How to Embed tomcat in java [closed]

I am trying to embed tomcat in java application. I searched the google but no luck. i was not able to find good tutorial. is there any complete tutorials or api docs for embedding tomcat. this question might be duplicate of another question. but it seems old. I read that tomcat 7 api over tomcat 6 is lot improved. so i considered it as old. Any links for tutorials is appreciated.

Can we disable Tomcat in spring boot?

If we want to exclude tomcat from spring boot, we don't need to do much, we just need to add one additional block(<exclusions>) to the Spring Boot dependency. <exclusions> tag is used to make us sure that given server/artifactId is being removed at the time of build.

Is Tomcat embedded?

An embedded Tomcat server consists of a single Java web application along with a full Tomcat server distribution, packaged together and compressed into a single JAR, WAR or ZIP file.

there's a more recent tutorial about embedding tomcat 8 here.

the gist of it:

public static void main(String[] args) throws Exception {
    Tomcat tomcat = new Tomcat();
    tomcat.setPort(8080);

    //actually deploy stuff on your tomcat by defining contexts          

    tomcat.start();
    tomcat.getServer().await();
}
