这是我的applicationContext-shiro.xml里面的shiroFilter

  <!--3. 配置shirofilter --><!-- shiroFilter -->
    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
       <!-- 引入SecurityManager -->    
        <property name="securityManager" ref="securityManager"></property>
    </bean>

这是我的web.xml里面的shiroFilter

    <!-- 加载shiro -->
    <filter>
        <filter-name>shiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>
   
我是因为两个shiroFilter不一样就报了这个错误
