[英]Using ServiceStack Funq IoC: how dependencies are injected?
I have WinForm application and I want to use ServiceStack dependency injection mechanism: 我有WinForm应用程序,我想使用ServiceStack依赖注入机制:
public class AppHost : AppHostBase
{
public AppHost()
: base("MyName", typeof(AppHost).Assembly)
{
}
public override void Configure(Container container)
{
container.RegisterAutoWiredAs<AppApplicationContext, IAppApplicationContext>();
}
}
Then in some form class use it: 然后在某个表单类中使用它:
public class SomeClass : AppBaseForm
{
public IAppApplicationContext AppApplicationContext { get; set; }
public SomeClass(IAppApplicationContext appApplicationContext)
{
AppApplicationContext = appApplicationContext;
}
public SomeClass()
{
}
}
But AppApplicationContext
is always null
. 但AppApplicationContext
始终为null
。 When in parameterless constructor I write: 在无参数构造函数中,我写道:
AppApplicationContext = AppHostBase.Resolve<IAppApplicationContext>();
then every thing is OK. 然后每件事都行。 But is this right way to do that? 但这是正确的方法吗? I mean AppApplicationContext should not be resolved by IoC automatically? 我的意思是IoC不应该自动解决AppApplicationContext? And WinForm must have parameterless constructor. 并且WinForm必须具有无参数构造函数。
Rest of code: 其余代码:
private static void Main()
{
var appHost = new AppHost();
appHost.Init();
}
public interface IAppApplicationContext
{
}
public class AppApplicationContext : IAppApplicationContext
{
}
You need to call AutoWire
to have the container inject the dependancies. 您需要调用AutoWire
让容器注入依赖项。 You can use it in your WinForm app like this: 您可以在WinForm应用程序中使用它,如下所示:
public class SomeClass : AppBaseForm
{
public IAppApplicationContext AppApplicationContext { get; set; }
public SomeClass()
{
// Tell the container to inject dependancies
HostContext.Container.AutoWire(this);
}
}
When you use a regular ServiceStack service, the AutoWire
happens behind the scenes during the request pipeline when ServiceStack creates an instances of your Service. 当您使用常规ServiceStack服务时,当ServiceStack创建服务实例时, AutoWire
会在请求管道期间发生在幕后。
I have created a fully working example here . 我在这里创建了一个完整的例子 。 Note: The demo is just a console application, not WinForms but it does shows the IoC being used outside of the ServiceStack service, and it works no differently. 注意:演示只是一个控制台应用程序,而不是WinForms,但它确实显示了在ServiceStack服务之外使用的IoC,它的工作方式没有区别。
