In this video we will go in-depth about Spring Boot’s maven plugin called Spring-Boot-Maven-Plugin. This plugin helps to build executable spring boot jar which can run without a web server. This FAT jar can be lunched with just a java -jar command and can help us to deploy our app without an external server.

This helps to lunch and deploy our code quickly in an efficient way.

Every jar’s are different with respect to the way they have been packaged. Eg.

Skinny - Only contains the File that you write in your editor. That’s it !

Thin - Contains all the above + the application direct dependencies (Library, drivers etc)

FAT / Uber Jar - Contains all the files that you write in your editor + Application dependencies + a runtime environment which is needed your application to run by itself.

In spring boot we deal with the FAT or Uber Jar. This helps to lunch our app without any external server like tomcat.

Let’s get started with this spring boot tutorial and I will make sure this is beginner friendly.
