java获取网页源码

获取网页的源码：

package com.atguigu.crud.controller; import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; import java.io.InputStreamReader; import java.net.MalformedURLException; import java.net.URL; public class ssssss { public static void main(String[] a){ try { URL url=new URL("http://www.baidu.com"); BufferedReader reader=new BufferedReader(new InputStreamReader(url.openStream())); BufferedWriter writer=new BufferedWriter(new FileWriter("index.html")); String line; while((line=reader.readLine())!=null){ System.out.println(line); writer.write(line); writer.newLine(); } reader.close(); writer.close(); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }

 还有一个更简单的： 需要用到 jsoup-1.7.2.jar

String html = Jsoup.connect("你的网址").get().html();
