DWZ 动态生成树菜单

基本思路：父节点装到一个list，子节点装到另外一个list，遍历父节点，再从父节点里面遍历子节点，拼接相应的html字符串。实现方法如下

public Map<String,Object> queryAccountMenu(Integer id) {
		List<Resources> list = this.resourcesMapper.queryAccountMenu(id);
		StringBuffer sb = new StringBuffer();
		List<Resources> folderList = new ArrayList<Resources>();
		List<Resources> menuList = new ArrayList<Resources>();
		for(Resources r : list){
			if(r.getType()==0){
				folderList.add(r);
			}else if(r.getType()==2){
				menuList.add(r);
			}
		}
		for(Resources res : folderList){
			sb.append("<div class=\"accordionHeader\"><h2><span>Folder</span>" + res.getName() + "</h2></div>");
			sb.append("<div class=\"accordionContent\"><ul class=\"tree treeFolder\">");
			for(Resources menu : menuList){
				if(menu.getParentId() == res.getId()){
					sb.append("<li><a href=\"" + menu.getResUrl() + "\" target=\""+menu.getTarget()+"\" rel=\""+menu.getResKey()+"\">" + menu.getName() + "</a></li>");
				}
			}
			sb.append("</ul></div>");
		}
		HashMap<String, Object> map = new HashMap<String, Object>();
		map.put("menuHtml", sb.toString());
		map.put("menuList", list);
		return map;
	}
