getRepository 原则中不存在类

我对教义和交响乐都很陌生。我使用 ORM 学说创建了一个带有 curd 操作的小应用程序。我的插入操作正在运行，但我的列表操作抛出一个error as

[学说\通用\持久性\映射\映射异常]
类“Tab”不存在

我将在这里粘贴我的代码：我的模型文件：/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，我在其中进行增删改查操作：/var/www/html/silexapp/app/Tnq/Todo/Command/Tabcommand.php

我的composer.json 文件：

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

        "Tnq\\Todo\\Service": "app/",
          "Tnq\\Todo\\Model": "app/"
      }
    }

 }

这里我的 listall getrepository 函数抛出错误。 谁能帮我找到问题所在。

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');
