Spring Boot Tutorials

Spring Boot Tutorials contains various tutorials for various Spring projects such as Spring Boot, Spring Security, Spring Data, Spring Batch, Spring Cloud, Spring Security, Spring GraphQL, and Spring Modulith. Each tutorial comes with source code in individual submodules and can be found on GitHub.

Motivation

These tutorials are created with testing and best practices in mind, inspired by daily work and questions from the community. The goal is to provide a reference for developers to learn and apply in their projects. I have chosen not to use mock frameworks in tests, opting instead to write integration tests with actual databases and services. This is, and always will be, my primary goal.

With the help of Dependabot, each tutorial is also kept up-to-date with the latest dependencies. Currently, we are using Java Temurin 25 with Spring Boot 4.1.1.

Documentation

All tutorials are documented in AsciiDoc format and published as an Antora site at rashidi.github.io/spring-boot-tutorials.
