Spring Boot Bootstrap

Create runnable Spring Boot applications with controllers, services, configuration, validation, health checks, and tests.

Purpose

Help AI coding tools generate a coherent Spring Boot starting point that builds, tests, and exposes a small REST API with production-minded defaults.

Current status

Available on Grok.
Planned for GitHub Copilot and Claude Code.

Supported frameworks

Spring Boot

Supported Java versions

Java 21 (preferred)
Java 17 (supported)

Supported platform repositories

Platform	Repository	Status
Grok	java-for-grok	Available
GitHub Copilot	java-for-github-copilot	Planned
Claude Code	java-for-claude-code	Planned

Common use cases

Greenfield REST API bootstrap
Layered controller / service / repository structure
Validation and problem details for invalid input
Actuator health endpoints
Adding persistence, Testcontainers, and configuration properties iteratively

Example prompts

Bootstrap a Spring Boot application using Java 21 and Maven.

Create a customer REST API with controller, service, repository, validation, Actuator, and tests.

Add PostgreSQL persistence and Testcontainers to this Spring Boot project.

Add centralized exception handling to this Spring Boot REST API.

Add type-safe configuration using @ConfigurationProperties.

Limitations

Does not replace Spring Security hardening; see the security guide.
Persistence choices should be stated in the prompt; defaults stay intentionally small.
Platform packaging outside Grok may lag the skill content on this site.

Roadmap

Copilot and Claude Code packaging
Optional modules for security, observability, and modernization
Broader example coverage beyond a single REST resource
