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>();

}
