有没有办法将依赖项注入Azure Service Fabric Actor的构造函数？

它现在全部在github和myget上:https://github.com/s-innovations/S-Innovations.ServiceFabric.Unity
并且与aspnet核心依赖注入集成,没有太多麻烦,请查看readme.md的示例
我是Unity的长期用户,并决定制作所需的核心扩展方法,以便在与actor合作时获得良好的依赖注入体验.
我的program.cs现在看起来像这样:
internal static class Program
{
/// <summary>
/// This is the entry point of the service host process.
/// </summary>
private static void Main()
{
try
{
using (var container = new UnityContainer())
{
container.RegisterType<IMessageProcessorClientFactory, DummyFactory>(new HierarchicalLifetimeManager());
container.RegisterType<IMessageClusterConfigurationStore, test>(new HierarchicalLifetimeManager());
container.WithFabricContainer();
container.WithActor<MessageClusterActor>();
container.WithActor<QueueListenerActor>();
container.WithStatelessFactory<ManagementApiServiceFactory>("ManagementApiServiceType");
container.WithActor<VmssManagerActor>();
ServiceFabricEventSource.Current.ServiceTypeRegistered(Process.GetCurrentProcess().Id, typeof(ManagementApiService).Name);
Thread.Sleep(Timeout.Infinite); // Prevents this host process from terminating to keep the service host process running.
}
}
catch (Exception e)
{
ServiceFabricEventSource.Current.ActorHostInitializationFailed(e.ToString());
throw;
}
}
}
我在actor和服务中的位置可以放在构造函数中的依赖项中.
public class VmssManagerActor : StatefulActor<VmssManagerActor.ActorState>, IVmssManagerActor, IRemindable
{
public const string CheckProvision = "CheckProvision";
/// <summary>
/// Cluster Configuration Store
/// </summary>
protected IMessageClusterConfigurationStore ClusterConfigStore { get; private set; }
public VmssManagerActor(IMessageClusterConfigurationStore clusterProvider)
{
ClusterConfigStore = clusterProvider;
}
如果你觉得这很有用,并希望我把它放入一个nuget包中,那么请回答这个问题.
关于实施的一个注意事项,每个演员都会得到自己的范围.这意味着在实现的'HierarchicalLifetimeManager'中注册的所有依赖项IDisposable将自动在actor中处理OnDeactivationAsync.这是通过使用拦截调用的动态类型动态地代理actor类来完成的OnDeactivationAsync.为此,Actor必须是公共定义的.

我知道这已经过时了但是为了文档的缘故,DI现在可以像你期望的那样在Reliable Actor框架中得到支持.
public class ActorOne : Actor<MyActorState>, IMyActor{
private readonly IDependency _dependency;
public ActorOne(IDependency dependency)
{
_dependency = dependency;
}}
然后使用Service Fabric注册Actor及其依赖关系,如下所示:
using (FabricRuntime fRuntime = FabricRuntime.Create()){
fRuntime.RegisterActor(() => new ActorOne(new MyDependency());
Thread.Sleep(Timeout.Infinite);}

在dotPeek中使用dotPeek进行了一些挖掘(尝试从每次调用的Autofac生命周期范围中解析actor),我认为诀窍是创建自己的StatelessActorServiceFactory实现,以及您自己的扩展方法用它注册演员.虽然工厂类被标记为内部,但它的接口(IStatelessServiceFactory)和它创建的服务类型(StatelessActorServiceInstance)都是公共的.不幸的是,它看起来并不像StatelessActorServiceInstance被设计为可扩展的(我希望这只是一个疏忽).
不幸的是,看起来WcfActorCommunicationProvider也被标记为内部,因此您几乎必须从头开始创建自己的管道:
真的不值得努力,是吗？: - /
这就是我现在放弃的地方.考虑到公共API的相对不成熟,我认为现在不值得尝试自己动手,因为如果这种功能完全出现,他们可能会以一种破坏的方式这样做你自己实施的任何事情
