如何使用Autofac确保每个请求有一个NHibernate ISession? [英] How do I make sure that there is one NHibernate ISession per request using Autofac?

问题描述

在我的Application_Start方法中使用的Autofac模块中有以下代码:

I have the following code in an Autofac Module that is used in my Application_Start method:

builder.Register(c => new Configuration().Configure().BuildSessionFactory())
    .SingletonScoped();
builder.Register(c => c.Resolve<ISessionFactory>().OpenSession())
    .HttpRequestScoped();

builder.Register<NHibernateSomethingRepository>().As<ISomethingRepository>();

存储库的构造函数采用ISession作为参数.但是，即使我明确要求将其设为HttpRequestScoped，我还是为整个应用程序完成了一个会话.

The constructor for the repository takes an ISession as argument. But I end up with one session for the whole application, even though I explicitly asked for it to be HttpRequestScoped.

我已经配置了ContainerDisposal HTTP模块.

I have configured the ContainerDisposal HTTP module.

根据文档，您必须创建一个嵌套容器，但是我让Autofac自动关联依赖项.

According to the documentation you have to create a nested container, but I'm letting Autofac autowire the dependencies.

我该怎么办?

谢谢！

推荐答案

我发现了问题，所以我将回答我自己的问题.

I found the problem, so I will answer my own question.

我使用默认范围(在Autofac中为单例范围)注册了我的存储库.我应该这样做:

I registered my repository with the default scope, which in Autofac is singleton scope. I should have done this:

builder.Register<NHibernateSomethingRepository>()
    .As<ISomethingRepository>()
    .HttpRequestScoped;
