This annotation is a versatile and flexible annotation that can be used with a controller (class) as well as the methods to map specific web requests with the handler methods and controllers. This annotation is part of a larger set of annotations provided by Spring Framework to define URL endpoints and simplify the development of Spring Boot applications.

It has the following features:

• Define several different endpoints to access a specific resource.
• Build REST APIs to serve web requests.
• Simplify the web development process by simply defining an annotation that offers a set of functionalities for handling requests.
• Define multiple endpoints in a single @RequestMapping annotation.
