Question

希望你能帮助我。我在Linux上使用symfony 3.4。当我运行我的应用程序时，我有下一个错误：

致命错误：未捕获 Doctrine \ Common \ Persistence \ Mapping \ MappingException：该类＆＃39;的appbundle \实体\作业＆＃39;在配置的链中找不到名称空间 /var/www/html/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/MappingException.php:37 堆栈跟踪：＃0 /var/www/html/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/Driver/MappingDriverChain.php(112）：学说\ COMMON \持久性\制图\ MappingException :: classNotFoundInNamespaces（＆＃39;的appbundle \ Entit ...＆＃39 ;, 数组）＃1 /var/www/html/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataFactory.php(151）：教义\共同\持久性\映射\驱动\ MappingDriverChain-＆GT; loadMetadataForClass（＆＃39;的appbundle \ Entit ...＆＃39 ;, 对象（Doctrine \ ORM \ Mapping \ ClassMetadata））＃2 /var/www/html/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php(332）：教义\ ORM \映射\ ClassMetadataFactory-＆GT; doLoadMetadata（对象（学说\ ORM \映射\ ClassMetadata）， NULL，false，Array）＃3 / var / www / html / vendor / doctrine / orm / lib / Doctrine / 在/var/www/html/vendor/twig/twig/lib/Twig/Cache/Filesystem.php上第57行

我使用命令

创建了一个名为Job的实体

php bin / console doctrine：generate：entity

它创建了实体和存储库没有任何问题。在此之后我更新了数据库

php bin / console doctrine：schema：update --force

到目前为止一切顺利。现在我开始使用控制器：

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use AppBundle\Entity\Job;
use AppBundle\Entity\User;

use Symfony\Component\HttpFoundation\Response;
use Doctrine\ORM\EntityManagerInterface;

class DefaultController extends Controller
{
    /**
     * @Route("/", name="homepage")
     */
    public function indexAction(Request $request)
    {

        $em = $this->getDoctrine()->getManager();

        $job = new Job();

        $job->setName('PHP');
        $job->setDescription('Description');
        $job->setCategory('IT');
        $job->setLocation('London');



        $em->persist($job);
        $em->flush();

        // replace this example code with whatever you need
        return $this->render('default/index.html.twig', [
            'base_dir' => realpath($this->getParameter('kernel.project_dir')).DIRECTORY_SEPARATOR,
        ]);
    }
}

如果我在持久化之前尝试转储$ job，我会得到结果

对象（AppBundle \ Entity \ Job）＃242（5）{
  [＆＃34; ID＆＃34;：＆＃34;的appbundle \实体\作业＆＃34;：私人] =＆GT; NULL
  [＆＃34;名称＆＃34;：＆＃34;的appbundle \实体\作业＆＃34;：私人] =＆GT; string（3）＆＃34; PHP＆＃34;
  [＆＃34;描述＆＃34;：＆＃34;的appbundle \实体\作业＆＃34;：私人] =＆GT;串（11）   ＆＃34;说明＆＃34; [＆＃34;类别＆＃34;：＆＃34;的appbundle \实体\作业＆＃34;：私人] =＆GT;
  字符串（2）＆＃34; IT＆＃34; [＆＃34;位置＆＃34;：＆＃34;的appbundle \实体\作业＆＃34;：私人] =＆GT;
  字符串（6）＆＃34;伦敦＆＃34;工作

一方面，它说它无法找到Job类。另一方面，它可以很好地创建对象。

任何人都知道它发生了什么？

尝试

php bin / console cache：清除 php bin / console cache：warmup

添加工作类

<?php
