使用ASP.NET MVC的Castle项目每会话生活方式

这可能就是你想要的。

public class PerSessionLifestyleManager : AbstractLifestyleManager
    {
    private readonly string PerSessionObjectID = "PerSessionLifestyleManager_" + Guid.NewGuid().ToString();

    public override object Resolve(CreationContext context)
    {
        if (HttpContext.Current.Session[PerSessionObjectID] == null)
        {
            // Create the actual object
            HttpContext.Current.Session[PerSessionObjectID] = base.Resolve(context);
        }

        return HttpContext.Current.Session[PerSessionObjectID];
    }

    public override void Dispose()
    {
    }
}

然后加上

<component
        id="billingManager"  
        lifestyle="custom"  
        customLifestyleType="Namespace.PerSessionLifestyleManager, Namespace"  
        service="IInterface, Namespace"
        type="Type, Namespace">
</component>

你需要两门课。。。

实施 IHttpModule 处理会话管理。添加 ILifetimeScope 对象,并在会话过期时再次处理它。这对于确保正确发布组件至关重要。到目前为止,这里给出的其他解决方案没有考虑到这一点。

public class PerWebSessionLifestyleModule : IHttpModule
{
    private const string key = "castle.per-web-session-lifestyle-cache";

    public void Init(HttpApplication context)
    {
        var sessionState = ((SessionStateModule)context.Modules["Session"]);
        sessionState.End += SessionEnd;
    }

    private static void SessionEnd(object sender, EventArgs e)
    {
        var app = (HttpApplication)sender;

        var scope = GetScope(app.Context.Session, false);

        if (scope != null)
        {
            scope.Dispose();
        }
    }

    internal static ILifetimeScope GetScope()
    {
        var current = HttpContext.Current;

        if (current == null)
        {
            throw new InvalidOperationException("HttpContext.Current is null. PerWebSessionLifestyle can only be used in ASP.Net");
        }

        return GetScope(current.Session, true);
    }

    internal static ILifetimeScope YieldScope()
    {
        var context = HttpContext.Current;

        if (context == null)
        {
            return null;
        }

        var scope = GetScope(context.Session, true);

        if (scope != null)
        {
            context.Session.Remove(key);
        }

        return scope;
    }

    private static ILifetimeScope GetScope(HttpSessionState session, bool createIfNotPresent)
    {
        var lifetimeScope = (ILifetimeScope)session[key];

        if (lifetimeScope == null && createIfNotPresent)
        {
            lifetimeScope = new DefaultLifetimeScope(new ScopeCache(), null);
            session[key] = lifetimeScope;
            return lifetimeScope;
        }

        return lifetimeScope;
    }

    public void Dispose()
    {
    }
}

您需要的第二个类是 IScopeAccessor . 这用于弥合HttpModule与内置Windsor之间的差距 ScopedLifestyleManager

public class WebSessionScopeAccessor : IScopeAccessor
{
    public void Dispose()
    {
        var scope = PerWebSessionLifestyleModule.YieldScope();
        if (scope != null)
        {
            scope.Dispose();
        }
    }

    public ILifetimeScope GetScope(CreationContext context)
    {
        return PerWebSessionLifestyleModule.GetScope();
    }
}

二 internal static 方法添加到 PerWebSessionLifestyleModule 支持这一点。

就这样,希望注册它。。。

container.Register(Component
    .For<ISometing>()
    .ImplementedBy<Something>()
    .LifestyleScoped<WebSessionScopeAccessor>());

或者,我将此注册打包到扩展方法中。。。

public static class ComponentRegistrationExtensions
{
    public static ComponentRegistration<TService> LifestylePerSession<TService>(this ComponentRegistration<TService> reg)
        where TService : class
    {
        return reg.LifestyleScoped<WebSessionScopeAccessor>();
    }
}

container.Register(Component
    .For<ISometing>()
    .ImplementedBy<Something>()
    .LifestylePerSession());

听起来您的思路是对的,但是您的SearchOptions类需要实现ISearchOptions:

public class SearchOptions : ISearchOptions { ... }

您还需要告诉Windsor您的SearchController是一个组件,因此您可能也希望在web.config中注册它,尽管我更喜欢从代码中注册(见下文)。

要使Windsor获取您的web.config,您应该如下实例化它:

var container = new WindsorContainer(new XmlInterpreter());

要创建SearchController的新实例,只需执行以下操作:

var searchController = container.Resolve<SearchController>();

要使用基于约定的技术注册给定程序集中的所有控制器,可以执行以下操作:

container.Register(AllTypes
    .FromAssemblyContaining<MyController>()
    .BasedOn<IController>()
    .ConfigureFor<IController>(reg => reg.LifeStyle.Transient));

我的经验是 Andy's answer 不起作用,因为 SessionStateModule.End 是 never raised directly :

尽管结束事件是公共的,但您只能通过在Global.asax文件中添加事件处理程序来处理它。之所以实现此限制,是因为HttpApplication实例被重用以提高性能。会话到期时, 仅执行Global.asax文件中指定的Session_oned事件 ,以防止代码调用与当前正在使用的HttpApplication实例关联的结束事件处理程序。

SessionScopeAccessor 类别:

public class SessionScopeAccessor : IScopeAccessor
{
    private const string Key = "castle.per-web-session-lifestyle-cache";

    public void Dispose()
    {
        var context = HttpContext.Current;

        if (context == null || context.Session == null)
            return;

        SessionEnd(context.Session);
    }

    public ILifetimeScope GetScope(CreationContext context)
    {
        var current = HttpContext.Current;

        if (current == null)
        {
            throw new InvalidOperationException("HttpContext.Current is null. PerWebSessionLifestyle can only be used in ASP.Net");
        }

        var lifetimeScope = (ILifetimeScope)current.Session[Key];

        if (lifetimeScope == null)
        {
            lifetimeScope = new DefaultLifetimeScope(new ScopeCache());
            current.Session[Key] = lifetimeScope;
            return lifetimeScope;
        }

        return lifetimeScope;
    }

    // static helper - should be called by Global.asax.cs.Session_End
    public static void SessionEnd(HttpSessionState session)
    {
        var scope = (ILifetimeScope)session[Key];

        if (scope != null)
        {
            scope.Dispose();
            session.Remove(Key);
        }
    }
}

}

给客户打电话是很重要的 SessionEnd global.asax.cs 文件:

void Session_OnEnd(object sender, EventArgs e)
{
    SessionScopeAccessor.SessionEnd(Session);
}

这是处理SessionEnd事件的唯一方法。
