Logging 尝试使用DynamicProxy为StructureMap创建日志侦听器
我正在尝试记录从UI(DNN模块)到它使用的一些不同服务的调用,以了解人们是如何与站点交互的。我正在使用StructureMap 2.5.3.0和Log4Net 我在单独的类/实例对上工作得很好,但我必须这样配置:Logging 尝试使用DynamicProxy为StructureMap创建日志侦听器,logging,structuremap,castle-dynamicproxy,Logging,Structuremap,Castle Dynamicproxy,我正在尝试记录从UI(DNN模块)到它使用的一些不同服务的调用,以了解人们是如何与站点交互的。我正在使用StructureMap 2.5.3.0和Log4Net 我在单独的类/实例对上工作得很好,但我必须这样配置: ObjectFactory.Configure(ce => ce.ForRequestedType<IRegService>() .TheDefaultIsConcreteType<RegService>()

这是可行的,但有几个问题:
public class ApplicationRegistry : Registry
{
public ApplicationRegistry()
{
RegisterInterceptor(new LoggingInterceptor());
Scan(scanner =>
{
scanner.TheCallingAssembly();
var codeBase = System.Reflection.Assembly.GetExecutingAssembly().CodeBase.Replace("file:///", String.Empty);
codeBase = codeBase.Substring(0, codeBase.LastIndexOf("/"));
scanner.AssembliesFromPath(codeBase);
scanner.WithDefaultConventions();
scanner.LookForRegistries();
});
}
}
public class LoggingInterceptor :TypeInterceptor
{
public object Process(object target, IContext context)
{
var newTarget = target;
if (context.BuildStack.Current != null && context.BuildStack.Current.RequestedType != null)
{
newTarget = LoggingEnrichment.InterfaceLogger(context.BuildStack.Current.RequestedType, target);
}
return newTarget;
}
public bool MatchesType(Type type)
{
return type.Name.EndsWith("Service", StringComparison.OrdinalIgnoreCase);
}
}
但是我遇到了一个问题,调用Process
给了我一个类,这个类没有实现构建上下文定义的接口。这导致必须将接口记录器的实现更改为
public static object InterfaceLogger(Type iinterface, object concrete)
{
if(!iinterface.IsAssignableFrom(concrete.GetType())) return concrete;
var dynamicProxy = new ProxyGenerator();
var interfaceProxy = dynamicProxy.CreateInterfaceProxyWithTarget(iinterface, concrete, new LogInterceptor());
return interfaceProxy;
}
返回接口proxy上的断点代码>从未到达,这表示context.BuildStack.Current.RequestedType
未返回正确的接口。奇怪的是,我所有的类似乎都被正确注入
此外,即使这是工作,我仍然有一个问题,就是只想拦截来自UI层的调用
我正在寻找解决前两个问题的方法,以及我使用TypeInterceptor的错误之处。我使用约定解决了这个问题。以下是我为实现这一目标所采取的步骤
首先,我对指定的程序集进行了扫描,我将在其中附加装饰程序
x.Scan(scanner =>
{
scanner.Assembly("MyProject.Services"); // Specific assemblyname
scanner.Convention<ServiceRegistrationConvention>();
scanner.WithDefaultConventions();
scanner.LookForRegistries();
});
我使用与您相同的LoggingEnrichment类
希望这能解决您提到的问题。您好,遇到了同样的问题。你解决了这个问题吗?嗨,我下面的答案解决了你的问题吗?Tnx。
public class ServiceRegistrationConvention : IRegistrationConvention
{
public void Process(Type type, Registry registry)
{
var handlerInterfaces = (from t in type.GetInterfaces()
where
(t.Namespace.StartsWith("MyProject.UIServices", StringComparison.OrdinalIgnoreCase)
|| t.Namespace.StartsWith("MyProject.Services", StringComparison.OrdinalIgnoreCase))
select t);
foreach (var handler in handlerInterfaces)
{
registry.For(handler)
.EnrichWith((ctx, orig) => LoggingEnrichment.InterfaceLogger(handler, orig));
}
}
}
