shiro框架的使用

1.配置二级缓存

<ehcache updateCheck="false" name="shiroCache">

    <defaultCache
            maxElementsInMemory="10000"
            eternal="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            overflowToDisk="false"
            diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120"
            />
</ehcache>

2.配置shiro框架

<?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-3.0.xsd"
       default-lazy-init="true">

    <description>Shiro</description>

    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <!-- Single realm app.  If you have multiple realms, use the ‘realms‘ property instead. -->
        <property name="realm" ref="authRealm"/>
        <!-- 二级缓存 -->
        <property name="cacheManager" ref="shiroEhcacheManager"/>
    </bean>

    <!-- 自定义权限认证 -->
    <bean id="authRealm" class="cn.xxxx.jk.shiro.AuthRealm">
		<property name="userService" ref="userService"/>
		<property name="credentialsMatcher" ref="passwordMatcher"/>
	</bean>

	<!-- 自定义加密策略 -->
	<bean id="passwordMatcher" class="cn.xxxx.jk.shiro.CustomCredentialsMatcher"/>

    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
        <property name="securityManager" ref="securityManager"/>
        <property name="loginUrl" value="/index.jsp"></property>
        <!-- 没有权限或者失败后跳转的页面 -->
        <property name="successUrl" value="/home.action"></property>
        <property name="filterChainDefinitions">
            <!-- , roles[admin], perms[document:read]-->
            <value>
				/index.jsp* = anon
				/home* = anon
				/sysadmin/login/login.jsp* = anon
				/sysadmin/login/logout.jsp* = anon
				/login* = anon
				/logout* = anon

				/*.* = authc
				/resource/** = anon
            </value>
        </property>
    </bean>

    <!-- 用户授权/认证信息Cache, 采用EhCache  缓存 -->
    <bean id="shiroEhcacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
        <property name="cacheManagerConfigFile" value="classpath:ehcache-shiro.xml"/>
    </bean>

    <!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->
    <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>

    <!-- 生成代理，通过代理进行控制 -->
    <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
          depends-on="lifecycleBeanPostProcessor">
        <property name="proxyTargetClass" value="true"/>
    </bean>

    <!-- 安全管理器 -->
    <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
        <property name="securityManager" ref="securityManager"/>
    </bean>

</beans>
