Spring Boot adopts the simplest approach to building a standalone application that runs on an embedded web server. It creates an executable archive (JAR) file that contains everything, including an entry point defined by a class that contains the main() method. For making it an executable JAR file, you use Spring's support for embedding the Jetty servlet container as the HTTP runtime, instead of deploying it to an external instance for execution.
Therefore, we would create the executable JAR file in place of the WAR that needs to be deployed on external web servers, which is a part of the rest module. We'll define the domain models in the lib module and API related classes in the rest module.
We need to create separate pom.xml files ...
