Applying Axon Framework and Spring StateMachine in iQIYI Contract Platform: Architecture, Practices, and Lessons

iQIYI’s contract platform replaced a cumbersome Activiti workflow with a lightweight combination of Axon Framework and Spring StateMachine, leveraging DDD, CQRS, and event sourcing to achieve clear layered architecture, traceable events, and flexible state transitions, while confronting distributed‑transaction sagas, batch limits, and integration complexities, and planning future Axon Server adoption.
