1. Overview

Spring Boot will load properties from the application.properties file which resides in the application class path and add them to the Spring Environment.

This blog post is based on a experimentation I did to integrate Java Swing file chooser on a JRuby on Rails backed web application. Let me warn you, this a dirty hack, wanted to see if the idea would work, not at all recommended for production use. Did this out of curiosity!

Recently I downloaded the latest Spring Tool Suite (STS) with Java 8 SE support. My intention was to give it a try to Stream API on my personal project. An error was shown on the spring security configuration XML once the Maven project is imported to the STS.

The Java properties file can be used to store project configurations or settings.
