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>
