相关表的Doctrine2缺失值

我有一个问题，在查询的结果中缺少相关表的值。相关表的Doctrine2缺失值

我的查询是：

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

$repo = $em->getRepository("DbBundle:Auto"); 
$auto = $repo->findAll(); 

var_dump($auto);

在vardump的输出领域hName和hCountry的值丢失...... 我预计学说自动加载realted表的值或有我这样做另外加入？

C:\Apache24\htdocs\src\DbBundle\Controller\DefaultController.php:90: 
array (size=3) 
    0 => 
    object(DbBundle\Entity\Auto)[427] 
     private 'aId' => int 7 
     private 'aName' => string 'A5' (length=2) 
     private 'aPs' => int 190 
     private 'aHersteller' => 
     object(Proxies\__CG__\DbBundle\Entity\Hersteller)[442] 
      public '__initializer__' => 
      object(Closure)[435] 
       ... 
      public '__cloner__' => 
      object(Closure)[437] 
       ... 
      public '__isInitialized__' => boolean false 
      private 'hId' (DbBundle\Entity\Hersteller) => int 1 
      private 'hName' (DbBundle\Entity\Hersteller) => null 
      private 'hCountry' (DbBundle\Entity\Hersteller) => null 
    1 => 
    object(DbBundle\Entity\Auto)[441]

     private 'aPs' => int 130 
     private 'aHersteller' => 
     . 
     . 
     .ASO

您需要创建EntityRepository并选择实体自定义方法与加入相关实体：

namespace AppBundle\Repository; 

use Doctrine\ORM\EntityRepository; 

class AutoRepository extends EntityRepository 
{ 
    public function findAll() 
    { 
     return $this->createQueryBuilder('a') 
      ->select('a','h'); 
      ->join('a.aHersteller', 'h'); 
      ->getQuery() 
      ->getResult() 
     ; 
    } 
}
