Technologies used in this article :

  1. Spring boot
  2. Maven

NB: The creation of spring using spring boot and Maven is explained here http://mkaroune.e-monsite.com/pages/spring-boot-hiberante-project/project-creation.html. You do not need to add all the dependencies as shown in the article. Only DevTools, Web and Thymeleaf are needed in this example
