目前,我正在学习更多关于caliburn.micro的知识,它令人惊叹。
在我的带有一些导航的小演示项目中,有MEF和EventAggregator。
因为我想在一个已经在使用unity的项目中使用caliburn.micro,所以我想使用Unity for DI。
如何将引导程序设置为使用Unity?
除了MindScape教程和codeplex页面上的教程之外,任何好的教程都是非常受欢迎的。(除了我没有看到正确的人来处理这个案例)

在使用Boostrapper<T>时,您必须在引导程序中重写4个方法来连接IoC容器:
Configure()这通常是初始化容器并注册所有dependencies.
GetInstance(string, Type)的地方按类型和键检索对象-据我所知,框架通常用它来检索视图模型、常规依赖关系等。因此,在这里,您的容器必须以某种方式获得一个基于类型和/或Type (通常是类型,当您使用视图优先绑定将模型连接到视图时使用字符串)的实例。通常容器都有类似的内置方法,它们开箱即用,或者只需要一点adjustment.
GetAllInstances(Type)对象集合的检索(仅按类型)-同样,根据我的经验,这通常用于views.
BuildUp(object)的Caliburn.Micro可以对对象进行属性注入的方法。
如果你感兴趣,我有一个使用SimpleInjector (或Autofac)的样本,不幸的是我没有使用Unity的经验。

示例时间!这一个使用的是SimpleInjector。
public class MainViewModel
{
//...
}
public class ApplicationBootstrapper : Bootstrapper<MainViewModel>
{
private Container container;
protected override void Configure()
{
container = new Container();
container.Register<IWindowManager, WindowManager>();
//for Unity, that would probably be something like:
//container.RegisterType<IWindowManager, WindowManager>();
container.RegisterSingle<IEventAggregator, EventAggregator>();
container.Verify();
}
protected override object GetInstance(string key, Type service)
{
// Now, for example, you can't resolve dependency by key in SimpleInjector, so you have to
// create the type out of the string (if the 'service' parameter is missing)
var serviceType = service;
if(serviceType == null)
{
var typeName = Assembly.GetExecutingAssembly().DefinedTypes.Where(x => x.Name == key).Select(x => x.FullName).FirstOrDefault();
if(typeName == null)
throw new InvalidOperationException("No matching type found");
serviceType = Type.GetType(typeName);
}
return container.GetInstance(serviceType);
//Unity: container.Resolve(serviceType) or Resolve(serviceType, name)...?
}
protected override IEnumerable<object> GetAllInstances(Type service)
{
return container.GetAllInstances(service);
//Unity: No idea here.
}
protected override void BuildUp(object instance)
{
container.InjectProperties(instance);
//Unity: No idea here.
}

我发现Wiki for CM非常有用,而且来自Unity/CSL背景的Bootstrapper<TRootModel>方法名称和签名都很直观。
我想分享我自己的UnityBootstrapper<TRootModel>类,它利用了Unity3,它很小,干净,做了你想要的事情。
/// <summary>

/// <para>You can subclass this just as you would Caliburn's Bootstrapper</para>
/// <para>http://caliburnmicro.codeplex.com/wikipage?title=Customizing%20The%20Bootstrapper</para>
/// </summary>
/// <typeparam name="TRootModel">Root ViewModel</typeparam>
public class UnityBootstrapper<TRootModel>
: Bootstrapper<TRootModel>
where TRootModel : class, new()
{
protected UnityContainer Container
{
get { return _container; }
set { _container = value; }
}
private UnityContainer _container = new UnityContainer();
protected override void Configure()
{
if (!Container.IsRegistered<IWindowManager>())
{
Container.RegisterInstance<IWindowManager>(new WindowManager());
}
if (!Container.IsRegistered<IEventAggregator>())
{
Container.RegisterInstance<IEventAggregator>(new EventAggregator());
}
base.Configure();
}
protected override void BuildUp(object instance)
{
instance = Container.BuildUp(instance);
base.BuildUp(instance);
}
protected override IEnumerable<object> GetAllInstances(Type type)
{
return Container.ResolveAll(type);
}
protected override object GetInstance(Type type, string name)
{
var result = default(object);
if (name != null)
{
result = Container.Resolve(type, name);
}
else
{
result = Container.Resolve(type);
}
return result;
}
}您可以直接实例化它,提供有效的泛型类型参数,或者您可以子类化和自定义诸如Lifetime Managers之类的东西:
public class AppBootstrapper
: UnityBootstrapper<ViewModels.AppViewModel>
{
protected override void Configure()
{
// register a 'singleton' instance of the app view model
base.Container.RegisterInstance(
new ViewModels.AppViewModel(),
new ContainerControlledLifetimeManager());
// finish configuring for Caliburn
base.Configure();
}
