我如何使用 Kodein 的直接检索来获取作为工厂的依赖绑定？

Question

考虑以下注入器：

class Injector constructor(secretSauce: SecretSauce) {
    val kodein = Kodein {
        bind<SpicyBeans>() with factory { beans: List<Bean>, herbs: List<Herb> ->
            SpicyBeans(secretSauce, beans, herbs)
        }
    }
}

以及以下业务逻辑：

class TastyMeal {
  private lateinit var injector : Kodein
  private lateinit var spicyBeans : SpicyBeans

  fun initialiseWithInjector(kodein : Kodein) {
    injector = kodein
    val herbs = listOf(Coriander(), Cumin())
    val beans = listOf(Pinto(), BlackEyed())
    // fetch SpicyBeans via given Kodein Factory, given herbs and beans here
  }
}

如何使用 Kodein 的直接注入功能通过工厂获取 SpicyBeans 实例，传入 List<Herb> 和 List<Bean> after TastyMeal 是否实例化？我在文档中找不到示例。

Answer 1

尝试这样的事情：

class Injector constructor(secretSauce: SecretSauce) {
    val kodein = Kodein {
        bind<SecretSauce> with instance(secretSauce)
        bind<SpicyBeans>() with factory { beans: List<Bean>, herbs: List<Herb> 
->
        SpicyBeans(instance(), beans, herbs)
       }
    }
}

然后：

val spicyBeans by kodein.newInstance { SpicyBeans(instance(), beans, herbs) }

Answer 2

解决方案称为 multi-argument 工厂。这方面的文档非常稀少（这是个问题，能不能开个工单提醒我完善文档？）。

同时，这是您的解决方案：

val tastyDish: SpicyBeans by kodein.instance(arg = M(beans, herbs))
