What Is Spring Boot?

Spring Boot is a framework built on top of the Spring Framework that makes it quick to create stand-alone Java applications. It configures common features for you, packages a web server inside your application, and lets you start a project with a few dependencies instead of long XML or Java configuration.

Who this is for

Java developers new to Spring, backend engineers building web services and microservices, and anyone preparing for Spring Boot interviews.

Prerequisites

Core Java and OOP, basic HTTP and REST concepts, simple SQL, and some experience with Maven or Gradle.

How a Spring Boot Application Works

A request reaches the embedded server inside your application. A controller receives it, a service applies the business rules, and a repository reads or writes the data. Spring Boot wires these layers together and connects them to databases, message brokers and monitoring tools.

Why Learn Spring Boot?

Rapid Development

Starters and auto-configuration remove most setup work, so you can focus on business logic.

Industry Standard

Spring Boot is one of the most widely used Java frameworks, so the skill is in demand for backend roles.

Microservices Ready

Small, self-contained applications are easy to build, deploy and scale independently.

Production Ready

Health checks, metrics and externalized configuration are available from day one.

Microservices Design and build distributed systems with Spring Boot services. Apache Kafka Stream events between Spring Boot applications. System Design Scalability, caching and load balancing for large applications.
