Struts1.2中的validation验证框架的实现步骤（转帖）步骤：1 环境配置：首先要为struts加入Validator支持lib包

Struts1.2中的validation验证框架的实现步骤（转帖）
步骤：

1 环境配置：首先要为struts加入Validator支持
lib包：加入validator所需的jar包
配置文件：struts-config.xml里加入

<plug-in className="org.apache.struts.validator.ValidatorPlugIn">    <set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml" />  </plug-in>

这里所需的validator-rules.xml和validation.xml也需要放到/WEB-INF/下

2 配置actionForm
2.1 修改Form基类：将actionForm继承的基类改为ValidatorForm
2.2 配置struts-config.xml文件：把要验证的form的validator属性设为true

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd"><struts-config>  <form-beans>    <form-bean name="userForm" type="com.satesoft.test.UserForm" />  </form-beans>  <action-mappings>    <action input="/index.jsp" name="userForm" path="/show" scope="request" type="com.satesoft.test.ShowAction" validate="true">      <forward name="forward" path="/show.jsp" />    </action>  </action-mappings>  <message-resources parameter="ApplicationResources" />  <plug-in className="org.apache.struts.validator.ValidatorPlugIn">    <set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml" />  </plug-in></struts-config>

注意：一定要配置对应的Action里的input属性，否则struts找不到要返回的路径

2.3 配置validator.xml文件：在validation.xml里加入对要验证的actionform的定义

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE form-validation PUBLIC "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.0//EN" "http://jakarta.apache.org/commons/dtds/validator_1_0.dtd"><form-validation>  <formset>    <form name="userForm">      <field property="name" depends="required">        <arg0 key="user.name.required"/>      </field>    </form>  </formset></form-validation>

这里同时要配置的还有消息资源。在资源文件中加入上述配置文件中所需的消息

errors.header=<H3><font color="blue">errors</font><br>errors.footer=<p></p>errors.required={0} is required.errors.minlength={0} cannot be less than {1} characters.errors.maxlength={0} cannot be greater than {1} characters.errors.invalid={0} is invalid.errors.byte={0} must be a byte.errors.short={0} must be a short.errors.integer={0} must be an integer.errors.long={0} must be a long.errors.float={0} must be a float.errors.double={0} must be a double.errors.date={0} is not a date.errors.range={0} is not in the range {1} through {2}.errors.creditcard={0} is not a valid credit card number.errors.email={0} is an invalid email addressuser.name.required=user name

2.4 配置作为input的jsp页面：

<%@ page contentType="text/html; charset=GBK" %><%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %><html><head><title>index</title></head><body bgcolor="#ffffff"><html:form action="show.do" method="post">  <html:text property="name"/>  <html:submit title="确定"/>  <html:cancel title="取消">  </html:cancel></html:form><html:errors/></body></html>

如果需要加入javascript支持，则：

<%@ page contentType="text/html; charset=GBK" %><%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %><html><head><title>index</title></head><body bgcolor="#ffffff"><html:form action="show.do" method="post" onsubmit="return validateUserForm(this);">  <html:text property="name"/>  <html:submit title="确定"/>  <html:cancel title="取消">  </html:cancel></html:form><html:javascript formName="userForm"/></body></html>

注意：onsubmit里的validatorUserForm要和下面的formName里的名字一致，只不过首字母大写
