我在使用 TypedFactoryFacility 时解决 ITcpServer 时遇到一些问题。看来Windsor没有找到合适的组件来从工厂返回该接口(interface)。我的案例的具体情况是,接口(interface) ITcpServer 是非通用的,而实现它的类都是通用的。
以下代码运行时会抛出异常:
Unhandled Exception: Castle.MicroKernel.ComponentNotFoundException: No component for supporting the service ConsoleApplication1.StandardTcpServer`1 was found at Castle.MicroKernel.DefaultKernel.Castle.MicroKernel.IKernelInternal.Resolve(Type service, IDictionary arguments, IReleasePolicy policy) at Castle.Facilities.TypedFactory.TypedFactoryComponentResolver.Resolve(IKernelInternal kernel, IReleasePolicy scope) at Castle.Facilities.TypedFactory.Internal.TypedFactoryInterceptor.Resolve(IInvocation invocation) at Castle.Facilities.TypedFactory.Internal.TypedFactoryInterceptor.Intercept(IInvocation invocation) at Castle.DynamicProxy.AbstractInvocation.Proceed()
at Castle.Proxies.ITcpServerFactoryProxy.Create[T](String serverType, T something)
代码:
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();
}
任何解决问题的帮助都将不胜感激。
最佳答案
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());
}
}
和注册:
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析:
Component.For(typeof(LibUvTcpServer<>)),
Component.For(typeof(StandardTcpServer<>)),
祝你好运
