Spring Acegi Security实例解析三

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"><display-name>MyAcegiProj</display-name><!--  context-param  --><context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/applicationContext-acegi-security.xml</param-value></context-param><!--acegi 的filter链代理--><filter><filter-name>MyAcegiProjFilterChainProxy</filter-name><filter-class>org.acegisecurity.util.FilterToBeanProxy</filter-class><init-param><param-name>targetClass</param-name><param-value>org.acegisecurity.util.FilterChainProxy</param-value></init-param></filter><filter-mapping><filter-name>MyAcegiProjFilterChainProxy</filter-name><url-pattern>/*</url-pattern></filter-mapping><!--装载应用软件的Spring上下文要由WebapplicationContextUtils.getWebApplicationnContext(servletContext)得到.--><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：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

5、index.jsp页面代码如下：

<%@ page language="java" pageEncoding="UTF-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><html><head>    <META HTTP-EQUIV="Refresh" CONTENT="0;URL=userinfo.jsp"></head><body><p>Loading ...</p></body></html>

6、acegilogin.jsp登陆页面信息如下：

<%@ page language="java" pageEncoding="UTF-8"%><%@ page import="org.acegisecurity.ui.AbstractProcessingFilter" %><%@ page import="org.acegisecurity.ui.webapp.AuthenticationProcessingFilter" %><%@ page import="org.acegisecurity.AuthenticationException" %><html>  <head>    <title>Login Page</title>  </head>  <body>    <h1>Login</h1>    <%    String strError = request.getParameter("login_error");        if (null != strError){      %>      <font color="red">        你的登陆失败,请重试。<BR><BR>         原因: <%= ((AuthenticationException) session.getAttribute(AbstractProcessingFilter.ACEGI_SECURITY_LAST_EXCEPTION_KEY)).getMessage() %>      </font>      <%      }//end if      %>    <form action="j_acegi_security_check" method="POST">      <table>        <tr><td>User:</td><td><input type='text' name='j_username' value='<%= session.getAttribute(AuthenticationProcessingFilter.ACEGI_SECURITY_LAST_USERNAME_KEY) %>'></td></tr>        <tr><td>Password:</td><td><input type='password' name='j_password'></td></tr>        <tr><td><input type="checkbox" name="_acegi_security_remember_me"></td><td>2周内自动登录</td></tr>        <tr><td colspan='2'><input name="submit" type="submit"></td></tr>        <tr><td colspan='2'><input name="reset" type="reset"></td></tr>      </table>    </form>  </body></html>

7、userinfo.jsp用户信息页面代码如下：

<%@ page language="java" pageEncoding="UTF-8"%><%@ page import="org.acegisecurity.context.SecurityContextHolder"%><%@ page import="org.acegisecurity.userdetails.*"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><title>User Info 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"></head><body>当前用户:<%Object obj = SecurityContextHolder.getContext().getAuthentication();if (null != obj){Object userDetail = SecurityContextHolder.getContext().getAuthentication().getPrincipal();String username = "";if (userDetail instanceof UserDetails) {username = ((UserDetails) userDetail).getUsername();} else {username = userDetail.toString();}out.print(username);out.print("<br><a href=\"j_acegi_logout\">注销</a>");}else{out.print("当前没有有效的用户");out.print("<br><a href=\"acegilogin.jsp\">登陆</a>");}%></body></html>

OK，3Q!
