Spring Boot Project Creator
Overview
Generates a fully configured Spring Boot project from scratch using the Spring Initializr API. The skill walks the user through selecting project parameters, choosing an architecture style (DDD or Layered), configuring data stores, and setting up Docker Compose for local development. The result is a build-ready project with standardized structure, dependency management, and configuration.
When to Use
Bootstrap a new Spring Boot 3.x or 4.x project with a standard structure.
Initialize a backend microservice with JPA, SpringDoc OpenAPI, and Docker Compose.
Scaffold a project following either DDD (Domain-Driven Design) or Layered (Controller/Service/Repository/Model) architecture.
Set up local development infrastructure with PostgreSQL, Redis, and/or MongoDB via Docker Compose.
Trigger phrases: "create spring boot project", "new spring boot app", "bootstrap java project", "scaffold spring boot microservice", "initialize spring boot backend", "generate spring boot project".
Prerequisites
Before starting, ensure the following tools are installed:
Java Development Kit (JDK): Version 17+ (Java 21 recommended for Spring Boot 3.x/4.x)
