註冊已存在的URI

Question

我在通用WCF主​​機，其掃描插件文件夾並加載實現一種「IWebService」的所有組件

然後我用Ninject啓動託管WCF服務工作。 所有配置都在App.config中。

當只有一個插件加載時，此功能非常有用。

但是，當我嘗試啓動（）的第二，它拋出一個異常，指出「註冊已存在的URI」

我在App.config所以我得到真正地定義2個完全不同的服務困惑。

這裏是App.config中

<services> 
     <service name="GenericWebService.WebService" behaviorConfiguration="defaultBehavior"> 
     <host> 
      <baseAddresses> 
      <!-- note, choose an available port--> 
      <add baseAddress="http://localhost:8092/GenericWebService/service" /> 

      </baseAddresses> 
     </host> 
     <endpoint address="http://localhost:8092/GenericWebService/service" name="service1" 
        binding="basicHttpBinding" bindingConfiguration="soapBinding" contract="GenericWebService.ICalculator"/> 
     </service> 

     <service name="GenericWebService.WebService2" behaviorConfiguration="defaultBehavior"> 
     <host> 
      <baseAddresses> 
      <!-- note, choose an available port--> 
      <add baseAddress="http://localhost:8093/GenericWebService2/service"/> 
      </baseAddresses> 
     </host> 
     <endpoint address="http://localhost:8093/GenericWebService2/service" name="service2" 
        binding="basicHttpBinding" bindingConfiguration="soapBinding" contract="GenericWebService.ICalculator2" /> 
     </service> 
    </services> 

這裏是我正在加載它們和啓動主機

private static void StartNinjectSelfHostFromPlugin(IEnumerable<IWebService> webServices) 
     { 
      foreach (var webService in webServices) 
      { 
       var ninjectType = (new NinjectServiceSelfHostFactory()).GetType(); 
       var wcfConfiguration = typeof (NinjectWcfConfiguration) 
        .GetMethod("Create", Type.EmptyTypes) 
        .GetGenericMethodDefinition() 
        .MakeGenericMethod(new[] 
        {webService.GetType(),ninjectType }) 
        .Invoke(null, new object[]{}); 
       var x = new NinjectSelfHostBootstrapper(CreateKernel, wcfConfiguration); 
       _selfHostBootstrappers.Add(x); 
       x.Start(); 
      } 
     } 

任何建議，將不勝感激。

Answer 1

重構的巨量之後，我有這個工作，但我不知道這是否是「正確的」。爲了讓它工作，我不得不在我的webservice類中創建一個新的IKernel，並讓它從NinjectModule繼承並在那裏配置綁定。爲什麼我需要多個內核來實現這一點？我應該補充說，如果我不需要Ninject這個工作，通過使用標準的ServiceHost
