注：本文系做者在看了浪曦的風中葉老師的struts2視頻的我的總結，但願能幫助廣大struts2的初學者。

此處爲了簡便起見和知識重複性的避免，暫不考慮類型轉換問題。

第一步：（這一步和其餘同樣，這裏從簡）依舊是新建一個web project，命名爲checkxml，導入struts2必須的包。在src目錄下新建struts.xml，修改web.xml文件。
第二步：將index.jsp更名爲reg.jsp（這個不是必須的，事實上也沒有必要，此處只是爲了便於稱呼）。Input.jap的代碼以下

html

Jsp代碼 java

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%> web
<% apache
String path = request.getContextPath(); 框架
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; jsp
%> 函數
<%@ taglib prefix="s" uri="/struts-tags"%> ui
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> this
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<s:form action="reg">
<s:textfield name="username" label="username"></s:textfield>
<s:password name="password" label="password"></s:password>
<s:password name="repassword" label="repassword"></s:password>
<s:textfield name="age" label="age"></s:textfield>
<s:textfield name="birthday" label="birthday"></s:textfield>
<s:textfield name="graduation" label="graduation"></s:textfield>
<s:submit name="submit"></s:submit>
<s:reset name="reset"></s:reset>
</s:form>
</body>
</html>

第二步：action
在src目錄下新建新建包cn.edu.hdu.action 在其中新建一個RegAction.java文件
代碼以下

Java代碼

package cn.edu.hdu.action;
import java.util.Calendar;
import java.util.Date;
import com.opensymphony.xwork2.ActionSupport;
public class RegAction extends ActionSupport
{
private String username;
private String password;
private String repassword;
private int age;
private Date birthday;
private Date graduation;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getRepassword() {
return repassword;
}
public void setRepassword(String repassword) {
this.repassword = repassword;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
public Date getGraduation() {
return graduation;
}
public void setGraduation(Date graduation) {
this.graduation = graduation;
}
public String execute() throws Exception
{
return SUCCESS;
}
}

第三步：修改struts.xml文件代碼以下

Xml代碼

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="checkxml" extends="struts-default">
<action name="reg" class = "cn.edu.hdu.action.RegAction">
<result name="success">/success.jsp</result>
<result name="input">reg.jsp</result>
</action>
</package>
</struts>

第四步：在WebRoot目錄下新建另外一個視圖 success.jsp 代碼以下（此文件在這個效驗中基本沒有什麼做用）

Jsp代碼

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'success.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
恭喜你驗證經過 </body>
