Question

NServiceBus 5.1，RavenDB持久性，AutoFac容器，log4net，发布时NuGet中的所有最新版本。

EndpointConfig：

            log4net.Config.XmlConfigurator.Configure();
        LogManager.Use<Log4NetFactory>();

        // Raven DataStore for Freight system
        var freightDataStore = new DocumentStore { 
            ConnectionStringName = "RavenDB",
            DefaultDatabase = "ProTeria.Freight"
        };
        freightDataStore.Initialize();
        freightDataStore.Conventions.IdentityPartsSeparator = "-";
        Raven.Client.Indexes.IndexCreation.CreateIndexes(typeof(ProTeria.NET.RavenDB.BringInvoiceIndexes.BringInvoiceIndexBringIdAndStatus).Assembly, freightDataStore);

        // Raven DataStore for NServiceBus
        var nsbDataStore = new DocumentStore
        {
            ConnectionStringName = "NServiceBus.Persistence",
            DefaultDatabase = "Freight.BookingProcessing"
        };
        nsbDataStore.Initialize();

        // Set up and build AutoFac container
        var builder = new ContainerBuilder();
        builder.RegisterInstance<DocumentStore>(freightDataStore).As<IDocumentStore>().SingleInstance();
        builder.Register(c => 
        {
            var reportsService = new ReportsService();
            return reportsService;
        })
            .As<IReportsService>()
            .SingleInstance();
        builder.Register(c =>
        {
            var getCalcShippingTask = new GetCalculatedShippingReportTask(c.Resolve<IReportsService>(), c.Resolve<IBus>(), c.Resolve<IDocumentStore>());
            return getCalcShippingTask;
        });
        var container = builder.Build();

        // Set up NServiceBus
        configuration.UseContainer<AutofacBuilder>(customizations => customizations.ExistingLifetimeScope(container));
        configuration.Conventions()
            .DefiningCommandsAs(t => t.Namespace != null && t.Namespace.EndsWith("Commands"))
            .DefiningEventsAs(t => t.Namespace != null && t.Namespace.EndsWith("Events"))
            .DefiningMessagesAs(t => t.Namespace != null && t.Namespace.EndsWith("Messages"));
        configuration.UsePersistence<RavenDBPersistence>().SetDefaultDocumentStore(nsbDataStore);
    }

使用Bus.Send（）
ACommand开始传奇 2A。处理ACommand，在处理程序内调用RequestTimeout（InvoiceCreationTimeout）
ACommand处理程序似乎恢复正常。
在我的ACommand处理程序代码之后的某个时刻，我在日志中得到了一个FormatException。

我检查了数据库并且没有存储传单，只有TimeoutDatas，f.ex：

Answer 1

我明白了。这是

freightDataStore.Conventions.IdentityPartsSeparator = "-";

愚弄了Raven，因为生成的id可能看起来像InvoiceSaga-cdd0b4ed-d310-41fa-a8dd-a3dc00b3942f。

编辑这可以通过使用DocumentStore.Conventions.IdentityProviders为Guid注册自定义Raven.Client.Converters.ITypeConverter来解决。有关详细信息，请参阅submitted Raven issue和this SO question

但为什么NSB使用freightDataStore而不是nsbDataStore来持久保存这些传奇，我还不知道。我可能误解了如何使用容器中注册的两个不同的IDataStore配置NSB？对此有何指导？

编辑我为此创建了一个单独的问题：How to configure NServiceBus with two RavenDB IDocumentStores?

RavenDB.SagaPersister.Save中的例外情况，“Guid应该包含带有4个破折号的32位数字”。 Raven里的Guid是空的
