我有一个从 2.6 升级到 3.2.7 后无法启动的 NServicebus 项目,端点如下所示:
namespace Customer.Project.SchemaImportService
{
public class SchemaImportEndpoint : IConfigureThisEndpoint, AsA_Server, IWantCustomInitialization
{
private IContainer _container;
public void Init()
{
log4net.Config.XmlConfigurator.Configure();
SetupStructureMap();
Configure.With()
.Log4Net()
.StructureMapBuilder(_container)
.DisableTimeoutManager()
.XmlSerializer()
.CreateBus();
}
private void SetupStructureMap()
{
// implementation omitted
}
}
此外,app.config 看起来像这样:
<configuration>
<configSections>
<section name="MsmqTransportConfig" type="NServiceBus.Config.MsmqTransportConfig, NServiceBus.Core" />
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" requirePermission="false" />
<section name="MessageForwardingInCaseOfFaultConfig" type="NServiceBus.Config.MessageForwardingInCaseOfFaultConfig, NServiceBus.Core" />
<section name="Logging" type="NServiceBus.Config.Logging, NServiceBus.Core" />
</configSections>
<MsmqTransportConfig NumberOfWorkerThreads="1" MaxRetries="5" />
<Logging Threshold="DEBUG" />
<log4net debug="true"> <!-- logging details omitted --> </log4net>
<MessageForwardingInCaseOfFaultConfig ErrorQueue="Customer.Project.SchemaImportService.Error" />
当我调试项目时,我启动了 NServicebus.Host.exe 文件,我尝试切换配置文件(生产、集成和 Lite),结果相同。
给出的异常(离开 init 语句后)如下所示:
Message: "Exception when starting endpoint, error has been logged. Reason: Object reference not set to an instance of an object."

我可以提供的最后一点信息(但也许是最重要的一个)是,如果我删除所有消息队列,则不会自动重新创建主队列。
这些私有队列被创建:
customer.project.schemaimportservice.error
customer.project.schemaimportservice.retries
但是
customer.project.schemaimportservice
队列丢失,即使它与我的命名空间匹配(请参阅帖子顶部)。
我究竟做错了什么?我必须在版本 3.2.7 中手动配置消息队列名称吗?
