部署環境是tomcat8 + struts2.3 + IDEA2016

這是啟動時的報錯信息

這是Tomcat Localhost Log的報錯信息，我的包都已經正確引入了啊，為什么會ClassNotFoundException呢？

java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

這是Tomcat Catalina Log的報錯信息

15-Oct-2016 11:11:02.908 SEVERE [RMI TCP Connection(2)-127.0.0.1] org.apache.catalina.core.StandardContext.startInternal Context [] startup failed due to previous errors

這是com.zxy.UserAction.java內容

package com.zxy;import com.opensymphony.xwork2.ActionSupport;/*** Created by alps on 10/15/16.*/ public class UserAction extends ActionSupport { public String add() throws Exception { return "add"; }public String update() throws Exception { return "update"; } }

這是struts.xml文件內容

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"><struts> <package name="myPackage" extends="struts-default"> <action name="userAction" class="com.zxy.UserAction"> <result name="add">index.jsp</result> <result name="update">index.jsp</result> </action> </package> </struts>

web.xml內容，IDEA自動幫我新建的，沒有修改過

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"version="3.1"> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>

第一個Struts程序，報錯信息看得不是很懂，希望大神指教！
