Question

struts.xml 用include引入多个xml文件时报错

我的struts.xml不在默认的目录下，我放在了sgmtu.edu.cn.config.struts包下，同时我在web.xml 下的配置是这样的：
<filter>
<filter-name>sturts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
<init-param>
<param-name>config</param-name>
<!-- 配置装载struts.xml路径，其中struts.xml放在 sgmtu/edu/cn/config/struts/下-->
<param-value>struts-default.xml,struts-plugin.xml,sgmtu/edu/cn/config/struts/struts.xml</param-value>
</init-param>
</filter>

但是我在struts.xml中用includ引入其它的xml文件如下：
<include file="struts-test.xml" />
struts.xml和struts-test.xml是在同一个目录下，也就是在src下的sgmtu.edu.cn.config.struts包下，但是访问struts-test.xml的say.action时就出错了：
There is no Action mapped for action name say. - [unknown location]

不知道是什么原因，希望有好心人解答
