RECQ Components Evento Implementation with Spring Data

Now that we have implemented our payloads we can proceed with implementing components (Aggregates, Projector, Projections, Invokers) handling messages carrying those payloads.

We suggest developing Aggregates and Services first, then Projector and Projections at the end Sagas or Observers. Invokers are the last.

We will proceed with this order:

  • TodoListAggregate

  • TodoList Domain in Spring Data

  • TodoListProjector

  • TodoListProjection

  • TodoListInvoker

  • Todo List Controller in Spring Web
