader bufr = null;
    try {
    address= URLEncoder.encode(address, "utf-8");
    String u="http://restapi.amap.com/v3/geocode/geo?address="+address+"&output=JSON&key=9a491a13997579f985c98165bb68d127&s=rsv3";
    URL url = new URL(u);
    in = url.openStream();
    isr = new InputStreamReader(in);
    bufr = new BufferedReader(isr);
    String json;
    if((json=bufr.readLine())!= null){
        //转换json
        Map<String,Object> information= JSON.parseObject(json, Map.class);
        List geocodesList = (List)information.get("geocodes");
        Map<String,Object> map = (Map)geocodesList.get(0);
        String location = String.valueOf(map.get("location"));
        return location;
    }
    } catch (Exception e) {
    e.printStackTrace();
    }finally {
        try {
            if (bufr != null) {
                bufr.close();
            }
            if (isr != null) {
                isr.close();
            }
            if (in != null) {
                in.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return null;
}

public static void main(String[] args){
    String str = "浙江省杭州市西湖区";
    System.out.print(getLocationByAddress(str));
}

}
