JSP 不能用 不支持 STRUTS标签 报错 The Struts dispatcher cannot be found.

Servlet.service() for servlet jsp threw exception

The Struts dispatcher cannot be found.  This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location]

其实 好办，只要在WEB.XML中加入一个过滤器就行了：

 

[html]  

<span style="font-size:18px;"><filter-mapping>   

<filter-name>struts2</filter-name>   

<url-pattern>*.jsp</url-pattern>   

</filter-mapping> </span>
