struts2实现客户端验证怎么做

来源：互联网发布：游戏编程入门编辑：程序博客网时间：2024/04/29 20:41

前不久，我自己做了一个客户端验证的项目，搞了我好久才把他搞出来，我觉得这个东西吗，要拿过来和大家分享一下。

下面是我的struts.xml的源码：

<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd" >
<struts>
<package name="validation" extends="struts-default" >
        <interceptors>
            <interceptor-stack name="crudStack">
                 <interceptor-ref name="checkbox" />
                 <interceptor-ref name="params" />
                 <interceptor-ref name="static-params" />
                 <interceptor-ref name="defaultStack" />
            </interceptor-stack>
        </interceptors>
  
  <action name="Login" class="cn.dxyy.web.LoginAction" method="input">

<result name="success" type="freemarker">
    <param name="location">/welcome.ftl</param>
   </result>
   
   <result name="error" type="dispatcher">
    <param name="location">/error.jsp</param>
   </result>
   <result name="input">/Login.jsp</result>

</action>
</package>
</struts>
下面是我的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  </filter-class>
</filter>
<filter-mapping>
  <filter-name>struts</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
<servlet id="dwr">
  <servlet-name>dwr</servlet-name>
  <servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>dwr</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>

<welcome-file-list>
<welcome-file>Login.jsp</welcome-file>
</welcome-file-list>

</web-app>
下面是我的dwr.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN"
"http://www.getahead.ltd.uk/dwr/dwr10.dtd">

    <signatures>
        <![CDATA[
        import java.util.Map;
        import org.apache.struts2.validators.DWRValidator;

DWRValidator.doPost(String, String, Map<String, String>);
        ]]>
    </signatures>
</dwr>

下面是我的validator.xml

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE form-validation PUBLIC
     "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.3.0//EN"
     "http://jakarta.apache.org/commons/dtds/validator_1_3_0.dtd">
<form-validation>

    <global>
        
    </global>
   <formset>
        
        <form name="gangsterForm">
            <field
                property="age"
                depends="required">
                    <msg name="required" key="The age is required" resource="false"/>
            </field>
        </form>
    </formset>
</form-validation>

下面是我的几个jsp页面

<%@ page language="java" pageEncoding="GBK"%>
<%@ taglib prefix="s" uri="/struts-tags" %>

   登录
  <s:form cssStyle="border: 1px solid green;" method="post" namespace="/" action="Login" validate="true">
  <s:textfield name="user.username" label="姓名"   />
                 <s:password name="user.password" label="密码"   />
  <s:submit />

</s:form>
    </center>
</body>
</html>

                                                 login.jsp

<%@ page language="java" pageEncoding="GBK"%>
<html>
<head>
  <title>错误</title>
</head>
<body>
  <DIV align="center">
   <h3>来到这里就是出错啦</h3>
  </DIV>
</body>
</html>
                                           error.jsp

还有一个最重要的文件，在这个客户端验证里，名字必须是action的名字加上validator.xml,要不就会报错

<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">

<validators>
    <field name="user.username">
        <field-validator type="requiredstring">
            <message>You must enter a name</message>
        </field-validator>
    </field>
    <field name="user.password">
<field-validator type="requiredstring">
  <message>必须填写</message>
</field-validator>
        <field-validator type="stringlength">
            <param name="maxLength">100</param>
            <param name="minLength">5</param>
            <param name="trim">true</param>
            <message>必须5-100之内的字符长度</message>
        </field-validator>
    </field>

</validators>
