I want to use Websphere liberty in spring boot application instead of tomcat server. If I am correct it is not supported out of the box. How can I configure spring boot/websphere liberty to achieve this?
Using the Liberty app accelerator you can download a zip containing a Maven buildable 'Spring Boot with Spring MVC' app as your starting point. Just run mvn install and you'll get the app running at http://localhost:9080/myLibertyApp/
Actually, you can now create runnable jar files with WebSphere Liberty. You need v8.5.5.9 or higher. Create a runnable jar this way:
server package {server name} --archive={jar name}.jar --include=minify,runnable
Resultant jar can be run as you'd expect:
java -jar {jar name}.jar
Since very recently (May 2018) you can deploy a Spring Boot jar with Liberty, as it seems. See https://developer.ibm.com/wasdev/blog/2018/05/11/spring-boot-applications-on-liberty/. Haven't tried it out yet, though.
