Dependency injection 是否可以将依赖项注入与Umbraco 7 ContentService事件处理程序一起使用？

我在MVC项目中使用了Umbraco 7.1.1，并将其配置为使用依赖项注入（在我的例子中是Castle.Windsor）。我还使用NServiceBus发送消息等，它工作得很好

我现在正尝试挂接ContentService Published事件—尝试并发布一个NServiceBus事件，以提醒其他服务内容已更改。我想做的是这样的：

public class ContentPublishedEventHandler : ApplicationEventHandler
{
    public IBus Bus { get; set; }

    public ContentPublishedEventHandler()
    {
        ContentService.Published += ContentServiceOnPublished;
    }

    private void ContentServiceOnPublished(IPublishingStrategy sender, PublishEventArgs<IContent> publishEventArgs)
    {
        Bus.Publish<ContentUpdatedEvent>(e =>
        {
            e.UpdatedNodeIds = publishEventArgs.PublishedEntities.Select(c => c.Id);
        });
    }
}

public class ContentPublishedEventHandler : ApplicationEventHandler
{
    public IBus Bus { get; set; }
    
    public ContentPublishedEventHandler(IBus bus)
    {
        Bus = bus;
    }

    protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        ContentService.Published += ContentServiceOnPublished;

        base.ApplicationStarting(umbracoApplication, applicationContext);
    }
        
    
    private void ContentServiceOnPublished(IPublishingStrategy sender, PublishEventArgs<IContent> publishEventArgs)
    {
        Bus.Publish<ContentUpdatedEvent>(e =>
        {
            e.UpdatedNodeIds = publishEventArgs.PublishedEntities.Select(c => c.Id);
        });
    }
}

公共类ContentPublishedEventHandler:ApplicationEventHandler
{
公共IBus总线{get；set；}
公共内容PublishedEventHandler（）
{
ContentService.Published+=ContentServiceOnPublished；
}
私有void ContentServiceOnPublished（IPPublishingStrategy发件人，PublishEventArgs PublishEventArgs）
{
发布总线（e=>
{
e、 UpdatedNodeIds=publishEventArgs.publishedenties.Select（c=>c.Id）；
});
}
}

但在这种情况下，

Bus

为空，因为我的依赖注入框架要么配置不正确，要么（我怀疑）从未调用过

---

如果依赖于对总线的静态引用，我可以让它工作，但是如果可以的话，我更愿意避免这种情况。我想做的事可能吗？Ie对这些Umbraco事件使用依赖注入？如果是这样，我需要告诉Umbraco使用Castle.Windsor创建我的事件处理程序的配置是什么？

如果您仍在寻找答案，最好在ContentPublishedEventHandler构造函数中插入依赖项，因此代码如下所示：

public class ContentPublishedEventHandler : ApplicationEventHandler
{
    public IBus Bus { get; set; }

    public ContentPublishedEventHandler()
    {
        ContentService.Published += ContentServiceOnPublished;
    }

    private void ContentServiceOnPublished(IPublishingStrategy sender, PublishEventArgs<IContent> publishEventArgs)
    {
        Bus.Publish<ContentUpdatedEvent>(e =>
        {
            e.UpdatedNodeIds = publishEventArgs.PublishedEntities.Select(c => c.Id);
        });
    }
}

public class ContentPublishedEventHandler : ApplicationEventHandler
{
    public IBus Bus { get; set; }
    
    public ContentPublishedEventHandler(IBus bus)
    {
        Bus = bus;
    }

    protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        ContentService.Published += ContentServiceOnPublished;

        base.ApplicationStarting(umbracoApplication, applicationContext);
    }
        
    
    private void ContentServiceOnPublished(IPublishingStrategy sender, PublishEventArgs<IContent> publishEventArgs)
    {
        Bus.Publish<ContentUpdatedEvent>(e =>
        {
            e.UpdatedNodeIds = publishEventArgs.PublishedEntities.Select(c => c.Id);
        });
    }
}

公共类ContentPublishedEventHandler:ApplicationEventHandler
{
公共IBus总线{get；set；}
公共内容发布器（IBus总线）
{
总线=总线；
}
受保护的覆盖无效应用程序启动（UmbracoApplicationBase umbracoApplication、ApplicationContext ApplicationContext）
{
ContentService.Published+=ContentServiceOnPublished；
base.ApplicationStarting（umbraco应用程序、applicationContext）；
}
私有void ContentServiceOnPublished（IPPublishingStrategy发件人，PublishEventArgs PublishEventArgs）
{
发布总线（e=>
{
e、 UpdatedNodeIds=publishEventArgs.publishedenties.Select（c=>c.Id）；
});
}
}
