StructureMap是一款很老的IoC/DI容器,从2004年.NET 1.1支持至今。
一个使用例子
//创建业务接口
public interface IDispatchService { }
public interface ICourier { }
public interface IPaymentGateway { }
public interface IPaymentMerchant { }
//接口的实现
public class DispacthService : IDispatchService
{
private ICourier _courier;
public DispacthService(ICourier courier)
{
_courier = courier;
}
public override string ToString()
{
return _courier.ToString();
}
}
public class FedExCourier : ICourier { }
public class StreamLinePaymentMerchant : IPaymentMerchant { }
public class PaymentGateway : IPaymentGateway
{
private IPaymentMerchant _paymentMerchant;
public PaymentGateway(IPaymentMerchant paymentMerchant)
{
_paymentMerchant = paymentMerchant;
}
public override string ToString()
{
return _paymentMerchant.ToString();
}
}
//业务使用
public class OrderService
{
private IPaymentGateway _paymentGateway;
private IDispatchService _dispacthService;
public OrderService(IPaymentGateway paymentGateway, IDispatchService dispacthService)
{
_paymentGateway = paymentGateway;
_dispacthService = dispacthService;
}
public override string ToString()
{
return string.Format("IPaymentGateway:{0} IDispatchService:{1}", _paymentGateway.ToString(), _dispacthService.ToString());
}
}
//配置依赖关系
public class BootStrapper
{
public static void ConfigureStructureMap()
{
ObjectFactory.Initialize(x => x.AddRegistry<ModelRegistry>());
}
}
public class ModelRegistry : Registry
{
public ModelRegistry()
{
For<IPaymentGateway>().Use<PaymentGateway>();
For<IPaymentMerchant>().Use<StreamLinePaymentMerchant>();
For<IDispatchService>().Use<DispacthService>();
For<ICourier>().Use<FedExCourier>();
}
}
class Program
{
static void Main(string[] args)
{
BootStrapper.ConfigureStructureMap();//启用配置
OrderService orderService = ObjectFactory.GetInstance<OrderService>();
Console.WriteLine(orderService.ToString());
IPaymentGateway paymentGateway= ObjectFactory.GetInstance<PaymentGateway>();
Console.WriteLine(paymentGateway);
Console.ReadKey();
}
}
