Problems integrating nServiceBus with StructureMap
- by SimonB
I'm trying to use StructureMap with nServiceBus.
The Project:
Uses a GenericHost Endpoint to send command messages
Configures nServiceBus using the StructMapBuilder.
Uses a simple StructureMap registry config
Uses a start up class TestServer supporting IWantToRunAtStartup
The TestServer class has ctor dependency on a TestManager class
The TestManager class has ctor dependency on IBus
ObjectFactory.WhatDoIHave() shows StructureMap knows how to construct the classes.
When run I get buildup errors. nServiceBus seems to be overwriting the config?
Note that when I add a IBus ctor depenendency to my event handlers without any other config all appears fine.
Error:
Exception when starting endpoint, error has been logged. Reason: Error creating object with name 'nSeviceBusStructureMapTest.TestServer' : Unsatisfied dependency expressed through constructor argument with index 0 of type [nSeviceBusStructureMapTest.ITestManager] : No unique object of type [nSeviceBusStructureMapTest.ITestManager] is defined : Unsatisfied dependency of type [nSeviceBusStructureMapTest.ITestManager]: expected at least 1 matching object to wire the [miningServiceManage] parameter on the constructor of object [nSeviceBusStructureMapTest.TestServer]
Source:
using System;
using System.Diagnostics;
using NServiceBus;
using StructureMap;
using StructureMap.Configuration.DSL;
namespace nSeviceBusStructureMapTest
{
public class TestSmRegistry : Registry
{
public TestSmRegistry()
{
For<ITestManager>().Use<TestManager>();
For<TestServer>().Use<TestServer>();
}
}
public class TestEndPoint : AsA_Server, IConfigureThisEndpoint, IWantCustomLogging
{
public void Init()
{
Configure.With().StructureMapBuilder(ObjectFactory.Container);
ObjectFactory.Configure(c => c.AddRegistry<TestSmRegistry>());
Debug.WriteLine(ObjectFactory.WhatDoIHave());
}
}
public class TestServer : IWantToRunAtStartup
{
public TestServer(ITestManager miningServiceManage)
{
_miningServiceManage = miningServiceManage;
}
private readonly ITestManager _miningServiceManage;
public void Run()
{
_miningServiceManage.Run();
}
public void Stop() { }
}
public interface ITestManager
{
void Run();
}
public class TestManager : ITestManager
{
public TestManager(IBus bus)
{
_bus = bus;
}
private readonly IBus _bus;
public void Run()
{
if (_bus == null) Debug.WriteLine("Error no bus");
// Send messages on bus;
}
}
}
<MsmqTransportConfig InputQueue="test" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" />
<UnicastBusConfig>
<MessageEndpointMappings>
</MessageEndpointMappings>
</UnicastBusConfig>
Any ideas?
