Why does HATEOAS + @JsonView return an empty object?

Question

JSON

There is an object with a certain set of fields c @JsonView:

public class OrderDto extends AbstractDto<OrderDto> {
    @Valid
    private UserDto user;

    @Valid
    private GiftCertificateDto giftCertificate;

    @JsonView(View.FindOrderForUser.class)
    private BigDecimal price;

    @JsonView(View.FindOrderForUser.class)
    private LocalDateTime purchaseDate;
}

Why do I get a void when returning this object OrderDtoin the controller along with links HATEOASin response:

@GetMapping(UrlMapping.ORDER_USER)
    @JsonView(View.FindOrderForUser.class)
    public EntityModel<OrderDto> findOrderForUser(@PathVariable long userId, @PathVariable long orderId) {
        OrderDto orderDto = orderService.findOrderForUser(orderId, userId);
        return EntityModel.of(orderDto);
    }

Result:

{}

But if I return a simple object OrderDto, then everything works and only the annotated @JsonViewfields are displayed:

@GetMapping(UrlMapping.ORDER_USER)
@JsonView(View.FindOrderForUser.class)
public OrderDto findOrderForUser(@PathVariable long userId, @PathVariable long orderId) {
    return orderService.findOrderForUser(orderId, userId);
}

Result:

{
    "createDate": "2021-06-25T21:38:01",
    "lastUpdateDate": "2021-05-21T17:19:06"
}

But in this case, you need HATEOASlinks to be present and the result is like this:

{
    "price": 1.00,
    "purchaseDate": "2021-11-15T10:38:45.193",

    "_links": {
        "self": {
            "href": "http://localhost:8080/orders/1"
        }
    }

Also in application.properties, I set the property spring.jackson.mapper.default-view-inclusion=true, but the controller method, in this situation, returned all the fields of the OrderDto object.

@JsonIgnore- not a solution, because sometimes I need to output as JSON all the fields of the OrderDto object, and in some situations, like this, not all fields.
