依赖注入 – 基于约定的依赖注入与Ninject 3.0.0

前端之家收集整理的这篇文章主要介绍了依赖注入 – 基于约定的依赖注入与Ninject 3.0.0前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我的解决方案中有两个项目:域项目和MVC3 Web项目(例如MyApp.Domain和MyApp.Web).以前,当使用Ninject.Extensions.Conventions ver. 2,我能够在NinjectMVC3.cs文件中使用以下语句,并且在我的解决方案(网络和域)中都需要正确注入所需的依赖关系(例如,IFoo自动绑定到Foo).
kernel.Scan(x =>
{
  x.FromAssembliesMatching("*");
  x.BindWith<DefaultBindingGenerator>();
});@H_301_2@ 
 

我刚刚升级到Ninject 3.0.0(预发行版)和Ninject.Extensions.Conventions 3.0.0(另一个预发行版),但基于约定的绑定的语法已更改.我已经弄清楚,我可以使用以下语句与新版本,但它只会自动绑定在MyApp.Web中的约会接口,而不是在MyApp.Domain中.以前的版本绑定在整个应用程序的界面.

kernel.Bind(x => x
    .FromThisAssembly()
    .SelectAllClasses()
    .BindToAllInterfaces());@H_301_2@ 
 

任何线索我如何配置新的Ninject版本的基于约定的绑定?我假设它与指定程序集有关,但我已经尝试使用FromAssembliesMatching(“*”),并且它会失败的一切.

– 编辑以在RegisterServices方法显示我现有的代码

private static void RegisterServices(IKernel kernel)
{
  // This code used to work with v.2 of Ninject.Extensions.Conventions
  // kernel.Scan(x =>
  // {
  //   x.FromAssembliesMatching("*");
  //   x.BindWith<DefaultBindingGenerator>();
  // });

  // This is the new v3 code that automatically injects dependencies but only for interfaces in MyApp.Web,not MyApp.Domain
  kernel.Bind(x => x.FromThisAssembly().SelectAllClasses().BindToAllInterfaces()); 

  // I tried this code,but it throws "Error activating IDependencyResolver" at "bootstrapper.Initialize(CreateKernel)"
  // kernel.Bind(x => x.FromAssembliesInPath(AppDomain.CurrentDomain.RelativeSearchPath).SelectAllClasses().BindToAllInterfaces());

  // These are dependencies in MyApp.Web that ARE being bound properly by the current configuration
  // kernel.Bind<IMemberQueries>().To<MemberQueries>();
  // kernel.Bind<IGrantApplicationQueries>().To<GrantApplicationQueries>();
  // kernel.Bind<IMailController>().To<MailController>();

  // These are dependencies in MyApp.Domain that ARE NOT being bound properly by the current configuration,so I have to declare them manually 
  // They used to be injected automatically with version 2 of the conventions extention
  kernel.Bind(typeof(IRepository<>)).To(typeof(Repository<>)).InRequestScope();
  kernel.Bind<IUnitOfWork>().To<UnitOfWork>().InRequestScope();
  kernel.Bind<IMemberServices>().To<MemberServices>();
  kernel.Bind<IGrantApplicationServices>().To<GrantApplicationServices>();

  // These are dependencies that SHOULD NOT be bound by convention as they require a different scope or have unique naming
  kernel.Bind(typeof(EfDbContext)).ToSelf().InRequestScope();
  kernel.Bind<IConfigurationProvider>().To<WebConfigConfigurationProvider>().InSingletonScope();
  kernel.Bind<IAuthorizationProvider>().To<MyAppAuthorizationProvider>();
  kernel.Bind<IPrincipal>().ToMethod(ctx => HttpContext.Current.User).InRequestScope();
  kernel.Bind<IGrantApplicationDocumentServices>().To<MySpecialNameGrantAplicationDocumentServices>().InRequestScope();
}@H_301_2@
相当于:
kernel.Bind(x => x
    .FromAssembliesMatching("*")
    .SelectAllClasses()
    .BindDefaultInterface());@H_301_2@
