In the previous post you could read about separate Spring Boot builds for a local development machine and public environments. It’s highly possible that in addition to such setup you would like to load different Spring properties files based on the active Maven profile. In this note you will learn how to accomplish the desired result in a few easy steps.
The great thing about Spring Boot is no need for an external servlet container. All that is needed reside inside a single runnable JAR file. In a very few steps, development of a new application can be started without installation or configuration of any additional software.
Yet, sometimes you might want to deploy your application to some server as a regular WAR file. For instance, you convert an existing application and want to keep your continuous delivery pipe untouched or a particular container is enforced by a company’s policy. The reason for building a WAR file may vary across teams, but for development purpose a simple executable JAR file with an embedded server might be preferable.
