Hello All
I am new to WebApi and Nhibernate both . We are using Nhibernate in our web
application and I have learnt it from using it there . We use MVC3 . The
Nhibernate Session is opened using the the global.asax . Below is the file
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Web;
using System.Web.Http;
using System.Web.Http.WebHost;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
using System.Web.SessionState;
using Vish.Common.Utils.DateExtensions;
using Vish.Common.RestApi.Config;
using Vish.Common.RestApi.Controllers;
using Vish.Common.RestApi.Filters;
using Vish.Resi.RestApi.Config;
using Vish.Resi.RestApi.Dependency;
using Autofac;
using Autofac.Integration.Mvc;
using Microsoft.Web.Mvc;
namespace Vish.Resi.RestApi
{
// Note: For instructions on enabling IIS6 or IIS7 classic mode,

public class WebApiApplication : System.Web.HttpApplication
{
private static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new LogHandleErrorAttribute());
}
void ConfigureApi(HttpConfiguration config)
{
config.DependencyResolver = new ApiDependencyResolver();
}
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
//Fixed Model binding bug with nullable parameters.
ModelMetadataProviders.Current = new DataAnnotationsModelMetadataProvider();
log4net.Config.XmlConfigurator.Configure();
var builder = new ContainerBuilder();
// TODO: Clean all this Autofac stuff up and refactor into separate config
class/method
builder.RegisterControllers(Assembly.GetExecutingAssembly(),
typeof(ElmahController).Assembly)
.OnActivated(e => ((Controller)e.Instance).TempDataProvider =
e.Context.Resolve<ITempDataProvider>());
builder.RegisterModelBinders(Assembly.GetExecutingAssembly());
builder.RegisterModelBinderProvider();
builder.RegisterModule(new AutofacWebTypesModule());
builder.RegisterType<ResiApiCookieTempDataProvider>().As<ITempDataProvider>();
//builder.RegisterModule(new MembershipModule());
//builder.RegisterModule(new ValidatorModule());
builder.RegisterModule(new ServicesModule());
builder.RegisterModule(new WebNHibernateModule());
//builder.RegisterModule(new WebQuartzModule());
var container = builder.Build();
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
// Install the certificate

AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
//RegisterRoutes(RouteTable.Routes);
var settings = new WebAppSettings();
//TimeProvider.CurrentTimeZone =
TimeZoneInfo.FindSystemTimeZoneById(settings.ApplicationTimeZone);
ConfigureApi(GlobalConfiguration.Configuration);

I have used a dependency resolver as i need to create a parametered
contructor for the controller .
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http.Dependencies;
using Vish.Resi.Data.Services;
using Vish.Resi.Data.Services.Impl;
using Vish.Resi.RestApi.Controllers;
using NHibernate;
namespace Vish.Resi.RestApi.Dependency
{
public class ApiDependencyResolver : IDependencyResolver
{
private readonly ISession _session;
private static ISettings _settings;
private static IDiscountService _discountService;
private static IAuctionService _auctionService;
private static IAuditService _auditService;
public IDependencyScope BeginScope()
{
// This example does not support child scopes, so we simply return 'this'.
return this;
}
public object GetService(Type serviceType)
{
if (serviceType == typeof(RestApiController))
{
return new RestApiController(_session);
}
else
{
return null;
}
}
public IEnumerable<object> GetServices(Type serviceType)
{
return new List<object>();
}
public void Dispose()
{
// When BeginScope returns 'this', the Dispose method must be a no-op.
}
}
}
But when i reach the controller i see the session is empty as below
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Mvc;
using System.Xml;
using Vish.Resi.Data.Services;
using Vish.Resi.Data.Services.Impl;
using NHibernate;
namespace Vish.Resi.RestApi.Controllers
{
public class RestApiController : ApiController
{
private static ISettings _settings;
private static IDiscountService _discountService;
private static IAuctionService _auctionService;
private static IAuditService _auditService;
private readonly ISession _session;
//
// GET: /RestApi/
public RestApiController(ISession session)
{
_session = session;
}
public XmlDocument Get()
{
var productAdminService = new NhProductAdminService(_session, _settings,
_discountService,
_auctionService,
_auditService);
return productAdminService.GetXmlContract(new
Guid("33cb5122-e3e1-4508-8e1d-a2430062e755"));
}}}
Please Advise . I have been in this state for a while now .
