通过配置不同的后缀,

比如 struts的请求路径你配置 .action  .jsp

servlet的路径可以不配置后缀


<filter>
  <filter-name>struts2</filter-name>  
    <filterclass>
        org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
    </filter-class>
</filter>

 <filter-mapping>
       <filter-name>struts2</filter-name>
       <url-pattern>*.do</url-pattern>
       <url-pattern>*.action</url-pattern>
       <url-pattern>*.jsp</url-pattern>
 </filter-mapping>

<servlet>
   <description></description>

   <display-name>AjaxServerServlet</display-name>

   <servlet-name>AjaxServerServlet</servlet-name>

   <servlet-class>com.test.servlet.AjaxServerServlet</servlet-class>
</servlet>

 <servlet-mapping>
      <servlet-name>AjaxServerServlet</servlet-name>
        
    <url-pattern>/AjaxServerServlet</url-pattern>
 </servlet-mapping>


你可以根据你的需要更改后缀

如果还不行请加servlet配置 <url-pattern>/AjaxServerServlet.htm</url-pattern>
