无意中看到现在还有朋友在使用Struts-menu.真的感觉挺感慨的,想想自己两年前开始使用Struts-menu,刚开始的时候,真的是被搞的有点找不到头绪,但最终,我以struts-menu为基础,构建了基于数据库的树,树访问权限,用户系统等一系列的基础框架功能,这些,也是我在华罗庚软件基地有限公司工作期间所构建的主要框架模板,今天完整的写出来,供后来使用Struts-menu的朋友参考吧.

实现过程看上去会比较难看,您就凑合着点,后面还有Struts-menu到Dtree的转化,也就是说,我们使用Struts-menu的结构,可以直接转化为Dtree的结构,不需要任何额外的工作.

关于如何将Struts-menu增加到项目中,请参考Struts-menu的官方文档,这一块,官方文档有很详细的说明,我们目前主要使用Struts-menu的database menu.

１,关于数据库设计：

２.实体类
　实体类比较简单，按照上面的数据库结构进行映射就可以了,不再列出.
３.后台对Struts-menu数据的处理：这段处理比较混乱了一些,主要是以前项目中需要各种功能的树形结构,比如单选啊,多选啊,根据其它表结构生成树啊等等,所以增加了很多方法,增加的这些方法,最终可以实现,根据一条HQL或一个HQL名字生成一棵完整的树,在稍后的Action中会看到.

４.下面是一个在Aciton中构造单选树形结构的例子,很简单,只用调用上面的业务方法就可以了. 
public ActionForward radioTree(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response){
		String queryName=getHttp().getParameter(request, StringPool.QUERYNAME);
//		String nameAndId=getHttp().getParameter(request, StringPool.DATA_TREE_NAME_ID);
		Map treeMap=super.getService().getNewscategoryService().buildTreeForCheck(queryName, new String[]{"id","name","parentid"}, request);
		super.getHttp().setRequestAttribute(request, "root", treeMap.get(StringPool.DATA_DICTIONARY_TREE_PARENT_NODES));
		super.getHttp().setRequestAttribute(request, "trees", treeMap.get(StringPool.DATA_DICTIONARY_MENU_REPOSITORY));
		return mapping.findForward("radioTree");
	}


５.树形结构在页面上的显示.
　　在上面的Action方法中,我们已经将生成树所需要的数据放入了request中,那么在页面上,我们只需要按照Struts-menu官方文档中的说明进行操作就可以了.

以上就是使用Struts-menu根据数据库生成各种树形结构的主要代码,个人感觉Struts-menu在速度上面,优秀不是很大,但我们可以做其它种种操作来帮助它,比如我们可以将数据库中的数据一次性全部加载到内存中等.但是Strut-menu的database menu的扩展性,确实很不错,很多关于树的功能扩展,作者早已设计到了数据库中,比如更换节点的图片,更换节点的点击事件等,这些都可以在后台数据库中进行修改,而不需要改变我们的程序及网页.

大家一块试试吧,真的很不错哦

lz很奉献，表示支持；
不过看起来很复杂啊写的，我找到一个相对简单的xytree，
只是扩展性不如strutsMenu，自己修改变更比较麻烦
