利用 Jsoup 和 多线程下载旺旺英语MP3

import java.io.IOException;import org.jsoup.Jsoup;import org.jsoup.nodes.Document;import org.jsoup.nodes.Element;import org.jsoup.select.Elements;public class Snippet {public static void main(String[] args) throws IOException{String baseUrl = "";Document listDoc = Jsoup.connect("").get();Elements dd = listDoc.select("td.category td.category_main a.list");for(Element element: dd){String mp3PageUrl = baseUrl + element.attr("href");//System.out.println(mp3PageUrl);Document mp3Doc = Jsoup.connect(mp3PageUrl).get();Elements mp3Elements = mp3Doc.select("a.wwmp3");if(null != mp3Elements && mp3Elements.size()>0){String mp3Url = baseUrl + mp3Elements.get(0).attr("href");String fileName = mp3Url.substring(mp3Url.lastIndexOf("/"));//System.out.println(fileName);DownLoad thread = new DownLoad(mp3Url, "F:/wwenglish"+fileName);thread.start();}}}}

import java.io.BufferedOutputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.URL;public class DownLoad extends Thread {public DownLoad(String mp3Url, String filepath) {// Open a URL Streamtry {URL url = new URL(mp3Url);InputStream in = url.openStream();OutputStream out = new BufferedOutputStream(new FileOutputStream(filepath));for (int b; (b = in.read()) != -1;) {out.write(b);}out.close();in.close();} catch (IOException e) {e.printStackTrace();}}}实现了如下链接中所描述的功能, 原文代码不完整. 这里不使用 HttpClient, 单单使用 Jsoup 就达到了目的.

简单 使用 httpclient jsoup 做的 提取 旺旺英语
