我正在使用带有NserviceBus 5.2的SendOnlyBus 我的设置代码就像

busConfiguration.UsePersistence<NHibernatePersistence,StorageType.Subscriptions>();
                busConfiguration.AssembliesToScan(AssembliesToScan);
                busConfiguration.UseTransport<MsmqTransport>();
                busConfiguration.PurgeOnStartup(false);
                busConfiguration.UseSerialization<XmlSerializer>();
                return Bus.CreateSendOnly(busConfiguration);

和web.config

    <section name="UnicastBusConfig" type="NServiceBus.Config.UnicastBusConfig,       NServiceBus.Core" />
<section name="MsmqTransportConfig" type="NServiceBus.Config.TransportConfig,  NServiceBus.Core" />

<MsmqTransportConfig InputQueue="XXX" ErrorQueue="XXX" NumberOfWorkerThreads="X" MaxRetries="X" />
<UnicastBusConfig>
    <MessageEndpointMappings>
      <add Messages="X" Endpoint="X" />
      </MessageEndpointMappings>
</UnicastBusConfig>

<add name="NServiceBus/Persistence" connectionString="Data Source=XXX;database=XXX;User ID=XX;Password=XXx;" />

<add key="NServiceBus/Persistence/NHibernate/dialect" value="NHibernate.Dialect.MsSql2005Dialect" />
    <add key="NServiceBus/Persistence/NHibernate/connection.provider" value="NHibernate.Connection.DriverConnectionProvider" />
    <add key="NServiceBus/Persistence/NHibernate/connection.driver_class" value="NHibernate.Driver.SqlClientDriver" />

这会在发布消息时导致错误。

  

无法在此端点上发布 - 没有订阅存储   配置“。

如果我使用Memory Persistence,它可以正常工作但不能使用Hibernate DB-Subscription,无法找出遗漏或错误的内容。 感谢任何帮助?。

说明

NServiceBus未配置订阅持久性,因为您已请求仅发送端点。

仅发送端点没有输入队列,这意味着它们无法接收和存储订阅。如果没有订阅者,尝试发布是没有意义的。

无论

  • 保留仅发送总线,但从使用Bus.Publish()切换到Bus.Send()

  • 通过拨打return Bus.Create(busConfiguration)而不是return Bus.CreateSendOnly(busConfiguration)
  • 来使用完整的公交车


代码示例

NServiceBus 5.2.0 NServiceBus.NHibernate 6.1.2 上发布NHibernate事件作为订阅持久性所需的唯一代码如下:

<强> Program.cs的

using System;
using NServiceBus;
using NServiceBus.Features;
using NServiceBus.Persistence;

class Program
{

    static void Main()
    {
        BusConfiguration busConfiguration = new BusConfiguration();
        busConfiguration.DisableFeature<TimeoutManager>();
        busConfiguration.UsePersistence<NHibernatePersistence, StorageType.Subscriptions>();

        using (IStartableBus bus = Bus.Create(busConfiguration))
        {
            bus.Start();
            bus.Publish(new SomeEvent());

            Console.WriteLine("Published an event");
            Console.ReadLine();
        }
    }

    class SomeEvent : IEvent {}
}

<强>的app.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <connectionStrings>
    <add name="NServiceBus/Persistence" connectionString="Data Source=.;database=database;User ID=user;Password=password;"/>
  </connectionStrings>
  <appSettings>
    <add key="NServiceBus/Persistence/NHibernate/dialect" value="NHibernate.Dialect.MsSql2012Dialect" /> 
  </appSettings>
</configuration>
