我正在尝试对自定义验证器使用依赖注入,以便能够使用 entityManager。
我遵循了 Symfony Example: Dependency Injection,但我总是收到此错误消息:
FatalErrorException:错误:在 /home/milos/workspace/merrin3/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Validator/ConstraintValidatorFactory.php 第 68 行中找不到类“isdoi”
这是我的课程:
1. IsDOI 类:
<?php
namespace Merrin\MainBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
/**
* @Annotation
*/
class IsDOI extends Constraint
{
public $message_publisher_DOI = 'The Publisher DOI abbreviation does not correspond to the DOI you filled in !';
public $message_journal_DOI = 'No journal found with the DOI you filled in !';
public $journal;
public $doiAbbreviation;
public function validatedBy() {
return "isdoi";
}
public function getTargets()
{
return self::CLASS_CONSTRAINT;
}
}
2. IsDOIValidator 类:
<?php
namespace Merrin\MainBundle\Validator\Constraints;
use Doctrine\ORM\EntityManager;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
class IsDOIValidator extends ConstraintValidator
{
private $entityManager;
public function __construct(EntityManager $entityManager)
{
$this->entityManager = $entityManager;
}
public function validate($value, Constraint $constraint)
{
$em_mdpipub = $this->entityManager('mdpipub');
//Do some tests here...
}
}
3.服务:
merrin.main.validator.isdoi:
class: Merrin\MainBundle\Validator\Constraints\IsDOIValidator
arguments:
entityManager: "@doctrine.orm.entity_manager"
我哪里错了?谢谢您的帮助。
