struts1.1中validation校验框架的应用

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>

---------------------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/u5c11/u4e8e {1} /u4e2a/u5b57.

   errors.maxlength={0} /u4e0d/u80fd/u591a/u4e8e {1} /u4e2a/u5b57.

   errors.invalid={0} /u5fc5/u987b/u5b9a/u4e49.

   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>

<form method="post" action="./loginAction.do" onsubmit="return validateLoginForm(this)">

<input  type="text" name="userName" /><br >

<input  type="passWord" name="passWord"/><br >

<input type="submit" name="Submit" value="Submit">

<input type="reset" value="Reset">

</form>

<html:javascript  formName="loginForm" dynamicJavascript="true" staticJavascript="false"/>

<!--

此处将加载脚本动态验证,验证函数由校验框架,validator-rules.xml提供

-->

<script type="text/javascript"

      src="<html:rewrite page="/staticJavaScript.jsp"/>"></script>

<!--

此处通过外部文件加载静态脚本验证

-->

 

</body>

</html>

 

--------------------------wel.jsp欢迎页面,校验通过视图分发至此页面-------------------------------

<%@ page contentType="text/html; charset=GB18030" import="validate2.*,org.apache.struts.validator.DynaValidatorForm"%>

<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>

<%

DynaValidatorForm loginForm=(DynaValidatorForm)request.getAttribute("loginForm");

 

%>

<html>

<head>

<title>

wel

</title>

</head>

<body bgcolor="#ffffff">

<h1>

<%=(String)loginForm.get("userName")%>

<!--

由于是动态Form, DynaValidatorForm不提供属性的get和set方式,使用通用的get方法取值

-->

</h1>

 

</body>

</html>

------------------------StaticJavaScript.jsp被login.jsp调用文件,实现静态脚本验证----------------

<%@ page language="java" %>

<%@ page contentType="application/x-javascript"%>

<!--

注意contentType文档类型

-->

<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>

<html:javascript dynamicJavascript="false" staticJavascript="true"/>
