struts2的输入验证框架(xml配置)

       此处为了简便起见和知识重复性的避免,暂不考虑类型转换问题。

第一步:(这一步和其他一样,这里从简)依旧是新建一个web project,命名为checkxml,导入struts2必须的包。在src目录下新建struts.xml,修改web.xml文件。
第二步:将index.jsp改名为reg.jsp(这个不是必须的,事实上也没有必要,此处只是为了便于称呼)。Input.jap的代码如下

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%@ taglib prefix="s"  uri="/struts-tags"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'index.jsp' starting page</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
  </head>

	<body>
		<s:form action="reg">
			<s:textfield name="username" label="username"></s:textfield>
			<s:password name="password" label="password"></s:password>
			<s:password name="repassword" label="repassword"></s:password>
			<s:textfield name="age" label="age"></s:textfield>
			<s:textfield name="birthday" label="birthday"></s:textfield>
			<s:textfield name="graduation" label="graduation"></s:textfield>

			<s:submit name="submit"></s:submit>
			<s:reset name="reset"></s:reset>
		</s:form>

	</body>
</html>


第二步:action
在src目录下新建新建包cn.edu.hdu.action 在其中新建一个RegAction.java文件
代码如下

package cn.edu.hdu.action;

import java.util.Calendar;
import java.util.Date;

import com.opensymphony.xwork2.ActionSupport;

public class RegAction  extends ActionSupport

{
		private String username;
		private String password;
		private String repassword;
		private int age;
		private Date birthday;
		private Date graduation;
		public String getUsername() {
			return username;
		}
		public void setUsername(String username) {
			this.username = username;
		}
		public String getPassword() {
			return password;
		}
		public void setPassword(String password) {
			this.password = password;
		}
		public String getRepassword() {
			return repassword;
		}
		public void setRepassword(String repassword) {
			this.repassword = repassword;
		}
		public int getAge() {
			return age;
		}
		public void setAge(int age) {
			this.age = age;
		}
		public Date getBirthday() {
			return birthday;
		}
		public void setBirthday(Date birthday) {
			this.birthday = birthday;
		}
		public Date getGraduation() {
			return graduation;
		}
		public void setGraduation(Date graduation) {
			this.graduation = graduation;
		}
		
		public String execute() throws Exception
		{
			return 	SUCCESS;
		}


			
			
		}
		
		



第三步:修改struts.xml文件 代码如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
 	"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" 
 	"struts.apache.org/dtds/struts-2.0.dtd">
          <struts>
					<package name="checkxml" extends="struts-default">
							<action name="reg" class = "cn.edu.hdu.action.RegAction">
									<result name="success">/success.jsp</result>
									<result name="input">reg.jsp</result>
							</action>
					</package>
</struts>



第四步: 在WebRoot目录下新建另一个视图 success.jsp 代码如下(此文件在这个效验中基本没有什么作用)

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'success.jsp' starting page</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->

  </head>
  
  <body>
    恭喜你  验证通过  </body>
</html>



最后一步,也是本节真正内容所在
在cn.edu.hdu.action目录下新建一个名字与action对应的xml文件
RagAction-validation.xml 代码如下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
        "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
        "//www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
        
        <!-- 框架校验部分 -->
<validators>
	<!-- 分别对每一个字段校验 -->
	<field name="username">
		<!-- 每一种校验标准 -->
		<field-validator type="requiredstring">
			<!-- field-validator下的一些属性标签  说白了 就是一些传入函数的参数 -->
			<param name="trim">true</param>

			<!-- 出错信息 -->
			<message>username is required</message>
		</field-validator>

	</field>
	<!-- 一下都和username类似 将不做批注 -->
	<field name="password">

		</field-validator>

		<field-validator type="stringlength">
			<param name ="minLength">6</param>
			<param name ="maxLength">10</param>
			<message>
				password should between ${minLength} to ${maxLength}
			</message>
		</field-validator>

	</field>



	<field name="repassword">
		<!-- 每一种校验标准 -->
		<field-validator type="requiredstring">
			<!-- field-validator下的一些属性标签  说白了 就是一些传入函数的参数 -->
			<param name="trim">true</param>

		</field-validator>

		<field-validator type="stringlength">
			<param name ="minLength">6</param>
			<param name ="maxLength">10</param>
			<message>
				repassword should between ${minLength} to ${maxLength}
			</message>
		</field-validator>

	</field>



	<field name="age">
		<!-- 每一种校验标准 -->

		<field-validator type="int">
			<param name ="min">1</param>
			<param name ="max">150</param>
			<message>age should between ${min} to ${max}</message>
		</field-validator>

	</field>





	<field name="birthday">
		<!-- 每一种校验标准 -->
		<field-validator type="requiredstring">
			<!-- field-validator下的一些属性标签  说白了 就是一些传入函数的参数 -->
			<param name="trim">true</param>

			<!-- 出错信息 -->
			<message>birthday is required</message>
		</field-validator>

		<field-validator type="date">
			<param name ="min">2000-1-1</param>
			<param name ="max">2010-12-31</param>
			<message>birthday should between ${min} to ${max}</message>
		</field-validator>

	</field>


	<field name="graduation">
		<!-- 每一种校验标准 -->
		<field-validator type="requiredstring">
			<!-- field-validator下的一些属性标签  说白了 就是一些传入函数的参数 -->
			<param name="trim">true</param>

			<!-- 出错信息 -->
			<message>graduation is required</message>
		</field-validator>

		<field-validator type="date">
			<param name ="min">2000-1-1</param>
			<param name ="max">2010-12-31</param>
			<message>
				graduation should between ${min} to ${max}
			</message>
		</field-validator>

	</field>

</validators>
