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>

<binding serializationFormat="Xml" name="DotNetBinding" durable="false" exactlyOnce="false">

</msmqIntegrationBinding>

</system.serviceModel>
</configuration>
不确定我做错了什么?
——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>
上面的服务名不包含命名空间,它应该始终是服务的完全限定名
