Mastering Spring Framework Fundamentals - Understanding the Prototype Scope

The video tutorial explains the concept of scopes in the Spring framework, focusing on Singleton and Prototype scopes. It describes how Singleton scope ensures a single instance of a bean, while Prototype scope creates a new instance each time. The tutorial also covers the Request scope for web applications and highlights considerations like thread safety and resource management. Finally, it demonstrates how to explicitly declare a scope in the Spring configuration.

What is the default scope of a bean in Spring?

• Request

• Prototype

• Session

• Singleton

What happens when a bean is defined with Prototype scope?

• The bean is created once per HTTP request

• A single instance is shared across the application

• A new instance is created each time it is requested

• The bean is created once per session

How can you explicitly define a Singleton scope in Spring XML configuration?

• By setting the scope attribute to 'session'

• By setting the scope attribute to 'prototype'

• By setting the scope attribute to 'singleton'

• By setting the scope attribute to 'request'

What is a key consideration when using Prototype scope in a loop?

• It simplifies garbage collection

• It ensures thread safety

• It can lead to excessive resource consumption

• It reduces memory usage

What is the lifetime of a Request scoped bean in a web application?

• Each HTTP request

• The entire application context

• Each server restart

• Each user session
