WCF服务重构实录(下)
前两篇写了在IIS7下部署SVC文件引导WCF服务,采用了net.tcp文件,但是实际的开发中,由于项目的架构已经确定,不宜做大的改动,且为了试项目组成员开发方便,我们之前的项目架构是这样的:
主体是WebHost,这是用来托管WCF服务的,放弃了ConsoleHost,那么现在的问题是能不能仅仅通过配置文件来托管服务,不必通过SVC文件的连接呢,MSDN上给出了一个很好的解决方案: http://msdn.microsoft.com/zh-cn/library/ee816902(en-us,VS.100).aspx
主要使用的是一个配置元素<serviceActivations>,MSDN给出的说明是:
一个配置元素,用于添加可定义虚拟服务激活设置(映射到 Windows Communication Foundation (WCF) 服务类型)的设置。使用此配置元素可以在不使用 .svc 文件的情况下激活承载在 WAS/IIS 中的服务。
主要语法是:
< servicehostingenvironment >
< serviceactivations >
< add service = "String" factory = "String" >
</ add ></ serviceactivations >
</ servicehostingenvironment >
那么有了这个好组件,我们就拿来改造现有的服务吧。
首先,之前的服务配置是
< services >
< service name = "WCFLib.Add" behaviorconfiguration = "MyBehavior" >
< endpoint bindingconfiguration = "netTcpBindConfig" contract = "WCFLib.IAdd" binding = "netTcpBinding" address = "" ></ endpoint >
< endpoint contract = "IMetadataExchange" binding = "mexTcpBinding" address = "mex" ></ endpoint >
</ service >
</ services >
我们为这个配置增加服务激活配置
< servicehostingenvironment >
< serviceactivations >
< add service = "WCFLib.Add" relativeaddress = "NewAddService.svc" >
</ add ></ serviceactivations >
</ servicehostingenvironment >
来看一下现在完整的配置
< system.servicemodel >
< bindings >
< nettcpbinding >
< binding name = "netTcpBindConfig" >
< security mode = "None" >
< transport protectionlevel = "EncryptAndSign" clientcredentialtype = "Windows" >
< message clientcredentialtype = "Windows" >
</ message ></ transport ></ security >
</ binding >
</ nettcpbinding >
</ bindings >
< servicehostingenvironment >
< serviceactivations >
< add service = "WCFLib.Add" relativeaddress = "NewAddService.svc" >
</ add ></ serviceactivations >
</ servicehostingenvironment >
< services >
< service name = "WCFLib.Add" behaviorconfiguration = "MyBehavior" >
< endpoint bindingconfiguration = "netTcpBindConfig" contract = "WCFLib.IAdd" binding = "netTcpBinding" address = "" ></ endpoint >
< endpoint contract = "IMetadataExchange" binding = "mexTcpBinding" address = "mex" ></ endpoint >
</ service >
</ services >
< behaviors >
< servicebehaviors >
< behavior name = "MyBehavior" >
< servicethrottling maxconcurrentsessions = "1000" maxconcurrentinstances = "1000" maxconcurrentcalls = "1000" >
< servicemetadata httpgetenabled = "true" >
< servicedebug includeexceptiondetailinfaults = "true" >
< datacontractserializer maxitemsinobjectgraph = "6553600" >
</ datacontractserializer ></ servicedebug ></ servicemetadata ></ servicethrottling ></ behavior >
</ servicebehaviors >
</ behaviors >
</ system.servicemodel >
删除SVC文件后的目录是这样的
那么怎么使用这个没有SVC文件的WCF服务呢,很简单,我们只要认为有这个服务就可以了,删除之前的Client中的引用,我们重新添加引用一下
再运行一下试试看
