让我们假设我有基于相同类X的bean A和B.是否可以将@Component注释应用于类X，并使Spring仍能分别识别它们？Spring - multiple @Components

不，这是不可能的，因为Spring注释@Component不是可继承的注释。

否... java语言不支持继承对子类的注释。 –
它实际上是这样做的，但注解需要用'@ Inherited'标记，请参阅https://docs.oracle.com/javase/7/docs/api/java/lang/annotation/Inherited.html。然而，Spring注解'@ Component'不是这样注释的。 – john16384
Doh。你是对的，我混淆了混音界面。但实际上，组件的Spring注释使用'@ Inherited'注释，因此也不起作用。 –
