Castle.MicroKernel.ComponentNotFoundException与TypedFactoryFacility

Question

在使用ITcpServer时，我在解决TypedFactoryFacility时遇到了一些问题。看起来温莎没有找到一个合适的组件从工厂返回接口。具体到我的情况，接口ITcpServer是非泛型的，而实现它的类都是泛型的。

以下代码在运行时抛出：

未处理的异常: Castle.MicroKernel.ComponentNotFoundException:没有支持服务ConsoleApplication1的组件。service `1位于Castle.MicroKernel.DefaultKernel.Castle.MicroKernel.IKernelInternal.Resolve(Type服务、IDictionary参数、IReleasePolicy策略( Castle.Facilities.TypedFactory.TypedFactoryComponentResolver.Resolve(IKernelInternal内核)、IReleasePolicy范围(在Castle.Facilities.TypedFactory.Internal.TypedFactoryInterceptor.Resolve(IInvocation调用)、(在Castle.Facilities.TypedFactory.Internal.TypedFactoryInterceptor.Intercept(IInvocation调用))( Castle.DynamicProxy.AbstractInvocation.Proceed() )。 在Castle.Proxies.ITcpServerFactoryProxy.CreateT

守则：

class Program
{
    static void Main(string[] args)
    {
        IWindsorContainer container = new WindsorContainer();
        container.Install(new MyWindsorInstaller());

        var f = container.Resolve<ITcpServerFactory>();
        var tcpServer = f.Create("standard", "something");
        tcpServer.Start();
    }
}

 public class MyWindsorInstaller : IWindsorInstaller
{
    public void Install(IWindsorContainer container, IConfigurationStore store)
    {
        container.AddFacility<TypedFactoryFacility>();
        container.Register(
            Component.For<ITcpServer>().ImplementedBy(typeof(LibUvTcpServer<>)),
            Component.For<ITcpServer>().ImplementedBy(typeof(StandardTcpServer<>)),
            Component.For<ITcpServerFactory>().AsFactory(c => c.SelectedWith(new TcpServerComponentSelector()))
            );
    }
}

public class TcpServerComponentSelector : DefaultTypedFactoryComponentSelector
{
    protected override Type GetComponentType(System.Reflection.MethodInfo method, object[] arguments)
    {
        var serverType = (string)arguments.First();
        return serverType == "standard" ? typeof (StandardTcpServer<>) : typeof(LibUvTcpServer<>);
    }
}

public interface ITcpServerFactory
{
    ITcpServer Create<T>(string serverType, T something);
}

public class StandardTcpServer<T> : ITcpServer
{
    public void Start()
    {
        Console.WriteLine("Started...");
    }
}

public class LibUvTcpServer<T> : ITcpServer
{
    private readonly T something;

    public LibUvTcpServer(T something)
    {
        this.something = something;
    }

    public void Start()
    {
        Console.WriteLine("Started...");
    }
}

public interface ITcpServer
{
    void Start();
}

如果能帮助解决这个问题，我们将不胜感激。

Answer 1

更改以下内容：

protected override Type GetComponentType(System.Reflection.MethodInfo method, object[] arguments)
{
    var serverType = (string)arguments.First();
    if (serverType == "standard") 
    {
        return typeof(StandardTcpServer<>).MakeGenericType(arguments[1].GetType());
    }
    else
    {
        return typeof(LibUvTcpServer<>).MakeGenericType(arguments[1].GetType());
    }
}

以及登记：

Component.For<ITcpServer>().Forward(typeof(LibUvTcpServer<>)).ImplementedBy(typeof(LibUvTcpServer<>)),
Component.For<ITcpServer>().Forward(typeof(StandardTcpServer<>)).ImplementedBy(typeof(StandardTcpServer<>)),

或者，如果您只需要通过工厂解决：

Component.For(typeof(LibUvTcpServer<>)),
Component.For(typeof(StandardTcpServer<>)),

祝好运,
