NHibernate3.2+Asp.net MVC3+Extjs 4.0.2项目实践(三):Services中间业务层

　　Services中间业务层是供Controller调用，调用数据访问层方法实现业务操作，包括service接口与实现。

ILocation_CountryService.cs

public interface ILocation_CountryService

```
    {
```

        IList<Location_Country> GetLocation_Countries();

        IList<Location_Country> GetIndistinctCountries(Country_Query_Index country_Query_Index, object o);

        bool CreateLocation_Country(Location_Country location_Country);

        bool UpdateLocation_Country(Location_Country location_Country);

        bool DeleteLocation_Country(Location_Country location_Country);

        Location_Country FindLocation_Country(Country_Query_Index country_Query_Index, object o);

```
    }
```

ILocation_CountryService.cs

public class Location_CountryService : ILocation_CountryService

```
    {
```

        private TESZ.Data.DataAccess.ILocation_CountryRepository _iLocation_CountryRepository;

        public Location_CountryService(TESZ.Data.DataAccess.ILocation_CountryRepository iLocation_CountryRepository)

```
        {
```

            _iLocation_CountryRepository = iLocation_CountryRepository;

```
        }
```

        public IList<TESZ.Data.Model.Location_Country> GetLocation_Countries()

```
        {
```

            return _iLocation_CountryRepository.FindAll();

```
        }
```

        public IList<TESZ.Data.Model.Location_Country> GetIndistinctCountries(Country_Query_Index country_Query_Index, object o)

```
        {
```

            return _iLocation_CountryRepository.FindIndistinct(country_Query_Index, o);

```
        }
```

        public TESZ.Data.Model.Location_Country FindLocation_Country(Country_Query_Index country_Query_Index, object o)

```
        {
```

            return _iLocation_CountryRepository.FindOne(country_Query_Index, o);

```
        }
```

        public bool CreateLocation_Country(TESZ.Data.Model.Location_Country location_Country)

```
        {
```

            return _iLocation_CountryRepository.Create(location_Country);

```
        }
```

        public bool UpdateLocation_Country(TESZ.Data.Model.Location_Country location_Country)

```
        {
```

            return _iLocation_CountryRepository.Update(location_Country);

```
        }
```

        public bool DeleteLocation_Country(TESZ.Data.Model.Location_Country location_Country)

```
        {
```

            return _iLocation_CountryRepository.Delete(location_Country);

```
        }
```
```
    }
```

再来看一下应用程序如何调用中间业务层。在应用程序启动时，需要装载数据访问层和中间业务层的接口与接口实现，具体是通过Bootstrapper启动装载类来实现，看一下Global.asax.cs和Bootstrapper.cs的代码：

　Global.asax.cs

public class MvcApplication : System.Web.HttpApplication

```
    {
```

        public static void RegisterGlobalFilters(GlobalFilterCollection filters)

```
        {
```

            filters.Add(new HandleErrorAttribute());

```
        }
```

        public static void RegisterRoutes(RouteCollection routes)

```
        {
```

            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

```
            routes.MapRoute(
```
```
                "Home", // Route name
```

                "{controller}/{action}/{id}", // URL with parameters

                new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults

```
            );
```
```
        }
```

        protected void Application_Start()

```
        {
```

            AreaRegistration.RegisterAllAreas();

            RegisterGlobalFilters(GlobalFilters.Filters);

            RegisterRoutes(RouteTable.Routes);

```
            Bootstrapper.Init();
```
```
        }
```
```
    }
```

　Bootstrapper.cs

public static partial class Bootstrapper

```
    {
```

        private static IUnityContainer container;

```
        static Bootstrapper()
```
```
        {
```

            container = new UnityContainer();

```
        }
```
```
        public static void Init()
```
```
        {
```
```
            //Location
```

            container.RegisterType<ILocation_CountryRepository, Location_CountryRepository>();

            container.RegisterType<TESZ.Services.ILocation_CountryService, TESZ.Services.Location_CountryService>();

            container.RegisterType<ILocation_StateProvinceRepository, Location_StateProvinceRepository>();

            container.RegisterType<TESZ.Services.ILocation_StateProvinceService, TESZ.Services.Location_StateProvinceService>();

```
            //Common
```

            container.RegisterType<ICommon_DateRepository, Common_DateRepository>();

            container.RegisterType<TESZ.Services.ICommon_DateService, TESZ.Services.Common_DateService>();

```
            //System
```

            container.RegisterType<ISystem_PurviewRepository, System_PurviewRepository>();

            container.RegisterType<TESZ.Services.ISystem_PurviewService, TESZ.Services.System_PurviewService>();

            container.RegisterType<IViewPageActivator, ViewPageActivator>();

            DependencyResolver.SetResolver(new UnityDependencyResolver(container));

```
        }
```
```
    }
```

　UnityDependencyResolver.cs

public class UnityDependencyResolver : IDependencyResolver

```
    {
```

        private IUnityContainer container;

        public UnityDependencyResolver(IUnityContainer container)

```
        {
```

            this.container = container;

```
        }
```

        public object GetService(Type serviceType)

```
        {
```
```
            try
```
```
            {
```

                return container.Resolve(serviceType);

```
            }
```

            catch (ResolutionFailedException)

```
            {
```

                //额外操作，如日志

```
                return null;
```
```
            }
```
```
        }
```

        public IEnumerable<object> GetServices(Type serviceType)

```
        {
```
```
            try
```
```
            {
```

                return container.ResolveAll(serviceType);

```
            }
```

            catch (ResolutionFailedException)

```
            {
```

                //额外操作，如日志

                return Enumerable.Empty<object>();

```
            }
```
```
        }
```
```
    }
```

　ViewPageActivator.cs

public class ViewPageActivator : IViewPageActivator

```
    {
```

        public object Create(ControllerContext controllerContext, Type type)

```
        {
```

            return Activator.CreateInstance(type);

```
        }
```
```
    }
```

这几个启动配置类都置于Conguration文件夹下。
