  • Autofac Exception Summary Autofac异常汇总

    2021-10-20 15:42:51.740 +08:00 [ERR] 
    System.ObjectDisposedException: Instances cannot be resolved and nested lifetimes cannot be created from this LifetimeScope as it (or one of its parent scopes) has already been disposed.
       at Autofac.Core.Lifetime.LifetimeScope.ResolveComponent(ResolveRequest request)
       at Autofac.ResolutionExtensions.TryResolveService(IComponentContext context, Service service, IEnumerable`1 parameters, Object& instance)
       at Autofac.ResolutionExtensions.ResolveService(IComponentContext context, Service service, IEnumerable`1 parameters)
       at Autofac.ResolutionExtensions.Resolve[TService](IComponentContext context, IEnumerable`1 parameters)

    这个是asp.net mvc遇到的情况,可以在Global.asax.cs里面注入的时候,设置

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

    然后在controller里面开启新线程的时候,

     var resolver = (AutofacDependencyResolver)DependencyResolver.Current;
    using (var scope = resolver.ApplicationContainer.BeginLifetimeScope(MatchingScopeLifetimeTags.RequestLifetimeScopeTag))

    {

    var instance = scope.Resolve<ISomeInterface>();

    }
