java高德地图坐标回显的代码

以下是一个简单的Java高德地图坐标回显的示例代码：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;

public class GaoDeAPI {

    public static void main(String[] args) {
        String url = "https://restapi.amap.com/v3/geocode/regeo?key=您的key&location=116.481488,39.990464&radius=1000&extensions=all&batch=false&roadlevel=0";
        String result = sendGet(url);
        System.out.println(result);
    }

    public static String sendGet(String url) {
        String result = "";
        BufferedReader in = null;
        try {
            URL realUrl = new URL(url);
            URLConnection connection = realUrl.openConnection();
            connection.connect();
            in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            while ((line = in.readLine()) != null) {
                result += line;
            }
        } catch (Exception e) {
            System.out.println("发送GET请求出现异常！" + e);
            e.printStackTrace();
        } finally {
            try {
                if (in != null) {
                    in.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return result;
    }
}

该代码使用Java的URLConnection类与高德地图API进行交互，请求返回的结果为JSON格式的数据。您需要将代码中的“您的key”替换为您自己的高德地图开发者密钥，并将“location”参数的经纬度值替换为您想要查询的地点的经纬度。执行代码后，您将获得包括地址、邮编、城市、经纬度等信息的返回结果。
