如何使用scan
扩展在程序集中注册所有接口而不在ASP.NET Core 2中单独写入?
在StructureMap中:
Scan(_ =>
{
// Declare which assemblies to scan
_.Assembly("StructureMap.Testing");
});
在Scrutor中:
collection.Scan(scan => scan
// We start out with all types in the assembly of ITransientService
.FromAssemblyOf<ITransientService>()
// AddClasses starts out with all public, non-abstract types in this
// assembly. These types are then filtered by the delegate passed to the
// method. In this case, we filter out only the classes that are assignable
// to ITransientService.
.AddClasses(classes => classes.AssignableTo<ITransientService>())
// We then specify what type we want to register these classes as.
// In this case, we want to register the types as all of its implemented
// interfaces. So if a type implements 3 interfaces; A, B, C, we'd end
// up with three separate registrations.
.AsImplementedInterfaces()
// And lastly, we specify the lifetime of these registrations.
.WithTransientLifetime()
// Here we start again, with a new full set of classes from the assembly
// above. This time, filtering out only the classes assignable to
// IScopedService.
.AddClasses(classes => classes.AssignableTo<IScopedService>())
// Now, we just want to register these types as a single interface,
// IScopedService.
.As<IScopedService>()
// And again, just specify the lifetime.
.WithScopedLifetime());
这将默认注册所有实现某些接口的类,如StructureMap所做的那样:
services.Scan(scan => scan
.FromAssemblyOf<IService>()
.AddClasses()
.AsImplementedInterfaces()
.WithTransientLifetime());
