我们刚才已经写好model了，那么这里直接来调用下他即可：
public function lists(){
$mod = D('Category')->catTree();
$this -> assign('mod',$mod);
$this->display();
}
然后在模版里面进行遍历即可：
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>后台管理</title>
<link rel="stylesheet" type="text/css" href="__PUBLIC__/Admin/css/common.css"/>
