2.动态树状菜单:
地址栏访问方法http:
8080/study3/tree/showDynamicTreeAction.action
具体需要如下文件:
struts2的类库文件即与struts2相关的包文件,web.xml,struts.xml,动态树状菜单的显示页面treeExampleDynamic.jsp,
辅助显示页面:
dynamicTreeSelect.jsp,动态Action类文件DynamicTreeSelectAction.java，
提供数据的Bean类文件:
Category.java,
所需要的包文件如下:
commons-fileupload-1.2.1.jar
freemarker-2.3.12.jar
web.xml配置文件

在此struts.xml配置文件中我将动态树状菜单以及动态Ajax树状菜单的配置内容写在了这一个
配置文件中,其中动态树状菜单需要的action有dynamicTreeSelectAction,showDynamicTreeAction
动态Ajax树状菜单需要的action有dynamicTreeSelectAction,showDynamicAjaxTreeAction,
getNodes,这两个实例共用了提供数据的bean类文件Category.java文件.同时它们共用了
dynamicTreeSelectAction，但用于显示的Action类文件分别用了自己的Action类文件．

（注:
此文件就这三行代码负责将你选择的树状菜单相应结点信息如节点Id值与节点名称显示
在.jsp页面上．）
