一、搭建Maven项目：

　　所需引用的jar包如下：

　　pom.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    <modelVersion>4.0.0</modelVersion>
    <packaging>war</packaging>

    <name>SpringSecurityLearn</name>
    <groupId>org.yoki.edu</groupId>
    <artifactId>SpringSecurityLearn</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>

            <artifactId>spring-security-web</artifactId>
            <version>3.2.0.RELEASE</version>
        </dependency>
        <dependency>

</project>

二、各个配置文件：

　　web.xml文件的配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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">

    <!--载入Spring配置文件-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext*.xml</param-value>
    </context-param>

    <!--配置SpringSecurity过滤器-->
    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--配置Spring监听器，此处必须配置，否则访问的时候将出现下面的错误!!!-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    
    <!--配置首页-->
    <welcome-file-list>
        <welcome-file>dispatcher.jsp</welcome-file>
    </welcome-file-list>
    
</web-app>

　　Spring监听器，此处必须配置，否则访问的时候将出现下面的错误:

　　applicationContent.xml配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<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"

        http://www.springframework.org/schema/security
        http://www.springframework.org/schema/security/spring-security.xsd">

    <!-- http部分配置如何拦截用户请求。auto-config=‘true‘将自动配置几种常用的权限控制机制，包括form, anonymous, rememberMe -->
    <http auto-config=‘true‘>
        <!-- 设置URL权限 -->
        <!-- Spring Security采用的是一种就近原则，就是说当用户访问的url资源满足多个intercepter-url时，系统将使用第一个符合条件的intercept-url进行权限控制 -->
        <!-- 此处权限的名称必须以ROLE_作为前缀，如果不这样做，在启动Web容器的时候就将报错，错误如下图-->
        <intercept-url pattern="/admin.jsp" access="ROLE_ADMIN"/>
        <intercept-url pattern="/**" access="ROLE_USER"/>
    </http>

    <authentication-manager>
        <authentication-provider>
            <user-service>
                <!-- 创建一个用户，用户名为admin，密码admin，分配ROLE_USER、ROLE_ADMIN两个角色 -->
                <user name="admin" password="admin" authorities="ROLE_USER, ROLE_ADMIN"/>
                <!-- 创建一个用户，用户名为user，密码user，分配ROLE_USER两个角色 -->
                <user name="user" password="user" authorities="ROLE_USER"/>
            </user-service>
        </authentication-provider>
    </authentication-manager>

</beans:beans>

　　权限的名称必须以ROLE_作为前缀，如果不这样做，在启动Web容器的时候就将报错:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.springframework.security.filterChains‘: Cannot resolve reference to bean ‘org.springframework.security.web.DefaultSecurityFilterChain#0‘ while setting bean property ‘sourceList‘ with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.springframework.security.web.DefaultSecurityFilterChain#0‘: Cannot resolve reference to bean ‘org.springframework.security.web.access.intercept.FilterSecurityInterceptor#0‘ while setting constructor argument with key [11]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.springframework.security.web.access.intercept.FilterSecurityInterceptor#0‘: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Unsupported configuration attributes: [AROLE_ADMIN, AROLE_USER]

三、页面的编写：

　　dispatcher.jsp，此页面只起到一个页面跳转的作用。

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h1>Hello this is dispatcher.jsp</h1>
    <div>if you want go to admin.jsp , please click <a href="admin.jsp">here</a> !</div>
    <div>if you want go to index.jsp , please click <a href="index.jsp">here</a> !</div>
</body>
</html>

　　index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h1>Hello this is index.jsp</h1>
</body>
</html>

　　admin.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h1>Hello this is admin.jsp</h1>
</body>
</html>
