struts2 filter过滤器转换请求地址

先说一下需求，最近项目需要把前台请求的地址进行加密，但是不能影响后台程序流转

这个csdn的代码编辑器真心不好用---------------------------------吐槽一下

url地址加密类：

package test;

import java.security.Key;

import java.security.SecureRandom;

import javax.crypto.Cipher;

import javax.crypto.KeyGenerator;

import sun.misc.BASE64Decoder;

import sun.misc.BASE64Encoder;

public class ThreeDES {

public static String crypt(String content,String password,int i){

try {

KeyGenerator generator = KeyGenerator.getInstance("AES");

generator.init(new SecureRandom(password.getBytes()));

Key key = generator.generateKey();

generator = null;

if(i == 1){

return getEncString(content,key);

}

else if(i == 2){

return getDesString(content,key);

} catch (Exception e) {

return null;

/**

* 加密String明文输入,String密文输出

* 

* @param strMing

* @return

*/

private static String getEncString(String strMing,Key key) {

byte[] byteMi = null;

byte[] byteMing = null;

String strMi = "";

BASE64Encoder base64en = new BASE64Encoder();

byteMing = strMing.getBytes("UTF8");

byteMi = getEncCode(byteMing,key);

strMi = base64en.encode(byteMi);

e.printStackTrace();

} finally {

base64en = null;

byteMing = null;

byteMi = null;

return strMi;

* 解密 以String密文输入,String明文输出

* @param strMi

private static String getDesString(String strMi, Key key) {

BASE64Decoder base64De = new BASE64Decoder();

String strMing = "";

byteMi = base64De.decodeBuffer(strMi);

byteMing = getDesCode(byteMi,key);

strMing = new String(byteMing, "UTF8");

base64De = null;

return strMing;

* 加密以byte[]明文输入,byte[]密文输出

* @param byteS

private static byte[] getEncCode(byte[] byteS,Key key) {

byte[] byteFina = null;

Cipher cipher;

cipher = Cipher.getInstance("AES");

cipher.init(Cipher.ENCRYPT_MODE, key);

byteFina = cipher.doFinal(byteS);

cipher = null;

return byteFina;

* 解密以byte[]密文输入,以byte[]明文输出

* @param byteD

private static byte[] getDesCode(byte[] byteD,Key key) {

cipher.init(Cipher.DECRYPT_MODE, key);

byteFina = cipher.doFinal(byteD);

public static void main(String[] args) {

System.out.println(ThreeDES.crypt("/control/users/index.do", "cccc", 1));

System.out.println(ThreeDES.crypt("ZpbiaZ1Eg1Md/pkr7Tb8XuwvVNrsTletqwfsJmfT92g=", "cccc", 2));

filter类：

package cn.p2p.filter;

import java.io.IOException;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import javax.servlet.http.HttpServletRequest;

public class SetCodeFilter implements Filter {  

public void destroy() {

public void doFilter(ServletRequest request, ServletResponse response,

FilterChain filterChain) throws IOException, ServletException {

HttpServletRequest req = (HttpServletRequest) request;

req.setCharacterEncoding("UTF-8");

//url解密转换操作

System.out.println(req.getRequestURI().substring(1)+"========");

req.getRequestDispatcher(req.getRequestURI().substring(1)).forward(request, response);

// req.getRequestDispatcher("../../yuebao/201402.html").forward(request, response);

// req.getRequestDispatcher(ThreeDES.crypt("ZpbiaZ1Eg1Md/pkr7Tb8XuwvVNrsTletqwfsJmfT92g=", "cccc", 2)).forward(request, response);

filterChain.doFilter(request, response);

public void init(FilterConfig arg0) throws ServletException {

记得如果forward的话struts的filter要加上forward

<!-- 配置struts2 -->
