结构映射 - 根据注入依赖项的实例的类型，有条件地为接口选择具体类型

Question

我有两个wcf休息服务如下

using StructureMap;

namespace x.services
{
    public class Global : System.Web.HttpApplication
    {
        ObjectFactory.Configure(x =>
            {
                /* How do I configure Structure map to Use 
                   x.services.service1.Validator for constructing 
                   x.services.service1.Service1 Instances and
                   x.services.service2.Validator for constructing 
                   x.services.service2.Service2 Instances ** */
            }
    }
    public interface IValidator
    {
        /*...*/
    }
}
namespace x.services.service1
{
    public class Service1 : IService1
    {
        public Service1(IValidator validator)
        {
            /*...*/
        }
    }
    public class Validator : IValidator
    {
        /*...*/
    }
}
namespace x.services.service2
{
    public class Service2 : IService2
    {
        public Service2(IValidator validator)
        {
            /*....*/
        }
    }
    public class Validator : IValidator
    {
        /*...*/
    }
}

问题也在这里

如何配置Structure map以使用x.services.service1.Validator构建x.services.service1.Service1 Instances和x.services.service2.Validator以构建x.services.service2.Service2实例< /强>

Answer 1

我们可以使用显式映射：

// As precise IService1 mapping as possible
x.For<IService1>() 
   .Use<x.services.service1.Service1>()
    .Ctor<IValidator>("validator")
     .Is<x.services.service1.Validator>();

// IService2 
x.For<IService2>() 
   .Use<x.services.service2.Service2>()
    .Ctor<IValidator>("validator")
     .Is<x.services.service2.Validator>();

编辑：制作一些类型的单身人士

x.For<x.services.service2.Validator>()
  .Singleton()
  .Use<x.services.service2.Validator>();
