长话短说，尝试利用Google的良好做法。我为Di计划使用Dagger 2犯了一个错误。现在我被困住了。我跟随Sunflower architecture 我正在尝试将本地数据（ld）源和远程数据（rd）源分开，同时尽可能保留我拥有的体系结构。我目前有2个数据源ld和rd实现数据源接口。而且我的存储库只能识别该接口中的功能。在googles示例中，它们在两个数据源中共享相同的功能，而我的项目与此不同，它们应该具有不同的功能。 （Ld应该在数据库中插入引号，而远程应该只获取引号）

我尝试创建一个新的接口，该接口实现了数据源，但特定于本地数据源，但是该接口不起作用，请不断从dagger中获取丢失的绑定错误。

interface QuoteDataSource { //data source interface for both data sources

    suspend fun getQuotes(): Result<List<Quote>>

}

class DefaultQuoteRepository @Inject constructor( 
    @Applicationmodule.QuoteRemoteDataSource private val quoteRemoteDataSource: QuoteDataSource,@Applicationmodule.QuoteLocalDataSource private val quoteLocalDataSource: QuoteDataSource,private val ioDispatcher: CoroutineDispatcher = Dispatchers.IO
) : BaseRepository(),QuoteRepository {

 @JvmStatic
    @Singleton
    @QuoteRemoteDataSource
    @Provides
    fun provideQuoteRemoteDataSource(
        jsonNetworkService: JsonNetworkService
    ): QuoteDataSource {
        return QuoteRemoteDataSource(jsonNetworkService.apiService)
    }

        database: LocalQuoteDataBase,ioDispatcher: CoroutineDispatcher
    ): QuoteDataSource {
        return QuoteLocalDataSource(
            database.quotesDao(),ioDispatcher
        )
    }

class QuoteLocalDataSource constructor( // for fetching locally stored quotes,might save favorite quootes or save the json quotes
    private val quotesDao: QuotesDao,private val ioDispatcher: CoroutineDispatcher = Dispatchers.IO
) : QuoteDataSource {

    override suspend fun getQuotes(): Result<List<Quote>> = withContext(ioDispatcher) {
        return@withContext try {
            Success(quotesDao.getQuotes())
        } catch (e: Exception) {
            Result.Error(IOException("Unable to fetch quotes!"))
        }
    }


class QuoteRemoteDataSource @Inject constructor(
    private val apiService: QuoteApi
) : QuoteDataSource {

    override suspend fun getQuotes(): Result<List<Quote>> {
        val response = apiService.getQuotes().await()
        try {
            if (response.isSuccessful)
                if(!response.body().isnullOrEmpty())
                return Result.Success(response.body()) as Result<List<Quote>>
            return Result.Error(IOException("Error occurred during fetching quotes!"))
        } catch (e: Exception) {
            Result.Error(IOException("Unable to fetch quotes!"))
        }
        return Result.Error(IOException("Unable to fetch quotes!"))
    }

我正设法使localdata源具有其自己的功能，这些功能可以被默认报价存储库识别。好像我只是将函数添加到本地语言一样，它们对存储库将不可用。
