我正在使用SimpleInjector 4和FluentValidation7。我AbstractValidator的依赖于我DbContext。

public class Validator : AbstractValidator<LocationModel>
{
    public LocationModelValidator(IReadOnlyRepository repository)
    {
        // Check the database to see if this location is already present
        RuleFor(x => x.LocationId).Must(x => !repository.Location.Any(i => i.LocationId == x)).WithMessage("A Location with this ID already exists.");
    }
}

我的合成根看起来如下：

var container = new Container();
container.Options.DefaultScopedLifestyle = new AsyncScopedLifestyle();

container.Register<IReadOnlyRepository, LocationDbContext>(Lifestyle.Scoped);
container.Register<IValidatorFactory>(() => new ServiceProviderValidatorFactory(GlobalConfiguration.Configuration));
container.Register(typeof(IValidator<>), assemblies, Lifestyle.Scoped);

container.RegisterWebApiControllers(GlobalConfiguration.Configuration);

container.Verify();

GlobalConfiguration.Configuration.DependencyResolver = 
    new SimpleInjectorWebApiDependencyResolver(container);

ValidatorFactory的实现

public class ServiceProviderValidatorFactory : ValidatorFactoryBase
{
    private readonly HttpConfiguration …
