我在尝试使用 Symfony2.1 项目中的 Doctrine2 从表（通过实体）获取数据时遇到问题。这是我收到错误的控制器：
/**
* Country list
*/
public function countrylistAction()
{
$em = $this->getDoctrine()->getManager();
$countryList = $em->getRepository('ProjectBaseBundle:SYS_TCountry')
->findAll();
$serializer = new Serializer(array(new GetSetMethodNormalizer()),
array('json' => new JsonEncoder()));
return new Response($serializer->serialize($countryList, 'json'));
}
实体：
<?php
namespace Company\Project\BaseBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* @ORM\Entity
* @ORM\Table(name="SYS_TCountry")
*/
class SYS_TCountry
{
/**
* @ORM\Id
* @ORM\Column(type="string", length=3, nullable=false)
* @var string
*/
protected $idcountry;
/**
* @ORM\Column(type="string", length=75, nullable=false)
* @Assert\NotBlank()
* @var string
*/
protected $name;
....
public function getIdcountry() { return $this->idcountry; }
public function getName() { return $this->name; }
public function getA2() { return $this->a2; }
public function getA3() { return $this->a3; }
public function getIdstatus() { return $this->idstatus; }
public function setIdcountry($idcountry) { $this->idcountry = $idcountry; }
public function setName($name) { $this->name = $name; }
public function setA2($a2) { $this->a2 = $a2; }
public function setA3($a3) { $this->a3 = $a3; }
public function setIdstatus($idstatus) { $this->idstatus = $idstatus; }
public function __toString() { return $this->idcountry; }
}
配置.yml：
# Doctrine Configuration
doctrine:
dbal:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: %database_name%
user: %database_user%
password: %database_password%
charset: UTF8
orm:
auto_generate_proxy_classes: %kernel.debug%
auto_mapping: true
这是错误：
Warning: class_parents():
Class Company\Project\BaseBundle\Entity\SYS_TCountry does not exist and could not be loaded in
/var/www/project/src/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/RuntimeReflectionService.php line 40
这很奇怪，因为正如 Doctrine 在控制台中所说，映射已正确完成：我测试它执行php app/console 学说：映射：信息：
[OK] Company\Project\BaseBundle\Entity\SYS_TCountry
如果我在控制台中执行查询一切正常 - > app/console 学说：查询：sql 'SELECT * FROM SYS_TCountry'，返回结果。
我不知道使用Symfony2.1是否必须配置与 2.0 版本不同的东西，但似乎相同，因为映射是 Doctrine 责任。
