使用Struts校验框架完成输入校验

首先我们看下，项目搭建文件布局，如下图：

（图一）

接下来看下，registerForm.jsp在浏览器上的执行页面效果图：

（图二）

附属源码如下：

 1 <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
 2 
 3 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
 4 <html>
 5   <head>
 6     
 7     <title>My JSP 'index.jsp' starting page</title>
 8 
 9   </head>
10   
11   <body>
12             <form action="login" method="post">
13                        <table align="center" border="1">
14                                  <caption><h2>用户登陆</h2></caption>
15                                  <tr><td align="right">用户名：</td><td><input type="text" name="username" /></td></tr>
16                                  <tr><td  align="right">密码：</td><td><input type="password" name="password" /></td></tr>
17                                  <tr><td align="center" colspan="2"><input type="submit" value="提交"/>&nbsp;&nbsp;<input type="reset" value="重置"/></td></tr>
18                        </table>
19             </form>
20   </body>
21 </html>

那么校验效果如何，接下来看下如下两站图的说明：

以下是图一中其他文件的源码：

1）RegisterAction.java

 1 package com.abc.action;
 2 import java.util.Date;
 3 import com.opensymphony.xwork2.ActionSupport;
 4 public class RegisterAction extends ActionSupport {

13                 }
14                 public void setUname(String uname) {
15                     this.uname = uname;

23                 public String getReupassword() {
24                     return reupassword;
25                 }
26                 public void setReupassword(String reupassword) {
27                     this.reupassword = reupassword;
28                 }
29                 public int getUage() {
30                     return uage;
31                 }
32                 public void setUage(int uage) {
33                     this.uage = uage;
34                 }
35                 public Date getUbirth() {
36                     return ubirth;
37                 }
38                 public void setUbirth(Date ubirth) {

40                 }

45                     this.uemail = uemail;
46                 }
47               public String execute()  throws Exception{

5)registerOk.jsp脚本很简单就不贴了，大体就是返回成功的提示文本可以随意发挥！
