Reactive Streams and Spring Integration

This chapter explores how reactive streams integrate with Spring Integration patterns and messaging. It focuses on end-to-end reactive flows, adapters, and best practices for building event-driven reactive systems.

What this chapter covers

• How Reactive Streams and Spring Integration complement each other
• Adapters between messaging middleware and reactive publishers
• Composition patterns for long-running streams and back-pressure handling

What you'll learn

• Designing reactive pipelines with Spring Integration components
• Integrating message brokers and reactive data sources
• Testing and monitoring reactive integration pipelines

Roadmap

1. Reactive adapters and common integration recipes
2. Messaging broker patterns (Kafka, RabbitMQ) with reactive consumers/producers
3. Back-pressure, error handling and retries in streaming flows

Examples in this chapter provide recipes and pragmatic guidance for production systems.
