下面以爬取360浏览器网页为例，代码具有通用性，改变网页路径即可
代码如下
package 爬取网页;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileOutputStream;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.MalformedURLException;
import java.net.URL;
public class Main {
public static void main(String[] args) throws Exception {
URL url=new URL("https://hao.360.cn/?h_lnk");//获取网址
BufferedReader bufferedReader=new BufferedReader(new InputStreamReader(url.openStream(),"utf-8"));//根据网页编码方式
String msg=null;
BufferedWriter bufferedWriter=new BufferedWriter(new OutputStreamWriter(new FileOutputStream("C:/a/360.html"),"utf-8"));
while((msg=bufferedReader.readLine())!=null) {
//System.out.println(msg);
bufferedWriter.append(msg);
bufferedWriter.newLine();
}
bufferedWriter.flush();
bufferedReader.close();
bufferedWriter.close();
}
}
运行代码后在C盘的a文件夹里面会有360.html文件，点击进入360网页
改变文件格式为txt可以查看网页源代码
