请问一下这是什么错误啊？

已经解决好了，是我的jar包没有成功导入，还是要谢谢大家的回答

java.lang.ClassNotFoundException: 这个异常表示未找到相应的类，而接下来它显示的是哪种类找不到，你的异常显示的org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter这个找不到，你看看是不是还有包没导进来。

struts2的jar包的版本是多少？
确认web.xml和struts.xml名称是否配置正确。

[lipan112000]

struts2 web.xml配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>
			org.apache.struts2.dispatcher.FilterDispatcher

	</filter>
	<filter-mapping>
		<filter-name>struts2</filter-name>

	</filter-mapping>


	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

struts.xml 配置：

[

	"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
	"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
        <package name="xxxx" extends="struts-default">
        </package>
</struts>

struts2 jar的版本问题。

[fei381895649fei]

少了,struts2-core-2.1.8.1.jar你加上去..应该没问题的
