Building Modular Monoliths using Spring Modulith
summary
Builds a runnable Spring Boot monolith with Spring Modulith enforcing module rules via a JUnit modularity test that fails on non‑exposed types and circular dependencies, demonstrates event durability with an event outbox persistence table (optional RabbitMQ fan‑out), auto‑generated C4/PlantUML diagrams and Zipkin-style traces, and a migration path: refactor to package‑by‑feature, mark modules open selectively, separate schemas per module. Demo code and tests run and show violations when rules are broken and pass after fixes.
