基于XML配置方式实现输入校验

在JSP页面中导入<%@ taglib uri="/struts-tags" prefix="s" %>标签

在页面中显示信息用验证的信息:<s:fielderror/>

在action中创建一个继承ActionSupport的UserInfoAction.java类

然后再action包下创建一个UserInfoAction-validation.xml

[html]
<SPAN style="FONT-SIZE: 14px"><?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.3//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.3.dtd">

在STRUTS.XML中配置

[html]
<SPAN style="FONT-SIZE: 14px"><?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
<struts>
    <package name="base" namespace="" extends="struts-default">
        <action name="user_*" method="{1}" class="action.UserInfoAction">
            <result name="ok">/index.jsp</result>
            <result name="input">/index.jsp</result>
        </action>
    </package>
</struts></SPAN>

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
