Java调用百度地图api获取经纬度获取地址

您可以使用百度地图提供的Web服务API，通过Java代码调用实现获取经纬度和地址的功能。以下是一些简单的示例代码：

1. 获取经纬度：

import java.net.*;
import java.io.*;

public class GetLocation {
  public static void main(String[] args) throws Exception {
    String address = "北京市海淀区上地十街10号";
    String url = "http://api.map.baidu.com/geocoder/v2/?address=" + 
        URLEncoder.encode(address, "UTF-8") + "&output=json&ak=你的AK";
    URLConnection conn = new URL(url).openConnection();
    BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String line;
    while ((line = br.readLine()) != null) {
      if (line.contains("\"lng\":")) {
        System.out.println("经度：" + line.split(":")[1].split(",")[0]);
      } else if (line.contains("\"lat\":")) {
        System.out.println("纬度：" + line.split(":")[1]);
      }
    }
    br.close();
  }
}

2. 获取地址：

import java.net.*;
import java.io.*;

public class GetAddress {
  public static void main(String[] args) throws Exception {
    String location = "40.056878,116.30815";
    String url = "http://api.map.baidu.com/geocoder/v2/?location=" + 
        location + "&output=json&pois=1&ak=你的AK";
    URLConnection conn = new URL(url).openConnection();
    BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String line;
    while ((line = br.readLine()) != null) {
      if (line.contains("\"formatted_address\":")) {
        System.out.println("地址：" + line.split(":")[1].replace("\"", ""));
      }
    }
    br.close();
  }
}

其中，AK是您申请的百度地图开放平台的密钥。您需要将代码中的“你的AK”替换为您自己的密钥。
