AKKA.NET无法识别我的自定义记录器并默认为BusLogger

我正在学习akka.net。我正在尝试创建自定义记录器。我跟着一个 tutorial blog post here .我无法让Akka连接我的定制日志。显然,这条线 var sys = ActorSystem.Create("AkkaCustomLoggingActorSystem"); 读取akka hocon并根据设置配置日志。当我检查 sys 在创建actor系统之后,我可以看到保存的配置字符串,但记录器的类型为 BusLogger 而不是我的自定义记录器。

我查过了 Akka.NET source for the ActorSystemImpl class .在第441行,logger设置为buslogging,在配置中的任何地方都看不到logger设置。

我创建了一个非常简单的akka.net项目,目标是.NET核心2.0,它演示了这个问题。完整的资料来源如下。我这里缺什么?为什么我不能像教程描述的那样连接我的自定义记录器?

程序.cs:

using Akka.Actor;
using Akka.Event;
using System;

namespace AkkaCustomLogging
{
    class Program
    {
        static void Main(string[] args)
        {
            var sys = ActorSystem.Create("AkkaCustomLoggingActorSystem");
            var logger = Logging.GetLogger(sys, sys, null); // Always bus logger
            Console.ReadLine();
        }
    }
}

自定义记录器.cs:

using Akka.Actor;
using Akka.Event;
using System;

namespace AkkaCustomLogging
{
    public class CustomLogger : ReceiveActor
    {
        public CustomLogger()
        {
            Receive<Debug>(e => this.Log(LogLevel.DebugLevel, e.ToString()));
            Receive<Info>(e => this.Log(LogLevel.InfoLevel, e.ToString()));
            Receive<Warning>(e => this.Log(LogLevel.WarningLevel, e.ToString()));
            Receive<Error>(e => this.Log(LogLevel.ErrorLevel, e.ToString()));
            Receive<InitializeLogger>(_ => this.Init(Sender));
        }

        private void Init(IActorRef sender)
        {
            Console.WriteLine("Init");
            sender.Tell(new LoggerInitialized());
        }

        private void Log(LogLevel level, string message)
        {
            Console.WriteLine($"Log {level} {message}");
        }
    }
}
