[英]WCF MsmqIntegrationBinding - Not picking Messages off of the queue
我有一個舊客戶端正在將消息寫入隊列(MSMQ)。 我想使用WCF服務從隊列中挑選XML消息。 我跟着一些MSFT文檔並在其他示例中探討過,但我似乎無法讓它工作。 服務主機正在啟動,但它不會觸發我的進程並從隊列中挑選消息。 最有可能的用戶錯誤,只是不確定是什么。
我可以在隊列中看到消息嗎?
代碼示例:
[ServiceContract]
[ServiceKnownType(typeof(XElement))]
public interface IMessageProcessor
{
[OperationContract(IsOneWay = true, Action = "*")]
void ProcessMessage(MsmqMessage<XElement> msg);
}
class MessageServiceClient : IMessageProcessor
{
[OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete = true)]
public void ProcessMessage(MsmqMessage<XElement> msg)
{
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required))
{
Console.WriteLine("Processing {0} ", msg.ToString());
scope.Complete();
}
}
static void Main(string[] args)
{
Uri baseAddress = new Uri(ConfigurationManager.AppSettings["baseAddress"]);
// Create a ServiceHost for the CalculatorService type and provide the base address.
using (ServiceHost serviceHost = new ServiceHost(typeof(MessageServiceClient), baseAddress))
{
// Open the ServiceHostBase to create listeners and start listening for messages.
serviceHost.Open();
// The service can now be accessed.
Console.WriteLine("The service is ready.");
Console.WriteLine("The service is running in the following account: {0}");
Console.WriteLine("Press <ENTER> to terminate service.");
Console.WriteLine();
Console.ReadLine();
// Close the ServiceHostBase to shutdown the service.
serviceHost.Close();
}
}
}
App配置:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<!-- use appSetting to configure MSMQ queue name -->
<add key="QueueName" value=".\private$\MyMessageQueue" />
<add key="baseAddress" value="http://localhost:8000/test/message" />
</appSettings>
<system.serviceModel>
<services>
<service name="MessageServiceClient">
<!-- .Net endpoint-->
<endpoint address="msmq.formatname:DIRECT=OS:.\private$\MyMessageQueue"
binding="msmqIntegrationBinding"
bindingConfiguration="DotNetBinding"
contract="WcfServiceClient.IMessageProcessor" />
</service>
</services>

<serviceBehaviors>
<behavior name="MessageServiceBehavior">

<serviceMetadata />
<!--<serviceThrottling maxConcurrentCalls="20" maxConcurrentSessions="20" />-->
<serviceTimeouts />
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<msmqIntegrationBinding>
<binding serializationFormat="ActiveX" name="ActiveXBinding" durable="false" exactlyOnce="false">
<security mode="None" />
</binding>
<binding serializationFormat="Xml" name="DotNetBinding" durable="false" exactlyOnce="false">
<security mode="None" />
</binding>
</msmqIntegrationBinding>
</bindings>
</system.serviceModel>
</configuration>
不確定我做錯了什么?
--S
在您的配置中,以下元素需要如下所示:
<services>
<service name="WcfServiceClient.MessageServiceClient">
<!-- .Net endpoint-->
<endpoint address="msmq.formatname:DIRECT=OS:.\private$\MyMessageQueue"
binding="msmqIntegrationBinding"
bindingConfiguration="DotNetBinding"
contract="WcfServiceClient.IMessageProcessor" />
</service>
</services>
上面的服務名稱不包含命名空間,它應始終是服務的完全限定名稱
