将 WCF 与 Sharp 架构集成的问题

Question

我正在使用一个使用 wcf 和清晰架构的应用程序，我正在尝试创建一个服务来写入数据库。这是我的服务：

[ServiceContract]
public interface IFacilitiesWcfService : ICloseableAndAbortable
{
    [OperationContract]
    void AddFacility(string facility);

}

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
class FacilitiesWcfService:IFacilitiesWcfService
{
    public FacilitiesWcfService(IRepositoryWithTypedId<Facility,string> facilityRepository)
    {
        Check.Require(facilityRepository != null, "facilityRepository may not be null");

        this.facilityRepository = facilityRepository;
    }
    private readonly IRepositoryWithTypedId<Facility,string> facilityRepository;

    public void AddFacility(string facility)
    {
        facilityRepository.DbContext.BeginTransaction();

        Facility newFacility = new Facility();
        newFacility.SetAssignedIdTo(facility);
        newFacility.NAME=facility;
        newFacility.ADDRESS = facility;

        facilityRepository.DbContext.CommitTransaction();
    }
    public void Abort() { }

    public void Close() { }
}

以及 web 项目中的 LogisticsWCF.svc 文件：

<%@ ServiceHost Language="C#" Debug="true" Service="Project.Wcf.FacilitiesWcfService"
 Factory="SharpArch.Wcf.NHibernate.ServiceHostFactory, SharpArch.Wcf" %>

我用svcutil.exe http://localhost:1905/LogisticsWCF.svc?wsdl 创建了一个客户端，然后创建了这个测试用例：

[TestFixture]
class WCFLogisticsTests
{
    [Test]
    public void CanAddFacility()
    {

        FacilitiesWcfServiceClient facility = new FacilitiesWcfServiceClient();
        facility.AddFacility("NEW");
        facility.Close();
    }
}

但我得到了这个例外：

TestCase 'Tests.Project.Web.WCFLogisticsTests.CanAddFacility'
failed: System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail] : The needed dependency of type FacilitiesWcfService could not be located with the ServiceLocator. You'll need to register it with the Common Service Locator (CSL) via your IoC's CSL adapter.

我认为我缺少一些清晰架构的配置，因为当我不在 .svc 文件中使用 Factory="SharpArch.Wcf.NHibernate.ServiceHostFactory, SharpArch.Wcf" 时，我没有得到异常，但我无法向数据库写入任何内容（我得到一个 ISession 未配置异常）。

我尝试遵循 Northwind 示例，但它不起作用，我会遗漏什么？

Answer 1

我终于找到了答案，我在 ComponentRegistrar 中遗漏了以下行：

container.AddComponent("facilityWcfService", typeof(FacilitiesWcfService));

Answer 2

您的服务方法没有返回任何内容，因此需要将其标记为 IsOneWay=true：

[ServiceContract]
public interface IFacilitiesWcfService : ICloseableAndAbortable
{
    [OperationContract(IsOneWay=true)]
    void AddFacility(string facility);

}

默认情况下，WCF 期望请求/响应，即它期望从服务方法返回响应。 "void" 不算作响应 - 所以只需用 IsOneWay=true 标记那些不返回任何内容的服务方法就可以了。
