不调用CreateBehavior()

时间:2013-03-25 08:04:24

标签: c# .net wcf

我已提到Why isn't my custom WCF behavior extension element type being found?;但以下是一个不同的问题

我有一个自定义的BehaviorExtensionElement,如下所示。在运行服务时,它的构造函数被调用。但是它不会调用CreateBehavior()方法。因此我的IEndpointBehavior没有被构造。

该服务正常运行,没有任何例外。

知道为什么不调用CreateBehavior()方法吗?

注意:我正在从Visual Studio 2010运行Web服务应用程序。

配置

  <endpointBehaviors>
    <behavior name="EndpointBehavior">
      <XMessageValidator validateRequest="True" validateReply="true" validateWSE="true">
      </XMessageValidator>
    </behavior>
  </endpointBehaviors>


 //Other config entries

<extensions>
  <behaviorExtensions>
    <add name="XMessageValidator" type="MessageInspectorLibrary.ValidationBehaviorExtensionElement, MessageInspectors, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
  </behaviorExtensions>
</extensions>

BehaviorExtensionElement

public class ValidationBehaviorExtensionElement : BehaviorExtensionElement
{
    public ValidationBehaviorExtensionElement()
    {
        //Constructor
    }

    public override Type BehaviorType 
    { 
        get
        {
            return typeof(MessageValidationBehavior);
        } 
    }

    protected override object CreateBehavior()
    {
        throw new Exception("My CreateBehavior");
        return null;

    }

    [ConfigurationProperty("validateRequest", DefaultValue = false, IsRequired = false)]
    public bool ValidateRequest
    {
        get { return (bool)base["validateRequest"]; }
        set { base["validateRequest"] = value; }
    }

    [ConfigurationProperty("validateReply", DefaultValue = false, IsRequired = false)]
    public bool ValidateReply
    {
        get { return (bool)base["validateReply"]; }
        set { base["validateReply"] = value; }
    }

    [ConfigurationProperty("validateWSE", DefaultValue = false, IsRequired = false)]
    public bool ValidateWSE
    {
        get { return (bool)base["validateWSE"]; }
        set { base["validateWSE"] = value; }
    }

}

IEndpointBehavior

public class MessageValidationBehavior : IEndpointBehavior
{
    XmlSchemaSet schemaSet; 
    bool validateRequest; 
    bool validateReply;
    bool validateWSE;

    public MessageValidationBehavior(XmlSchemaSet schemaSet, bool inspectRequest, bool inspectReply, bool inspectWSE)
    {
        this.schemaSet = schemaSet;
        this.validateReply = inspectReply;
        this.validateRequest = inspectRequest;
        this.validateWSE = inspectWSE;

        throw new Exception("My MessageValidationBehavior");
    }


    #region IEndpointBehavior Members

    public void AddBindingParameters(ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyClientBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.ClientRuntime clientRuntime)
    {
        ValidationMessageInspector inspector = new ValidationMessageInspector(schemaSet, validateRequest, validateReply, validateWSE, true);
        clientRuntime.MessageInspectors.Add(inspector);
    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher)
    {
        ValidationMessageInspector inspector = new ValidationMessageInspector(schemaSet, validateRequest, validateReply, validateWSE, false);
        endpointDispatcher.DispatchRuntime.MessageInspectors.Add(inspector);
    }

    public void Validate(ServiceEndpoint endpoint)
    {
    }

    #endregion
}

我建议您将您封装在behaviors node

 <behaviors>
  ....
  <endpointBehaviors>
    <behavior name="EndpointBehavior">
      <XMessageValidator validateRequest="True" validateReply="true" validateWSE="true">
      </XMessageValidator>
    </behavior>
  </endpointBehaviors>
  ....
 </behaviors>

答案 1 :(得分:1)

注意:正如我在问题中所说,即使没有以下更改,服务也会给出正确的响应消息。此外,ValidationBehaviorExtensionElement类被调用。

<强>解决方案

当我使服务名称正确时调用CreateBehavior() - 即namespace.servicename

我的理解是 - 无论服务名称如何,都会创建BehaviorExtension。但只有在服务名称合适时才会创建EndPointBehavior。如果您对此有一些想法/参考,欢迎提供更多细节。

以下是完整的serviceModel配置

<system.serviceModel>

<services>

  <service
          name="WcfServiceApp001.Service1"

    <endpoint address="" binding="basicHttpBinding"
              behaviorConfiguration="EndpointBehavior"
              contract="WcfServiceApp001.IService1"

  </service>
</services>

    <behavior name="InternalPayrollBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
