SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Organize Spring Boot code into explicit application modules with enforceable boundaries, publishable module events, and dedicated module-focused tests to improve maintainability and reduce architectural drift.

Core Features & Use Cases

  • Enforce module boundaries using explicit named interfaces to prevent leakage of internal packages.
  • Publish and react to cross-module events to coordinate interactions between modules.
  • Provide scenario- and boundary-focused tests to validate architecture in CI.

Quick Start

Create a Spring Boot project and apply the Modulith boundaries to structure modules, enable module events, and add boundary tests.

FAQPage Schema
How do I structure a Spring Boot application into explicit modules?

You can structure a Spring Boot application into explicit modules by defining modular boundaries, enforcing named interfaces to prevent internal package leakage, and publishing cross-module events to coordinate interactions safely.

What is the best way to prevent internal package leakage in a Spring Boot monolith?

The best way to prevent internal package leakage in a Spring Boot monolith is to enforce module boundaries using explicit named interfaces, which restricts direct access to internal packages and reduces architectural drift.

How do I verify module boundaries in a Spring Boot application?

You verify module boundaries in a Spring Boot application by running boundary verification tests using ApplicationModules.verify() and scaffolding dedicated module-focused tests with @ApplicationModuleTest in your CI pipeline.

Can I use event-driven communication between modules in a Spring Boot monolith?

Yes, you can use event-driven communication in a Spring Boot monolith by publishing and reacting to cross-module events, allowing isolated modules to coordinate interactions without direct dependencies.

Does Spring Modulith require a specific Spring Boot version to set up module boundaries?

Spring Modulith requires an existing Spring Boot project and recommends applying a specific Spring Modulith BOM version to structure modules, enable events, and add boundary tests successfully.
