我有两个工作人员角色设置为 nservicebus 端点（nservicebus 3.2.8），并且两者都使用 AzureDataBus 配置来处理大于为 azure 队列分配的大小的消息。我的雇主不允许在配置中放置凭据，因此使用 IProvideConfiguration 来配置存储凭据。
这似乎可行，但似乎 nservicebus 仍在尝试使用本地开发存储连接初始化数据总线通道，这导致工作角色重新启动多次。最终它会启动并选择正确的配置。
关于我应该如何配置数据总线通道，我做错了什么吗？
以下是辅助角色的事件日志中的异常：
An unhandled exception occurred. Type: System.Exception Process ID: 2420

这会立即导致进程终止：
Application: WaWorkerHost.exe

这是我的端点配置：
internal class EndpointConfig : IConfigureThisEndpoint, AsA_Worker, IWantCustomInitialization
{
#region IWantCustomInitialization Members
public void Init()
{
Configure.With()
.DefaultBuilder()
.AzureConfigurationSource()
.MessageForwardingInCaseOfFault()
.AzureMessageQueue()
.JsonSerializer()
.AzureDataBus()
.AzureSubcriptionStorage()
.UnicastBus()
.DisableTimeoutManager()
.DisableSecondLevelRetries()
.IsTransactional(true)
.IsolationLevel(System.Transactions.IsolationLevel.ReadCommitted)
.PurgeOnStartup(false);
}
}
数据总线配置覆盖：
public class ConfigOverride : IProvideConfiguration<AzureDataBusConfig>
{
AzureDataBusConfig IProvideConfiguration<AzureDataBusConfig>.GetConfiguration()
{
return new AzureDataBusConfig()
{
ConnectionString = "my storage key";
};
}
}
