Spring Boot - Modularizing project into modules and re-use

While working with microservices, there will be many small modules in your systems, they calls each others, for me it would be great if we can share at least the data transfer classes. It will save time on development

Here is the structure of my example

In the example, I created a rest-module-example module, it is the main module which separated into 2 modules ( dto.jar and app.jar )

The rest-module-consumer-example will include the dto.jar ( by Maven or Gradle ) , so It will be easy to consume the REST API

You can find details implementation in the repos below:

Spring Boot 2 - REST template project

Recently, I have a chance to work with Spring Boot, it was pretty hard for me to create Spring project without template that is ready for development. So I created a template to help me save time for next projects.
