5. Ivan Garcia Sainz-Aja @ivangsa About Me Programming with Springframework since 2004
6. Complex Systems from Simple Components Event-Driven Architectures
7. Complex Systems from Simple Components Software Design: Evolutionary, Separation of Concerns Performant, Non-Blocking, Eventual Reliable and Consistent
8. Complex Systems from Simple Components Software Design: Evolutionary, Separation of Concerns Performant, Non-Blocking, Eventual Reliable and Consistent
9. Clinical Tool - Use Case

19. Event-Driven Spring Modulith Async Event Handlers
20. Spring Event Listener
21. Decoupling Modules with Events
22. Complex Systems from Simple Components Software Design: Evolutionary, Separation of Concerns Performant, Non-Blocking, Eventual Reliable and Consistent • Handlers do not participate in parent transaction • Handlers are triggered before parent Tx commit/rollback
23. Event-Driven Spring Modulith Transactional Event Listeners
24. Spring Event Listener
25. Complex Systems from Simple Components Software Design: Evolutionary, Separation of Concerns Performant, Non-Blocking, Eventual Reliable and Consistent • Handlers do not participate in parent transaction • Handlers are triggered before parent Tx commit/rollback

27. Event-Driven Spring Modulith
28. Event-Driven Spring Modulith
30. Adding Spring Modulith Events
31. Enabling Event Registry Schema
32. Spring Event Listener
33. Spring Event Listener
34. Complex Systems from Simple Components Software Design: Evolutionary, Separation of Concerns Performant, Non-Blocking, Eventual Reliable and Consistent • Handlers do not participate in parent transaction • Handlers are triggered before parent Tx commit/rollback
35. Event-Driven Spring Modulith
36. Event-Driven Spring Modulith
37. Decoupling Modules with Events (before)
38. Decoupling Modules with Events (after)
39. Complex Systems from Simple Components Software Design: Evolutionary, Separation of Concerns Performant, Non-Blocking, Eventual Reliable and Consistent
40. Event-Driven Spring Modulith Externalizing Events
41. Spring Modulith Events Externalizer
42. Spring Modulith Events Externalizer
43. Spring Modulith Events Externalizer
44. Spring Modulith Events Externalizer
45. Spring Modulith Events Externalizer Convenience ✅ Quick and Convenient API Documentation❌ No built-in support for formal API documentation Schema Management❌ No friction to prevent breaking changes in event schemas that could impact consumers API Governance❌ No standardized way to enforce API design standards: naming conventions, versioning, headers/metadata...
46. API Management with AsyncAPI ✅ API-First Code Generation from AsyncAPI ✅ Reverse Engineering AsyncAPI definition from your Event classes ✅ Spring Modulith Event Externalizer ✅ Spring Cloud Stream - Message<?> ✅ Support for Avro and Json payloads ✅ Support for Headers/Metadata (CloudEvents)
