FluentValidation Autofac

Question

我需要能够向我的ValidatorFactory提供IComponentContext来解析FluentValidation验证器。我有点卡住了。

ValidatorFactory

    public class ValidatorFactory : ValidatorFactoryBase
    {
        private readonly IComponentContext context;

        public ValidatorFactory(IComponentContext context)
        {
            this.context = context;
        }

        public override IValidator CreateInstance(Type validatorType)
        {
            return context.Resolve(validatorType) as IValidator;
        }
    }

如何提供上下文并注册ValidatorFactory

FluentValidation.Mvc.FluentValidationModelValidatorProvider.Configure(x => x.ValidatorFactory = new ValidatorFactory());

我想通了。如果让ValidatorFactory生成IComponentContext，Autofac会自动注入它。

ValidatorFactory

    public class ValidatorFactory : ValidatorFactoryBase
    {
        private readonly IComponentContext context;

        public ValidatorFactory(IComponentContext context)
        {
            this.context = context;
        }

        public override IValidator CreateInstance(Type validatorType)
        {
            return context.Resolve(validatorType) as IValidator;
        }
    }

注册ValidatorFactory

FluentValidation.Mvc.FluentValidationModelValidatorProvider.Configure(x => x.ValidatorFactory = new ValidatorFactory());

而不是将其与Autofac紧密耦合，您可以通过直接使用它来使其通常适用于任何DependencyResolver：

public class ModelValidatorFactory : IValidatorFactory
{
  public IValidator GetValidator(Type type)
  {
    if (type == null)
    {
      throw new ArgumentNullException("type");
    }
    return DependencyResolver.Current.GetService(typeof(IValidator<>).MakeGenericType(type)) as IValidator;
  }

  public IValidator<T> GetValidator<T>()
  {
    return DependencyResolver.Current.GetService<IValidator<T>>();
  }
}

然后，您可以将您的验证器注册到任何类型的DependencyResolver作为强类型的IValidator<T>，并且它将始终以解析结束。
