CryptoJS v3.1.2下载地址： https://code.google.com/p/crypto-js/downloads/list 或 http://www.oschina.net/p/crypto-js/

1、项目结构

2、项目需要导入的jar包

本项目后台用的是struts2，所以需要导入struts2的jar包。把下面的包导入到项目的WebRoot/WEB-INF/lib目录下

3、项目需要导入的js文件

下载CryptoJS v3.1.2后，解压，解压后的文件夹的根目录下有两个目录，其中core-min.js 在components目录下，md5.js在rollups目录下。找到这两个js文件，然后在项目的WebRoot根目录下新建js文件夹，把这两个js文件放在WebRoot/js目录下

4、各个文件的源码

(1) 在src根目录下新建包com.md5.action ，在该包下建立EncryptAction.java

EncryptAction.java

package com.md5.action;

import com.opensymphony.xwork2.ActionContext;

public class EncryptAction {
	private String userName;
	private String password;
	
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	
	public String  encryptByMd5() {
		ActionContext context = ActionContext.getContext();
		context.put("userName", this.userName);
		context.put("password", this.password);
		return "success";
	}
	
}

(2) 在src根目录下新建xml文件struts.xml

struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
	 <!-- 配置 Struts 2 应用中的常量 --> 
	 <constant name="struts.i18n.encoding" value="UTF-8"/> 
	 
	 <package name="md5" extends="struts-default">
	 	<action name="md5Action" class="com.md5.action.EncryptAction" method="encryptByMd5">
			<result name="success">/success.jsp</result>
	 	</action>
	</package>
</struts>

(3) 修改web.xml文件

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

  <!-- 设置struts 2过滤器 -->
  <filter>
      <filter-name>struts 2</filter-name>
      <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
      <filter-name>struts 2</filter-name>
      <url-pattern>/*</url-pattern>
  </filter-mapping>
  
  
  <!-- 设置欢迎页面 -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
  <!-- session超时定义,单位为分钟 -->
  <session-config>
	<session-timeout>30</session-timeout>
  </session-config>
  
</web-app>

(4) 在WebRoot根目录下建立分别index.jsp 、md5Demo.jsp、success.jsp

index.jsp

<%@ 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>首页</title>
  </head>
  <body>
    <a href="md5Demo.jsp">去测试md5实例</a>
  </body>
</html>

md5Demo.jsp

<%@ 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>md5加密实例</title>
	<script type="text/javascript" src="js/core-min.js"></script>
	<script type="text/javascript" src="js/md5.js"></script>
	<script  type="text/javascript">
	    //md5加密函数
	    function EncryptByMd5(){
	        //获取表单中的密码文本框的值
	    	var password = document.getElementById("password").value;
	    	//用CryptoJS库的md5加密算法给密码加密
	    	var passwordMd5 = CryptoJS.MD5(password);
	    	//把加密后的密码值重新赋值给表单中的密码
	    	document.getElementById("password").value = passwordMd5;
	    }
	</script>
  </head>
  <body>
  <form action="md5Action" method="post"> 
  	用户名：<input type="text" name="userName" id="userName" /><br />
  	密  码：<input type="password" name="password" id="password" /><br />
  	<input type="submit" value="提交" onclick="EncryptByMd5()" /><br />
  </form>
  </body>
</html>

success.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%
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>成功跳转</title>
  </head>
  <body>
  	用户名：<s:property value="#request.userName" /><br />
  	密  码：<s:property value="#request.password" /><br />
  </body>
</html>

完成以上所有的步骤后，把项目发布到服务器，用浏览器访问md5Demo.jsp ，输入用户名、密码后，提交，你会看到密码加密后的数据

提交前（密码输入的是：123456789）
