这可能很简单，但我很难过。这是我正在尝试将csv文件加载到实体中。我找到了一个php插件，但无法弄清楚如何安装，所以我下载了插件，并将脚本读取到我的捆绑Acme \ StoreBundle中的csv文件，并实际将脚本（sfCsvReader.php）放在实体文件夹中捆绑当我尝试在网络上运行时，我收到以下错误
致命错误：第26行的/home/jan/symfonysandbox/src/Acme/StoreBundle/Controller/LoadCSVController.php中找不到类'Acme \ StoreBundle \ Controller \ sfCsvReader'
我的Controller文件如下
<?php
namespace Acme\StoreBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Acme\StoreBundle\Entity\Congress;
use Acme\StoreBundle\Entity\sfCsvReader;
use Symfony\Component\HttpFoundation\Response;
class LoadCSVController extends Controller
{
/**
* @Route("/load/{name}")
* @Template()
*/
public function indexAction()
{
$congress = new Congress();
$path = '~/Documents/congress.csv';
$reader = new sfCsvReader($path);
$reader->setSelectColumns('column_A, column_B');
$reader->open();
while ($data = $reader->read())
{
$congress->setTitle($data['column_A']);
$congress->setName($data['column_B']);
$em = $this->getDoctrine()->getManager();
$em->persist($congress);
$em->flush();
return new Response('Created congress id '.$congress->getId() .'for'.$congress->getTitle().'for'.$congress->getName());
}
$reader->close();
}
}
脚本调用
sfCsvReader

在调用脚本之前是否正在加载脚本？
尝试将以下代码添加到$loader->registerNamespaces(array(...数组声明中的 app / autoload.php ：
'SfCsvReader' => __DIR__.'/../src/Acme/StoreBundle/Entity/sfCsvReader.php',
之后，将 sfCsvReader.php 文件中的命名空间重命名为namespace SfCsvReader\sfCsvReader;，并将控制器中请求的命名空间替换为use SfCsvReader\sfCsvReader;。
这应该可以正常工作，但也许您应该将文件移动到更合适的目录，例如在项目的 vendor / sfCsvReader 目录中。
您可以按照Symfony 2.0文档中的建议操作。
自动加载信息位于以下链接The ClassLoader Component。
有关命名空间的更多信息，请参阅php.net。
