Spring Modulith enforces module boundaries in a Spring Boot modular monolith by performing dependency checks and verifying architectural health through ApplicationModules analysis. This ensures structural integrity and prevents unauthorized cross-module dependencies.

A modular monolith architecture in Spring Boot structures a single application into logically separated modules to improve maintainability and scalability. Spring Modulith provides the guidelines and tools to design, review, and verify these module structures effectively.

To test module dependencies in a Spring Boot application, utilize Spring Modulith to execute module verification and write integration tests. This process checks architectural boundaries and validates that individual modules interact correctly without violating structural rules.

Yes, Spring Modulith works with Maven to generate architectural documentation and expose module information. It utilizes the Spring Boot actuator to provide observability and outputs structural diagrams of your application's module organization.

The best way to structure a Spring Boot application for maintainability is adopting a modular monolith design. Using Spring Modulith, you can organize code into ApplicationModules, verify boundaries, and generate documentation to ensure long-term architectural health.

You should reconsider a modular monolith approach if your application requires strict physical deployment isolation or distributed microservices. Spring Modulith focuses on logical boundaries within a single deployable unit, which may not suit highly distributed architectural contexts.
