Question

struts2环境配置好之后为什么老报这个错？jar包是从官网上下的，应该不是jar包的问题，难道web.xml配错了？

Dispatcher initialization failed

纠结呀，请大神指点。

Answer 1

FilteDispatcher过时了，用
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter代替。
还有一种可能就是你可能少包，现在的struts2不仅仅是那5个核心包了，还扩展了其他的包，例如Commons-fileupload，Commons-IO包等
应该是这些问题，看提示是少jar包

Answer 2

遇到过同样的问题，struts2 里面很多jar,首先选择需要的那几个核心包,如果是配置SSH,保留那个struts-spring-plugin等等，不要全部导进去。

Answer 3

刷新一下你的工程，用eclipse clean一下你的tomcat让它重新发布。
