**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="regist" class="org.crazyit.app.action.RegistAction">
                <result name="input">/WEB-INF/content/registForm.jsp</result>
                <result>/WEB-INF/content/show.jsp</result>
            </action>
    
            <action name="*">
                <result>/WEB-INF/content/{1}.jsp</result>
            </action>
        </package>
    </struts>

**三 领域模型**

package org.crazyit.app.domain;
    
    import java.util.*;
    
    
    public class User
    {
        private String name;
        private String pass;
        private int age;
        private Date birth;
    
        // name的setter和getter方法
        public void setName(String name)
        {
            this.name = name;
        }
        public String getName()
        {
            return this.name;
        }
    
        // 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;
        }
    
    }

**四 资源文件**

xwork.default.invalid.fieldvalue={0}字段无效
    name.requried=用户名必填！
    name.regex=用户名必须是字母和数字，且长度必须在4~25之间！
    pass.requried=用户名必填！
    pass.regex=用户名必须是字母和数字，且长度必须在4~25之间！
    age.range=年龄必须在${min}和${max}之间。
    birth.range=生日必须在${min}和${max}之间。
