没有名称引用的 koin 默认实现
koin default implementation without name reference
我有 2 个 Retrofit 客户端,其中一个是默认的,第二个有不同的实现,例如(基础 URL、拦截器等...)
我需要在不使用名称引用的情况下注入默认客户端
第一个客户:-
single<Retrofit> {
Retrofit.Builder()
.baseUrl(RemoteConstants.BASE_URL)
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(APIResponseConverter())
.addConverterFactory(GsonConverterFactory.create(get()))
.client(get())
.build()
}
第二个客户:-
single<Retrofit>("retrofit_second") {
Retrofit.Builder()
.baseUrl("diffrent url")
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create(get()))
.client(get("SecondOkHttpClient"))
.build()
}
我的注射方式
val myModule = module {
factory { get<Retrofit>().create(FirstAPI::class.java) } // Why Koin did not figure it without providing its default name !?
factory { get<Retrofit>("retrofit_second").create(SecondAPI::class.java) }
factory<IMyRemoteDataSource> { MyRemoteDataSource(get(), get()) }
factory<IMyRepository> { MyRepository(get()) }
factory { MyUseCase(get()) }
}
结果是:
Multiple definitions found for type 'class retrofit2.Retrofit' - Koin can't choose between :
Single [name='retrofit_second',class='retrofit2.Retrofit']
Single [name='Retrofit',class='retrofit2.Retrofit']
为什么 Koin 在没有提供默认名称(Retrofit)的情况下没有获得默认的 Retrofit 实例!?
factory { get<Retrofit>().create(FirstAPI::class.java) }
你是对的@Eslam。当前行为(从 koin:1.0.2
开始)是当您未指定依赖项名称时,它是 treated as an empty string. And then the definitions get filtered by class name:
fun searchByClass(clazz: KClass<*>): List<BeanDefinition<*>> {
return definitions.filter { clazz in it.classes }
}
结果你得到了你的两个定义,这导致了上面提到的错误:Multiple definitions for class ...
