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.
