Spring Boot DevOps Sample

A lightweight Spring Boot application demonstrating a simple REST service with basic health/version endpoints and a ready-to-use Maven-based DevOps setup.

Project Summary

This repository contains a minimal Spring Boot service built with Java 21 and Maven. It is designed to showcase:

• Spring Boot web application structure
• REST controller with health check and version endpoints
• Maven build lifecycle with wrapper support
• CI/CD pipeline readiness via Jenkinsfile

Why this project matters for recruiters

This repository is a good fit for evaluating:

• Java and Spring Boot fundamentals
• Maven project configuration and build tooling
• REST API implementation and controller design
• DevOps readiness through Jenkins pipeline integration
• Ability to maintain a small, clean, production-style repository

Key Features

• GET / — returns a simple welcome message
• GET /health — returns application health status (UP)
• GET /version — returns the service version (1.0.0)

Technology Stack

• Java 21
• Spring Boot 4.1
• Spring Web
• Maven
• Lombok (compile-time / optional)
• Jenkins pipeline integration with Jenkinsfile

Repository Structure

• src/main/java/com/example/spring_boot_devops/ — main application classes
• src/main/java/com/example/spring_boot_devops/controller/ — REST controllers
• src/test/java/com/example/spring_boot_devops/ — unit tests
• pom.xml — Maven build and dependency configuration
• mvnw, mvnw.cmd — Maven wrapper for consistent builds
• Jenkinsfile — pipeline configuration for continuous delivery

Setup and Run Locally

Prerequisites

• Java 21
• Git

Build and run

./mvnw clean package
./mvnw spring-boot:run

The application starts on port 8080 by default.

Verify endpoints

curl http://localhost:8080/
curl http://localhost:8080/health
curl http://localhost:8080/version

Testing

Run the test suite with:

./mvnw test
