三种使用Struts 2实现树状菜单的方式.docx

三种使用Struts 2实现树状菜单的方式Struts2树状菜单实现一.概要:这篇文章是自己在学习struts2时从struts2的官方英文文档实例中整理出来的，此处介绍三种Struts2树状菜单的实现方式分别是:静态，动态，动态Ajax三种方式.以下实例均在windowsXpsp2+Struts2+MyEcliplse6.01+Tomcat6.0.14+JDK1.6.0_03下调试通过,项目名称为study3,包名为com.zhang.struts3这三种实例用到的包文件(,jar包)如下:commons-io-1.3.2.jarognl-2.6.11.jarstruts2-core-2.1.2.jarstruts2-dojo-plugin-2.1.2.jarxwork-2.1.1.jar二.具体实现1.静态指单独使用struts2的tree标签脚本实现的．如以下文件treeStatic.jsp此文件不需要任何Action类支持,启动Tomcat后在地址栏中输入::8080/study3/treeStatic.jsp:8080/study3/treeStatic.jsp就行．*****treeStatic.jsp********************************************************************%@?page?language=java?import=java.util.*?pageEncoding=UTF-8%?%@taglib?prefix=s?uri=/struts-tags%?%@?taglib?prefix=sx?uri=/struts-dojo-tags%?%?String?path?=?request.getContextPath();?String?basePath?=?request.getScheme()?+?://?+?request.getServerName()?+?:?+?request.getServerPort()?+?path?+?/;%?html??head??sx:head?/??base?href=%=basePath%??titleTree?Example(Static)/title??meta?http-equiv=content-type?content=text/html;?charset=UTF-8??script?language=JavaScript?type=text/javascript??dojo.event.topic.subscribe(treeSelected,?function?treeNodeSelected(node)?{?dojo.io.bind({?url:?s:url?value=/info/staticTreeAction.action/?nodeId=+node.node.title,?load:?function(type,?data,?evt)?{?var?divDisplay?=?dojo.byId(displayIt);?divDisplay.innerHTML=data;?},?mimeType:?text/html?});?});/script??/head??body??div?id=displayIt??Please?click?on?any?node?on?the?tree.?/div??div?style=float:?left;?margin-right:?50px;??sx:tree?label=软件工程?templateCssPath=/struts/tree.css??showRootGrid=true?showGrid=true?treeSelectedTopic=treeSelected??sx:treenode?label=开发工具??sx:treenode?label=java?id=grandchild1Id?/??sx:treenode?label=c++?id=grandchild2Id?/??sx:treenode?label=delphi?id=grandchild3Id?/??/sx:treenode??sx:treenode?label=编程思想?id=child2Id?/??sx:treenode?label=数据结构?id=child3Id?/??sx:treenode?label=设计模式?id=child4Id?/??sx:treenode?label=相关框架插件?id=child5Id??sx:treenode?label=Dojo?id=gChild1Id?/??sx:treenode?label=Hibernate?id=gCh
