In this article, I'm going to share with you some of the fundamental techniques and best practices for writing a controller class with the Spring MVC framework. Typically, in Spring MVC, we write a controller class to handle requests coming from the client.
Then, the controller invokes a business class to process business-related tasks, and then redirects the client to a logical view name, which is resolved by Spring’s dispatcher servlet in order to render results or output. That completes a round trip of a typical request-response cycle.
