tp3.2的这段代码，用tp5.1的写法

Question

    //魔术方法
    public function __call($method, $args) {
        if (!require_cache("{$this->addonPath}Controller/AdminController.class.php")) {
            E("插件database实例化错误！");
        }
        $object = \Think\Think::instance("\\Addon\\database\\Controller\\AdminController");
        return $object->$method($args);
    }

就是用TP5.1怎么写
