Spring Boot Tutorial
Learn Spring Boot step by step, from your first application to secure, tested and production-ready services. Simple explanations with practical Java examples for every topic.
- Auto-configuration
- Embedded Tomcat server
- REST APIs & Spring Data JPA
- Production-ready with Actuator
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.

- Managing settings with profiles and configuration properties
- Building, versioning and documenting REST APIs
- Handling exceptions and validating requests
- Working with databases using Spring Data JPA and Hibernate
- Transactions, pagination and database migrations
- Caching, scheduling, async processing and AOP
- Securing applications with Spring Security, JWT and OAuth2
- Testing and monitoring applications with Actuator
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.
