我有一个包含3个不同模块的应用：app(main)，api和repository
我的app模块依赖于repository模块，而依赖于api模块：
app -(depends)-> repository -(depends)-> api
我想在所有3个模块中使用Dagger2相互注入依赖关系，而不必将这些依赖关系暴露给不需要查看的模块。
基本上，api模块将提供与服务相关的类以与API通信
repository模块将使用api类来协调资源的调用
app模块将仅直接使用repository类，而无需了解api模块的任何内容
以下是我的匕首模块/组件的结构：
ApiModule：
@Component(modules = [ApiModule::class])
interface ApiComponent {
@Component.Builder
interface Builder {
@BindsInstance
fun requestApiModule(apiModule: ApiModule): Builder
fun build(): ApiComponent
}
}
@Module
class ApiModule {
@Provides
@Reusable
fun provideApiClient(apiConfig: ApiConfig) = ApiClient(apiConfig)
@Provides
@Reusable
fun provideConsumerService(appConsumerService: AppConsumerService): ConsumerService = appConsumerService
@Provides
@Reusable
fun provideParkingService(appParkingService: AppParkingService): ParkingService = appParkingService
}
RepositoryModule：
@Component(
modules = [RepositoryModule::class],
dependencies = [ApiComponent::class]
)
interface RepositoryComponent {
@Component.Builder
interface Builder {
@BindsInstance
fun requestRepositoryModule(repositoryModule: RepositoryModule): Builder
fun apiComponent(apiComponent: ApiComponent): Builder
fun build(): RepositoryComponent
}
}
@Module
class RepositoryModule {
@Provides
@Reusable
fun provideLocalStorage(application: Application) = LocalStorage(application.applicationContext)
@Provides
@Reusable
fun provideLocalSession(application: Application) = LocalSession(application.applicationContext)
@Provides
@Reusable
fun provideApiConfig(apiRepositoryConfig: ApiRepositoryConfig): ApiConfig = apiRepositoryConfig
@Provides
@Reusable
fun provideConsumerRepository(appConsumerRepository: AppConsumerRepository): ConsumerRepository =
appConsumerRepository
@Provides
@Reusable
fun provideParkingRepository(appParkingRepository: AppParkingRepository): ParkingRepository = appParkingRepository
}
AppModule：
@Singleton
@Component(
modules = [ActivityModule::class, ViewModelModule::class, AndroidInjectionModule::class],
dependencies = [RepositoryComponent::class]
)
interface ApplicationComponent : AndroidInjector<CustomApplication> {
override fun inject(customApplication: CustomApplication)
@Component.Builder
interface Builder {
@BindsInstance
fun application(application: Application): Builder
fun repositoryComponent(repositoryComponent: RepositoryComponent): Builder
fun build(): ApplicationComponent
}
}
尝试运行项目后，我在生成输出中看到当前错误
