您好！关于高德地图的数据爬取，一般需要使用爬虫技术。以下是一个简单的Java爬虫示例，可以爬取高德地图上的POI（兴趣点）数据：

``` import java.io.*; import java.net.*; import java.util.*; public class AmapSpider { private static final String KEYWORDS = "餐厅"; // 搜索关键词 private static final String CITY = "北京市"; // 搜索城市 private static final int PAGE_SIZE = 20; // 每页记录数 private static final int MAX_PAGES = 100; // 最大页数 public static void main(String[] args) throws Exception { String url = "https://restapi.amap.com/v3/place/text"; String params = "keywords=" + URLEncoder.encode(KEYWORDS, "UTF-8") + "&city=" + URLEncoder.encode(CITY, "UTF-8") + "&offset=" + PAGE_SIZE; for (int i = 1; i <= MAX_PAGES; i++) { String pageParams = params + "&page=" + i; URL requestUrl = new URL(url + "?" + pageParams + "&key=YOUR_AMAP_API_KEY"); HttpURLConnection connection = (HttpURLConnection) requestUrl.openConnection(); connection.setRequestMethod("GET"); int responseCode = connection.getResponseCode(); if (responseCode != 200) { System.err.println("Error: " + responseCode); break; } String response = readResponse(connection); System.out.println(response); } } private static String readResponse(HttpURLConnection connection) throws Exception { try (BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()))) { StringBuilder sb = new StringBuilder(); String line; while ((line = reader.readLine()) != null) { sb.append(line); } return sb.toString(); } } } ```
