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">

	<!--  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

		</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：

            </bean>
        </property>
    </bean>    
</beans>

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 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!
