Question

我是学说和交响乐的新手。我使用doctrine ORM创建了一个带有curd操作的小应用程序。我的插入操作正在运行，但我的列表操作会抛出错误为

[学说\共同\持久性\映射\ MappingException]
“Tab”类不存在

我会将代码粘贴到此处： 我的模特档案：/var/www/html/silexapp/app/Tnq/Todo/Model/Tab.php

    <?php
   namespace Tnq\Todo\Model;
  // app/Tnq/Todo/Model/Tab.php
  /**
  * @Entity(repositoryClass="Repository_TabRepository")    
  @Table(name="tab")
  */
  class Tab
 {
/** @TAB_ID 
 * @Id @Column(type="integer") @GeneratedValue
 * @var int
 */
protected $id;
/**
 * @Column(type="string")
 * @var string
 */
protected $description;
/**
 * @Column(type="string")
 * @var string
 */
protected $tabname;

public function getId()
{
    return $this->id;
}

public function getDescription()
{
    return $this->description;
}

public function setDescription($description)
{
    $this->description = $description;
}

public function setTabname($tabname)
{
    $this->tabname = $tabname;
}

public function getTabname()
{
    return $this->tabname;
}

}

我的Doctrine ORM文件，我在做curd操作：的 /var/www/html/silexapp/app/Tnq/Todo/Command/Tabcommand.php

    <?php
    namespace Tnq\Todo\Command;

  require_once "../vendor/autoload.php";

我的composer.josn文件：

    {
"require": {
    "silex/silex": "~2.0",
    "symfony/console": "~3.1",
    "doctrine/orm": "v2.5.4"
},
"autoload": {
    "psr-0": {
        "Cli": "app/",
        "Tnq\\Todo\\Command": "app/",
        "Tnq\\Todo\\Service": "app/",
          "Tnq\\Todo\\Model": "app/"
      }
    }

 }

这里我的listall getrepository函数抛出错误。任何人都可以帮我找到问题。

提前致谢。

您需要将命名空间类传递给getRepository方法。尝试：

$tabRepository = $entityManager->getRepository('Tnq\\Todo\\Model\\Tab');

getRepository原则中不存在类
