Unity 2 属性注入，如何将配置转换为流畅的语法？

发布于 2024-09-17 23:44:12 字数 770 浏览 5 评论 0原文

我有一个 httpHandler 并使用 Unity 2 我想将依赖项注入到我的 HttpHandler 中。

我的代码如下所示：

public class MyHandler : BaseHandler
{

    public MyHandler()
    {
    }

    public IConfigurationManager Configuration
    {
        get;
        set;
    }

    ...
}

使用 web.config 我会像这样配置它（为了简单起见，省略了配置的其余部分）：

<type type="MyHandler">
   <typeConfig extensionType="Microsoft.Practices.Unity.Configuration.TypeInjectionElement, Microsoft.Practices.Unity.Configuration">
      <property name="Configuration" propertyType="IConfigurationManager">
        <dependency/>
      </property>
   </typeConfig>
</type>

我将如何使用流畅的语法做同样的事情？到目前为止，我尝试过的所有操作都会在处理程序触发时将属性设置为 null。

谢谢

I have a httpHandler and using Unity 2 I would like to inject a dependency into my HttpHandler.

My code looks like:

public class MyHandler : BaseHandler
{

    public MyHandler()
    {
    }

    public IConfigurationManager Configuration
    {
        get;
        set;
    }

    ...
}

Using the web.config I would configure it like this (left out the rest of the config for simplicity) :

<type type="MyHandler">
   <typeConfig extensionType="Microsoft.Practices.Unity.Configuration.TypeInjectionElement, Microsoft.Practices.Unity.Configuration">
      <property name="Configuration" propertyType="IConfigurationManager">
        <dependency/>
      </property>
   </typeConfig>
</type>

How would I go about doing the same thing using fluent syntax? Everything I have tried so far leaves the property set to null when the handler fires.

Thanks

自 Unity 1.2 发布以来，ConfigureInjectionFor 已过时。

这应该有效：

container.RegisterType<MyHandler>(
    new InjectionProperty("Configuration"));

ConfigureInjectionFor has been obsolete since Unity 1.2 was released.

This should work:

container.RegisterType<MyHandler>(
    new InjectionProperty("Configuration"));

您必须调用 ConfigureInjectionFor 方法。

myContainer.Configure<InjectedMembers>()
    .ConfigureInjectionFor<MyHandler>(
            new InjectionProperty("Configuration", 
                                  new ResolvedParameter<IConfigurationManager>())
                                 )
            )

编辑：

这是处理程序工厂的示例。它允许您创建处理程序

 class HandlerFactory : IHttpHandlerFactory
    {
        public IHttpHandler GetHandler(HttpContext context, string requestType, String url, String pathTranslated)
        {
            return MyContainerProvider.Container.Resolve<MyHandler>();
        }
        public void ReleaseHandler(IHttpHandler handler)
        {
        }
        public bool IsReusable
        {
            get { return false; }
        }
    }

然后，您必须在 Web 应用程序中注册工厂（以允许 IIS 找到它）。您可以在此处找到更多详细信息。

You have to call the ConfigureInjectionFor method.

myContainer.Configure<InjectedMembers>()
    .ConfigureInjectionFor<MyHandler>(
            new InjectionProperty("Configuration", 
                                  new ResolvedParameter<IConfigurationManager>())
                                 )
            )

EDIT:

Here is an example of Handler factory. It allow you to create your handler

 class HandlerFactory : IHttpHandlerFactory
    {
        public IHttpHandler GetHandler(HttpContext context, string requestType, String url, String pathTranslated)
        {
            return MyContainerProvider.Container.Resolve<MyHandler>();
        }
        public void ReleaseHandler(IHttpHandler handler)
        {
        }
        public bool IsReusable
        {
            get { return false; }
        }
    }

Then, you have to register the factory in your web application (to allow IIS to find it). You can find more details here.
