struts2 validation入门

 
阅读更多

好长时间没做struts2项目了，最近在做的时候在带select的数据校验这块居然卡壳了，所以写了个小例子，收藏起来。

用到的jar：

  1. commons-fileupload-1.2.1.jar
  2. commons-io-1.3.2.jar
  3. freemarker-2.3.15.jar
  4. jstl.jar
  5. ognl-2.7.3.jar
  6. standard.jar
  7. struts2-core-2.1.8.1.jar
  8. xwork-core-2.1.6.jar

jsp页面代码：

<%@ page language="java" contentType="text/html; charset=UTF-8"	pageEncoding="UTF-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<style type="text/css">
.errorMessage{

}
</style>
<title>添加人员</title>
</head>
<body>
	<h3>添加人员</h3>
	<s:fielderror></s:fielderror>
	<s:action name="initBooks" var="initBooks" />
	<s:action name="initCities" var="initCities" />
	<s:form id="form" namespace="/person" action="save" method="post">
		编号：<input type="text" id="personId" name="person.id" value="${person.id }"/></br>
		姓名：<input type="text" id="personName" name="person.name"  value="${person.name }"/></br>
		<s:select list="#initCities.cities" id="cityId" name="person.city.id" listKey="id" listValue="name" label="籍贯" value="%{person.city.id}">			
		</s:select>
		
		<s:select list="#initBooks.books" id="bookId" name="bookIds" listKey="id" listValue="name" label="读过的书" multiple="true">			
		</s:select>
		<input type="submit"/> <input type="reset"/>
	</s:form>
</body>
