无法将dao依赖项传递给android工作管理器构造函数
无法将dao依赖项传递给android工作管理器构造函数
提问于 2022-09-06 10:59:25
我遇到了工作经理的问题。我想将一个dao传递给工作管理器构造函数，并遵循所有的实现，但是无法访问这个dao。
java.lang.NoSuchMethodException: com.itmedicus.pdmderma.worker.DermaWorker.android.content.Context类，androidx.work.WorkerParameters类

@HiltWorker
class DermaWorker @AssistedInject constructor(
@Assisted appContext: Context,
@Assisted params: WorkerParameters,
private val dermaDao: DermaDao
): CoroutineWorker ( appContext,params)
{
override suspend fun doWork(): Result = withContext(Dispatchers.IO) {
try {
DamiData.addDermaList()
val list = DamiData.dermaList
for (derma in list) {
dermaDao.insertDermaContent(derma)
}
Result.success()
} catch (ex: Exception) {
Result.failure()
}
}
}应用类
@HiltAndroidApp
class PdmDerma : Application(), Configuration.Provider {
@Inject
lateinit var workerFactory: HiltWorkerFactory
companion object {
lateinit var appContext: Context
}
override fun onCreate() {
super.onCreate()
appContext = applicationContext
plant(Timber.DebugTree())
}
override fun getWorkManagerConfiguration(): Configuration {
return Configuration.Builder().setWorkerFactory(workerFactory)
.setMinimumLoggingLevel(android.util.Log.DEBUG)
.build()
}

是的我解决了这个问题。我试图从一个viewmodel.In (视图模型构造函数)中插入工作管理器，在这个过程中，我传递的是私有val workmanager : WorkManager.But，在这个过程中，我不能插入我为上下文保留的AndroidViewModel &手动创建工作管理器依赖项。这是我的解题代码。
@HiltViewModel
class DermaViewModel @Inject constructor(
private val dermaRepository: DermaRepository,
application
) : AndroidViewModel(context) {
init {
initWorkManager()
}
private fun initWorkManager() {
val request: WorkRequest = OneTimeWorkRequestBuilder<DermaWorker>()
.build()
val workManager = WorkManager.getInstance(context)
workManager.enqueue(request)
}
