使用版本2.0.0.1219
我试图通过NServiceBus和VS2010自我托管订阅者和发布者.程序运行并初始化但我无法获取消息.发布者表现得像是发帖,没有错误,但订阅者什么都没收到.
这是订户配置
<?xml version="1.0"?> <configuration> <configSections> <section name="MsmqTransportConfig" type="NServiceBus.Config.MsmqTransportConfig,NServiceBus.Core"/> <section name="UnicastBusConfig" type="NServiceBus.Config.UnicastBusConfig,NServiceBus.Core"/> </configSections> <!-- in order to configure remote endpoints use the format: "queue@machine" input queue must be on the same machine as the process Feeding off of it. error queue can (and often should) be on a different machine. --> <MsmqTransportConfig InputQueue="loads" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5"/> <UnicastBusConfig> <MessageEndpointMappings> <add Messages="NServiceMessage" Endpoint="loads"/> </MessageEndpointMappings> </UnicastBusConfig> <startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup></configuration>
和发布者配置
<?xml version="1.0"?> <configuration> <configSections> <section name="MsmqTransportConfig" type="NServiceBus.Config.MsmqTransportConfig,NServiceBus.Core"/> </configSections> <MsmqTransportConfig InputQueue="loads" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5"/> <UnicastBusConfig DistributorControlAddress="" DistributorDataAddress="" ForwardReceivedMessagesTo=""> <MessageEndpointMappings> <!-- publishers don't need to set this for their own message types --> <!--<add Messages="Messages" Endpoint="messagebus" />--> </MessageEndpointMappings> </UnicastBusConfig> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> </startup> </configuration>
这是发布商代码:
class Program { private static IBus _serviceBus; static void Main(string[] args) { _serviceBus = Configure.With() .Log4Net() .DefaultBuilder() .XmlSerializer() .MsmqSubscriptionStorage() .MsmqTransport() .UnicastBus() .LoadMessageHandlers() .CreateBus() .Start(); while (true) { Console.WriteLine("Press a key to send data."); Console.ReadKey(); SendMessaage(); } } private static void SendMessaage() { LoadMessage message = GetNextMessage(); _serviceBus.Publish(message); } private static LoadMessage GetNextMessage() { LoadMessage result = new LoadMessage(); result.DeliveryDate = DateTime.Today.AddDays(3).ToShortDateString(); result.DestinationCity = "Boise"; result.DestinationCountry = "USA"; result.DestinationState = "ID"; result.EventId = Guid.NewGuid(); result.Time = DateTime.Now.ToUniversalTime(); result.OriginState = "OR"; result.OriginCity = "Portland"; result.OriginCountry = "USA"; result.EquipmentID = 3; return result; } }
和订户代码
class Program { private static IBus _serviceBus; private static LoadMessageHandler _messageHandler; static void Main(string[] args) { _messageHandler = new LoadMessageHandler(); _serviceBus = Configure .With() .Log4Net() .DefaultBuilder() .BinarySerializer() .MsmqSubscriptionStorage() .MsmqTransport() .UnicastBus() .LoadMessageHandlers() .CreateBus() .Start(); Console.ReadKey(); } }
和消息代码
public class LoadMessageHandler : IHandleMessages<LoadMessage> { public void Handle(LoadMessage message) { Console.WriteLine(String.Format("GUID: {0}",message.EventId)); } }
解决方法
更多问题:
1:必须将msmq传输配置为事务性,以便发布者接受订阅消息.有关配置这些内容的示例,请参见http://blogs.planbsoftware.co.nz/?p=234.
2:Publisher正在使用XmLSerializer,而订阅者正在使用BinarySerializer,这使它们不兼容.
