What problem does it solve?

Designing reliable, end-to-end messaging across Spring Boot microservices using established patterns like idempotent consumers, the outbox pattern, transactional events, and dead-letter queues.

Core Features & Use Cases

  • Idempotent consumer and exactly-once-style processing to prevent duplicates
  • Outbox pattern to guarantee event publication only after DB commit
  • Transactional in-process events with @TransactionalEventListener
  • Schema registry support and Avro integration for event schemas
  • RabbitMQ and Kafka configuration best practices including DLQ and acks handling
  • Monitoring and operational guidance for consumer lag and error handling

Quick Start

Wire the provided Kafka and RabbitMQ patterns into your Spring Boot project and implement the documented best practices.
