Shiro与Spring集成

1.新建web工程,加入 Spring 和 Shiro 的 jar 包

2.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <display-name></display-name>    
  <context-param>
     <param-name>contextConfigLocation</param-name>
     <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
 <servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
 </servlet>
 <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>

3. 配置Spring的 applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:p="http://www.springframework.org/schema/p" xmlns:util="http://www.springframework.org/schema/util" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:cache="http://www.springframework.org/schema/cache"
    xsi:schemaLocation="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd  http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.1.xsd

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

    <!--  
    1. 配置 SecurityManager!
    -->     
    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <property name="cacheManager" ref="cacheManager"/>
        <property name="realm" ref="jdbcRealm"/>
    </bean>

    <!--  
    2. 配置 CacheManager. 
    2.1 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>

    <!-- 
        3. 配置 Realm 
        3.1 直接配置实现了 org.apache.shiro.realm.Realm 接口的 bean
    -->     
    <bean id="jdbcRealm" class="com.shiro.realms.ShiroRealm"></bean>
    <!--  
    4. 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: -->
    <!--  
    5. 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. 配置 ShiroFilter. 
    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"/>
        
        <!--  
            配置哪些页面需要受保护. 
            以及访问这些页面需要的权限. 
            1). anon 可以被匿名访问
            2). authc 必须认证(即登录)后才可能访问的页面. 
            3). logout 登出.
            4). roles 角色过滤器
        -->
        <property name="filterChainDefinitions">
            <value>
                /login.jsp = anon
                /shiro/login = anon
                /shiro/logout = logout
                
                /user.jsp = roles[user]
                /admin.jsp = roles[admin]
                
                # everything else requires authentication:
                /** = authc
            </value>
        </property>
    </bean>
    
 </beans>
applicationContext.xml

创建需要的类 实现Realm接口

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.realm.Realm;

public class ShiroRealm implements Realm{

    public AuthenticationInfo getAuthenticationInfo(AuthenticationToken arg0)
            throws AuthenticationException {
        // TODO Auto-generated method stub
        return null;
    }

    public String getName() {
        // TODO Auto-generated method stub
        return null;
    }

    public boolean supports(AuthenticationToken arg0) {
        // TODO Auto-generated method stub
        return false;
    }

}

添加ehcache.xml到classpath

<ehcache>
    <diskStore path="java.io.tmpdir"/>
    <cache name="authorizationCache"
           eternal="false"
           timeToIdleSeconds="3600"

    <defaultCache
        maxElementsInMemory="10000"
        eternal="false"
        timeToIdleSeconds="120"
        timeToLiveSeconds="120"
        overflowToDisk="true"
        />
    <cache name="sampleCache1"
        maxElementsInMemory="10000"

        timeToLiveSeconds="0"
        overflowToDisk="false"
        />  
</ehcache>
ehcache.xml

 

配置sping-servlet (web-inf下)

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

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
