struts2服务端验证

    一个简单的strutseb2服务器端验证,竟然花了一个多小时才完成。。。。找了半天原来是一个方法名写错了。。笔误。。
把getUsername().写成了getUserame(),然后一直取不出username的值。。。。
    1.注册页面（register.jsp）
   

<% @ page language="java" contentType="text/html; charset=GBK" %>
<% @taglib prefix="s" uri="/struts-tags" %>

< html >

< head >

< meta  http-equiv ="Content-Type"  content ="text/html; charset=gb2312" />

< title > 请输入您的注册信息 </ title >

</ head >


< body >
< H1 > 请输入您的注册信息 </ H1 >
< s:fielderror />
< FORM  METHOD ="POST"  ACTION ="regist.action" >
    用户名： < INPUT  TYPE ="text"  NAME ="username" >< br >
    密 &nbsp;&nbsp; 码： < INPUT  TYPE ="text"  NAME ="pass" >< br >
    年 &nbsp;&nbsp; 龄： < INPUT  TYPE ="text"  NAME ="age" >< br >
    生 &nbsp;&nbsp; 日： < INPUT  TYPE ="text"  NAME ="birthday" >< p >
     < INPUT  TYPE ="submit"  value ="注册" >
</ FORM >


</ body >

</ html >

(2)Action类(RegisterAction.java)

package  my;
import  com.opensymphony.xwork2.ActionSupport;
import  java.util.Date;
public   class  RegisterAction  extends  ActionSupport
{
    private String username;
    private String pass;
    private int age;
    private Date birthday;
    public void setUsername(String username)
    {
        this.username = username;
    }
    public String getUsername()
    {
        return this.username;
    }

    public void setPass(String pass)
    {
        this.pass = pass;
    }
    public String getPass()
    {
        return this.pass;
    }
    public void setAge(int age)
    {
        this.age = age;
    }
    public int getAge()
    {
        return this.age;
    }
    public void setBirthday(Date birthday)
    {
        this.birthday = birthday;
    }
    public Date getBirthday()
    {
        return this.birthday;
    }
    public String execute()throws Exception 
    {
        return SUCCESS;
    }
}
