Question

我正在尝试使用Autofac进行注入：

Unhealthy event: SourceId='System.RA', Property='ReplicaOpenStatus', HealthState='Warning', ConsiderWarningAsError=false.
Replica had multiple failures during open on _Node_0. API call: IStatelessServiceInstance.Open(); Error = Autofac.Core.DependencyResolutionException (-2146233088)
An error occurred during the activation of a particular registration. See the inner exception for details. Registration: Activator = ServiceFabricProxy (DelegateActivator), Services = [MYSERVICE.ServiceFabric.ServiceFabric], Lifetime = Autofac.Core.Lifetime.CurrentScopeLifetime, Sharing = None, Ownership = ExternallyOwned ---> An error occurred during the activation of a particular registration.

这些错误总是令人沮丧，因为它们不会停止Visual Studio！

public ServiceFabric(StatelessServiceContext context, ServiceLoggerFactory serviceLoggerFactory, ServiceConfiguration configuration)
    : base(context)
{
    Argument.IsNotNull(() => context);
    Argument.IsNotNull(() => serviceLoggerFactory);
    Argument.IsNotNull(() => configuration);

    _log = serviceLoggerFactory.EnrichLoggerForStatelessServiceContext(this);
    _log.Information($"Service constructed {GetType().FullName}");
}

我已验证构造函数中的类已注册：

public class NodeAutofacModule : Module
{
    protected override void Load(ContainerBuilder builder)
    {
        var assembly = typeof(GlobalAutofacModule).Assembly;
        var appName = assembly.GetName().Name;
        var appVersion = assembly.InformationalVersion();

        builder.Register<ILogger>(container => LoggingHelper.ConfigureLogging(appName, appVersion))
            .SingleInstance();

        builder.RegisterType<ServiceLoggerFactory>()
            .SingleInstance();

        builder.RegisterType<ServiceConfiguration>()
            .AsSelf()
            .SingleInstance();

        // TODO: Register services here
    }
}

当AutoFac无法解析构造函数时，我发现使用它真的很沮丧。

发生这种情况时，有什么方法可以获取更多信息吗？

我的Service Fabric服务启动时正在创建容器。

在SF错误中剪切stacktrace确实很烦人。但是有一种获取错误的更多详细信息的方法。配置容器后，请尝试以下操作：

import sbt._
import Keys._

object TestExtraShotPlugin extends AutoPlugin {
  override def requires = plugins.JvmPlugin
  override def trigger = allRequirements
  object autoImport {
    val testExtraShot = taskKey[Unit]("test then testQuick only on failure")
  }
  import autoImport._

  override def projectSettings = {
    testExtraShot := (Def.taskDyn {
      val t = (Test / test).result.value
      if (t.toEither.isLeft) (Test / testQuick).toTask("")
      else
        Def.task {
          val s = streams.value
          s.log.info("ok!")
        }
    }).value
  }
}

因此，您将可以访问完整的“例外”信息，并可以指定问题。

即使所有对象都可用，也无法使用AutoFac解决Azure Service Fabric服务
