1、新建一个Web工程，将以下Jar包导进工程：acegi-security-1.0.3.jar、commons-codec-1.3.jar、commons-logging-1.0.4.jar、mysql-connector-java-5.0.3-bin.jar和spring.jar。

2、在MySql中执行以下SQL语句：

Drop TABLE IF EXISTS `test`.`student`;
    Create TABLE `test`.`student` (
    `name` varchar(40) NOT NULL,
    `psw` varchar(10) NOT NULL,
    `enabled` boolean
    );
    insert into student values("lanp","lanpiao",true);
    insert into student values("ph","ph",true);
    insert into student values("wxh","wxh",true);
    
    Drop TABLE IF EXISTS `test`.`user_privileges`;
    Create TABLE `test`.`user_privileges` (
    `name` varchar(40) NOT NULL,
    `privilege` varchar(40) NOT NULL
    );
    insert into user_privileges values("lanp","ROLE_PRESIDENT");
    insert into user_privileges values("ph","ROLE_SUPERVISOR");
    insert into user_privileges values("wxh","ROLE_USER");

3、web.xml配置信息如下：

<?xml version="1.0" encoding="UTF-8"?>
    <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    	<context-param>
    		<param-name>contextConfigLocation</param-name>
    		<param-value>
    			/WEB-INF/applicationContext-acegi-security.xml
    		</param-value>
    	</context-param>
    	
    	
    	<filter>
    		<filter-name>MyAcegiProjFilterChainProxy</filter-name>
    		<filter-class>
    			org.acegisecurity.util.FilterToBeanProxy
    		</filter-class>
    		<init-param>
    			<param-name>targetClass</param-name>
    			<param-value>

    		</init-param>
    	</filter>
    	<filter-mapping>
    		<filter-name>MyAcegiProjFilterChainProxy</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>
    	
    	
    	<listener>
    		<listener-class>
    			org.springframework.web.context.ContextLoaderListener
    		</listener-class>
    	</listener>
    	
    	<welcome-file-list>
    		<welcome-file>index.jsp</welcome-file>
    	</welcome-file-list>
    	
    </web-app>

4、applicationContext-acegi-security.xml配置文件的信息如下：
