带有泛型接口的Dagger/DuplicateBindings，即使在使用限定符注释时也是如此 &g

Question

我有一个这样定义的基本接口:

@JvmSuppressWildcards
abstract class IWorkerContract<T, R>(
private val mContext: Context,
// Some other stuff
) {
private val ctx: CoroutineScope = CoroutineScope(Job())
// Some other stuff
}

现在，我有两个类来实现这个接口

class ShopItemProductDescWorkerContract @Inject constructor(
// Some other stuff
) : IWorkerContract<@JvmSuppressWildcards List<ShopItemDescription>,@JvmSuppressWildcards String>( // important part
// Some other stuff
){
class ShopItemTechnicalDescWorkerContract @Inject constructor(
// Some other stuff
) : IWorkerContract<@JvmSuppressWildcards List<ShopItemDescription>,@JvmSuppressWildcards String>(
// Some other stuff
){

最后，在我的模块

@Module
@InstallIn(ViewModelComponent::class)
abstract class WorkerModule {
@WorkerContract(EWorkerContracts.SHOP_ITEM_PROD)
@Binds
abstract fun bindShopItemProductDescWorkContract(sipContract: ShopItemProductDescWorkerContract): IWorkerContract<List<ShopItemDescription>, String>
@WorkerContract(EWorkerContracts.SHOP_ITEM_TECH)
@Binds
abstract fun bindShopItemTechnicalDescWorkContract(sitContract: ShopItemTechnicalDescWorkerContract): IWorkerContract<List<ShopItemDescription>, String>
}
@Retention(AnnotationRetention.RUNTIME)
annotation class WorkerContract(val value: EWorkerContracts)
enum class EWorkerContracts {
SHOP_ITEM_PROD,
SHOP_ITEM_TECH
}

错误

Answer 1

在示例中没有使用@Named，而是使用@WorkerContract作为限定符注释。(@Named是内置的限定符注释，但您可以创建自己的，如在您的示例中。)

但是，您错过了@Qualifier元注释本身:

标识限定符注释。任何人都可以定义新的限定符。限定符注释:

• 有@Qualifier、@Retention(RUNTIME)和@Documented注释。
• […]

由于@Documented是可选的，并且只影响Javadoc，所以请确保添加@Qualifier，这样就可以了。

@Qualifier
@Retention(AnnotationRetention.RUNTIME)
annotation class WorkerContract(val value: EWorkerContracts)
