我使用Castle.DynamicProxy和StructureMap 2.6 API进行了拦截,但现在无法使用StructureMap 3.0进行拦截.谁能帮我找到更新的文档甚至演示？我发现的一切似乎都与旧版本有关.例如StructureMap.Interceptors.TypeInterceptor接口等
解决方法
@H_403_10@ HAHAA！我做了！这是如何做：public class ServiceSingletonConvention : DefaultConventionScanner
{
public override void Process(Type type,Registry registry)
{
base.Process(type,registry);
if (type.IsInterface || !type.Name.ToLower().EndsWith("service")) return;
var pluginType = FindPluginType(type);
var delegateType = typeof(Func<,>).MakeGenericType(pluginType,pluginType);
// Create FuncInterceptor class with generic argument +
var d1 = typeof(FuncInterceptor<>);
Type[] typeArgs = { pluginType };
var interceptorType = d1.MakeGenericType(typeArgs);
// -
// Create lambda expression for passing it to the FuncInterceptor constructor +
var arg = Expression.Parameter(pluginType,"x");
var method = GetType().GetMethod("GetProxy").MakeGenericMethod(pluginType);
// Crate method calling expression
var methodCall = Expression.Call(method,arg);
// Create the lambda expression
var lambda = Expression.Lambda(delegateType,methodCall,arg);
// -
// Create instance of the FuncInterceptor
var interceptor = Activator.CreateInstance(interceptorType,lambda,"");
registry.For(pluginType).Singleton().Use(type).InterceptWith(interceptor as IInterceptor);
}
public static T GetProxy<T>(object service)
{
var proxyGeneration = new ProxyGenerator();
var result = proxyGeneration.CreateInterfaceProxyWithTarget(
typeof(T),service,(Castle.DynamicProxy.IInterceptor)(new MyInterceptor())
);
return (T)result;
}
}
这里的问题是SM 3. *允许拦截已知类型,即执行以下操作：
expression.For<IService>().Use<Service>().InterceptWith(new FuncInterceptor<IService>(service => GetProxyFrom(service)));
但是,如果您希望在自定义扫描约定中包含拦截逻辑,并且要拦截具有特定签名的所有类型实例(在我的情况下,名称以’service’结尾的类型),该怎么办？
这就是我使用Expression API和反射完成的.
此外,我在这里使用Castle.DinamicProxy为我的服务创建代理对象.
希望别人会觉得这很有帮助:)
