SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Setting up a new Spring Boot backend from scratch involves many manual decisions: picking dependencies, configuring the database connection, adding API documentation, and wiring up Docker. This Skill automates the entire scaffolding process so the team gets a consistent, buildable Java 21 project aligned with the kit's fixed technology stack. ## Core Features & Use Cases - Project Generation via start.spring.io: Downloads a Maven + Java 21 + Spring Boot 3.3 starter with the kit's dependency set (web, data-jpa, postgresql, validation, testcontainers, lombok). - API Docs and Architecture Testing: Adds springdoc-openapi for Swagger UI and ArchUnit for architecture rule tests. - PostgreSQL 16 with Docker Compose: Creates a compose.yaml with a single PostgreSQL 16 service and configures the datasource to read the password from the POSTGRES_PASSWORD environment variable, never hardcoded. - Use Case: At the start of a modernization sprint, ask the assistant to create the backend module; it downloads the starter, configures JPA with ddl-auto=validate for Flyway-controlled migrations, and verifies the build with ./mvnw clean test. ## Quick Start Ask the assistant to create a new Spring Boot 3.3 Java 21 project named backend with PostgreSQL and Docker Compose support.

Frequently Asked Questions about create-spring-boot-java-project

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a Spring Boot project with Java 21 and Maven?▼

Download a starter from start.spring.io with type=maven-project, javaVersion=21, and bootVersion=3.3.5, then unzip it into your target directory. This Skill automates that curl request with the kit's dependency set and verifies the result with ./mvnw clean test.

How to add springdoc-openapi and ArchUnit to a Spring Boot project?▼

Add springdoc-openapi-starter-webmvc-ui version 2.8.6 as a compile dependency and archunit-junit5 version 1.2.1 with test scope to the pom.xml. SpringDoc then exposes a Swagger UI, and ArchUnit runs architecture rules during tests.

Can I use Redis or MongoDB with this Spring Boot setup?▼

No. The kit's technology stack is fixed to PostgreSQL 16 only, with no Redis, MongoDB, or cache starter dependencies. The generated compose.yaml defines a single PostgreSQL 16 service.

How do I configure the PostgreSQL password without hardcoding it?▼

Reference ${POSTGRES_PASSWORD} in application.properties and compose.yaml, then define the variable in your terminal or a Git-ignored .env file. Never commit credentials to the repository or hardcode them in configuration files.

Why use ddl-auto=validate instead of update in Spring JPA?▼

The validate setting makes Hibernate only check the schema against entities instead of modifying it. Versioned Flyway migrations control the schema, preventing accidental uncontrolled changes to the database structure.
