c# – RunAsync中的Spawning actor抛出“对象’CustomActorService.InternalCustomActorService’未实现接口id’1830616258

我正在遵循Service Fabric spawn actor on startup中的建议,在服务开始时产生几个演员.我有一个自定义的ActorService子类,其中包含以下RunAsync覆盖：

internal sealed class InternalCustomActorService : ActorService
{
  protected async override Task RunAsync(CancellationToken cancellationToken)
  {
    await base.RunAsync(cancellationToken);

    for(int i = 0; i < 10; i++)
    {
      ICustomActor proxy = ActorProxy.Create<ICustomActor>(new ActorId(i));
      await proxy.StartAsync();
    }
  }
...

该类在Program.cs中注册如下：

    ActorRuntime.RegisterActorAsync<CustomActor>(
       (context, actorType) => new InternalCustomActorService(context, actorType, () => new CustomActor())).GetAwaiter().GetResult();

但是,我收到以下异常调用proxy.StartAsync()方法：

我的问题是：我做错了什么？

编辑：我试图添加额外的BootstrapperService无状态服务,并从BootstrapperService.RunAsync中产生演员：

protected override async Task RunAsync(CancellationToken cancellationToken)
{
  await base.RunAsync(cancellationToken);
  await Task.Delay(10000);

  for (int i = 0; i < 10; i++)
  {
    ICustomActor proxy = ActorProxy.Create<ICustomActor>(new ActorId(i));
    await proxy.StartAsync();
  }
}

尽管如此,对proxy.StartAsync()的调用会抛出与上面的InternalCustomActorService.RunAsync中完全相同的异常.

解决方法:

从自定义actor服务中删除以下代码：

     protected override IEnumerable<ServiceReplicaListener> CreateServiceReplicaListeners() 
 { 
   var remotingListener = new ServiceReplicaListener(context => this.CreateServiceRemotingListener(context)); 
   return new ServiceReplicaListener[] { remotingListener }; 
 } 

这是删除基础ActorService正在设置的ActorRemotingListener.如果要添加其他侦听器,请调用基本CreateServiceReplicaListeners方法,获取侦听器,然后添加自定义侦听器.
