<beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd"> <!-- 配置保护资源 --> <!-- 自动配置过滤器链 --> <http auto-config="true">

Spring Security的作用：
1.在访问一个安全资源之前提示用户登录
2.经过检查安全（密码），对用户进行身份验证
3.检查经过身份验证的用户是否具有访问某个安全资源的特权
4.将成功进行身份验证和授权的用户重定向到锁清秋的安全资源
5.对不具备访问安全资源特权的用户显示Access Denid页面
6.在服务器上记录成功进行身份验证的用户，并在用户的的客户机上设置安全cookie。使用该cookie执行下一次身份验证，而无需要求用户登录。
<!-- 配置保护资源 -->
<!-- 自动配置过滤器链 -->
<http auto-config="true">
<!-- access设置角色 角色和用户是多对多的关系-->
<intercept-url pattern="/index.jsp" access="ROLE_user,ROLE_admin"/>
</http>
<!--配置用户 ，可以放在配置文件中或者数据库中 -->
<authentication-manager>
<authentication-provider>
<user-service>
<user name="tom" authorities="ROLE_user,ROLE_tom" password="tom"/>
<user name="mike" authorities="ROLE_manager" password="mike"/>
</user-service>
</authentication-provider>
</authentication-manager>
配置好之后访问站点：
用户tom是可以访问被保护的资源index.jsp的，但是Mike没有授权，即使登录用户名和密码正确依然会显示access denied。
修改applicationContext-security.xml文件，更改默认的保护登录页面：
<!-- 配置保护资源 -->
<!-- 自动配置过滤器链 -->
<http auto-config="true">
<!-- 修改保护登录页面为login.jsp 同时设置验证失败后的页面也是login.jsp 验证成功的页面为sec.jsp -->
<form-login login-page="/login.jsp" authentication-failure-url="/login.jsp" default-target-url="/sec.jsp" />
<!-- access设置角色 角色和用户是多对多的关系-->
<intercept-url pattern="/index.jsp" access="ROLE_user,ROLE_admin"/>
</http>
