我刚刚熟悉了 NServiceBus,并且收到了 MessageDeserialization 异常和堆栈跟踪,如下所示。
对于一些环境信息......我正在使用带有队列的天蓝色持久性。我可以看到订阅表以及订阅者的所有端点地址。
我有 3 个 MVC Web API 托管应用程序。发布导致此异常的消息的服务/API 在其 app.config 中配置为订阅自身和其他 2 个 api。其他似乎没有问题的人只有 1 个订阅。第一个订阅它自己的一个事件。另一个订阅来自第 3 个服务/api 的 3 个事件。
我为解决问题而尝试过的事情。我使用约定来定义我的事件,但现在我的事件消息都实现了 IEvent。我还定义了 JsonSerializer。这是我的总线配置设置...
public class NServiceBusEndpointConfig : IConfigureThisEndpoint, AsA_Worker
{
public static IBus bus;
public void Customize(BusConfiguration busConfig)
{
var configuration = ContainerConfig.Container.Resolve<ICredentialDomainConfig>();
busConfig.AzureConfigurationSource();
busConfig.UseTransport<AzureStorageQueueTransport>()
.ConnectionString(configuration.NServiceBusQueueConnectionString);
busConfig.UsePersistence<AzureStoragePersistence>();
busConfig.EndpointName("service1");
busConfig.UseContainer<AutofacBuilder>(c => c.ExistingLifetimeScope(ContainerConfig.Container));
busConfig.UseSerialization<JsonSerializer>();
busConfig.License(configuration.NServiceBusLicenseString);
}
}
}
这是异常和堆栈跟踪详细信息...

这是所要求的消息类......最初消息中有3个不同的“信息”,但试图简化,所以现在只有事件中的权限信息......
public class CredentialPermissionGrantedEvent : IEvent
{
public PermissionInfo Permission { get; set; }
}
public class PermissionInfo
{
public Guid PermissionReference { get; set; }
public DateTime ActivationDate { get; set; }
public Guid CredentialReference { get; set; }
public Guid DeviceReference { get; set; }
public DateTime ExpirationDate { get; set; }
public string Function { get; set; }
public Guid ScheduleReference { get; set; }
public long Timestamp { get; set; }
}
任何帮助将不胜感激
