c# - Rebus with Simple Injector 重大变更

Question

场景:

• 使用多个卫星库的 Web API 应用程序
• .NET Framework 4.6
• 简单注入(inject)器
• 字谜
• Rebus.AzureServiceBus
• Rebus.SimpleInjector

在我的应用程序中有多个附属库，其中大部分都有一个实现 SimpleInjector IPackage 接口(interface)的类，即将不同库中的容器注册进行分组。这些包在启动时注册

container.RegisterPackages(AppDomain.CurrentDomain.GetAssemblies());

其中一个包包含 Rebus 配置

IContainerAdapter adapter = new SimpleInjectorContainerAdapter( container );
Configure.With( adapter )
            .Transport( t => t.UseAzureServiceBusAsOneWayClient( connectionString, AzureServiceBusMode.Standard ) )
            .Routing( r =>
            r.TypeBased()
                .MapAssemblyOf<TransactionCreated>( "MyQueue" )
            )
            .Options( oc => {
                oc.SetNumberOfWorkers( 1 );
            } )
            .Start();

今天早上我们已经将 Rebus 包升级到以下版本:

• 字谜 4.0.1
• Rebus.AzureServiceBus 4.0.0
• Rebus.SimpleInjector 4.0.0

升级后系统停止工作，现在我们得到以下错误

The container can't be changed after the first call to GetInstance, GetAllInstances and Verify. Please see https://simpleinjector.org/locked to understand why the container is locked. The following stack trace describes the location where the container was locked:

通过调试代码，我们可以看到在注册 rebus 的包之后又注册了另一个包，所以错误的原因。我们可以确认没有对代码进行任何修改，并且它在以前的版本中按预期正常工作。

我还可以确认通过降级到这些版本问题就消失了

• 字谜 3.1.5
• Rebus.AzureServiceBus 3.0.0
• Rebus.SimpleInjector 3.0.0

有什么建议吗？

编辑:根据@Steven 的要求，我添加了完整的堆栈跟踪

很抱歉来晚了对这个问题的 react :)

我终于有时间了解 SimpleInjector 如何进行容器注册，并了解 Rebus 配置 API 如何以某种方式转变为以这种方式工作。

原来是平时的

Configure.With(new MyFavoriteContainerAdapter(container))
    .(...)
    .Start();

咒语必须以某种方式移动到 Func<IBus> 中，这样就可以在实际启动总线之前完成所有与 Rebus 相关的注册(以及您自己的注册)。

结果(刚刚在 NuGet.org 上的 Rebus.SimpleInjector 5.0.0-b01 中出现)是这个 API:

public class RebusPackage : IPackage
{
    public void RegisterServices(Container container)
    {
        Console.WriteLine("Calling RebusPackage");

        container.ConfigureRebus(
            configurer => configurer
                .Transport(t => t.UseInMemoryTransport(new InMemNetwork(), "test"))
                .Start()
        );

    }
}

如果您正在使用 SimpleInjector.Packaging 或简单地使用它，它会是这样的

container.ConfigureRebus(
    configurer => configurer
        .Transport(t => t.UseInMemoryTransport(new InMemNetwork(), "test"))
        .Start()
);

如果你只有一个 SimpleInjector container .

当你认为是时候启动公共(public)汽车时，你要么

container.StartBus();

或者你等到IBus已解决。
