Question

I have an interface, called IRepository, with two implementations:

SqlRepository
SqlDualWriter

第一项执行工作是定期实施T类物体。它依赖SqlConnectionStringProvider(提供联系人,如名称所示,并作为建筑参数,使用一个显示姓名的链接)。

第二项是另一项在内部使用两种储存地:

public class SqlDualWriter<T> : IRepository<T>
{
    private readonly IRepository<T> _primaryRepository;
    private readonly IRepository<T> _secondaryRepository;

    public SqlDualWriter(
        IRepository<T> primaryRepository,
        IRepository<T> secondaryRepository)
    {
        _primaryRepository = primaryRepository;
        _secondaryRepository = secondaryRepository;
    iii

我想要实现的是组合结构,以便在要求进行保存时,它将:

resolve IRepository to an instance of SqlDualWriter
resolve the two inner repositories to type SqlRepository
for the two SqlRepository objects instantiated at step 2 I need to resolve the SqlConnectionStringProvider in a different way (providing different string parameters in the constructor)

I have no idea how to achieve this. Is there a way to do it with Attributes or other types of configuration?

I m 采用结构Map 2.6.2.0。

我找到了两种解决办法:

• 利用斜线标出结构,说明如何建立SqlDualWriter 保存法院,解决托存的依赖:

x.For<IRepository<Type>>().Use(
        ()=> new SqlDualWriterRepository<Type>(
            NewPrimaryRepositoryInstance<Type>(),
            NewSecondaryRepositoryInstance<Type>()));

采用“Ctor<”和“gt”明确指明每一建筑依赖者应如何即时:

x.For<IRepository<Type>>().Use<SqlDualWriterRepository<Type>>()
        .Ctor<IRepository<Type>>("primaryRepository").Is(NewPrimaryRepositoryInstance<Type>())
        .Ctor<IRepository<Type>>("secondaryRepository").Is(NewSecondaryRepositoryInstance<Type>());

在上述两个例子中,新的遗产保存和新的第二代保存方法都建立了具有适当SqlConnectionStringProvider配置的初级和二级储存库。

实现这一点也许有更好的办法,但这些解决办法现在确实如此。
