Key Concepts in Spring Boot for Interviews

1. Introduction to Spring Boot

Interview Question Example:
“What is Spring Boot, and how does it differ from the Spring Framework?”

Explanation:
Spring Boot is an extension of the Spring Framework, designed to simplify the process of setting up and developing applications. Unlike the core Spring Framework, which requires complex configuration, Spring Boot is opinionated, meaning it makes assumptions about the configuration by default. Spring Boot provides out-of-the-box support for embedded servers, production-ready metrics, and simplified dependency management.
