Castle Windsor没有注入类的依赖关系

UserRespository：

public class UserRepository : Repository<User>, IUserRepository 
{ 
    public IAuthenticationContext authenticationContext; 

    public UserRepository(IAuthenticationContext authenticationContext) 
     :base(authenticationContext as DbContext) { } 

    public User GetByUsername(string username) 
    { 
     return authenticationContext.Users.SingleOrDefault(u => u.Username == username); 
    } 
}

UserService：

public class UserService : IUserService 
{ 
    private IUserRepository _userRepository; 

    public UserService(IUserRepository userRepository) 
    { 
     _userRepository = userRepository; 
    } 

    public IEnumerable<User> GetAll() 
    { 
     return _userRepository.GetAll(); 
    } 

    public User GetByUsername(string username) 
    { 
     return _userRepository.GetByUsername(username); 
    } 
}

现在，当我注入UserService它的_userRepository为空。任何想法我需要配置让它正确注入存储库。

我有以下安装代码：

public class RepositoriesInstaller : IWindsorInstaller 
{ 
    public void Install(IWindsorContainer container, IConfigurationStore store) 
    { 
     container.Register(Types.FromAssemblyNamed("DataAccess") 
      .Where(type => type.Name.EndsWith("Repository") && !type.IsInterface) 
      .WithServiceAllInterfaces() 
      .Configure(c =>c.LifestylePerWebRequest())); 

     //AuthenticationContext authenticationContext = new AuthenticationContext(); 
    } 
} 

public class ServicesInstaller : IWindsorInstaller 
{ 
    public void Install(IWindsorContainer container, IConfigurationStore store) 
    { 
     container.Register(Types.FromAssemblyNamed("Services") 
      .Where(type => type.Name.EndsWith("Service") && !type.IsInterface) 
      .WithServiceAllInterfaces() 
      .Configure(c => c.LifestylePerWebRequest())); 
    } 
}

我怎么会去注册的具体的DbContext的

public class AuthenticationContext : DbContext 
{ 
    public AuthenticationContext() : base("name=Authentication") 
    { 
     Configuration.LazyLoadingEnabled = false; 
     Configuration.ProxyCreationEnabled = false; 
    } 

    public DbSet<User> Users { get; set; } 
    public DbSet<Role> Roles { get; set; } 
}

UPDATE

当我删除默认UserSe中的构造函数起动转矩大，我得到以下错误：

Castle.MicroKernel.Handlers.HandlerException: Can't create component 'DataAccess.Repositories.UserRepository' as it has dependencies to be satisfied. 'DataAccess.Repositories.UserRepository' is waiting for the following dependencies: - Service 'DataAccess.AuthenticationContext' which was not registered.

你有没有尝试删除默认的构造函数来自'UserService'？拥有多个构造函数[是一种反模式]（https://www.cuttingedge.it/blogs/steven/pivot/entry.php?id=97）。 – Steven

如果我删除构造函数，UserService将不会注入到我的控制器中。 – Wilds

那么当你删除默认的构造函数时你得到的错误是什么？ – Steven

基于关闭您的例外在你的“UPDATE”你需要这样温莎知道如何创建它注册AuthenticationContext类。

container.Register(
    Component.For<AuthenticationContext>() 
     .ImplementedBy<AuthenticationContext>());

然而，根据关闭它取决于接口IAuthenticationContext（而不是AuthenticationContext）上，所以你会指定接口的实现UserRepository.cs代码：

container.Register(
    Component.For<IAuthenticationContext>() 
     .ImplementedBy<AuthenticationContext>());
