我在MVC网站上使用LightInject和ServiceProvider适配器。我正在尝试将它连接到MiniProfiler,但我没有太多运气。 MiniProfiler似乎正在捕获MVC Controller Lifecycle,但不是任何依赖项: Mini Profiler Image Profiling Dump (I was debugging during this screenshot - ignore the 61,744 ms duration)
这就是我初始化容器的方式:
protected override IServiceProvider BuildServiceProvider(IServiceCollection serviceCollection)
{
var container = new ServiceContainer();
container.Register<IInterceptor, MiniProfilerInterceptor>();
foreach (var descriptor in serviceCollection)
{
if (descriptor.ServiceType.AssemblyQualifiedName.StartsWith("ProjectName"))
{
container.Intercept(s => s.ServiceType == descriptor.ServiceType, i => i.GetInstance<IInterceptor>());
}
}
var serviceProvider = container.CreateServiceProvider(serviceCollection);
return serviceProvider;
}
拦截器如下所示:
public class MiniProfilerInterceptor : IInterceptor
{
public object Invoke(IInvocationInfo invocation)
{
var profiler = MiniProfiler.Current;
var returnType = invocation.Method.ReturnType;
using (profiler.Step(invocation.Proxy.GetType().Name + ":" + invocation.Method.Name))
{
return invocation.Proceed();
}
}
}
这是控制器和测试依赖:
public class SomeDependencyController : Controller
{
private readonly SomeDependency _dependency;
public SomeDependencyController(SomeDependency dependency)
{
_dependency = dependency;
}
public MvcHtmlString DoSomething()
{
_dependency.DoSomething();
return new MvcHtmlString("Did it");
}
public ActionResult DoRender()
{
_dependency.DoSomething();
return View("DoRender");
}
}
public class SomeDependency
{
public void DoSomething()
{
Thread.Sleep(1000);
}
}
我在拦截器代码中抛出一个断点。永远不会为SomeDependency
的任何内容输入拦截器,但它会为SomeDependencyController
答案 0 :(得分:0)
我明白了。我需要制作方法virtual
。
来自LightInject的文档:
任何标记为虚拟的成员都可以被截获。
我错过了那一部分。希望这可以帮助将来的某个人。
