如何进行非字段验证？
所有配置和短路验证中一致，仅需修改 验证器公共TestAgeValidation-validation.xml、validation.jsp 、validationa.jsp 及struts.xml
示例如下
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~分割线，我有来了~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
项目结构：
修改后的公共验证器
<span style="font-size:18px;"><!DOCTYPE validators PUBLIC
"-//Apache Struts//XWork Validator 1.0.2//EN"
"http://struts.apache.org/dtds/xwork-validator-1.0.2.dtd">
<validators>
<field name="age">
<!-- 类型转换验证 -->
<field-validator type="conversion" short-circuit="false" >
<message>类型转换错误</message>
</field-validator>
<!--
看看添加了短路验证 short-circuit="false"
若类型转换错误的时候，还会不会进行下面的 int整型验证
-->
<field-validator type="int" short-circuit="false">
<param name="min">1</param>
<param name="max">130</param>
<message key="error.int"></message>
</field-validator>
</field>
<validator type="expression">
<param name="expression"><![CDATA[password==password2]]></param>
<message>密码不一致</message>
</validator>
</validators></span>
新添加的 修改版的action错误消息提示

<#if (actionErrors?? && actionErrors?size > 0)>

<#if parameters.escape>${error!?html}<#else>${error!}</#if>

修改后的struts.xml
仅修改了，若验证成后的转发到success.jsp ，其他没动
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <!-- 配置全局的国际化资源文件 --> <constant name="struts.custom.i18n.resources" value="nihao"></constant> <package name="default" namespace="/" extends="struts-default"> <!-- 这个就是起烂笔头的作用 --> <interceptors> <interceptor-stack name="baiduStack"> <interceptor-ref name="paramsPrepareParamsStack"> <param name="prepare.alwaysInvokePrepare">false</param> </interceptor-ref> </interceptor-stack> </interceptors> <default-interceptor-ref name="baiduStack"/> <action name="testAge1" class="com.baidu.ActionValidation.TestAgeValidation"> <result>/success.jsp</result> <result name="input">/validation.jsp</result> </action> <action name="testAge2" class="com.baidu.ActionValidation.TestAgeValidation"> <result>/success.jsp</result> <result name="input">/validationa.jsp</result> </action> <!-- 中英文切换 是要使i18n 拦截器工作，因此是要使用一个action请求去调动其工作 --> <!-- index.jsp 通过action 转到 validation.jsp --> <action name="testVali" > <result>/validation.jsp</result> </action> <action name="testAge3" > <result>/validation.jsp</result> </action> </package> </struts>
validation.jsp

validationa.jsp
<span style="font-size:14px;"><%@ page language="java" contentType="text/html; charset=UTF-8"

<s:password name="password2" key="password2"></s:password>
