FluentValidation Autofac ValidatorFactory

Question

我需要能夠提供IComponentContext到我的ValidatorFactory來解析FluentValidation驗證器。我有點卡住了。

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; 
     } 
    } 

如何提供上下文和註冊ValidatorFactory

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

Answer 1

我想通了這一點。如果您有ValidatorFactory則需要IComponentContext，Autofac自動注入它。

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; 
     } 
    } 

註冊ValidatorFactory

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

不是不放呢夫婦Autofac，則可以直接使用，使人們普遍適用於任何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>>(); 
    } 
} 

然後你可以用你的驗證器註冊任何類型的DependencyResolver作爲強類型IValidator<T>，它將始終最終解決。
