依赖注入和项目结构控制台应用程序 [英] Dependency Injection and project structure for Console applications

问题描述

我有4个项目：

核心（iServer中）：

• 系统


• System.Core程序

DependencyResolver：

• 核心


• StructureMap

基础设施（服务）：

• 核心


• 对外依存度

控制台：

• 核心


• DependencyResolver

Requierements：

我想只有在DependencyResolver使用StructureMap。
此外，控制台应用程序不应该知道的基础建设任何事情。

I am trying to use StructureMap only in the DependencyResolver. Furthermore the Console application should not know anything about Infrastucture.

当我不想引用StructureMap在我的控制台应用程序我必须建立一个服务定位。

When I do not want to reference StructureMap on my Console Application I have to build a ServiceLocator.

在DependencyResolver我有一个引导程序，它负责调用StructureMap注册表的东西（注册）

In the DependencyResolver I have a Bootstrapper that is responsible for calling StructureMap registry stuff (Register)

在我的控制台应用程序，我想获得一个实例。为此，我需要引用StructureMap。另一种方式是写StructureMaps解决方法，围绕一个小包装。

In my Console application I want to get an instance. For this I need to reference StructureMap. Another way would be to write a little wrapper around StructureMaps resolving methods.

是否有从StructureMap？

Is there any other better way of decoupling the console from StructureMap?

推荐答案

虽然我明白了一个道理分离IOC寄存器，解决，发布从应用程序的执行情况，我看不出有任何理由IoC容器不应该在控制台应用程序（成分根）和应用程序。FPGA实现另一个程序，而不是

While I see a reason for separating IoC register,resolve,release from the implementation of the application, I don't see any reason why the IoC container shouldn't be in the console application (the composition root) and the application implemention in another assembly instead.

这样的控制台应用程序是很容易的：

That way the console application is very easy:

1. 创建容器


2. 装载容器配置


3. 解析的应用程序


4. 呼叫的应用程序运行并通过沿


5. 控制台参数配置储藏当应用程序退出的run方法

1. Create the container
2. Load the container configuration
3. Resolve the Application
4. Call run on the application and pass the console arguments along
5. dispose the container when the application exits the run method

随着SM看起来大约是这样的：

With SM it look about like this:

public void Main(params string[] args)
{
    using (var container = new Container())
    {
        container.LoadAllConfigurationModules();
        container.AddRegistry<SomeRegistry>();
        container.GetInstance<Application>().Run(args);
    }
}

有关的东西，你不能在启动时创建创建在你的应用程序组装工厂接口：

For things you can't create at startup you create a factory interface in your application assembly:

interface ISomeFactory { ISomeDependency CreateSomeDependency() }

和通过注入容器实现在控制台应用这个接口，并用它来解决该实例。我猜SM实现看起来是这样的：

and implement this interface in the console application by injecting the container and use it to resolve the instance. I guess the SM implementation looks like this:

public class SomeFactory : ISomeFactory
{
    public SomeFactory(IContainer sontainer) { this.container = container; }
    ISomeDependency CreateSomeDependency() { this.container.GetInstance<ISomeDependency>(); }
}

其他IoC容器甚至能够自动实现这些接口工厂后的功能。

Other IoC container even have the functionallity to implement these interface factories automatically.
