@RequestMapping

@RequestMapping is a Spring annotation used to map web requests to specific handler methods. It can be applied to class-level and method-level in Spring MVC controllers. This annotation allows the developer to specify the HTTP request method, URI pattern, and other request parameters to map the request to a specific method. The @RequestMapping annotation is flexible and can be used to map multiple URIs to the same method, define different request methods, and even apply conditions to the request. It is a powerful feature of Spring MVC that simplifies the request handling process.
