Question

所以我正在构建发布者，以下是我的配置

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="MsmqTransportConfig" type="NServiceBus.Config.MsmqTransportConfig, NServiceBus.Core" />
<section name="UnicastBusConfig" type="NServiceBus.Config.UnicastBusConfig, NServiceBus.Core" />
<section name="DBSubscriptionStorageConfig" type="NServiceBus.Config.DBSubscriptionStorageConfig, NServiceBus.Core" />
</configSections>


<!-- 1. In order to configure remote endpoints use the format: "queue@machine" 
   2. Input queue must be on the same machine as the process feeding off of it.
   3. Error queue can (and often should) be on a different machine.
   4. The community edition doesn't support more than one worker thread.
-->

<MsmqTransportConfig
InputQueue="HomeOfficePublisherQueue"
ErrorQueue="error"
NumberOfWorkerThreads="1"
MaxRetries="5"
/>

<DBSubscriptionStorageConfig>
<NHibernateProperties>
  <add Key="connection.provider"
       Value="NHibernate.Connection.DriverConnectionProvider"/>
  <add Key="connection.driver_class"
       Value="NHibernate.Driver.SqlClientDriver"/>
  <add Key="connection.connection_string"
       Value="Server=<dbserver>;initial catalog=NServiceBus;Integrated Security=SSPI"/>
  <add Key="dialect"
       Value="NHibernate.Dialect.MsSql2005Dialect"/>
 </NHibernateProperties>
</DBSubscriptionStorageConfig>


<UnicastBusConfig
DistributorControlAddress=""
DistributorDataAddress=""
ForwardReceivedMessagesTo="">
<MessageEndpointMappings>
</MessageEndpointMappings>
</UnicastBusConfig>


</configuration>

这是我的终点

class EndpointConfig : IConfigureThisEndpoint, AsA_Publisher, IWantCustomInitialization
{
    public void Init()
    {
        NServiceBus.Configure.With()
            .Log4Net()
            .DefaultBuilder()
            .XmlSerializer()
            .UnicastBus()
            .ImpersonateSender(false)
            .MsmqTransport()
            .IsTransactional(true)
            .DBSubcriptionStorage();
    }
}

}

我得到以下异常

启动端点时出现异常，已记录错误。原因：创建名称为“NServiceBus.Unicast.UnicastBus”的对象时出错：通过对象属性'SubscriptionStorage'表示的不满意依赖关系：类型为[NServiceBus.Unicast.Subscriptions.ISubscriptionStorage]的2个对象按类型自动装配，应该有只需1即可自动装配对象'NServiceBus.Unicast.UnicastBus'的属性'SubscriptionStorage'。

感谢任何帮助

我遇到了同样的问题，并通过在配置结束时调用.CreateBus（）解决了这个问题：

class EndpointConfig : IConfigureThisEndpoint, AsA_Publisher, IWantCustomInitialization
{
    public void Init()
    {
        NServiceBus.Configure.With()
            .Log4Net()
            .DefaultBuilder()
            .XmlSerializer()
            .UnicastBus()
            .ImpersonateSender(false)
            .MsmqTransport()
            .IsTransactional(true)
            .DBSubcriptionStorage()
            .CreateBus();
    }
}

如果他们的设置符合您的要求，则仅使用角色。尝试删除As_aPublisher，看看是否适合你。在您的情况下，角色和您自己的代码都将注册一个sub.storeage，这就是为您提供异常。

通过对象属性表达的不满意的依赖性
