Java コードを使用して Baidu Maps 上の場所のあいまい検索を実装するにはどうすればよいですか?

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;

public class BaiduMapSearch {
    public static void main(String[] args) throws IOException {
        // 设置百度地图开放平台的开发者密钥
        String apiKey = "your_api_key";
        // 设置搜索的关键字
        String keyword = "餐馆";

        // 对关键字进行URL编码
        String encodedKeyword = URLEncoder.encode(keyword, "UTF-8");

        // 构造API请求URL
        String url = "http://api.map.baidu.com/place/v2/search?query=" + encodedKeyword + "&region=全国&output=json&ak=" + apiKey;

        // 发起HTTP请求
        HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
        connection.setRequestMethod("GET");
        connection.setConnectTimeout(5000);
        connection.setReadTimeout(5000);
        
        // 获取搜索结果
        BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        String line;
        StringBuilder result = new StringBuilder();
        while ((line = reader.readLine()) != null) {
            result.append(line);
        }

        // 输出搜索结果
        System.out.println(result.toString());

        // 关闭连接和流
        reader.close();
        connection.disconnect();
    }
}
