为什么我的自定义 Symfony 验证器没有执行？

Question

我有以下类

要验证的实体：

<?php
//CompanyName\DataBundle\Entity\Intern\Address.php

namespace CompanyName\DataBundle\Entity\Intern;

use CompanyName\DataBundle\Entity\Country;

use Swagger\Annotations\Property;
use Symfony\Component\Serializer\Annotation\Groups;
use Symfony\Component\Validator\Constraints as Assert;
use CompanyName\ConstraintValidatorBundle\ConstraintValidator;
use CompanyName\ConstraintValidatorBundle\Entity\CountryZipCodeAwareInterface;

/**
 * Class Address
 * @package CompanyName\DataBundle\Entity\Intern
 * @ConstraintValidator\ZipCode
 */
class Address implements CountryZipCodeAwareInterface
{
    /**
     * originId for 'API' send to the Addressbridge and stored in the Addresservice
     *
     * 
     * 
     */
    const ORIGIN_ID_FOR_ADDRESS_FROM_API = 2;

    /**
     * @var integer
     */
    private $id;

    /**
     * @var Name
     * @Property(type="string")
     * @Groups({"createOrder", "shoppingCart"})
     * @Assert\NotBlank()
     * @Assert\Valid()
     */
    private $name;

    /**
     * @var string
     * @Groups({"createOrder", "shoppingCart"})
     * @Assert\NotBlank()
     * @Assert\Type("string")
     * @Assert\Length(max = 100, maxMessage = "Street name cannot be longer than {{ limit }} characters")
     */
    private $street;

    /**
     * @var string
     * @Groups({"createOrder", "shoppingCart"})
     * @Assert\NotBlank()
     * @Assert\Type("string")
     * @Assert\Regex("/^\d+$/")
     * @Assert\Length(max = 5, maxMessage = "House number cannot be longer than {{ limit }} characters")
     */
    private $housenumber;

    /**
     * @var string
     * @Groups({"createOrder", "shoppingCart"})
     * @Assert\Type("string")
     * @Assert\Length(max = 25, maxMessage = "Addition cannot be longer than {{ limit }} characters")

    /**
     * @var Country
     * @Property(type="string")
     * @Groups({"createOrder", "shoppingCart"})
     * @Assert\NotBlank()
     * @Assert\Valid()
     */
    private $country;    
}

在我的自定义验证器中使用的约束：

<?php
//CompanyName\DataBundle\Validator\Name.php

namespace CompanyName\DataBundle\Validator;

use Symfony\Component\Validator\Constraint;

/**
 * Class Name
 * @package CompanyName\DataBundle\Validator
 * @Annotation
 */
class Name extends Constraint
{
    public $message = "No Valid Name provided";

    /**
     * {@inheritdoc}
     */
    public function getTargets()
    {
        die("gggggg");
        return self::CLASS_CONSTRAINT;
    }
}

实际验证者：

<?php
//CompanyName\DataBundle\Validator\NameValidator.php

namespace CompanyName\DataBundle\Validator;

use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;

class NameValidator extends ConstraintValidator
{
    /**
     * Checks if the passed value is valid.
     *
     * @param Name name The value that should be validated
     * @param Constraint $constraint The constraint for the validation
     */
    public function validate($name, Constraint $constraint)
    {
        var_dump($name);
        die();

    }
}

Assert\Valid() 无效。它抛出以下错误：

ExceptionListener.php on line 17: Symfony\Component\Validator\Exception\NoSuchMetadataException {#1052
message: "The class or interface "test" does not exist."

以下是有效载荷：

 "invoiceAddress": {
    "name": "test",
    "street": "Dorpsstraat",
    "housenumber": "123",
    "zipcode": "1234AB",
    "city": "Dorp",
    "country": "nl"
  },
  "deliveryAddress": {
    "name": "Naam",
    "street": "Dorpsstraat",
    "housenumber": "123",
    "housenumberAddition": "A",
    "zipcode": "1234AB",
    "city": "Dorp",
    "country": "nl"
  },

Answer 1

您必须使用自定义验证器断言。 @Assert\Valid() 注释应该在你想要验证与你的实体相关的属性时使用（例如，当你有 User to Address 关系并且你想在 User 处对 $address 进行一些自定义验证实体）。

这就是它寻找 class test 进行验证的原因。查看文档 here

Answer 2

您使用了错误的验证器。

首先将适当的命名空间导入到您的 class 定义中：

use CompanyName\DataBundle\Validator as CompanyAsserts;

然后您的属性注释应该如下所示：

/**
* @var Name
* @Property(type="string")
* @Groups({"createOrder", "shoppingCart"})
* @Assert\NotBlank()
* @CompanyAsserts\Name
*/
private $name;

这样你实际上是在使用你的自定义验证器。删除 @Assert\Valid()、that's not the validatior you are looking for.

您还需要更新约束注释：

/**
 * Class Name
 * @package CompanyName\DataBundle\Validator
 * @Annotation
 * @Target({"PROPERTY", "METHOD", "ANNOTATION"})
 */
class Name extends Constraint {
   // your class
}

（注意 @Target 注释）。此外，从 class.

中删除 getTargets() 方法
