我正在遵循Service Fabric spawn actor on startup中的建议,以便在服务启动时生成几个 actor。我有一个具有以下 RunAsync 覆盖的自定义 ActorService 子类:
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,我得到以下异常调用proxy.StartAsync()
方法:
FatalExecutionEngineError occurred
HResult=-2146233088
Message=One or more errors occurred.

我的问题是:我做错了什么?
编辑:我试图添加额外BootstrapperService
的无状态服务并从那里产生演员BootstrapperService.RunAsync
:
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();
}
}
然而,调用会proxy.StartAsync()
引发与上述完全相同的异常InternalCustomActorService.RunAsync
。
