shiro配置详解

1、配置web.xml


<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>shiroFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">
	
	<!-- needed for ContextLoaderListener -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>

	<!-- Bootstraps the root web application context before servlet initialization -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<!-- The front controller of this Spring Web application, responsible for handling all application requests -->
	<servlet>
		<servlet-name>spring</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<!-- Map all requests to the DispatcherServlet for handling -->
	<servlet-mapping>
		<servlet-name>spring</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
	<!-- Shiro Filter is defined in the spring application context: -->
	<!-- 
	1. 配置  Shiro 的 shiroFilter.  
	2. DelegatingFilterProxy 实际上是 Filter 的一个代理对象. 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>shiroFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
	
</web-app>

2、配置applicationContext.xml
1）配置securityManager
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="cacheManager" ref="cacheManager"/>
<property name="authenticator" ref="authenticator"></property>

<property name="realms">
<list>
<ref bean="jdbcRealm"/>
<ref bean="secondRealm"/>
</list>
</property>

<property name="rememberMeManager.cookie.maxAge" value="10"></property>
</bean>
3、securityManager依赖cacheManager
需要加入 ehcache 的 jar 包及配置文件ehcache.xml.
<bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManagerConfigFile" value="classpath:ehcache.xml"/>
</bean>
4、配置Realm，直接实现org.apache.shiro.realm.Realm
<bean id="jdbcRealm" class="com.atguigu.shiro.realms.ShiroRealm">
<property name="credentialsMatcher">
<bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
<property name="hashAlgorithmName" value="MD5"></property>
<property name="hashIterations" value="1024"></property>
</bean>
</property>
</bean>
5、配置bean生命周期的处理管理器， LifecycleBeanPostProcessor. 可以自定的来调用配置在 Spring IOC 容器中 shiro bean 的生命周期方法
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>
6、启用 IOC 容器中使用 shiro 的注解. 但必须在配置了 LifecycleBeanPostProcessor 之后才可以使用.
<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>

6.1 id 必须和 web.xml 文件中配置的 DelegatingFilterProxy 的 <filter-name> 一致.
若不一致, 则会抛出: NoSuchBeanDefinitionException. 因为 Shiro 会来 IOC 容器中查找和 <filter-name> 名字对应的 filter bean.

<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="/list.jsp"/>
<property name="unauthorizedUrl" value="/unauthorized.jsp"/>

<property name="filterChainDefinitionMap" ref="filterChainDefinitionMap"></property>

</bean>

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="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.xsd">

    <!--

spring-servlet.xml配置

1、配置代理前后缀

<?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:mvc="http://www.springframework.org/schema/mvc"

	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.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-4.0.xsd">
	
	<context:component-scan base-package="com.atguigu.shiro"></context:component-scan>
	
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
	
	<mvc:annotation-driven></mvc:annotation-driven>

</beans>
