Spring Boot + Restful Web Service + Spring Security

When we talk about Spring Boot (Simplifying Spring for Everyone) makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR files). Now lets see simple example with combination of Spring Boot and Spring Restful Web Service which includes spring security for all our services or API's.
