Spring @Lookup Annotation | How to Inject Prototype Bean into Singleton Bean Correctly
Java Spring Boot Interview Q20 !!
In this video, we explore how @Lookup annotation solves a common issue in Spring Boot— when a Prototype-scoped bean is injected into a Singleton bean, it starts behaving like a Singleton.
You'll learn:
1) Why prototype inside singleton breaks expected behaviour
2) How @Lookup uses lookup method injection to fix it
3) Differences between singleton vs prototype scope
4) How to properly use @Scope, @Lookup, and Spring’s dependency injection model
Perfect for understanding bean scopes in Spring and how to manage singleton-prototype dependencies correctly.
