What's the difference between @GetMapping and @RequestMapping(method = RequestMethod.GET)?
I've seen in some Spring Reactive examples, that
@GetMapping was used instead of @RequestMapping

@GetMapping is a composed annotation that acts as a shortcut for @RequestMapping(method = RequestMethod.GET).
@GetMapping is the newer annotaion.
It supports consumes
Consume options are :
consumes = "text/plain"
consumes = {"text/plain", "application/*"}
For Further details see: GetMapping Annotation
or read: request mapping variants
RequestMapping supports consumes as well
GetMapping we can apply only on method level and RequestMapping annotation we can apply on class level and as well as on method level

As you can see here:
Specifically,
@GetMappingis a composed annotation that acts as a shortcut for@RequestMapping(method = RequestMethod.GET).Difference between
@GetMapping&@RequestMapping
@GetMappingsupports theconsumesattribute like@RequestMapping.

@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)

Short answer:
There is no difference in semantic.
Specifically, @GetMapping is a composed annotation that acts as a shortcut for @RequestMapping(method = RequestMethod.GET).
Further reading:
RequestMapping can be used at class level:
This annotation can be used both at the class and at the method level. In most cases, at the method level applications will prefer to use one of the HTTP method specific variants @GetMapping, @PostMapping, @PutMapping, @DeleteMapping, or @PatchMapping.
while GetMapping only applies to method:
Annotation for mapping HTTP GET requests onto specific handler methods.
