匕首缺少与相同类型的数据存储区的绑定 [英] Dagger missing binding with same type of DataStore
本文介绍了匕首缺少与相同类型的数据存储区的绑定的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在我的项目中，我有两个DataStore(SharedPref更好的API)。我有AuthDataStore和UserDataStore，它们有不同的包。我想将这两个数据存储分别注入repositories。我用的是Dagger Hilt
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)
}
)
}
}
这是我的存储库。
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"
}
} }
以下是我的主要报告：
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。我读了很多关于刀柄的文档。但我对匕首缺乏了解。请帮帮我。
我的错误：

推荐答案
根据[Dagger/MissingBinding]行，Dagger正在寻找@Named("auth.chat.ds") AuthDataStore。这意味着您需要精确的绑定匹配，通常使用@Binds或@Provides提供，包括完全相同的类名、完全相同的泛型和完全相同的@Named注释(如@Named)。
但是，您的DataStoreModule列出：
@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provideAuthModule、@Named(value = Constants.AUTH_DS_NAME) ds: AuthDataStore中的参数不匹配。既不是@Named(AUTH_DS_NAME) DataStore<Preferences>，也不是未命名/不合格的AuthDataStore。
取下@Named，您就会好起来：
@Provides
@Singleton
fun provideAuthRepository(
api: AuthApiService,
/* @Named(value = Constants.AUTH_DS_NAME) */ ds: AuthDataStore,
/* ^-------------remove-----------------^ */
@Qualifier.Io io: CoroutineDispatcher
): AuthRepository
