What it is

This is a repository of many small, separate Java tutorial projects, with a strong focus on the Spring Framework (Spring, Spring Boot and Spring Security). Each module covers one well-defined topic, so you can study or copy the one you need. The README also links to paid courses from Baeldung, the site that maintains the project.

  • Open one module in an IDE and read how a Spring Boot feature is implemented
  • Run a Spring Boot module with mvn spring-boot:run from its directory
  • Build a single module with mvn clean install inside its folder
  • Run unit or integration tests for one module using the profiles described in the README

Great for

  • Java developers who want to learn a specific Spring Boot or Spring Security topic
  • Students following along with Spring tutorial code
  • Developers who want a working example of a single Java feature to read or run
  • People comfortable with Maven who want to build individual modules

Not ideal for

  • Complete beginners to programming, since the README assumes Java and Maven knowledge
  • People looking for a single application to deploy, because this is a collection of separate examples rather than one product
  • Anyone needing non-Java examples, since the README focuses on the Java ecosystem

How to get it

  1. 1

    Clone and build from source

    You'll need: Git · Java (the README mentions JDK 8 through JDK 26 profiles; check the module for the version it needs) · Maven

    Clone the repository

    git clone https://github.com/eugenp/tutorials

    If cloning fails with a buffer error, increase the buffer size

    git config --global http.postBuffer 5000000

    Run a Spring Boot module from its directory

    mvn spring-boot:run
  2. 2

    Run it

    • Clone the repository with git clone.
    • Change into the directory of the module you want to study.
    • Run mvn clean install in that module directory to build it.
    • Run mvn spring-boot:run in the module directory if it is a Spring Boot app.
  3. 3

    Get the most out of it

    • Import only the module you need into Eclipse or IntelliJ instead of the whole repository
    • Use mvn clean install -Pparents to build parent modules before a child module that depends on them
    • Run unit tests with mvn clean install and integration tests with the -Pintegration profile
    • Use --pl with -Pdefault to build a chosen set of modules from the root

Strengths

  • Covers many specific Spring and Java topics in separate, focused modules
  • Modules can be built and run independently, so you do not need the whole repository
  • The README documents the Maven profiles and build commands clearly

Trade-offs

  • The repository is very large, and the README says building everything at once is rarely needed
  • Some modules depend on parent modules that must be built first
  • The README is truncated here and does not describe each module's content, so you must browse the folders yourself
