Spring Boot is one of the most widely used frameworks for building Java-based web applications and microservices. Many companies ask Spring Boot related questions during backend developer interviews.
Spring Boot is a framework that simplifies the development of Spring applications by providing auto-configuration, embedded servers, and production-ready features.
Auto configuration automatically configures Spring components based on the dependencies available in the project. This reduces the need for manual configuration.
Starters are dependency bundles that simplify dependency management. For example:
Spring Boot Actuator provides monitoring and management features for production applications. It includes endpoints for health checks, metrics, and application information.
Dependency Injection is a design pattern used by Spring to automatically provide objects required by a class instead of creating them manually.
Understanding Spring Boot fundamentals is essential for backend developers. Practicing common interview questions and building projects using Spring Boot will significantly improve your interview performance.
