  1.   

    楼主 你这是struts的问题还是spring的问题呢？
    C:/tomcat/webapps/Spring_3300_Registration_11你的工程 是只用struts 还是struts+spring呢 
      

  2.   

    为题解决了，原来工程里面缺少struts2-convention-plugin-2.1.8.1.jar包，倒进去后发布。后来又在项目里删除了所有jar包，然后添加了以前用过的一个工程的所有jar包，再发布，我发现tomcat里面有两个struts2-convention-plugin.jar包，但是工程里面只有一个，很诡异后来tomcat中项目删除重新发布，问题解决了。谢谢大家的回答。

    我刚遇到过这个问题,你把包都复制到工程的lib目录下就可以了
