错误：找不到符号@dagger.hilt.InstallIn(value={ApplicationComponent.class})

html5 • • 问答

升级匕首柄后（版本：2.31-alpha）ApplicationComponent.class无法找到。Component类似 RoomDatabase的替代方案是什么？

@Module
@InstallIn(ApplicationComponent::class)
class RoomModule() {
private val DATABASE_NAME = "salat_time"

@Singleton
@Provides
fun provideRoomDatabase(@ApplicationContext appContext: Context) = Room.databaseBuilder(
    appContext,
    AppDatabase::class.java,
    DATABASE_NAME
).createFromAsset("db/$DATABASE_NAME.sqlite").build()

@Singleton
@Provides
fun provideLocalSalatRepository(database: AppDatabase) = LocalSalatRepository(database)

@Singleton
@Provides
fun provideDistrictRepository(database: AppDatabase) = DistrictRepository(database)
}

回答

ApplicationComponent在 Dagger 版本2.30 中 已弃用，
ApplicationComponent在 Dagger 版本2.31 中 删除
或者SingletonComponent应该使用代替ApplicationComponent

@Module
@InstallIn(SingletonComponent::class)
class RoomModule() {
   . . .
}

  • **Note:** For those who are still unable to find `SingletonComponent` while importing, it is in `dagger.hilt.components.SingletonComponent` package. All other `Components` are in `dagger.hilt.android.components` package.

回答

ApplicationComponent更名为SingletonComponent

以上是错误：找不到符号@dagger.hilt.InstallIn(value={ApplicationComponent.class})的全部内容。
THE END
