thinkphp5 初始化灵活方法

<?php
namespace app\test\controller;
use think\Controller;

class YangZheWei extends Controller
{
    protected $beforeActionList = [
        'than',
        'first' => ['except' => 'one'], //one 方法不可用
        'san' => ['only' => 'three,two'], //只能three和two
    ];

    protected function first()
    {
        echo '初始111<br>';
    }
    protected function than()
    {
        echo '初始222<br>';
    }
    protected function san()
    {
        echo '初始333<br>';
    }
    public function one()
    {
        return '111<br>';
    }
    public function two()
    {
        return '222<br>';
    }
    public function three()
    {
        return '333<br>';
    }
