What is Spring Framework?

Spring Framework is a popular open-source Java-based application framework that provides a comprehensive infrastructure for developing Java applications. It was initially created to simplify the development of enterprise applications, but it has since expanded to become a general-purpose framework for developing any kind of Java application.

What is Spring Boot?

Spring Boot is basically an extension of the Spring framework which eliminated the boilerplate configurations required for setting up a Spring application.

Spring Boot is an opinionated framework that helps developers build Spring-based applications quickly and easily. The main goal of Spring Boot is to quickly create Spring-based applications without requiring developers to write the same boilerplate configuration again and again.

Tools and technologies used:

– Spring Boot 3

– Java 17 or later

– IntelliJ IDEA

– Maven

– Postman
