Symfony实体验证不会报告违规行为

Question

I am trying to add some validation to my entity, using the Symfony validation component, i have added some constraints to my User Entity.

/**
 * @param ClassMetadata $metadata
 */
public static function loadValidatorMetadata(ClassMetadata $metadata)
{
    $metadata->addPropertyConstraint('username', new Assert\NotBlank);
    $metadata->addPropertyConstraint('password', new Assert\NotBlank);
    $metadata->addPropertyConstraint('first_name', new Assert\NotBlank);
    $metadata->addPropertyConstraint('last_name', new Assert\NotBlank);
}

Now i want to test if i get some errors, when violating the constraints, this is done like this.

    $user = new User();
    $user->username = '';
    $user->password = '';

    $validator = Validation::createValidator();

    if (0 < count($validator->validate($user))) {
        throw new \RuntimeException('The given user is invalid');
    }

But the count is zero, which is odd, as all the constraints is clearly violated? Am i missing something here? Well i must be :D.

Might be worth to notice, that my application is not a Symfony application; it's a ordinary php application, i am just using the component.

You need to specify which methods act as mapping methods:

$validator = Validation::createValidatorBuilder()
    ->addMethodMapping('loadValidatorMetadata')
    ->getValidator()
