SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps Java developers rapidly scaffold and understand enterprise-grade applications using Java 21 and Spring Boot 3.3, consolidating modern concurrency, data access, and security patterns into a reusable workflow.

Core Features & Use Cases

  • Java 21 LTS features: virtual threads, pattern matching, record patterns, and sealed classes for scalable concurrency.

  • Spring Boot 3.3 integration: REST controllers, services, repositories, WebFlux, and native support for modern dependencies.

  • JPA/Hibernate 7 patterns: entity mapping, relationships, transactions, and lazy/eager loading strategies.

  • Spring Security 6: JWT/OAuth2 integration and method-level security.

  • Testing readiness: JUnit 5 and TestContainers integration for end-to-end scenarios.

  • Build tools: Maven and Gradle configurations for Java 21.

  • Use Case: Build a microservice with a REST API, persistent data, and secure access, leveraging virtual threads for high concurrency.

Quick Start

Instruct the AI to scaffold a Spring Boot 3.3 project in Java 21, enable virtual threads, add JPA/Hibernate, and implement a simple REST endpoint secured with JWT.
