使用Ninject可以通过这种方式实现这一点吗?我们是否必须回滚到手动定义每个绑定,即
Bind<X>.To<Y>.WhenInjectedInto(?)
Bind.To.whenInjectedTo(?)
理想情况下,我们将使用以下语法:
Bind<X>.To<Y>.WithDecorator<Z>.When(a => a.HasAttribute<DoCheckAttribute>)
Bind.To.WithDecorator.When(a=>a.HasAttribute)
所以Ninject似乎已经有了一个可以解决这个问题的扩展。使用拦截器扩展,可以将属性写入:
[AttributeUsage(AttributeTargets.Class, AllowMultiple = false, Inherited = true)]
public sealed class DoCheckAttribute : InterceptAttribute
{
public override IInterceptor CreateInterceptor(IProxyRequest request)
{
return request.Context.Kernel.Get<DoCheckInterceptor>();
}
}
这意味着绑定变得非常简单:
Kernel.Bind(x =>
x.FromThisAssembly()
.SelectAllClasses()
.InheritedFrom(typeof(ICommandHandler<>))
.BindAllInterfaces());
你喜欢Ninject吗?如果您愿意,我可以向您展示如何使用简单的注入器:使用装饰器。使用简单的喷油器,实际上很容易。
