title: How to keep springboot application alive after exiting putty
body: <p>I am running my spring boot application on my server using putty via command 
  mvn spring-boot:run and it runs only when I have open ssh session. Is it possible to keep application alive after I disconnect session?
  Or do I have to make executable war file and deploy to installed tomcat server on my ubunntu 14.04. 
  I know others ways to deploy boot apps but I want to know if it is possible in my approach.</p>
