Tasks such as creating the structure for various project artefacts, creating a build file, determining maven coordinates, and picking the right dependency versions can be boring and repetitive. But tragically, Axon Framework isn’t available in the Spring Initializr. So, at AxonIQ, we felt it was high time that we corrected this glaring oversight by providing our very own AxonIQ Initializr just for you, our loyal Axonians!
This blog is a how-to implement a Saga with Axon and Spring Boot. Saga’s are a powerful concept but, you need to think about other options before implementing a Saga.

To help pinpoint the exact implementation areas, let us look at two terms commonly used in Enterprise Architecture - Capabilities and Capability Maps.
