What problem does it solve?

This skill helps developers build enterprise Java applications by leveraging Java 21 features and Spring Boot 3.3, providing structured guidance, practical patterns, and ready-to-use code examples to accelerate delivery and quality.

Core Features & Use Cases

  • Modern Java capabilities: Virtual Threads, Pattern Matching, and Record Patterns integrated with Spring Boot 3.3.
  • Spring ecosystem integration: REST controllers, JPA/Hibernate mappings, Spring Security configurations, and testing patterns for reliable services.
  • Use Case: Build a microservice with reactive APIs, structured concurrency, and secure data access, using a consistent code baseline.

Quick Start

  • Ensure you have a Java 21+ JDK installed and a compatible build tool (Maven or Gradle).
  • Create or clone a Spring-based project that uses Java 21 features and standard patterns, then run the build and start the app (e.g., mvn clean package && java -jar target/*.jar)
