1、加入shiro相关依赖的jar包
pom.xml部分内容如下：
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.3.2</version>
</dependency>
2、配置web.xml文件
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app>
<display-name>spring.shiro</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 防止中文乱码过滤器配置 -->
<filter>
<filter-name>springFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
<!-- 配置shiro filter过滤器，被定义在classpath:applicationContext.xml文件里
DelegatingFilterProxy实际上是Filter的代理对象，默认情况下，spring会到IOC容器中查找和<filter-name>对应的filter bean，
也可以通过targetBeanName的初始化参数来配置filter bean的id。
-->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter> <filter-mapping>
<filter-name>springFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping> <filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置自动加载 classpath:applicationContext.xml-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>springShiro</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 配置springmvc -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springShiro</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping> <welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
</web-app>
3、配置applicationContext.xml
1)、配置securityManager，也就是shiro的核心。
2)、配置cacheManager(缓存管理)
3)、配置Realm，自己定义的shiroRealm，必须实现org.apache.shiro.realm.Realm这个接口
4)、配置lifecycleBeanPostProcessor，可以自动的来调用配置在spring IOC 容器中shiro bean的生命周期方法
5)、配置可以使用shiro注解，但必须在配置 lifecycleBeanPostProcessor才可以使用
6)、配置shiroFilter
整个配置文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="

http://www.springframework.org/schema/p/spring-p.xsd
">
<!--
1. 配置securityManager，也就是shiro的核心。
-->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="myRealm" />
<!-- 缓存管理器 -->
<property name="cacheManager" ref="cacheManager" />
</bean>
<!--
2. 配置cacheManager(缓存管理)
-->
<bean id="cacheManager" class="org.apache.shiro.cache.MemoryConstrainedCacheManager">
</bean>
<!--
3. 配置Realm，自己定义的shiroRealm，必须实现org.apache.shiro.realm.Realm这个接口
-->
<bean id="myRealm" class="maven.spring.shiro.realms.ShiroRealm"></bean>
<!--
4.配置lifecycleBeanPostProcessor， 可以自动的来调用配置在spring IOC 容器中shiro bean的生命周期方法 -->
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />
<!--
5.启用IOC容器中使用shiro的注解，但必须在配置 lifecycleBeanPostProcessor才可以使用-->
<bean
class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
depends-on="lifecycleBeanPostProcessor" />
<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager"/>
</bean>
<!--
6. 配置shiroFilter
6.1 id必须和web.xml 文件中配置的DelegatingFilterProxy的filter-name一致
-->
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="securityManager" ref="securityManager" />
<property name="loginUrl" value="/login.jsp" />
<property name="successUrl" value="/user/list.do" />
<property name="unauthorizedUrl" value="/login.jsp" />
<!-- 配置哪些页面需要受保护
以及访问这些页面需要的权限
anon可以被匿名访问，或者说游客可以访问
authc 必须认证之后才能访问，即登录后才能访问的页面
-->
<property name="filterChainDefinitions">
<value>
/login = anon
/index = anon
/** = authc
</value>
</property> </bean> <context:component-scan base-package="maven.spring.shiro">
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>
</beans>
3、配置springmvc文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/beans/spring-mvc.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 配置渲染器 --> <bean id="jspViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<mvc:default-servlet-handler />
<mvc:annotation-driven />
<context:component-scan
base-package="maven.spring.shiro.web.controller"></context:component-scan>
</beans>
这样，整个配置文件就配置完成了。
