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">
        <!--配置一个名为*Pro的Action，
            对应的处理逻辑为RegistAction的{1}方法-->
        <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
