Final answer:
Spring Boot streamlines Java application development with automatic configuration, convention-over-configuration, and built-in features for common tasks.
Step-by-step explanation:
Spring Boot is a framework that simplifies the development of Java-based applications. It leverages the Spring Framework and provides additional tools and libraries to streamline the process. Internally, a Spring Boot application works by using annotations and conventions to auto-configure various components and dependencies. It follows a convention-over-configuration approach which allows developers to focus on writing business logic without worrying too much about the underlying infrastructure.
When a Spring Boot application is launched, it starts by scanning the classpath for Spring components and building an application context. This context contains all the necessary beans and dependencies required by the application. It also initializes the embedded server to handle incoming HTTP requests.
Once the application is up and running, Spring Boot provides several features like auto-configuration, dependency injection, and aspect-oriented programming to enhance the functionality of the application. It simplifies the setup of common components like database connections, logging, and security by providing default configurations that can be easily customized.
