我试图将工作 C# 示例移植到F# 的 OOP 版本。
远程参与者(在一个单独的进程上)没有收到消息。
我收到以下错误:
[ERROR][3/23/2017 4:39:10 PM][Thread 0008][[akka://system2/system/endpointManage

这是工作的 C# 版本:
using (var system = ActorSystem.Create("system1", config))
{
var reply = system.ActorOf<ReplyActor>("reply");
//create a remote deployed actor
var remote1 = system.ActorOf(Props.Create(() => new SomeActor()).WithRouter(FromConfig.Instance), "remoteactor1");
var remote2 = system.ActorOf(Props.Create(() => new SomeActor()).WithRouter(FromConfig.Instance), "remoteactor2");
var remote3 = system.ActorOf(Props.Create(() => new SomeActor()).WithRouter(FromConfig.Instance), "remoteactor3");
var hashGroup = system.ActorOf(Props.Empty.WithRouter(new ConsistentHashingGroup(config)));
Task.Delay(500).Wait();
var routee1 = Routee.FromActorRef(remote1);
hashGroup.Tell(new AddRoutee(routee1));
var routee2 = Routee.FromActorRef(remote2);
hashGroup.Tell(new AddRoutee(routee2));
var routee3 = Routee.FromActorRef(remote3);
hashGroup.Tell(new AddRoutee(routee3));
Task.Delay(500).Wait();
for (var i = 0; i < 5; i++)
{
for (var j = 0; j < 7; j++)
{
var message = new SomeMessage(j, $"remote message: {j}");
hashGroup.Tell(message, reply);
}
}
Console.ReadLine();
}
这是使用 OOP 到 F# 的端口:
use system = ActorSystem.Create("system1", config)
let reply = system.ActorOf<ReplyActor>("reply")
let props1 = Props.Create(fun () -> SomeActor() :> obj)
let props2 = Props.Create(fun () -> SomeActor() :> obj)
let props3 = Props.Create(fun () -> SomeActor() :> obj)
let remote1 = system.ActorOf(props1.WithRouter(FromConfig.Instance), "remoteactor1")
let remote2 = system.ActorOf(props2.WithRouter(FromConfig.Instance), "remoteactor2")
let remote3 = system.ActorOf(props3.WithRouter(FromConfig.Instance), "remoteactor3")
let hashGroup = system.ActorOf(Props.Empty.WithRouter(ConsistentHashingGroup(config)))
Task.Delay(500).Wait();
let routee1 = Routee.FromActorRef(remote1);
hashGroup.Tell(new AddRoutee(routee1));
let routee2 = Routee.FromActorRef(remote2);
hashGroup.Tell(new AddRoutee(routee2));
let routee3 = Routee.FromActorRef(remote3);
hashGroup.Tell(new AddRoutee(routee3));
Task.Delay(500).Wait();
for i = 0 to 5 do
for j = 0 to 7 do
let message = new HashMessage(j, sprintf "remote message: %i" j);
hashGroup.Tell(message, reply);
Console.ReadLine() |> ignore
问题:
我想在调用Props.Create方法时将SomeActor向上转换为对象类型吗?
let props1 = Props.Create(fun () -> SomeActor() :> obj)
let props2 = Props.Create(fun () -> SomeActor() :> obj)
let props3 = Props.Create(fun () -> SomeActor() :> obj)
上面的代码是我知道的唯一区别。
唯一的其他区别是 tcp 路径。
C#的TCP:
remote {
dot-netty.tcp {
port = 8090
hostname = localhost
}
F# 的 TCP:
remote {
helios.tcp {
port = 8090
hostname = localhost
}
