Shiro权限配置错误There is no filter with name 'anno' to apply to chain

配置shiroFilter时出现如下错误：

十一月 07, 2017 7:29:34 下午 org.apache.catalina.core.StandardContext filterStart
严重: Exception starting filter shiroFilter
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'shiroFilter': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: There is no filter with name 'anno' to apply to chain [/preLogin] in the pool of available Filters.  Ensure a filter with that name/path has first been registered with the addFilter method(s).

shiroFilter配置如下：

    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
      <property name="securityManager" ref="securityManager" />
      <property name="loginUrl" value="/preLogin" />
      <property name="successUrl" value="main/index" />
      <property name="unauthorizedUrl" value="/preLogin" />
      <property name="filterChainDefinitions">
        <value>
          /preLogin                =     anno
          /userregister            =     anno
          /registerpage            =     anno
          /static/**               =     anno
          /**                      =     user
        </value>
      </property>
    </bean>

原因：无访问权限直接访问的配置不是“anno”而是“anon”。将上述配置改为

    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
      <property name="securityManager" ref="securityManager" />
      <property name="loginUrl" value="/preLogin" />
      <property name="successUrl" value="main/index" />
      <property name="unauthorizedUrl" value="/preLogin" />
      <property name="filterChainDefinitions">
        <value>
          /preLogin                =     anon
          /userregister            =     anon
          /registerpage            =     anon
          /static/**               =     anon
          /**                      =     user
        </value>
      </property>
    </bean>

就解决了。
