仅当注册ILogger位于RegisterAggregateService

内时才会收到错误

[ComponentNotRegisteredException: The requested service 'Autofac.Extras.NLog.ILogger' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.]

builder.RegisterModule<NLogModule>();
builder.RegisterModule(new AutofacWebTypesModule());
builder.RegisterAggregateService<ImportController.IImportControllerDep>();

Answer 1

使用来自Autofac.Extras.NLog的ILogger - 而不是来自NLog

Answer 2

使用flutter: assets: - lib/img_package/example.png从服务定位器解析 https://github.com/ziyasal/Autofac.Extras.NLog#register-simplenlogmodule-to-autofac

SimpleNLogModule

仅使用RegisterAggregateService未注册Autofac.Extras.NLog.ILogger时出错
