在同一子组件内创建子组件特征

Question

使用 Dagger 我试图在同一个子组件中创建一个子组件（这意味着我想从功能 A 创建一个功能 A）。但是当我将这一行 fun plus(module: Module): BlogPostComponent 添加到我的子组件时，它会生成 StackOverflow 错误。

@BlogPostScope
@Subcomponent(modules = [BlogPostComponent.Module::class])
interface BlogPostComponent {

    fun plus(module: Module): BlogPostComponent

    @dagger.Module
    class Module {
        // Provide stuff
    }
}

@Scope
@kotlin.annotation.Retention(AnnotationRetention.RUNTIME)
annotation class BlogPostScope

知道如何解决这个问题吗？

这是错误堆栈跟踪：

Answer 1

我不相信这是可能的，部分原因是不清楚子 BlogPostComponent 将从父 BlogPostComponent 继承什么：根据定义，它具有相同的范围和 100% 的绑定重叠。

这将有助于了解：拥有这种无限的子组件层次结构的目标是什么？您希望继承哪些类型的绑定？ （会不会只是多重绑定？）

作为替代方案，您可以为您的 BlogPostComponent 提供一个 @Subcomponent.Builder ，而不是让 plus 返回子组件，您可以在其中传递父组件的实例（例如，@Nullable @Parent BlogPostComponent parent 使用您编写的 @Parent 限定符注释）。您将无法直接引用该父组件中的绑定，但您可以编写一个 @Provides 方法，该方法公开（例如）一个接受 @Parent BlogPostComponent 参数并从中返回 getBlogPostDirectory() 的 @Parent BlogPostDirectory。
