Question

我正在使用一个使用wcf和sharp架构的应用程序，我正在尝试创建一个写入数据库的服务。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() { }
}

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" %>

我创建了一个svcutil.exe http://localhost:1905/LogisticsWCF.svc?wsdl的客户端，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.

我认为我缺少一些尖锐架构的配置，因为当我在.svc文件中不使用Factory="SharpArch.Wcf.NHibernate.ServiceHostFactory, SharpArch.Wcf"时，我没有得到异常，但是我无法写任何内容数据库（我得到一个ISession未配置的异常）。

我试图按照Northwind的例子，但它不起作用，我可以丢失什么？

Answer 1

最后我找到了答案，我在ComponentRegistrar中遗漏了以下一行：

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

Answer 2

您没有从服务方法返回任何内容，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需要请求/响应，即它希望从服务方法获得响应。 “void”不算作回应 - 所以只需标记那些不返回IsOneWay=true任何内容的服务方法，你应该没问题。
