???public List getTreelist(){ ???//设定树菜单的根 ???String ztree = "{ id:00, pId:0, name:‘要显示的根名,也可以从数据库取出‘, click:\"parent.setIframesrc()\" , open:true },"; ???List ztreeList = new ArrayList(); //从数据库获取所有菜单的信息 ???List menuList = this.getMenuList(); ???if(Collections.isNotEmpty(menuList)){ ????ztreeList.add(ztree); ????for (int i = 0; i < menuList.size(); i++) { ???????Menu menu = (Menu) menuList.get(i); //按照一定的格式拼接字符串，最后返回到jsp页面 ???????ztree = "{ id:"+menu.getMenuid()+", pId:"+menu.getParentid()+", name:\""+menu.getMenuname()+"\"," + ???????????"click:\"parent.setIframesrc(‘"+menu.getMenuid()+"‘)\"},"; ???????if (i+1 == menuList.size()) { ????????ztree = ztree.substring(0, ztree.lastIndexOf(",")); ???????} ???????ztreeList.add(ztree); ????} ???} ????return ztreeList; }3.然后从Action调用getTreelist(),并用"tree"的键值返回jsp页面，从jsp页面接收展示即可。
