SpringBoot MVC with Example:
In this article let us see an example of MVC (Model View Controller) with SpringBoot.
This is an simple example of SpringBoot MVC, without involving database. We are going to use @RestController with mapping and deploy the application.
Why SpringBoot MVC and Why not Spring MVC?
The main advantage of using SpringBoot for MVC over Spring MVC is,
Spring Boot does this with Zero XML configuration in your project. We will not be needing deployment descriptors or any other configuration files.
Let us see an example,
