出现上面的问题，是我在修改springMVC整体的URL后缀（原来是MVC）为html的时候出现，我忘记修改shiroFilter的入口mapping的配置为.html造成的错误。

<!-- Shiro Security filter -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>*.mvc</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>

?

应该修改为：

<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>*.html</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
