Question

我的web.xml：

<filter>
   <filter-name>springSecurityFilterChain</filter-name>
   <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
   <filter-name>springSecurityFilterChain</filter-name>
   <url-pattern>*.xhtml</url-pattern>
</filter-mapping>

<!--Listeners-->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

<!--Params-->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:*-applicationContext.xml</param-value>
</context-param>

我的applicationContext.xml：

<bean id="studentModel" class="ru.spb.herzen.jviewer.model.StudentModel" scope="session">
   <aop:scoped-proxy/>
</bean>
<bean id="sessionFilter" class="ru.spb.herzen.jviewer.filter.SessionFilter" init-method="init">
   <property name="userModel" ref="studentModel"/>
</bean>

<bean id="roleFilter" class="ru.spb.herzen.jviewer.filter.RoleFilter">
   <property name="userModel" ref="studentModel"/>
</bean>

<bean id="springSecurityFilterChain" class="org.springframework.security.web.FilterChainProxy">
   <sec:filter-chain-map path-type="ant">
        <sec:filter-chain pattern="/**" filters="
            sessionFilter,
            roleFilter"/>
   </sec:filter-chain-map>
</bean>

当我尝试登录时，过滤器失败。在debug中，我看到userModel的值为null。我也尝试单独添加过滤器，但结果是一样的。我的错误在哪里？

当我尝试通过spring将bean注入servlet过滤器时的空值
