我在Rhino Security中遇到了一个关闭但未处理NHibernate会话的问题。看起来Windsor将关闭会话交给AuthorizationService。直到第二次调用下面的方法才会出现此问题。第一个电话工作正常。 Windsor容器配备了瞬态生活方式。
我正在使用Sharp Architecture 2.0 RC。
调用服务/任务由与AuthorizationRepository相同的Windsor容器处理。
对于是什么导致这个问题的任何想法都将不胜感激？
namespace Rhino.Security.Services
{
public class AuthorizationRepository : IAuthorizationRepository
{
//...
public virtual UsersGroup[] GetAssociatedUsersGroupFor(IUser user)
{
ICollection<UsersGroup> usersGroups =
SecurityCriterions.AllGroups(user)
.GetExecutableCriteria(session) //This session is closed and not connected when the line executes
.AddOrder(Order.Asc("Name"))
.SetCacheable(true)
.List<UsersGroup>();
return usersGroups.ToArray(); //This line of code (ICollection...) throws the exception!!!
}
//...
}}
ISession Facility如下所示：
container.AddFacility<FactorySupportFacility>()
.Register(Component.For<ISession>()
.UsingFactoryMethod(() => NHibernateSession.Current)
.LifeStyle.Is(LifestyleType.Transient));
Rhino安全组件注册如下所示：
private static void AddRhinoSecurityComponentsTo(IWindsorContainer container)
{
// For RhinoSecurity
container.Register(
Component.For<IAuthorizationService>()
.ImplementedBy<AuthorizationService>()
.LifeStyle.Is(LifestyleType.Transient),
Component.For<IAuthorizationRepository>()
.ImplementedBy<AuthorizationRepository>()
.LifeStyle.Is(LifestyleType.Transient),
Component.For<IPermissionsBuilderService>()
.ImplementedBy<PermissionsBuilderService>()
.LifeStyle.Is(LifestyleType.Transient),
Component.For<IPermissionsService>()
.ImplementedBy<PermissionsService>()
.LifeStyle.Is(LifestyleType.Transient)
);
}
调用AuthorizationService的方法是以下两种方法之一，具体取决于：
SecurityHelper（1）：
public static bool IsAllowed(string operation)
{
User user = (User)HttpContext.Current.Session["User"];
IAuthorizationService authorizationService = ServiceLocator.Current.GetInstance<IAuthorizationService>();
return authorizationService.IsAllowed(user as User, operation);
}
SecurityTasks（2）：
public UsersGroup[] GetAssociatedUsersGroupFor(IUser user)
{
return authRepository.GetAssociatedUsersGroupFor(user);
}
NHibernate Init如下所示：
NHibernateSession.Init(
this.webSessionStorage,
new[] { Server.MapPath("~/bin/ClinicalTrials.Infrastructure.dll") },
new AutoPersistenceModelGenerator().Generate(),
Server.MapPath("~/NHibernate.config"));
ysod如下所示：

在_layout.cshtml页面和继承.cshtml页面之间的转换中，会话似乎已关闭。这是正常的吗？我错过了某种方法来控制会话关闭的方式和时间，或者Windsor如何处理会话？
上次会话打开调用堆栈：

第一个会话关闭调用堆栈：

Session is now closed!
我仍然遇到这个问题，并没有找到任何新的解决方案。每隔一段时间，会话最终都会在Rhino Security代码中关闭。因此，Rhino抛出System.ObjectDisposedException。
