Dependency injection 如何通过配置文件进行IServiceLocator构造函数注入？

如何将IServiceLocator注入我的类构造函数

当我试图通过我的配置（如上所述）执行此操作时，我遇到了一个异常，即无法创建RequestHandlersFactory类，因为unity无法找到带有serviceLocator和assemblyName的构造函数

我有两个接口

public interface IPublicService 
{
    [OperationContract]
    [ServiceKnownType("GetKnownTypes", typeof(KnownTypeProvider))]
    Response Handle(Request request);
}

public interface IRequestHandlersFactory
{
    IRequestHandler GetHandler(Type requestType);
    IRequestHandler GetHandler<T>() 
        where T  : Request;
    IRequestHandler<T, TK> GetHandler<T, TK>()
        where T  : Request
        where TK : Response;
}

现在我想创建unity配置文件：

  <unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
<alias alias="IPublicService" type="MyAssembly.IPublicService, MyAssembly"/>
<alias alias="PublicService" type="MyAssembly.PublicService, MyAssembly"/>
<alias alias="IRequestHandlersFactory" type="MyAssembly.IRequestHandlersFactory, MyAssembly"/>
<alias alias="RequestHandlersFactory" type="MyAssembly.RequestHandlersFactory, MyAssembly"/>
<container>
  <register type="IPublicService" mapTo="PublicService">
    <lifetime type="singleton"/>
  </register>
  <register type="IRequestHandlersFactory" mapTo="RequestHandlersFactory">
    <lifetime type="singleton"/>
    <constructor>
      <param name="assemblyName">
        <value value="MyAssemblyWithHandlers" />
      </param>
      <param name="serviceLocator" dependencyName="WcfServiceLocator" dependencyType="Microsoft.Practices.ServiceLocation.IServiceLocator, Microsoft.Practices.ServiceLocation"/>
    </constructor>
  </register>
</container>

我的配置代码：

        var container = new UnityContainer();

        //configure container
        var unitySection = (UnityConfigurationSection)ConfigurationManager.GetSection("unity");
        var serviceLocator = new UnityServiceLocator(container );
        container.RegisterInstance<IServiceLocator>("WcfServiceLocator", serviceLocator, new ContainerControlledLifetimeManager());
        unitySection.Configure(container);

var container=newunitycontainer（）；
//配置容器
var unitySection=（UnityConfigurationSection）ConfigurationManager.GetSection（“unity”）；
var serviceLocator=新的UnityServiceLocator（容器）；
RegisterInstance（“WcfServiceLocator”、serviceLocator、新ContainerControlled LifetimeManager（））；
配置（容器）；

尝试交换配置文件中构造函数参数的顺序，以便它们与类中的实际参数列表对齐。

        var serviceLocator = new UnityServiceLocator(container );
        container.RegisterInstance<IServiceLocator>("WcfServiceLocator", serviceLocator, new ContainerControlledLifetimeManager());
        unitySection.Configure(container);
