Where in the Spring configuration is the HTTP method for handling requests defined?

In Spring, the HTTP method for handling requests is specified in controller annotations such as @GetMapping, @PostMapping, @PutMapping, @DeleteMapping, etc., or in a more general @RequestMapping annotation with the method parameter.

Example:

@RestController
public class MyController {
    @GetMapping("/items")
    public List<Item> getItems() {
        return ...;
    }

    @RequestMapping(value = "/items", method = RequestMethod.POST)
    public Item createItem(@RequestBody Item item) {
        return ...;
    }
}

Thus, the HTTP method is set directly in the controller configuration via annotations, rather than in separate configuration files.
