Spring Boot Overview

Spring Boot is a Spring module that provides the RAD feature to the Spring framework. Spring Boot makes easy to create a stand-alone, production-based application that can “just run” with very little configuration. It doesn’t generate code and not require an XML configuration.

You can create a Java application that can run by command java -jar or create traditional web application by creating war and deploy on the server.
