Event Driven Microservices with Axon and Spring Boot: excitingly boring
summary
A runnable bike‑rental demo uses Spring Boot plus Axon and optionally Axon Server to turn command handlers into event-sourced aggregates with projections for queries, plus subscription queries that stream updates to the UI. The repo shows splitting the monolith into three process profiles, generating 20 bikes with 10 rentals each and producing about 1,261 spans in Jaeger tracing. Auto‑configuration wires commands, events and queries so the demo replays history, builds new projections and tracing works end‑to‑end with only minimal setup.
