mvc5中使用autofac注册SignalR

 public void Configuration(IAppBuilder app)
 {
       DependencyConfig.RegisterDependencies(app);
 }

 //Register your SignalR hubs.
  builder.RegisterHubs(Assembly.GetExecutingAssembly());

  var container = builder.Build();
  DependencyResolver.SetResolver(new Autofac.Integration.Mvc.AutofacDependencyResolver(container));

  var configuration = new HubConfiguration
  {
      Resolver = new Autofac.Integration.SignalR.AutofacDependencyResolver(container)
  };
  app.MapSignalR(configuration);

        private ILog _log;
        private IHelper _helper;
        private IGJYB _gJYB;
        private IReconciliation _reconciliation;
        public PushHub(IHelper helper, ILog log, IGJYB gJYB, IReconciliation reconciliation)
        {
            _log = log;
            _helper = helper;
            _gJYB = gJYB;
            _reconciliation = reconciliation;
        }
