本文介绍了当使用Struts2标签遇到TheStrutsdispatcher无法找到的问题时的常见原因及解决方案。通常是因为没有正确配置Struts2的过滤器或未引入正确的标签库。文章提供了具体的XML配置示例来帮助解决问题。

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.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/*

Xml代码  

<filter>  

    <filter-name>struts2</filter-name>  

   <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>    

 </filter>

    <filter-name>struts2</filter-name>  

<url-pattern>/*</url-pattern>
