在NancyFx应用程序中请求结束后，DB连接未关闭 [英] DB connection is not closed after request ends in a NancyFx application

问题描述

我正在建立一个Nancy网络应用程序，并使用OrmLite进行数据库访问。我注意到每个请求打开一个新的DB连接，并不关闭它。我认为在应用程序容器中注册OrmLiteConnection类会使其应用程序范围，但它看起来像我缺少的东西。

I'm building a Nancy web app, and using OrmLite for DB access. I noticed that every request opens up a new DB connection and doesn't close it. I thought that registering the OrmLiteConnection class in the Application container would make it application-scoped, but it looks like I'm missing something.

这是我的代码（在 ConfigureApplicationContainer ）：

container.Register<OrmLiteConnectionFactory>(new OrmLiteConnectionFactory(connectionString, SqlServerDialect.Provider));
container.Register<OrmLiteConnection>(
            (cContainer, overloads) => (OrmLiteConnection) cContainer.Resolve<OrmLiteConnectionFactory>().Open());

推荐答案

我移动了 OrmLiteConnection 到 ConfigureRequestContainer 。然后我覆盖 RequestStartup 并添加：

I moved registration of OrmLiteConnection to ConfigureRequestContainer. Then I overrode RequestStartup and added:

pipelines.AfterRequest += (ctx) => {
    //close the connection
    container.Resolve<OrmLiteConnection>().Dispose();
};
