Andreas Ohlund有一篇很好的文章here,内容是关于如何使用Structuremap连接NHibernate会话,以便它自动登入NSB事务。
有没有人知道是否可以通过Autofac实现相同的目标?

我被一位同事给了我一个白痴
public class NHibernateMessageModule : IMessageModule
{
/// <summary>
/// Injected SessionManager.
/// </summary>
public ISessionManager SessionManager { get; set; }
public void HandleBeginMessage()
{
//this session need for NServiceBus and for us
ThreadStaticSessionContext.Bind(SessionManager.OpenSession()); //CurrentSessionContext or ThreadStaticSessionContext
}
public void HandleEndMessage()
{
SessionManager.Session.Flush();
}
public void HandleError()
{
}
}
公共接口ISessionManager { ISession Session {get; } ISession OpenSession(); bool IsSessionOpened {get; } void CloseSession(); }
公共类NHibernateSessionManager:ISessionManager { private ISessionFactory _sessionFactory; 私人ISession _session;
public ISession Session
{
get { return _session; }
private set { _session = value; }
}
public SchemaExport SchemaExport { get; set; }
public NHibernateSessionManager(ISessionFactory sessionFactory)
{
_sessionFactory = sessionFactory;
}
public bool IsSessionOpened
{
get { return Session != null && Session.IsOpen; }
}
public ISession OpenSession()
{
if(Session == null)
{
Session = _sessionFactory.OpenSession();
if (SchemaExport != null)
SchemaExport.Execute(true, true, false, Session.Connection, null);
}
return Session;
}
public void CloseSession()
{
if (Session != null && Session.IsOpen)
{
Session.Flush();
Session.Close();
}
Session = null;
}
}

你做的与你提到的articke完全相同,但选择一个Autofac生命周期。如果您希望在其中注入会话的消息处理中涉及其他类,则可以像这样使用InstancePerLifetimeScope
public class EndpointConfig : IConfigureThisEndpoint, AsA_Publisher, IWantCustomInitialization
{
public void Init()
{
var builder = new ContainerBuilder();
builder.Register(s => SessionFactory.CreateSessionFactory()).As<ISessionFactory>().SingleInstance();
builder.Register(x => x.Resolve<ISessionFactory>().OpenSession()).As<ISession>().InstancePerLifetimeScope();
var container = builder.Build();
Configure.With().AutofacBuilder(container);
}
}
您还可以在NSB上下文中注册所需的任何其他依赖项,并且由于使用了子容器,您将确保它被实例化并正确配置。
