静态初始化设计思路

发布于 2025-01-01 06:31:25 字数 713 浏览 0 评论 0原文

目前，我的 MVC 3 应用程序依赖于在 Application_Start() 中初始化的静态类，如下所示：

protected void Application_Start()
{
    MyDependency.Initialize();
}

静态类看起来或多或少类似于以下内容：

public static class MyDependency
{
    public static void Initialize()
    {
        // Perform some I/O...
    }
}

此依赖项在属性类中使用，该属性类带有警告没有运行时依赖项（因此在 Application_Start() 中调用初始化）

public class MyAttributeClass : ...
{
    public MyAttributeClass()
    {
        MyDependency.DoSomething(); //...
    }
}

最终，我们商店中的其他开发人员将不得不使用这个 API，我想看看是否有办法摆脱这一行在Application_Start()（Global.asax 中的额外代码行可能是一个被遗忘的步骤）

例如，是否有一种方法可以将 MyDependency 类“挂钩”到管道中，而无需编辑 Global.asax？

原文

Currently, my MVC 3 app has a dependency on a static class that is initialized in the Application_Start() like this:

protected void Application_Start()
{
    MyDependency.Initialize();
}

With the static class looking more or less like the following:

public static class MyDependency
{
    public static void Initialize()
    {
        // Perform some I/O...
    }
}

This dependency is used in an attribute class, which comes with the caveat of having no run-time dependencies (hence the call to initialize in the Application_Start())

public class MyAttributeClass : ...
{
    public MyAttributeClass()
    {
        MyDependency.DoSomething(); //...
    }
}

Ultimately, other developers in our shop will have to use this API, and I'd like to see if there's a way to get rid of the line in the Application_Start() (an extra line of code in the Global.asax is likely to be a forgotten step)

For instance, is there a way the MyDependency class can "hook" into the pipeline without the needing to edit the Global.asax?

您应该查看 WebActivator。来自 wiki：

WebActivator 是一个 NuGet 包，允许其他包轻松地
将启动和关闭代码引入 Web 应用程序。这给出了
比修改 global.asax 更干净的解决方案
许多包的启动逻辑。

本质上，你需要类似的东西：

using System;

[assembly: WebActivator.PreApplicationStartMethod(typeof(MyDependency), "Initialize")]
public static class MyDependency
{
    public static void Initialize()
    {
        // Perform some I/O...
    }
}

You should look at WebActivator. From the wiki:

WebActivator is a NuGet package that allows other packages to easily
bring in Startup and Shutdown code into a web application. This gives
a much cleaner solution than having to modify global.asax with the
startup logic from many packages.

Essentially, you'll need something like:

using System;

[assembly: WebActivator.PreApplicationStartMethod(typeof(MyDependency), "Initialize")]
public static class MyDependency
{
    public static void Initialize()
    {
        // Perform some I/O...
    }
}
