在我的项目中，我有两个DataStore (更好的SharedPref API )。我有AuthDataStore和UserDataStore，有单独的包。我想把这两个DataStores分别注入repositories中。我用了匕首希尔特

implementation 'com.google.dagger:hilt-android:2.40.5'
    kapt 'com.google.dagger:hilt-android-compiler:2.40.5'
    kapt 'androidx.hilt:hilt-compiler:1.0.0'
    implementation 'androidx.hilt:hilt-navigation-compose:1.0.0'

这是我的DataStoreModule

@Module
@InstallIn(SingletonComponent::class)
object DsModule {

    @Provides
    @Singleton
    fun provideUserDataStoreSource(
        ds: DataStore<Preferences>
    ): UserDataStoreSource {
        return UserDataStoreSourceImpl(ds = ds)
    }

    @Provides
    @Named(value = Constants.USER_DS_NAME)
    @Singleton
    fun provideUserDataStore(
        @ApplicationContext context: Context
    ): DataStore<Preferences> {
        return PreferenceDataStoreFactory.create(
            produceFile = {
                context.preferencesDataStoreFile(Constants.USER_DS_NAME)
            }
        )
    }

    @Provides
    @Singleton
    fun provideAuthDataStoreSource(
        ds: DataStore<Preferences>
    ): AuthDataStore {
        return AuthDataStoreSourceImpl(ds = ds)
    }

    @Provides
    @Named(value = Constants.AUTH_DS_NAME)
    @Singleton
    fun provideAuthDataStore(
        @ApplicationContext context: Context
    ): DataStore<Preferences> {
        return PreferenceDataStoreFactory.create(
            produceFile = {
                context.preferencesDataStoreFile(Constants.AUTH_DS_NAME)
            }
        )
    }
}

这是我的宝库。

open class AuthDataStoreSourceImpl @Inject constructor(
    @Named(value = Constants.AUTH_DS_NAME) private val ds: DataStore<Preferences>
) : AuthDataStore {

    companion object {
        val AUTH_STATE = booleanPreferencesKey("com.galaxytechno.auth_state")
    }

    override suspend fun putAuthFlag(isLoggedIn: Boolean) {
        ds.edit {
            it[AUTH_STATE] = isLoggedIn
        }
    }

    override suspend fun pullAuthFlag(): Flow<Boolean> {
        return ds.data
            .catch { exception ->
                if (exception is IOException) emit(emptyPreferences()) else throw exception

            }.map {
                it[AUTH_STATE] ?: false
            }
    }

}

open class UserDataStoreSourceImpl @Inject constructor(
    @Named(value = Constants.USER_DS_NAME) private val ds: DataStore<Preferences>
) : UserDataStoreSource {

    companion object {
        val ACCESS_TOKEN = stringPreferencesKey("com.galaxytechno.user.access_token")
        val REFRESH_TOKEN = stringPreferencesKey("com.galaxytechno.user.refresh_token")
    }

    override suspend fun putAccessToken(token: String) {
        ds.edit {
            it[ACCESS_TOKEN] = token
        }
    }

    override suspend fun pullAccessToken(): Flow<String> {
        return ds.data
            .catch { exception ->
                if (exception is IOException) emit(emptyPreferences()) else throw exception

            }
            .map {
                it[ACCESS_TOKEN] ?: "empty_access_token"
            }
    } }

这些是我的主要回复：

class AuthRepositoryImpl @Inject constructor(
    private val api: AuthApiService,
    @Named(value = Constants.AUTH_DS_NAME) private val ds: AuthDataStore,
    @Qualifier.Io private val io: CoroutineDispatcher
) : AuthRepository {
    override suspend fun login(
        mobileNumber: String,
        password: String
    ): Flow<RemoteResource<LoginDTO>> {
        return flow {
            emit(
                safeApiCall {
                    api.login(
                        mobileNumber = mobileNumber,
                        password = password
                    )
                }
            )
        }.flowOn(io)
    }

    override suspend fun putAuthFlag(isLoggedIn: Boolean) {
        withContext(io){
            ds.putAuthFlag(isLoggedIn = isLoggedIn)
        }
    }

    override suspend fun pullAuthFlag(): Flow<Boolean> {
        return ds.pullAuthFlag()
    }
}

class UserRepositoryImpl @Inject constructor(
    private val api: UserApiService,
    private val db: UserDatabase,
    @Named(value = Constants.USER_DS_NAME) private val ds : UserDataStoreSource,
    @Qualifier.Io private val io: CoroutineDispatcher
) : UserRepository {

}

这是我的回购模块；

@Module
@InstallIn(SingletonComponent::class)
object RepositoryModule {

    @Provides
    @Singleton
    fun provideUserRepository(
        api: UserApiService,
        db: UserDatabase,
        @Named(value = Constants.USER_DS_NAME) ds : UserDataStoreSource,
        @Qualifier.Io io: CoroutineDispatcher
    ): UserRepository {
        return UserRepositoryImpl(
            api = api,
            db = db,
            ds = ds,
            io = io
        )
    }

    @Provides
    @Singleton
    fun provideAuthRepository(
        api: AuthApiService,
        @Named(value = Constants.AUTH_DS_NAME) ds: AuthDataStore,
        @Qualifier.Io io: CoroutineDispatcher
    ): AuthRepository {
        return AuthRepositoryImpl(
            api = api,
            ds = ds,
            io = io
        )
    }

}

我对此一无所知。我经常读刀柄文件。但我对匕首缺乏了解。请帮帮我。

根据[Dagger/MissingBinding]的说法，Dagger正在寻找一个@Named("auth.chat.ds") AuthDataStore。这意味着您需要一个精确的绑定匹配，通常使用@Binds或@Provides提供，包括精确的类名、精确的泛型和具有完全相同注释值的精确@Qualifier注释(如@Named)。

但是，您的DataStoreModule列出了：

@Provides
@Singleton                                  // No @Named annotation
fun provideAuthDataStoreSource(
    ds: DataStore<Preferences>
): AuthDataStore {                          // AuthDataStore
    return /* ... */
}

@Provides
@Named(value = Constants.AUTH_DS_NAME)      // @Named("auth.chat.ds")
@Singleton
fun provideAuthDataStore(
    @ApplicationContext context: Context
): DataStore<Preferences> {                 // DataStore<Preferences>
    return /* ... */
}

因此，您在provideAuthModule中的参数@Named(value = Constants.AUTH_DS_NAME) ds: AuthDataStore不匹配。它既不是@Named(AUTH_DS_NAME) DataStore<Preferences>，也不是未命名/不合格的AuthDataStore。

删除您的@Named，您应该会没事的：

@Provides
@Singleton
fun provideAuthRepository(
    api: AuthApiService,
    /* @Named(value = Constants.AUTH_DS_NAME) */ ds: AuthDataStore,
    /* ^-------------remove-----------------^ */
    @Qualifier.Io io: CoroutineDispatcher
): AuthRepository
