asp.net-mvc – 将Castle Windsor与SignalR集成 – 我该如何处理

在评论之后,我不再使用下面的方法,但现在使用GlobalHost.DependencyResolver

所以在Global.asax.cs中我初始化了一些东西

public static void Init(IWindsorContainer container)
{
    var conn = configurationManager.ConnectionStrings["SRSQL"].ConnectionString;
    GlobalHost.DependencyResolver.Register(typeof(IHubActivator),() => new SignalHubActivator(container));
    GlobalHost.DependencyResolver.Register(typeof(ILoggingService),container.Resolve<ILoggingService>);
    //etc or you could just pass your existing container to the resolver
    GlobalHost.DependencyResolver.UseSqlServer(conn);    
}

然后在中心

private ILoggingService LoggingService{ get; set; }

    public NotificationHub()
    {
        LoggingService = GlobalHost.DependencyResolver.Resolve<ILoggingService>();
    }

并且为了完整性

public class SignalHubActivator: IHubActivator
{
    private readonly IWindsorContainer _container;

    public SignalHubActivator(IWindsorContainer container)
    {
        _container = container;
    }


    public IHub Create(HubDescriptor descriptor)
    {
                var result=  _container.Resolve(descriptor.HubType) as IHub;

        if (result is Hub)
        {
            _container.Release(result);
        }

    return result;
    }

}

从2012年开始回答老问题

我选择了第一个设置我们自己的DependencyResolver的方法

AspNetHost.SetResolver(new SignalResolver(_container));

如果需要,我可以提供SignalResolver,但暂时不考虑可读性.

另一个重要的注意事项是集线器必须有一个空的构造函数,所以我们的城堡容器通过属性注入,例如

public class NotificationHub : Hub,INotificationHub
    { 

public INotificationService NotificationService { get; set; }

和解析器要求

public class SignalResolver : DefaultDependencyResolver
    {
        private readonly IWindsorContainer _container;

        public SignalResolver(IWindsorContainer container) 
        {
            if (container == null)
            {
                throw new ArgumentNullException("container");
            }
            _container = container;
        }

        public override object GetService(Type serviceType) 
        {
            return TryGet(serviceType) ?? base.GetService(serviceType);
        }

        public override IEnumerable<object> GetServices(Type serviceType)
        {
            return TryGetAll(serviceType).Concat(base.GetServices(serviceType));
        }

        private object TryGet(Type serviceType)
        {
            try
            {
                return _container.Resolve(serviceType);
            }
            catch (Exception)
            {
                return null;
            }
        }

        private IEnumerable<object> TryGetAll(Type serviceType)
        {
            try
            {
                var array = _container.ResolveAll(serviceType);
                return array.Cast<object>().ToList();
            }
            catch (Exception)
            {
                return null;
            }
        }
    }
