В чем разница между `@Controller` и `@RestController`?

@RestControllerAdvice
public class ApiExceptionHandler {

    @ExceptionHandler(MethodArgumentNotValidException.class)
    public ResponseEntity handleValidation(MethodArgumentNotValidException ex) {
        var errors = ex.getBindingResult().getFieldErrors().stream()
            .map(e -> new FieldError(e.getField(), e.getDefaultMessage()))
            .toList();
        return ResponseEntity.badRequest().body(new ErrorResponse("VALIDATION_FAILED", errors));
    }

    @ExceptionHandler(OrderNotFoundException.class)
    public ResponseEntity handleNotFound(OrderNotFoundException ex) {
        return ResponseEntity.status(HttpStatus.NOT_FOUND)
            .body(new ErrorResponse("ORDER_NOT_FOUND", ex.getMessage()));
    }
}
