**一 视图**

1 form.jsp

<%@ page contentType="text/html; charset=GBK" language="java" errorPage="" %>
    <%@taglib prefix="s" uri="/struts-tags"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

        </td></tr>
    </s:form>
    
    </body>
    
    </html>

**二 配置文件**

<?xml version="1.0" encoding="GBK"?>
    <!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
        "http://struts.apache.org/dtds/struts-2.3.dtd">
    <struts>
        <constant name="struts.i18n.encoding" value="GBK"/>
    
        <package name="lee" extends="struts-default">
            
            <action name="*Pro" class="org.crazyit.app.action.RegistAction"
                method="{1}">
                <result name="input">/WEB-INF/content/form.jsp</result>
                <result>/WEB-INF/content/show.jsp</result>
            </action>
            <action name="*">
                <result>/WEB-INF/content/{1}.jsp</result>
            </action>
        </package>
    </struts>

**三 action**

1 BaseAction

package org.crazyit.app.action;
    
    import com.opensymphony.xwork2.ActionSupport;
    import java.util.*;
    
    
    public class BaseAction extends ActionSupport
    {
        private String name;
    
        // name的setter和getter方法
        public void setName(String name)
        {
            this.name = name;
        }
        public String getName()
        {
            return (this.name);
        }
    }

2 RegistAction

package org.crazyit.app.action;
    
    import com.opensymphony.xwork2.ActionSupport;
    import java.util.*;
    
    public class RegistAction extends BaseAction
    {
        private String pass;
        private int age;
        private Date birth;
    
        // pass的setter和getter方法
        public void setPass(String pass)
        {
            this.pass = pass;
        }
        public String getPass()
        {
            return this.pass;
        }
    
        // age的setter和getter方法
        public void setAge(int age)
        {
            this.age = age;
        }
        public int getAge()
        {
            return this.age;
        }
    
        // birth的setter和getter方法
        public void setBirth(Date birth)
        {
            this.birth = birth;
        }
        public Date getBirth()
        {
            return this.birth;
        }
        public String regist()
        {
            return SUCCESS;
        }
        public String login()
        {
            return SUCCESS;
        }
    }

**四 资源文件**

xwork.default.invalid.fieldvalue={0}字段无效
    name.requried=您必须输入用户名!
    name.regex=您输入的用户名只能是字母和数组，且长度必须在4到25之间!
    pass.requried=您必须输入密码!
    pass.regex=您输入的密码只能是字母和数组，且长度必须在4到25之间!
    age.range=您的年龄必须在${min}和${max}之间!
    birth.range=您的生日必须在${min}和${max}之间!
    nameexp=用户名和密码必须相同

**五 校验文件**
