Asp.net HTTP错误404.0-在IIS服务器上找不到wcf路由

我在我的WCF项目中有以下提到的设置，但当我在IIS服务器中部署它时，当我尝试像这样访问我的站点时，会出现404错误： Global.asax：

public class Global : System.Web.HttpApplication
{

    protected void Application_Start(object sender, EventArgs e)
    {
        RouteTable.Routes.Add(new ServiceRoute("MyService", new AppServiceHostFactory(), typeof(UserService)));
    }

MyService.cs：

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]

public class MyService : IMyService
{

Web.config：

<system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <modules runAllManagedModulesForAllRequests="true">
        <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    </modules>
</system.webServer>

<system.serviceModel>
    <behaviors>
        <serviceBehaviors>
            <behavior name="">
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="false" />
                               </behavior>
        </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true"
                               aspNetCompatibilityEnabled="true"/>
</system.serviceModel>

AppServiceHostFactory传递给

RouteTable.Routes.Add

方法的

AppServiceHostFactory

是什么？它是自定义服务主机吗？是的。公共类AppServiceHostFactory:ServiceHostFactory{AppServiceHostFactory是否具有与WebServiceHostFactory相同/相似的功能
