根据手册，您必须捕获异常并重定向到正确的页面

这是我所做的，尽管我不一定对此感到高兴。

try {
        $this->Paginator->settings = $this->paginate;
        $widgets = $this->paginate();
    } catch (NotFoundException $e) {
        //Redirect to previous page
        $query = $this->request->query;
        $query['page']--;
        extract(Router::parse($this->request->here)); 
        $pass = empty($pass) ? '' : $pass[0]; 
        $this->redirect(array_merge(array('action' => $action, $pass), array('?' => $query))); 
    }

正如您所看到的，我减少了查询字符串中的页码，并继续重定向，直到到达一个有效的页面。我无法找到已知的页数来直接定向到最后一页。而且，我不喜欢提取URL的部分来重建它。在我的例子中，$pass参数可能存在，也可能不存在，这就是为什么我进行空检查。虽然这样做有效，我很欢迎大家提出如何做得更好的建议。

我所做的是在捕获NoFoundException时获取上一页，但通过指定的参数：

try {
    $records = $this->Paginator->paginate();
} catch (NotFoundException $e) {
    $this->request->params['named']['page']--;
    $records = $this->Paginator->paginate();
}

不过，我认为最好只是覆盖分页器组件。

这是可行的：
php类扩展了核心分页器组件{

/**
 * Overwrite to always redirect from out of bounds to last page of paginated collection.
 * If pageCount not available, then use first page.
 *
 * @param \Cake\Datasource\RepositoryInterface|\Cake\Datasource\QueryInterface $object The table or query to paginate.
 * @param array $settings The settings/configuration used for pagination.
 *
 * @throws \Cake\Network\Exception\NotFoundException
 *
 * @return \Cake\Datasource\ResultSetInterface Query results
 */
public function paginate($object, array $settings = [])
{
    try {
        $resultSet = parent::paginate($object, $settings);
    } catch (NotFoundException $exception) {
        $query = null;
        if ($object instanceof QueryInterface) {
            $query = $object;
            $object = $query->repository();
        }
        $alias = $object->alias();
        $lastPage = $this->request->params['paging'][$alias]['pageCount'] > 1 ? $this->request->params['paging'][$alias]['pageCount'] : null;

        $response = $this->getController()->redirect(['?' => ['page' => $lastPage] + $this->request->getQuery()]);

        // To be please PHPCS and tests, cannot be reached in production.
        if (PHP_SAPI === 'cli') {
            throw new NotFoundException('Redirect to ' . $response->getHeaderLine('Location') . ' for non-CLI.');
        } else {
            $response->send();
        }

        exit();
    }

    return $resultSet;
}

} ```
只要把它放在你的项目中，它会自动被使用，而不是核心的。适用于〈= 3. 4（第一页）和3. 5+（最后一页）。

使用try-catch进行分页并重定向到初始页。

try {
      $videos = $this->paginate($videos, $paginate);
    } catch (NotFoundException $e) { // Not existing page
      return $this->redirect([ // Remove pagination
        "controller" => $this->request->getParam('controller'),
        "action" => $this->request->getParam('action'),
      ]);
    }

要重定向到最后一页，请参阅@Kris的回答。
