Build pubsub with IIS7 Host WCF by msmq multicast and netmsmqintegrationbinding(IIS7 host WCF通过多播实现出版预订)

开发环境：

Win2008 sp2 VS2008 sp1

Add roles:Web Server(IIS7),Application Server(Message Queuing)

Add features : WCF Activation Msmq:multicasting Support

确认：Net.Msmq Listener Adapter Running

因为我是使用IIS7来Host WCF  而且WCF使用多种通道绑定，所以在WCF所在的web application 确定enable了msmq绑定

如图：

 

Publisher 实现

向多播地址发送Message msg

msg.Body = Your Object;

             #region Test Pub-Sub :Send multicase message of rmi
             string multiCastAddress = "224.0.255.1:8123";
20             using (var queue = new MessageQueue(string.Format("FormatName:MULTICAST={0}", multiCastAddress)))
21             {
22                 RelMomInfo RMI = new RelMomInfo();
23                 RMI.GUID = Guid.NewGuid().ToString();
24                 RMI.strMomInfo = "Client Sent.";
25 
                 Message msg = new Message();
27                 msg.Body = RMI;                    
28 
                 queue.Send(msg, "MultiCast Msg");                    
30             }
31             
32             #endregion 
 

 Contract

 定义WCF契约

namespace RelSrvContract
{
    [ServiceContract]
    [ServiceKnownType(typeof(RelMomInfo))]
    public interface ISrvReceiveMomInfoContract
    {
        [OperationContract(IsOneWay = true, Action = "*")]
        void ReceiveMomInfo(MsmqMessage<RelMomInfo> rmi);
    }
}

  

WCF Services

WCF Service 代码：

namespace SrvSubscriber
{
    [AspNetCompatibilityRequirements(RequirementsMode =
                       AspNetCompatibilityRequirementsMode.Allowed)]   
    public class SrvSubscriberOne:ISrvReceiveMomInfoContract
    {
        public void ReceiveMomInfo(MsmqMessage<RelMomInfo> rmi)
        {
            RelMomInfo RMI = (RelMomInfo)rmi.Body;
            RMI.strMomInfo = RMI.strMomInfo + "SrvReceiveOne Got it!";
            RelComm.SendMsgComm sm = new RelComm.SendMsgComm();
            sm.SendRelMsg(RMI);
        }
    }

    [AspNetCompatibilityRequirements(RequirementsMode =
                   AspNetCompatibilityRequirementsMode.Allowed)]
    public class SrvSubscriberTwo : ISrvReceiveMomInfoContract
    {
        public void ReceiveMomInfo(MsmqMessage<RelMomInfo> rmi)
        {
            RelMomInfo RMI = (RelMomInfo)rmi.Body;
            RMI.strMomInfo = RMI.strMomInfo + "SrvReceiveTwo Got it!";
            RelComm.SendMsgComm sm = new RelComm.SendMsgComm();
            sm.SendRelMsg(RMI);
        }
    }
}

IIS7 Host two WCF subscribers

IIS7 Host 两个WCF 订阅

SrvSubcriberOne.svc 和 SrvSubscriberTwo.svc 的代码为：

<%@ ServiceHost Language="C#" Debug="true"  Service="SrvSubscriber.SrvSubscriberTwo" %>

<%@ ServiceHost Language="C#" Debug="true"  Service="SrvSubscriber.SrvSubscriberOne" %>

配置IIS7支持SVC

需要手动添加*.svc扩展名才能打开IIS7对WCF的支持。

打开“开始|所有程序|附件|命令提示符”，输入“cd C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation”，回车。

再输入“ServiceModelReg.exe -i”，回车。

在“Internet 信息服务(IIS)管理器”中打开“处理程序映射”会看到IIS7增加了对*.svc扩展名的映射。

IIS7的Web server需要配置支持Msmq绑定,Host Wcf 订阅服务的Web Application需要配置支持Msmq绑定.如图:

Web server需要配置支持Msmq

Web Application需要配置支持Msmq，在下图画圈的位置增加net.msmq

这两个WCF 订阅服务分别为 SrvSubcriberOne.svc  SrvSubscriberTwo.svc 这两个WCF分别以绑定在不同的msmq上

需要配置WCF绑定的MSMQ，HOST在IIS7上的WCF的配置

配置bindingconfig 安全部分为None

配置Msmq：

Publisher将消息通过多播地址：224.0.255.1:8123发送出去，我们在Application Server中就会看到这个队列，我们在创建两个用于WCF绑定的非Transactional msmq 配置这两个队列的Multi Cast Address为：224.0.255.1:8123。

运行PublisherClient 发送 body为RelMomInfo对象的Message到多播地址，2个订阅WCF就会取到消息并执行。

注意：

编译后了WCF并没有运行到内存中，需要在IE中浏览一下才可以起作用，而且在修改Web.config后也需要重新刷新。
