方式一 通过调用接口（时间高达1s）
package cn.iocoder.yudao.module.supplier.utils;import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;/**** 区域划分代码工具类 只需要传 相应代码值 就会返回 对应区域*/
public class AdministrativeRegionUtil {private static final String BASE_URL = "https://xingzhengquhua.bmcx.com/";public static String getAdministrativeRegionData(String regionCode) {regionCode = padRegionCode(regionCode);String urlString = BASE_URL + regionCode + "__xingzhengquhua/";StringBuilder result = new StringBuilder();try {URL url = new URL(urlString);HttpURLConnection conn = (HttpURLConnection) url.openConnection();conn.setRequestMethod("GET");int responseCode = conn.getResponseCode();if (responseCode == HttpURLConnection.HTTP_OK) { // successBufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));String inputLine;while ((inputLine = in.readLine()) != null) {result.append(inputLine);}in.close();} else {System.out.println("GET request not worked");}} catch (Exception e) {e.printStackTrace();}return result.toString();}public static String padRegionCode(String regionCode) {if (regionCode == null) {throw new IllegalArgumentException("Region code cannot be null");}return String.format("%-12s", regionCode).replace(' ', '0');}public static String parseRegionData(String html) {Document doc = Jsoup.parse(html);Element h3Element = doc.selectFirst("td:contains(行政区划代码) h3");Element spanElement = doc.selectFirst("td:contains(行政区划代码) span");if (h3Element != null && spanElement != null) {String regionName = h3Element.text();String regionCode = spanElement.text();return "RegionName: " + regionName + ", RegionCode: " + regionCode;}return "Data not found";}public static String getAndParseRegionData(String regionCode) {String htmlData = getAdministrativeRegionData(regionCode);return parseRegionData(htmlData);}public static void main(String[] args) {String regionCode = "650000"; // Example region codeString parsedData = getAndParseRegionData(regionCode);System.out.println(parsedData);}
}
运行之后代码
方式二 通过读文件 存入redis缓存中
