本文是針對web應用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><!-- Make sure any request you want accessible to Shiro is filtered. /* catches all --><!-- requests.  Usually this filter mapping is defined first (before all others) to --><!-- ensure that Shiro works in subsequent filters in the filter chain:             -->  <filter-name>shiroFilter</filter-name>  <url-pattern>/*</url-pattern>  <dispatcher>REQUEST</dispatcher>  <dispatcher>FORWARD</dispatcher>  <dispatcher>INCLUDE</dispatcher>  <dispatcher>ERROR</dispatcher></filter-mapping>

參數TargetFilterLifecycle：缺省值為false，即生命周期由Spring app context管理。設置為true時由servlet container管理。

配置applicationContext.xml：

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">    <property name="securityManager" ref="securityManager"/>                                                                                                                                                    <!-- 配置要跳轉的URL -->    <property name="loginUrl" value="/login.jsp"/>    <property name="successUrl" value="/main.jsp"/>    <property name="unauthorizedUrl" value="/err404.jsp"/>                                                                                                                                                    <!-- 配置過濾策略 切記這是FIRST MATCH WINS -->    <property name="filterChainDefinitions">        <value>            /download/** = user            /images/** = anon            /admin/** = authc, roles[admin]            /docs/** = authc, perms[document:read]            /** = authc            /logout.html = logout        </value>    </property></bean>                                                                                                                                                <bean id="myRealm" class="king.common.security.MyRealm"></bean><bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">    <property name="realm" ref="myRealm" /></bean><bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>

另外，DefaultSecurityManager繼承RealmSecurityManager。因此，當需要多個realm時可以使用"realms"property。ShiroFilterFactoryBean提供了Filters屬性，關于Filters：This property is optional: this {@code FactoryBean} implementation will discover all beans in the web application context that implement the {@link Filter} interface and automatically add them to this filter map under their bean name.

如果需要的話可以配置一下，如：

<property name="filters">    <util:map>        <entry key="myAlias1" value-ref="myFilter1"/>    </util:map></property>

filterChainDefinitions這一property的set方法是這樣定義的：

public void setFilterChainDefinitions(String definitions) {    Ini ini = new Ini();    ini.load(definitions);    //did they explicitly state a 'urls' section?  Not necessary, but just in case:    Ini.Section section = ini.getSection(IniFilterChainResolverFactory.URLS);    if (CollectionUtils.isEmpty(section)) {        //no urls section.  Since this _is_ a urls chain definition property, just assume the        //default section contains only the definitions:        section = ini.getSection(Ini.DEFAULT_SECTION_NAME);    }    setFilterChainDefinitionMap(section);}

于是我們便可以使用filterChainDefinitionMap這一property。我們可以寫一個繼承FactoryBean<Section>的類動態構成一個filterChainDefinitionMap。(Ps:Section是實現Map<String,String>的Ini的靜態內部類。)

另外，如果希望使用注解：

<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>
