Spring Modulith Demo

This project demonstrates how to build a modular monolith using Spring Boot 3.5.5 and Spring Modulith. It features a clean separation of concerns with distinct modules (Product and Order) while maintaining a single deployable unit.

Prerequisites

• Java 17 or higher
• Gradle (included via wrapper)

Getting Started

Build the project

./gradlew build

Run the application

./gradlew bootRun

The application will start on http://localhost:8080

Run tests

./gradlew test

API Endpoints

• GET /api/products/hello - Product module greeting
• GET /api/orders/hello - Order module greeting

Modules

The application is organized into logical modules:

• Product Module: Handles product-related functionality
• Order Module: Handles order-related functionality

Each module is self-contained with its own controllers and services, demonstrating modulith boundaries.
