Building highly modular and testable business systems with Spring Integration
summary
Claim: modular business features become standalone, testable services that deploy and scale. Uses Spring Integration components (channels, endpoints, routers, splitter, aggregator), packaged as Spring Boot apps, serialized as JSON and connected over RabbitMQ; three cafe modules (order split, drink prep, delivery) run as separate processes and scale by adding instances, demonstrated live. Modules also deploy to Spring XD where input/output channel conventions and built‑in bridging remove manual adapters. The demo works end‑to‑end with visible concurrency and failover.
