The Struts dispatcher cannot be found在struts2中出现的问题

 

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]
 at org.apache.struts2.views.jsp.TagUtils.getStack(TagUtils.java:60)
 at org.apache.struts2.views.jsp.StrutsBodyTagSupport.getStack(StrutsBodyTagSupport.java:44)
 at org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag(ComponentTagSupport.java:48)

解决办法：
1.引入
<%@ taglib prefix="s"  uri="/struts-tags" %>

2.在web.xml中未将拦截的*.action改成/* 

 

 <filter>
  	<filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>  
  </filter>
  <filter-mapping>
  	<filter-name>struts2</filter-name>
	<url-pattern>/*</url-pattern>
  </filter-mapping>

 

 

一般第二种 情况比较多。是没有改WEB.XML中的拦截

我居然出现了第二种情况，太菜了。
jsp中使用了struts的标签，如果这边只拦截action的话，那就会出现jsp中struts标签无法解析的情况了吧。
