会员重启与简单的喷油器替代Ninject

问题描述

我需要添加成员重新启动（RavenDb）到使用国际奥委会简单喷油器项目

I need add membership reboot (RavenDb) into the project that use IOC Simple Injector

Ninject实施

var config = MembershipRebootConfig.Create();
kernel.Bind<MembershipRebootConfiguration<HierarchicalUserAccount>>().ToConstant(config);
kernel.Bind<UserAccountService<HierarchicalUserAccount>>().ToSelf();   kernel.Bind<AuthenticationService<HierarchicalUserAccount().To<SamAuthenticationService<HierarchicalUserAccount>>();
kernel.Bind<IUserAccountRepository<HierarchicalUserAccount>>().ToMethod(ctx => new BrockAllen.MembershipReboot.RavenDb.RavenUserAccountRepository("RavenDb"));
kernel.Bind<IUserAccountQuery>().ToMethod(ctx => new BrockAllen.MembershipReboot.RavenDb.RavenUserAccountRepository("RavenDb"));

简单的注射器实施

Simple Injector implementation

container.Register(MembershipRebootConfig.Create);
container.Register<UserAccountService<HierarchicalUserAccount>>();
container.Register<AuthenticationService<HierarchicalUserAccount>, SamAuthenticationService<HierarchicalUserAccount>>();
container.Register<IUserAccountRepository<HierarchicalUserAccount>>(() => new RavenUserAccountRepository("RavenDb"), Lifestyle.Singleton);
container.Register<IUserAccountQuery>(() => new RavenUserAccountRepository("RavenDb"));

在行

container.Register<UserAccountService<HierarchicalUserAccount>>();

我有一个错误
对于容器能够创建UserAccountService，它应该包含一个公共构造函数，但它有2个。
参数名：TConcrete

I have an errorFor the container to be able to create UserAccountService, it should contain exactly one public constructor, but it has 2.Parameter name: TConcrete

感谢您的帮助。

推荐答案

简单的喷油器迫使你让你的组件有一个单一的公共构造方法，因为其的。

Simple Injector forces you to let your components to have one single public constructor, because having multiple injection constructors is an anti-pattern.

在情况下， UserAccountService 是code库的一部分，你应该删除不应该被用于自动布线构造。

In case the UserAccountService is part of your code base, you should remove the constructor that should not be used for auto-wiring.

在情况下， UserAccountService 是一个可重用库的一部分，你应该说明的。在这种情况下，你应该退回到自己的布线类型，让你的code调用到适当的构造函数，例如：

In case the UserAccountService is part of a reusable library, you should prevent using your container's auto-wiring capabilities in that case as described here. In that case you should fallback to wiring the type yourself and let your code call into the proper constructor, for instance:

container.Register<UserAccountService<HierarchicalUserAccount>>(() =>
    new UserAccountService<HierarchicalUserAccount>(
        container.GetInstance<MembershipRebootConfiguration<HierarchicalUserAccount>>(),
        container.GetInstance<IUserAccountRepository<HierarchicalUserAccount>>()));
