在自定义路由类中使用自定义查找程序

Question

此自定义路由类可以工作，但是当我用自定义查找器替换查询时，它会返回错误：未知的查找器方法＆＃34;已发布＆＃34;。是不是可以在这里使用自定义查找器？

class ContentsRoute extends Route {

public function parse($url) {

    $params = parent::parse($url);
    if (!($params)) {
        return false;
    }

    $pages = Cache::read('pages');
    if ($pages === false) {
        $contents = TableRegistry::get('Contents');
        // custom finder 
        // $query = $contents->find('published');

        $query = $contents->find()
            ->select(['id', 'path', 'public'])
            ->where(['Contents.published' => 1]);

        $pages = $query->toArray();


        Cache::write('pages', $pages);
    }

    if (isset($pages[$url])) {
        $params['pass'] = array('path' => $url);
        return $params;
    }

    return false;

    }

}

//ContentsTable.php
public function findPublished(Query $query, array $options)
{
    $query = $this->find()
        ->select(['id', 'path', 'public'])
        ->where(['Contents.published' => 1]);
    return $query;
}
