java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
你的stuts2的jar包版本不對(duì)。要么是2.1之前的要么就是2.5的。struts2 2.5版本已經(jīng)沒(méi)有這個(gè)
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter了。換回struts2 2.2的版本吧，最新的2.5版本的配置我找不到相應(yīng)的配置教程

不知道

<filter-name>struts-prepare</filter-name>
? ? ? ? <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareFilter</filter-class>
<filter-name>struts-execute</filter-name>
? ? ? ? <filter-class>org.apache.struts2.dispatcher.filter.StrutsExecuteFilter</filter-class>
最新的2.5.2版本要把prepare和execute分開(kāi)配置，可以在struts-2.5.2\src\apps\showcase\src\main\webapp\WEB-INF找個(gè)web.xml參考，進(jìn)行配置就行了

樓上正解，我昨天也出現(xiàn)這種情況，換回老師同款struts2就正常了
