struts1.1中validation校验框架的应用有哪些？
校验框架加载:
在建立web模型时选中struts1.1中的validation,此事例以登录模块为例实现struts校验框架的脚本验证以及form验证,包括资源文件的国际化
1. struts配置文件
-------------------------------------structs-config.xml-----------------------------------------------------------
<?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="loginForm" type="org.apache.struts.validator.DynaValidatorForm" >
<form-property name="userName" type="java.lang.String">
</form-property>
<form-property name="passWord" type="java.lang.String">
</form-property>
</form-bean>
<!--
此处为动态formBean,此XML加载时加载此form,注意其type为DynaValidarorForm,若不使用动态Form也需继承此类.
-->
</form-beans>
<action-mappings>
<action input="/login.jsp" name="loginForm" path="/loginAction" scope="request" type="validate2.LoginAction" validate="true" >
<forward name="success" path="/wel.jsp">
</forward>
<!--
forword设置转向,应用于action中的mapping.findForword()
-->
</action>
</action-mappings>
<message-resources parameter="ApplicationResources" />
<!--
资源文件声明
-->
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml" />
</plug-in>
<!--
plug-in声明的校验框架的插件
-->
</struts-config>
------------------------------------web.xml------------------------------------------------------------------------

---------------------validator-rules.xml校验框架自动生成无需修改在此不列出代码-----------
-----------------------validator.xml内容空白,需手动填写,用于声明校验方式及规则------------
<?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="loginForm">
<field property="userName" depends="required">
<!--
property为校验的对象名称,depend为校验方式名称,required代表必填,
相应的校验方式名称在validator-rules中声明
-->
<arg0 key="userName.text"/>
<!--
处理信息参数,处理信息见资源文件,参数值也取自资源文件中键值为userName.text
的字符串
-->
</field>
<!--
-->
<field property="passWord" depends="required,maxlength">
<!--
多种校验用,分隔
-->
<arg0 key="passWord.text"/>
<arg1 key="${var:maxlength}" name="maxlength" resource="false"/>
<!--
key用表达式取某变量值,name为校验方式,resourse为是否从资源文件中取值
-->
<var>
<var-name>maxlength</var-name>
<var-value>6</var-value>
</var>
<!--
此处声明了上面用到的变量
-->
</field>
</form>
</formset>
</form-validation>
----------------------ApplicationResources.properties默认资源文件,复制validator-rules.xml中的注释即可,记录错误处理信息语句,可修改-------------------
errors.required={0} is required.
errors.minlength={0} can not be less than {1} characters.
errors.maxlength={0} lecky {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 an invalid credit card number.
errors.email={0} is an invalid e-mail address.
userName.text=userName
passWord.text=password
---------------------------------------ApplicationResources_zh.properties中文资源文件,将需求的信息由中文转置为ascii码存储-----------------------------------------------------------------------
errors.required={0} /u5fc5/u987b/u586b/u5199.
errors.minlength={0} /u4e0d/u80fd/u
errors.maxlength={0} /u4e0d/u80fd/u
errors.invalid={0} /u5fc5/u987b/u5b
errors.byte={0} must be a byte.
errors.short={0} must be a short.
errors.integer={0} /u5fc5/u987b/u
errors.long={0} must be a long.
errors.float={0} must be a float.
errors.double={0} must be a double.
errors.date={0} /u4e0d/u
errors.range={0} is not in the range {1} through {2}.
errors.creditcard={0} is an invalid credit card number.
errors.email={0} /u4e0d/u
userName.text=/u7528/u6237/u540d
passWord.text=/u5bc6/u7801
2. Action
此处与无验证框架的Aciton基本相同
-------------------------------LoginAction.java------------------------------------------------------------------
package validate2;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.Action;
import org.apache.struts.validator.DynaValidatorForm;
public class LoginAction extends Action {
public ActionForward execute(ActionMapping actionMapping,
ActionForm actionForm,
HttpServletRequest servletRequest,
HttpServletResponse servletResponse) {
DynaValidatorForm loginForm = (DynaValidatorForm) actionForm;
return actionMapping.findForward("success");
}
}
3. jsp页面
-------------------------------Login.jsp,登录页面,提交两个对象给LoginAction-------------------------
<%@ page contentType="text/html; charset=GB18030" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<html>
<head>
<title>
login
</title>
</head>
<body bgcolor="#ffffff">
<h1>
<font color="red">
<html:errors/>
<!--
此处为错误处理信息
-->
</font>
</h1>
