I am working on Spring Boot. I have some doubt As i know spring boot has a main() and it calls static run() which is present in SpringApplication. But i want to know what is the flow of Spring boot application ? Can we run spring boot application on server other than tomcat, if yes how ? How to add CROSS Filter in Spring boot application ? As we know in Spring MVC application we configure CROSS Filter in web.xml, but Spring boot we don't have web.xml, So how to configure this ?

How Spring Boot Application works internally?
