GR8Conf 2015 - Spring Boot and Groovy. What more do you need?
The document presents an introduction to Spring Boot and Groovy, highlighting Spring Boot as a fast bootstrap for Spring applications with features like opinionated configurations and standalone application support. It explains the necessary setup, including the required versions of Java and the tools needed for installation, as well as providing code examples for practical use. Additionally, it touches on dependencies management through starters, the integration with Gradle, and mentions Grails as a related framework built on Spring Boot.
