@GetMapping is an annotation used to map HTTP GET requests onto specific handler methods in a controller.
-It's a shortcut for @RequestMapping(method = RequestMethod.GET), providing a more concise way to declare mappings for GET requests.
1. Concise Mapping:
@GetMapping provides a more concise way to declare mappings for HTTP GET requests compared to using @RequestMapping with method = RequestMethod.GET. This improves the readability and maintainability of the code.
2. Readability:
By using @GetMapping, the intention of the handler method is explicitly clear. Developers can easily understand that the method is meant to handle GET requests, enhancing the readability of the codebase.
3. Convenience:
It simplifies the development process by reducing the amount of boilerplate code required to define request mappings for GET requests..
4. Type Safety:
@GetMapping helps to catch errors at compile time. If you mistakenly use it on a method that doesn't support GET requests, the compiler will generate an error, providing immediate feedback to the developer
