Question

我正在使用fluentvalidation并使用structuremap为asp.net mvc3中的操作注入验证器。将业务对象注入验证器对象时遇到问题。我收到这样的错误：

{“StructureMap例外代码：202 \ n没有为PluginFamily Suggestion.Biz.BO.ISubjectBO定义的默认实例，Suggestion.Biz，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null”}

如何将SubjectBO注入SubjectValidator？

SubjectValidator：

public class SubjectValidator : AbstractValidator<SUBJECT>
{
    private ISubjectBO _subjectBO;
    public SubjectValidator(ISubjectBO subjectBO)
    {
        _subjectBO = subjectBO;
        Custom(x=>{
            if(!_subjectBO.CanUpdate(x))
            return new ValidationFailure(null, "error msg");
            return null;
        });
    }
}

SuggestionValidationRegistry：

public class SuggestionValidationRegistry : Registry
{
    public SuggestionValidationRegistry()
    {

        For<IValidator<SUBJECT>>().Singleton().Use<SubjectValidator>();
        ValidatorOptions.ResourceProviderType = typeof(ValidationResources);
    }
}

StructureMapValidatorFactory：

public class StructureMapValidatorFactory : ValidatorFactoryBase
{
    public override IValidator CreateInstance(Type validatorType)
    {

        return ObjectFactory.TryGetInstance(validatorType) as IValidator;
    }
}

App_start：

        ObjectFactory.Configure(cfg => cfg.AddRegistry(new SuggestionValidationRegistry()));
        FluentValidationModelValidatorProvider.Configure(provider => provider.ValidatorFactory = new StructureMapValidatorFactory());
        DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;

是的，我在app_start配置 SuggestionBizRegistry：

public class BizRegistry : Registry
{
    public BizRegistry()
    {
        For<IAwardTypeBO>().Use<AwardTypeBO>();
        For<IQuoteBO>().Use<QuoteBO>();
        For<ISubjectBO>().Use<SubjectBO>();
        For<IContestBO>().Use<ContestBO>();
        For<IApplicationBO>().Use<ApplicationBO>();
        For<IScreenBO>().Use<ScreenBO>();
    }
}

App_start：

protected void Application_Start()
    {
        ConfigureStructureMap();

        AreaRegistration.RegisterAllAreas();

        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);

        EFUnitOfWorkFactory.SetObjectContext(() => new SuggestionModel());


        UnitOfWork.UnitOfWorkFactory = new EFUnitOfWorkFactory();


    }

    private static void ConfigureStructureMap()
    {
        IContainer container = new Container(x =>
        {
            x.For<IControllerActivator>().Use<StructureMapControllerActivator>();
            x.AddRegistry(new BizRegistry());                
        });
        DependencyResolver.SetResolver(new StructureMapDependencyResolver(container));
        ObjectFactory.Configure(cfg => cfg.AddRegistry(new SuggestionValidationRegistry()));
        FluentValidationModelValidatorProvider.Configure(provider => provider.ValidatorFactory = new StructureMapValidatorFactory(container));
        DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;
    }

Answer 1

您可以按照this thread中的说明编写自定义验证工厂。

Answer 2

配置ISubjectBO subjectBO注入

时，尚未配置构造函数参数SubjectValidator
