Introduction to Spring Boot

Spring Boot allows Java developers to create standalone Spring applications that "just run," typically using an embedded instance of Tomcat, Jetty, or Undertow.  These Spring Boot applications require no code generation or XML configuration, while at the same time they feature integrated health monitoring, simplified Maven configuration, and a host of other features that make building, deploying, and running your Spring applications far easier.
