我刚刚熟悉NServiceBus,我收到了MessageDeserialization异常和堆栈跟踪,如下所示。
对于某些环境信息......我正在使用队列的azure持久性。我可以看到订阅表以及我的订阅者的所有端点地址。
我有3个MVC Web API托管应用。发布导致此异常的消息的Service / 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。第一个订阅了自己的一个事件。另一个订阅了来自3rd service / api的3个事件。
我为解决这个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);
}
}
}
以下是异常和堆栈跟踪详细信息...

这是请求的消息类... 最初在消息中有3个不同的“信息”,但是试图简化,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; }
}
非常感谢任何帮助

看起来json.net将您的消息反序列化为JObject而不是消息的类型,两个端点是否都知道相同的类型?如果查看邮件正文,是否包含必要的json.net元数据($ type)?
