I have seen a project which uses Maven submodules. The project itself is a spring boot application that exposes Restful API endpoints for a microservice ex: Customer Service (getCustomers, createCustomers etc); consisting of standard model classes, repository, service interface&implementations, controllers etc.
Is there a good reason why we want to make model classes, repository, service interface&implementations, controllers, submodules ?
To be clear, i'm comparing these 2:
1) Normal case:
Project src main java dao model service controller resources test ... pom.xml
2) Submodules case:
Project dao src main java dao resources test ... pom.xml service src main java service resources test ... pom.xml
Why go for no 2?
To me this structure looks really complex with each pom.xml in each submodule folder..
