关于通过ServiceHostFactory扩展wcf的问题？？？

在学习wcf，由于项目中通过实现ServiceHostFactory发布的wcf接口——项目中使用UnityServiceHostFactory，我想跳过这个组件，于是用了ServiceHostFactory，

创建一个wcf项目，然后删除相关的.svc文件，自定义类WcfServiceFactory：如下

    public class WcfServiceFactory : ServiceHostFactory

    {

        protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)

        {

            ServiceHost host = new ServiceHost(serviceType, baseAddresses);

            foreach (Uri address in baseAddresses)

            {



                //WSHttpBinding b = new WSHttpBinding(SecurityMode.Message);



                BasicHttpBinding b = new BasicHttpBinding();



                b.Name = serviceType.Name;

                host.AddServiceEndpoint(serviceType.GetInterfaces()[0], b, address);

            }

            return host;

        }

定义ICompany接口：

    [ServiceContract]

    public interface ICompany

    {

        [OperationContract]

        IEnumerable<Company> GetAllCompanies();

    }

接口实现类：

    public class CompanyService : ICompany

    {

        public IEnumerable<Company> GetAllCompanies()

        {

            return new List<Company>()

            {

                new Company{ CompanyId = 1, CompanyName ="company 1", Email="company1@126.com"},

                new Company{CompanyId = 2, CompanyName = "company 2", Email="company2@126.com"}

            };

        }

    }

模型类：

    [DataContract]

    public class Company

    {

        [DataMember]

        public int CompanyId { get; set; }



        [DataMember]

        public string CompanyName { get;set;}



        [DataMember]

        public string Email { get;set;}

    }

配置文件：

  <system.serviceModel>

<!--省略部分-->

    <services>

      <!--<service name="WcfService.User">

        <endpoint address="" binding="basicHttpBinding" contract="WcfService.IUser" />

      </service>-->

      <service name="WcfService.CompanyService">

        <endpoint address="http://localhost:5166/Company" binding="basicHttpBinding" contract="WcfService.ICompany" />

      </service>

    </services>



    <serviceHostingEnvironment multipleSiteBindingsEnabled="true">

      <serviceActivations>

        <add factory="WcfService.Services.WcfServiceFactory" service="WcfService.CompanyService" relativeAddress="Company.svc" />

      </serviceActivations>

    </serviceHostingEnvironment>

  </system.serviceModel>

错误信息：
如果在配置中将“system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled”设置为 true，则需要终结点指定相对地址。如果在终结点上指定相对侦听 URI，则该地址可以是绝对地址。若要解决此问题，请为终结点“http://localhost:5166/Company”指定相对 URI。
