WCF MsmqIntegrationBinding—不从队列中挑选消息

本文关键字:挑选 消息 队列 MsmqIntegrationBinding WCF | 更新日期: 2023-09-27 18:18:35

我有一个遗留客户机,它正在向队列(MSMQ)写入消息。我想使用WCF服务从队列中提取XML消息。我参考了微软的一些文档,并尝试了一些其他的例子,但我似乎不能让它工作。服务主机正在启动,但它没有启动我的进程,也没有从队列中挑选消息。最有可能是用户错误,只是不确定是什么。

我可以看到队列中的消息?

代码示例:

   [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();
            }
        }
    }

应用程序配置:

<?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>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MessageServiceBehavior">
          <serviceDebug includeExceptionDetailInFaults="true" />
          <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>

不确定我做错了什么?

WCF MsmqIntegrationBinding—不从队列中挑选消息

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>

上面的服务名不包含命名空间,它应该始终是服务的完全限定名
