Symfony2的自定义的验证标注不工作

Question

我在src/VNN/PressboxBundle/Component/Validator/CurrentPasswordValidator.php一个自定义的验证：

<?php 
namespace VNN\PressboxBundle\Component\Validator\Constraints; 

use Symfony\Component\Validator\ConstraintValidator, 
    Symfony\Component\Validator\Constraint, 
    Symfony\Component\Security\Core\Encoder\EncoderFactoryInterface, 
    Symfony\Component\Security\Core\SecurityContextInterface, 
    JMS\DiExtraBundle\Annotation\Validator, 
    JMS\DiExtraBundle\Annotation\InjectParams, 
    JMS\DiExtraBundle\Annotation\Inject; 

/** 
* @Validator("user.validator.current_password") 
*/ 
class CurrentPasswordValidator extends ConstraintValidator 
{ 
    // ... 
} 

然后，我有这样的src/VNN/PressboxBundle/Component/Validator/Contraints/CurrentPassword.php：

<?php 
namespace VNN\PressboxBundle\Component\Validator\Constraints; 

use Symfony\Component\Validator\Constraint; 

/** 
* @Annotation 
*/ 
class CurrentPassword extends Constraint 
{ 
    public $message = "Your current password is not valid"; 

    /** 
    * @return string 
    */ 
    public function validatedBy() 
    { 
     return 'user.validator.current_password'; 
    } 
} 

出于某种原因，当我尝试添加注释使用这个验证器，我得到一个错误。这里是我的实体/注释：

<?php 

namespace VNN\PressboxBundle\Entity; 

use Symfony\Component\Security\Core\User\UserInterface; 
use Doctrine\ORM\Mapping as ORM; 
use Doctrine\ORM\Mapping\JoinTable as JoinTable; 
use Doctrine\ORM\Mapping\JoinColumn as JoinColumn; 
use Symfony\Component\Validator\Constraints as Assert; 
use Symfony\Component\Validator\ExecutionContext; 
use Symfony\Component\Validator\Mapping\ClassMetadata; 
use Symfony\Component\Validator\Constraints\NotBlank; 
use Symfony\Component\Validator\Constraints\MaxLength; 
use Symfony\Component\Validator\Constraints\Email; 
use VNN\PressboxBundle\Component\Validator\Constraints\CurrentPassword; 
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity; 

/** 
* VNN\PressboxBundle\Entity\User 
* 
* @ORM\Table(name="user") 
* @ORM\Entity 
*/ 
class User implements UserInterface, \Serializable 
{ 

    /** 
    * @var string $password 
    * @Assert\NotBlank() 
    * @CurrentPassword() 
    * 
    * @ORM\Column(name="password", type="string", length=255) 
    */ 
    private $password; 
} 

我得到的错误是：

AnnotationException：语义错误]注释 “@VNN \ PressboxBundle \分量\验证\约束\ CurrentPassword” 属性VNN \ PressboxBundle \ Entity \ User :: $密码不存在， 或无法自动加载。

我在做什么错？

检查VNN\PressboxBundle\VNNPressboxBundle()在AppKernel.php内核中是否正确注册。

更新：如果是正确注册，并src/注册为与磁带自动加载回退（假设VNN/是src/下），你可能想尝试手动和加载自己的服务，并检查堆栈跟踪，如果/当它失败：

$validator = $container->get('user.validator.current_password'); 
// Pretending this is a unit test: 
// $this->assertInstanceOf('VNN\PressboxBundle\Component\Validator\Constraints\CurrentPasswordValidator', $validator); 

此外，还要确保您清除缓存（如果dev环境未测试）。

附注（但无关你的问题） - 如果你开始添加更多的验证，这将是更有益的使用这个语法：

<?php 

namespace VNN\PressboxBundle\Entity; 

use VNN\PressboxBundle\Component\Validator\Constraints as VNN; 

class User implements UserInterface, \Serializable 
{ 
    /** 
    * @VNN\CurrentPassword 
    */ 
    private $password; 
}
