title: How to migrate from traditional java web application (with web.xml) to spring boot?
body: <p>I wanna switch my projects to spring-based product.</p>
  
  <p>My first step is to transform my java web application from a generated WAR file, to a standalone executable jar, powered by spring boot.</p>
  
  <p><a href="https://github.com/xpoft/vaadin-samples/blob/master/spring-integration">Let's take a open source web application example from github.: Vaadin-Spring Web Application</a></p>
  
  <p><a href="https://github.com/xpoft/vaadin-samples/blob/master/spring-integration/src/main/webapp/WEB-INF/web.xml">The web.xml file can be found here.</a></p>
  
  <p><a href="https://github.com/xpoft/vaadin-samples/blob/master/spring-integration/src/main/webapp/WEB-INF/root-context.xml">The root-context file can be found here.</a></p>
  
  <p>I hope that there are some guides for me to perform the transformation.</p>
