Answer 1

刚一刷新发现你说没用你把commons-lang包打开看能不能找到java.lang.NoClassDefFoundError: org/apache/commons/lang3/StringUtils这个类

Answer 2

报的错找不到类org/apache/commons/lang3/StringUtils，这个类就是commons-lang这个包里的。
你说你试过没用，可能是你还少其他的包，将这个包导入后，你肯定不是报现在贴出来的这个错。

Answer 3

struts自带StringUtils 是不是没有导入啊。也就是说struts的包导入不全。

Answer 4

导入你说的包后我贴出来的错误如下：

Answer 5

下面是我的实现步骤：实现：
   第一步：创建一个Web工程
   在MyEclipse，通过菜单File->New->Web Project，在Project Name输入工程名称Strut2Travel，点解确定完成创建一个工程。
   简注：MyEclipse属于一个IDE继承开发环境，可以快速的创建Web项目。读者可以手工创建，只需满足项目的文件结构即可。其中WEB-INF文件夹必不可少。   第二步：导入Struts2的核心支持包
   commons-fileupload-1.2.1.jar   commons-io-1.3.2.jar   commons-logging-1.0.4.jar   freeer-2.3.15.jar   ognl-2.7.3.jar   struts2-core-2.1.8.1.jar   xwork-core-2.1.6.jar   javassist-3.11.0.GA.jar
   简注：Struts2有大量的jar包，支持大量的功能，不同类型的应用可能需要不同的包支持。以上的5个包为Struts2的核心包，使用Struts2必须使用。   第三步：配置struts2转发过滤器
   编辑web.xml文件，添加以下内容
 <filter>
  <filter-name>struts2</filter-name>
  <filter-class>
   org.apache.struts2.dispatcher.FilterDispatcher
  </filter-class>
 </filter>
 <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>
   简注：“/*”表示涉及本工程的所有浏览器端的请求都经过struts2过滤器处理。    第四步：创建输入页面login.jsp、结果页面welcome.jsp和error.jsp
login.jsp
<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head><title>登录界面</title></head>
  <body>
    <form action="LoginAction.action">
       用户名：<input name="username"><br>
       密 码：<input type="password" name="userpass"><br>
      <input type="submit" value="提 交">
      <input type="reset"  value="取 消">
    </form>
  </body>
</html>
welcome.jsp
<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>欢迎</title>
  </head>
  <body>
    <font color="red" size="10">登录成功！</font>
  </body>
</html>
error.jsp
<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title></title>
  </head>
  <body>
    <font color="red" size="10">用户或密码错误！</font>
  </body>
</html>
    简注：本实例是最简单的应用，以上为纯JSP文件，Struts2提供大量使用的标签，本书后面的实例会使用到。    第五步：创建Action文件LoginAction和struts2.xml文件
LoginAction.java
package com;import com.opensymphony.xwork2.ActionSupport; public class LoginAction extends ActionSupport{
 private String username;
 private String userpass;
 
 public String execute(){
  if("daniel".equals(username)&&"abcde".equals(userpass))
   return SUCCESS;
  else
   return ERROR;
 }
 
 public String getUsername() {
  return username;
 }
 public void setUsername(String username) {
  this.username = username;
 }
 public String getUserpass() {
  return userpass;
 }
 public void setUserpass(String userpass) {
  this.userpass = userpass;
 }
}
    简注：默认配置情况下执行execute()方法，实际应用中经常更改配置。本书后面将深入讲解。注意本类中的username和userpass必须和网页文件的name属性名一致。
struts.xml
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
 <package name="struts2demo" extends="struts-default">
   <action name="loginAction" class="com.LoginAction">
     <result name="success">/welcome.jsp</result>
     <result name="error">/error.jsp</result>
   </action>
 </package>  
</struts>

Answer 6

是包没导入的问题，这个可以org/apache/commons/lang3/StringUtils提示，右键项目Build Path-----Configure Build Path...看看jar包有没有导错的，重复的，检查一下呗
