Yes, the @RestController annotation in Spring is used for creating RESTful web services. It combines @Controller and @ResponseBody, allowing controller methods to automatically return data in JSON or XML format. For example:

@RestController
public class UserController {

    @GetMapping("/users/{id}")
    public User getUser(@PathVariable Long id) {
        // logic to get user by id
        return userService.findById(id);
    }
}

This controller handles HTTP requests and returns data directly to the client without additional serialization.
