1. What is Spring Boot?

Spring Boot is a Java framework that simplifies the development of Java applications by providing default configurations, dependency management, and production-ready features out of the box.

2. Explain the key features of Spring Boot.

• Auto-configuration: Spring Boot automatically configures application components based on classpath settings and dependencies.
• Starter dependencies: Spring Boot provides a set of curated dependencies that are commonly used together for specific functionalities.
• Embedded server: Spring Boot comes with an embedded server (e.g., Tomcat, Jetty) that eliminates the need for deploying applications to a separate server.
• Actuator: It provides production-ready features like health checks, metrics, and monitoring for applications.
• Spring Boot CLI: Spring Boot Command Line Interface allows rapid prototyping and development using Groovy scripts.

3. How does Spring Boot differ from the Spring Framework?

Spring Boot builds on top of the Spring Framework and aims to simplify the configuration and setup process.
