A Deep Dive into Spring Application Events
summary
Shows that Spring events are synchronous method calls unless annotated with @Async, and that Spring Data’s AbstractAggregateRoot moves event registration into the aggregate so saves auto-publishes domain events. Explains TransactionalEventListener runs on commit (useful for emails) and exposes the bug that failures can lose notifications, then demos an event publication registry prototype persisting event metadata with JPA and Jackson so failed post-commit handlers can be retried or recovered; integration tips and a modulus JUnit extension for testing complete the work.
