Answer 3

这是我的RegistAction-validation.xml<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE  validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
<field name="username">
<field-validator type="requiredstring" short-circuit="true">
<param name="trim">true</param>
<message>用戶名不能為空！</message>
</field-validator>
<field-validator type="regex">
<param name="expression"><![CDATA[(\w{4,25})]]></param>
<message>用戶名只能是字母和數字，且長度必須在4到25之間！</message>
</field-validator>
</field>
<field name="password1">
<field-validator type="requiredstring" short-circuit="true">

</field-validator>
<field-validator type="regex">

<message>密碼只能是字母和數字，且長度必須在4到25之間！</message>
</field-validator>
</field>
<field name="password2">
<field-validator type="requiredstring" short-circuit="true">

</field-validator>
<field-validator type="regex" short-circuit="true">
<param name="expression">![CDATA[(\w{4,25})]]></param>

<field-validator type="fieldexpression">
<param name="expression"><![CDATA[(password2==password1)]]></param>

</field-validator>
</field>
<field name="address">
<field-validator type="requiredstring" short-circuit="true">
<param name="trim">true</param>
<message>郵箱不能為空！</message>
</field-validator>
<field-validator type="email">
<message>郵箱格式不正確！</message>
</field-validator>
</field>
</validators>这是jsp文件：<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<%@taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

</head>
<body>
<h2>注冊信息：</h2><s:form action="regist" validate="true">

Answer 4

一般放到和要验证的.class文件在同一目录下,也就是编译后要在同一目录下

Answer 5

先看看编译后xml文件是否跟action.class文件是否在同一目录下，看你上面的代码是没错误的。

Answer 6

 <action name="regist" class="registAction">
把registAction这个换成RegistAction，好久不用web了，不知道对不对
