关于strtus2过滤器问题

问题：请求 *.action文件，都报http 404错误，为什么呢？
（1）web.xml的过滤器配置（部分），前面是spring security3 过滤器，后边是struts2的过滤器
<!-- SpringSecurity过滤器。 -->

<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>/*</url-pattern>
</filter-mapping>

<!-- <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> -->
<!-- <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> -->
<!-- Struts2拦截器。 -->

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
<init-param>
<param-name>actionPackages</param-name>
<param-value>com.jeaw</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
(2) 这是springSecurity配置applicationContext-security.xml（部分）
<!-- ======================springSecurity过虑链配置开始===================== -->
