 $dbNotice = M('notice');//实例化dbNotice对象
 $count  = $dbNotice->count();// 查询满足要求的总记录数
 $Page  = new \Think\Page($count,$count);// 实例化分页类 传入总记录数和每页显示的记录数(全部记录)
 $data = $dbNotice->order('create_time')->limit($Page->firstRow.','.$Page->listRows)->select();//获得所有记录
 $this->assign('notice',$data);//传给模板
 $this->show();
