Shiro 配置过程¶
1. 导入 jar 包¶
- spring mvc 相关
- shiro 相关
2. 配置¶
2.1 web.xml¶
<?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">
<!-- 用于上下文加载器侦听器的配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 初始化监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 这个Spring Web应用程序的前端控制器,负责处理所有申请 -->
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 将所有请求映射到DispatcherServlet以进行处理 -->
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 将所有请求映射到DispatcherServlet以进行处理 -->
<!-- 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>
2.2 applicationContext.xml¶
<?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">
3. 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>
4. 配置 CacheManager¶
4.1 需要加入 ehcache 的 jar 包及配置文件¶
<bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManagerConfigFile" value="classpath:ehcache.xml"/>
</bean>
<bean id="authenticator"
class="org.apache.shiro.authc.pam.ModularRealmAuthenticator">
<property name="authenticationStrategy">
<bean class="org.apache.shiro.authc.pam.AtLeastOneSuccessfulStrategy"></bean>
</property>
</bean>
5. 配置 Realm¶
5.1 直接配置实现了 org.apache.shiro.realm.Realm 接口的 bean¶
<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>
<bean id="secondRealm" class="com.atguigu.shiro.realms.SecondRealm">
<property name="credentialsMatcher">
<bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
<property name="hashAlgorithmName" value="SHA1"></property>
<property name="hashIterations" value="1024"></property>
</bean>
</property>
</bean>
6. 配置 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"/>
<!-- Enable Shiro Annotations for Spring-configured beans. Only run after the lifecycleBeanProcessor has run: -->
7. 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>
8. 配置 ShiroFilter¶
- 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
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
- authc:必须认证(即登录)后才可能访问的页面
- logout:登出
- roles:角色过滤器
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="securityManager" ref="securityManager"/>
<!-- 登陆页面 -->
<property name="loginUrl" value="/login.jsp"/>
<!-- 登陆成功页面 -->
<property name="successUrl" value="/list.jsp"/>
<!-- 无权限页面 -->
<property name="unauthorizedUrl" value="/unauthorized.jsp"/>
<property name="filterChainDefinitionMap" ref="filterChainDefinitionMap"></property>
<property name="filterChainDefinitions">
<value>
/login.jsp = anon
/shiro/login = anon
/shiro/logout = logout
/user.jsp = roles[user]
/admin.jsp = roles[admin]
/** = authc
</value>
</property>
</bean>
9. 配置一个 bean¶
该 bean 实际上是一个 Map,通过实例工厂方法的方式。
<bean id="filterChainDefinitionMap"
factory-bean="filterChainDefinitionMapBuilder" factory-method="buildFilterChainDefinitionMap"></bean>
<bean id="filterChainDefinitionMapBuilder"
class="com.atguigu.shiro.factory.FilterChainDefinitionMapBuilder"></bean>
<bean id="shiroService"
class="com.atguigu.shiro.services.ShiroService"></bean>
</beans>
