Mastering Spring Framework Fundamentals - Using Scopes with Java-based Configuration

The video tutorial discusses the concept of scopes in Java's Spring container, focusing on Singleton and prototype scopes. It explains how service instances behave when called multiple times and how to change the scope of beans using annotations. The tutorial also demonstrates debugging to observe instance creation and highlights the default Singleton scope of repositories.

What is the default behavior when a service is called multiple times in a Singleton scope?

• A new instance is created each time.

• The same instance is returned each time.

• The service is not available.

• An error is thrown.

How can you ensure a service always returns a new instance in Spring?

• By using a Prototype annotation.

• By using a Singleton annotation.

• By using a Default annotation.

• By using a Static annotation.

Which scope should be used if you want a new instance every time a bean is requested?

• Request

• Session

• Prototype

• Singleton

What happens to the repository bean when injected into prototype-scoped services?

• It becomes a prototype itself.

• It uses the same Singleton instance.

• It throws an error.

• It creates a new instance for each service.

What is the main focus of the final section of the video?

• Discussing the default scope of repository beans.

• Explaining Singleton scope in detail.

• Configuring database connections.

• Introducing new Spring features.
