SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the slow, error-prone setup of modern Java service projects by providing a consistent structure and baseline configuration for frameworks like Spring Boot, Quarkus, or Micronaut.

Core Features & Use Cases

  • Framework-ready project structure: organizes code into clear layers (web, message, domain, infrastructure, core) to support long-term maintainability.
  • Modern Java best practices: recommends records, sealed interfaces, pattern matching, and (when applicable) virtual threads and structured concurrency patterns.
  • Production-minded configuration & conventions: includes essential settings such as spring.jpa.open-in-view: false, graceful shutdown, actuator/health exposure, and sensible Jackson defaults.
  • Quality-focused testing guidance: suggests JUnit 5, AssertJ, Testcontainers, and ArchUnit to validate architecture boundaries.
  • Use case example: when starting an order-processing API, apply the structure and configuration so controllers, domain logic, persistence, and messaging are separated and testable from day one.

Quick Start

Use the java-project-setup skill to create a new Java 21+ service scaffold using the recommended package structure, production-ready configuration conventions, and the suggested testing approach.

FAQPage Schema
How do I scaffold a new Java project with Spring Boot, Quarkus, or Micronaut?

To scaffold a Java service, apply a baseline package structure separating web, domain, and infrastructure layers, then configure JPA, health endpoints, and global exception handling for your chosen framework.

What is the best way to structure a Java service for long-term maintainability?

The best way to structure a Java service is organizing code into clear architectural boundaries like web, message, domain, infrastructure, and core layers to enforce separation and support long-term maintainability.

How do I configure production-ready settings for a Java REST API?

Configure production-ready Java APIs by disabling spring.jpa.open-in-view, enabling graceful shutdown, exposing actuator/health endpoints, and applying sensible Jackson defaults for reliable service operation.

Does this Java project setup support modern Java features like records and sealed types?

Yes, the Java project setup supports modern features by recommending records, sealed interfaces, pattern matching, and virtual threads with structured concurrency patterns for Java 21+ services.

How do I test architecture boundaries and messaging integrations in a Java project?

Test architecture boundaries and messaging integrations using JUnit 5, AssertJ, Testcontainers, and ArchUnit to validate package structure and plan tests for REST/HTTP plus messaging integrations.

Can I use this scaffolding approach for an order-processing API with messaging?

Yes, you can use this scaffolding approach for an order-processing API to separate controllers, domain logic, persistence, and messaging, ensuring they remain isolated and testable from day one.
