------解决方案--------------------
acitonServlet这个servlet映射的时候出现了错误，

可能是没找到org.apache.struts.action.ActionServlet这个类，比如你没添加struts的jar文件到你项目构建路径（就是WEB-INF/lib目录下）。要么就是你的版本不对，struts2中已经不存在这个类了，你的这个配置是针对struts1的。

另外你的配置还有问题
<servlet>
<servlet-name> acitonServlet </servlet-name>
<servlet-class> org.apache.struts.action.ActionServlet </servlet-class>
</servlet>

改为
<servlet>
<servlet-name> acitonServlet </servlet-name>
<servlet-class> org.apache.struts.action.ActionServlet </servlet-class>
<init-param>
<param-name> config </param-name>
<param-value> /WEB-INF/struts-config.xml </param-value>
</init-param>
<load-on-startup> 2 </load-on-startup>
</servlet>


好好看看struts自带的例子吧
