无法使用 @WorkerInject 在 WorkManager 中注入 @Binds Hilt 依赖项

Question

我尝试使用以下代码构建

遵循 Hilt-WorkManager 官方文档

工人class

class StartJobWorker @WorkerInject constructor(
    @Assisted appContext: Context,
    @Assisted workerParams: WorkerParameters,
    private val startJobUseCase: StartJobUseCase,
) : CoroutineWorker(appContext, workerParams) {

    override suspend fun doWork(): Result {
        val jobId: Long = inputData.getLong(AppConstant.JOB_ID, 0)
        return when (val workResult: WorkResult = startJobUseCase(jobId)) {
            is WorkResult.Success<*> -> Result.success()
            is WorkResult.Failure<*> -> Result.failure()
            WorkResult.Retry -> Result.retry()
        }
    }

}

刀柄模块

@Module
@InstallIn(ActivityComponent::class)
abstract class UseCaseModule {

    @ActivityScoped
    @Binds
    abstract fun bindStartJobUseCase(startJobUseCaseImpl: StartJobUseCaseImpl): StartJobUseCase

}

依赖抽象

interface StartJobUseCase {
    suspend operator fun invoke(jobId: Long): WorkResult
}

依赖实现

class StartJobUseCaseImpl @Inject constructor(
    private val startJobRepository: StartJobRepository
) : StartJobUseCase {

    override suspend fun invoke(jobId: Long): WorkResult {
        return startJobRepository.startJob(jobId)
    }

}

我在编译中收到以下错误消息。

error: [Dagger/MissingBinding] com.example.domain.StartJobUseCase cannot be provided without an @Provides-annotated method.

请让我知道这个问题的解决方案。

Answer 1

正如 EpicPandaForce 所说，用 ApplicationComponent 交换 ActivityComponent 并删除 UseCaseModule class 中的 @ActivityScoped 解决了这个问题。

刀柄模块

@Module
@InstallIn(ActivityComponent::class)
abstract class UseCaseModule {

    @Binds
    abstract fun bindStartJobUseCase(startJobUseCaseImpl: StartJobUseCaseImpl): StartJobUseCase

}
