Castle Windsor 注册开放泛型 ILogger

Question

我有我的 Simple Injector 注册：

container.RegisterConditional(typeof(ILogManager),
c => typeof(LogManager<>).MakeGenericType(c.Consumer.ImplementationType),
Lifestyle.Singleton,
c => true);

我需要在使用 Castle Windsor 的不同项目中注册相同的 LogManager。

我试过了

container.Register(Component.For(typeof(ILogger))
            .ImplementedBy(typeof(Log4NetLogger<>).MakeGenericType())
            .LifeStyle.Singleton.Start());

无法正常工作。

不幸的是，这在 Castle 中更为复杂。但是您可以使用 SubDependencyResolver 获得相同的结果：

public class LoggerResolver : ISubDependencyResolver
{
    public bool CanResolve(CreationContext context, ISubDependencyResolver contextHandlerResolver, ComponentModel model, DependencyModel dependency)
    {
        return dependency.TargetType == typeof(ILogger);
    }

    public object Resolve(CreationContext context, ISubDependencyResolver contextHandlerResolver, ComponentModel model, DependencyModel dependency)
    {
        var logger = typeof(LogManager<>).MakeGenericType(model.Implementation);
        return Activator.CreateInstance(logger);
    }
}

比加入内核:

Kernel.Resolver.AddSubResolver(new LoggerResolver())

另一种方法是使用 GenericImplementationMatchingStrategy。如果 LogManager 有一些依赖关系，这个也可以工作：

public class OpenGenericAncestorMatchingStrategy : IGenericImplementationMatchingStrategy
{
    public Type[] GetGenericArguments(ComponentModel model, CreationContext context)
    {
        return new[] { context.Handler.ComponentModel.Implementation };
    }
}

并注册：

container.Register(Component.For<ILogger>().ImplementedBy(typeof(LogManager<>), new OpenGenericAncestorMatchingStrategy()));
