Why Spring Boot?

• Aim: Remove the fear of Spring Boot.
• Spring Boot simplifies creating standalone, production-grade Spring-based applications.
• Helps in easy creation of Spring applications by reducing boilerplate code and manual configuration.
• Provides auto-configuration and an embedded server to simplify deployment.

Key Points

• Spring Boot Definition: A framework for building Java applications.
• Ease of Use: Spring Boot simplifies the creation of Spring applications by reducing configuration efforts.
• Historical Context: Earlier, Spring required a lot of manual configuration. Spring Boot eliminates this need.
• Standalone Applications: No need for an external Tomcat server as Spring Boot comes with an embedded server.

Features of Spring Boot

• Auto-Configuration: Automatically configures Spring application based on the added dependencies.
• Embedded Server: Contains an embedded Tomcat server, making the application self-contained.
• Annotations: Uses annotations like @SpringBootApplication to simplify configuration.
• Application Context: Manages beans (objects) and provides them when required without repetitive instantiation.
