NHibernate.HibernateeException:没有绑定到当前上下文的会话

既然您使用的是Ninject,我的建议是使用它来注入会话工厂,而不是IHTTP模块。为此,创建Ninject提供程序类,如下所示。请注意,这需要在代码中进行事务管理,我不喜欢在请求期间盲目地保留打开的事务
public class SessionFactoryProvider : Provider<ISessionFactory>
{
protected override ISessionFactory CreateInstance(IContext context)
{
return Fluently.Configure()
.Database(MsSqlConfiguration.MsSql2008.ConnectionString(c => c.FromConnectionStringWithKey("DefaultConnection")))
.Mappings(m => m.AutoMappings.Add(CreateMappings()))
.CurrentSessionContext<WebSessionContext>()
.BuildSessionFactory();
}
}
public class SessionProvider : Provider<ISession>
{
protected override ISession CreateInstance(IContext context)
{
var sessionFactory = context.Kernel.Get<ISessionFactory>();
var session = sessionFactory.OpenSession();
session.FlushMode = FlushMode.Commit;
return session;
}

然后在NinjectWebCommon中:
private static void RegisterServices(IKernel kernel)
{
// session factory instances are singletons
kernel.Bind<ISessionFactory>().ToProvider<SessionFactoryProvider>().InSingletonScope();
// session-per-request
kernel.Bind<ISession>().ToProvider<SessionProvider>().InRequestScope();
