Are specific annotations from the Spring package used with @RestController?

The @RestController annotation in Spring combines two annotations: @Controller and @ResponseBody. It is used for creating RESTful web services, where controller methods return data directly in JSON or XML format.

Specific annotations often used together with @RestController for routing and handling HTTP requests include:

• @RequestMapping — for specifying the path and HTTP method (GET, POST, etc.)
• @GetMapping, @PostMapping, @PutMapping, @DeleteMapping — specialized shortcuts for @RequestMapping with specific HTTP methods
• @PathVariable — for obtaining variables from the URL
• @RequestParam — for obtaining request parameters
• @RequestBody — for binding the request body to an object

Example:

@RestController
@RequestMapping("/api/users")
public class UserController {

    @GetMapping("/{id}")
    public User getUser(@PathVariable Long id) {
        // logic to get user by id
    }

    @PostMapping
    public User createUser(@RequestBody User user) {
        // logic to create user
    }
}
