任何帮助都将不胜感激。我不知道Struts2，但。。。 …查看此网站： 对于该版本的struts2，类似乎不在struts2-core.jar中
尝试使用struts2的另一个版本。解决了这个问题。不管出于什么原因，Tomcat只是不喜欢JAR不在webcontent/lib目录中。我把它们放在别处了。然后，当时间限制允许自己回答问题或删除，因为没有人可能回答，因为问题已经解决了。你把它们放在哪里了？！当然是：$jar tf struts2-core-2.3.12.jar | grep struts prepareandexecutefilter>>>org/apache/struts2/dispatcher/ng/filter/struts prepareandexecutefilter.class
