fluentValidation集成到autofac

废话不说直接上代码

// 首先实现ValidatorFactory



   public class DependencyResolverValidatorFactory : ValidatorFactoryBase

    {

        public override IValidator CreateInstance(Type validatorType)

        { 

            return DependencyResolver.Current.GetService(validatorType) as IValidator;

        }

    }

 

//配置FluentValidation 

  public class FluentValidationConfig

    {

        public static void ConfigureContainer()

        {

            var factory = new DependencyResolverValidatorFactory();

            ModelValidatorProviders.Providers

                .Add(new FluentValidationModelValidatorProvider(factory)); 

            DataAnnotationsModelValidatorProvider

                .AddImplicitRequiredAttributeForValueTypes = false;

            ValidatorOptions.ResourceProviderType = typeof(ValidationResources);

            ValidatorOptions.CascadeMode = CascadeMode.StopOnFirstFailure; 

        }

    }

//在autofac中注册继承自AbstractValidator的验证类



           AssemblyScanner

                .FindValidatorsInAssemblyContaining<AddressValidator>()

               .ForEach(x => builder.RegisterType(x.ValidatorType).As(x.InterfaceType).SingleInstance());

               

    //该类所在程序集内的所有继承自AbstractValidator的验证类都会被注册到autofac容器内

    public class AddressValidator : AbstractValidator<Address>

    {

        public AddressValidator ()

        {

            RuleFor(x => x.Name).NotEmpty().WithLocalizedName(()=>"收件人");

            RuleFor(x => x.Email).NotEmpty().EmailAddress();

            RuleFor(x => x.Mobile).NotEmpty().Mobile();

        }

    }

fluentValidation集成到autofac的好处

//如果fluentValidation不使用autofac容器，那么需要在每个asp.net mv action中调用

Address address = new Address();

AddressValidator validator = new AddressValidator(); 

ValidationResult results = validator.Validate(address);



//或者



[Validator(typeof(AddressValidator))]//此行是重点

    public class Address

    {

        public string Name { get; set; }

        public string Mobile { get; set; }

        public string Email { get; set; }

        public string Details { get; set; }

    }

//用了autofac 上面两种都不需要，在action像没有用到fluentvalidation那样直接：

      if (!ModelState.IsValid)

            {

                return View(model);

            }
