根据url抓取jsp内容

根据一个jsp地址，抓取jsp里的内容

代码：

 1 package com.base.util;
 2 
 3 import java.io.BufferedReader;
 4 import java.io.IOException;
 5 import java.io.InputStreamReader;
 6 import java.net.HttpURLConnection;
 7 import java.net.MalformedURLException;
 8 import java.net.URL;
 9 
10 public class FunctionUtil {
11 
12     public static String getHtml(String urlString) {
13         try {
14             StringBuffer html = new StringBuffer();
15             URL url = new URL(urlString);
16             HttpURLConnection conn = (HttpURLConnection) url.openConnection();
17             conn.setDoOutput(true);
18             InputStreamReader isr=new InputStreamReader(conn.getInputStream(),"utf-8");
19             BufferedReader br =new BufferedReader(isr);
20             String temp;
21             while ((temp = br.readLine()) != null) {
22             html.append(temp).append("\n");
23         }
24             br.close();
25             isr.close();
26             return html.toString();
27         } catch (Exception e) {
28             e.printStackTrace();
29             return null;
30         }
31 }
32 }

使用：

 1 getHtml(rootpath+"/page/xzsp/sp_webService.jsp")
