Spring Boot

From My Limbic Wiki


  • Big environment wich is use to help us develop applications.
  • if Spring MVC need configuration ? Spring Boot does it.
  • Other jars needed to develop web applications ? there are starters allowing to easily build application
  • Monitoring, and developer friendly tools
  • Good integration with embeded servers: No need to develop a WAR file always, it is possible to develop a JAR and directly run it cause the Tomcat server is directly inside the JAR.
