[java] Difference between the annotations @GetMapping and @RequestMapping(method = RequestMethod.GET)

@RequestMapping is a class level

@GetMapping is a method-level

With sprint Spring 4.3. and up things have changed. Now you can use @GetMapping on the method that will handle the http request. The class-level @RequestMapping specification is refined with the (method-level)@GetMapping annotation

Here is an example:

@Slf4j
@Controller
@RequestMapping("/orders")/* The @Request-Mapping annotation, when applied
                            at the class level, specifies the kind of requests 
                            that this controller handles*/  

public class OrderController {

@GetMapping("/current")/*@GetMapping paired with the classlevel
                        @RequestMapping, specifies that when an 
                        HTTP GET request is received for /order, 
                        orderForm() will be called to handle the request..*/

public String orderForm(Model model) {

model.addAttribute("order", new Order());

return "orderForm";
}
}

Prior to Spring 4.3, it was @RequestMapping(method=RequestMethod.GET)
