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;
}
