What is Spring Boot?

Spring Boot is an open-source framework that simplifies the development of Java applications. It is built on top of the Spring Framework and aims to make it easy to create production-ready, stand-alone Spring-based applications.

Why Spring Boot?

Spring Boot provides several benefits for Java developers:

  • Streamlined setup and configuration
  • Integrated support for various data sources
  • Embedded web server options (Tomcat, Jetty, etc.)
  • Production-ready features like metrics, health checks, and security

Sample Code

Let's take a look at a simple Spring Boot application:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
public class MySpringBootApplication {
public static void main(String[] args) {
SpringApplication.run(MySpringBootApplication.class, args);

This is a basic Spring Boot application with a main class annotated as @SpringBootApplication. It's enough to start a Spring Boot application.

Getting Started

To get started with Spring Boot, follow these steps:

  1. Install Spring Boot CLI or set up your development environment.
  2. Create a Spring Boot project.
  3. Write your application code and run it.


Spring Boot is a powerful framework for building modern Java applications. It simplifies the development process and provides a wide range of features to create robust, production-ready software.
