什么是实现使用温莎城堡在ASP.NET MVC多租户技术的最佳做法？ [英] What is the best practice to implement multi tenancy in ASP.NET MVC using Castle Windsor?

问题描述

我有两个不同的实现的服务，我想注入控制器构造，取决于标准（目前的标准是存储在会话一个简单的值）。

I have a service with two different implementations and I would like to inject into the controllers constructor, depends on a criteria (at the moment the criteria is a simple value stored in session).

这是我现在得到...

Here is what I got now...

Service接口：

Service interface:

public interface IService
{
    string GetSampleText();
}

实施1：

public class FirstService : IService
{
    string GetSampleText()
    {
        return "First Service";
    }
}

实施2：

public class SecondService : IService
{
    string GetSampleText()
    {
        return "Second Service";
    }
}

在注册温莎一个安装程序类：

Registration in a Windsor installer class:

container.Register(AllTypes
  .FromAssemblyInDirectory(new AssemblyFilter(HttpRuntime.BinDirectory))
  .BasedOn<IService>()
  .WithService.FromInterface()
  .Configure(c => c.LifeStyle.Transient));

container.Kernel.AddHandlerSelector(new ServiceHandlerSelector());

我已经实现了IHandlerSelector：

I have implemented an IHandlerSelector:

public class ServiceHandlerSelector : IHandlerSelector { ... }

在此IHandlerSelector实现我可以决定哪些处理程序将在每个所选的方法进行选择的方法HasOpinionAbout（依赖于从会话的值）。

In the HasOpinionAbout method of this IHandlerSelector implementation I can decide which handler will be selected in the SelectHandler method (depends on the value from session).

然后构造注入工作正常的控制器：

Then the constructor injection is working fine on the controllers:

public MyController(IService service) { ... }

所以，我得到了一个有效的解决方案，但我不知道这是否是做到这一点的最好办法。

So I got a working solution, but I am not sure if it is the best way to do this.

意见？建议？

非常感谢。

推荐答案

您是在正确的轨道与处理程序上的选择。以下是使用他们的多租户一些好文章，你可以使用它们，以供参考：

You're on the right track with handler selectors. Here are some good articles on using them for multi-tenancy, you can use them for reference:
