因为项目需要给地址栏的重要字段加密。现整理如下：

1、需要用JS给地址栏的字段加密

2、将地址栏的加密字段传给Action进行解密

第一步、在JS方面的加密解密算法：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <base href="<%=basePath%>">        <title>My JSP 'index.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">--><script type="text/javascript" src="js/rollups/aes.js"></script>  <script type="text/javascript" src="js/components/mode-ecb.js"></script><script type="text/javascript">  function Encrypt(word){  var key = CryptoJS.enc.Utf8.parse("abcdefgabcdefg12");   var srcs = CryptoJS.enc.Utf8.parse(word);  var encrypted = CryptoJS.AES.encrypt(srcs, key, {mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});  return encrypted.toString();  }  function Decrypt(word){  var key = CryptoJS.enc.Utf8.parse("abcdefgabcdefg12");   var decrypt = CryptoJS.AES.decrypt(word, key, {mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});  return CryptoJS.enc.Utf8.stringify(decrypt).toString();  }  alert(Encrypt("我爱你"));  alert(Decrypt(Encrypt("我爱你")));  </script>     </head>    <body>    This is my JSP page. <br>  </body></html>

第二步，在Action内的加密，解密算法。

import java.math.BigInteger;import javax.crypto.Cipher;import javax.crypto.KeyGenerator;import javax.crypto.spec.SecretKeySpec;import org.apache.commons.codec.binary.Base64;import sun.misc.BASE64Decoder;/** * 编码工具类 * 实现aes加密、解密 */public class EncryptUtils {/** * 密钥 */private static final String KEY = "abcdefgabcdefg12";/** * 算法 */private static final String ALGORITHMSTR = "AES/ECB/PKCS5Padding";public static void main(String[] args) throws Exception {String content = "我爱你";System.out.println("加密前：" + content);System.out.println("加密密钥和解密密钥：" + KEY);String encrypt = aesEncrypt(content, KEY);System.out.println("加密后：" + encrypt);String decrypt = aesDecrypt(encrypt, KEY);System.out.println("解密后：" + decrypt);}/** * aes解密 * @param encrypt内容 * @return * @throws Exception */public static String aesDecrypt(String encrypt) throws Exception {return aesDecrypt(encrypt, KEY);}/** * aes加密 * @param content * @return * @throws Exception */public static String aesEncrypt(String content) throws Exception {return aesEncrypt(content, KEY);}/** * 将byte[]转为各种进制的字符串 * @param bytes byte[] * @param radix 可以转换进制的范围，从Character.MIN_RADIX到Character.MAX_RADIX，超出范围后变为10进制 * @return 转换后的字符串 */public static String binary(byte[] bytes, int radix){return new BigInteger(1, bytes).toString(radix);// 这里的1代表正数}/** * base 64 encode * @param bytes 待编码的byte[] * @return 编码后的base 64 code */public static String base64Encode(byte[] bytes){return Base64.encodeBase64String(bytes);}/** * base 64 decode * @param base64Code 待解码的base 64 code * @return 解码后的byte[] * @throws Exception */public static byte[] base64Decode(String base64Code) throws Exception{return StringUtils.isEmpty(base64Code) ? null : new BASE64Decoder().decodeBuffer(base64Code);}/** * AES加密 * @param content 待加密的内容 * @param encryptKey 加密密钥 * @return 加密后的byte[] * @throws Exception */public static byte[] aesEncryptToBytes(String content, String encryptKey) throws Exception {        KeyGenerator kgen = KeyGenerator.getInstance("AES");        kgen.init(128);        Cipher cipher = Cipher.getInstance(ALGORITHMSTR);        cipher.init(Cipher.ENCRYPT_MODE, new SecretKeySpec(encryptKey.getBytes(), "AES"));        return cipher.doFinal(content.getBytes("utf-8"));    }/** * AES加密为base 64 code * @param content 待加密的内容 * @param encryptKey 加密密钥 * @return 加密后的base 64 code * @throws Exception */public static String aesEncrypt(String content, String encryptKey) throws Exception {return base64Encode(aesEncryptToBytes(content, encryptKey));}/** * AES解密 * @param encryptBytes 待解密的byte[] * @param decryptKey 解密密钥 * @return 解密后的String * @throws Exception */ public static String aesDecryptByBytes(byte[] encryptBytes, String decryptKey) throws Exception {        KeyGenerator kgen = KeyGenerator.getInstance("AES");        kgen.init(128);        Cipher cipher = Cipher.getInstance(ALGORITHMSTR);        cipher.init(Cipher.DECRYPT_MODE, new SecretKeySpec(decryptKey.getBytes(), "AES"));        byte[] decryptBytes = cipher.doFinal(encryptBytes);        return new String(decryptBytes, "UTF-8");    }/** * 将base 64 code AES解密 * @param encryptStr 待解密的base 64 code * @param decryptKey 解密密钥 * @return 解密后的string * @throws Exception */public static String aesDecrypt(String encryptStr, String decryptKey) throws Exception {return StringUtils.isEmpty(encryptStr) ? null : aesDecryptByBytes(base64Decode(encryptStr), decryptKey);}}

public class StringUtils {public static boolean isEmpty(String encryptStr) {if(encryptStr!=null&&encryptStr.length()>0){//System.out.print(encryptStr);return false;}else{return true;}}}

总结：
1、项目要引用commons-codec-1.10.jar

2、项目的JS端要引用CryptoJS架包

3、请下载
