@JsonIdentityReference与alwaysAsId = true

Question

BaseEntity：

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@JsonInclude(JsonInclude.Include.NON_EMPTY)
@JsonPropertyOrder({"id", "posId", "posCode", "title", "description", "sortOrder"})
public class BaseEntity {
    private UUID id = UUID.randomUUID();
    private String posId;
    private String posCode;
    private String title;
    private String description;
    private Integer sortOrder;
}

IntegrationCategory：

@Getter
@Setter
@NoArgsConstructor
@JsonInclude(JsonInclude.Include.NON_EMPTY)
public class IntegrationCategory extends BaseEntity {
    private boolean root;
    private Integer rootSortOrder;

    private Collection<IntegrationSubCategoryInCategory> subCategories = new ArrayList<>();
}

IntegrationSubCategoryInCategory：

@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@Builder
@JsonInclude(JsonInclude.Include.NON_EMPTY)
public class IntegrationSubCategoryInCategory {
    @Getter(onMethod = @__( @JsonIgnore ))
    private IntegrationCategory category;

    @JsonProperty(
        required = true,
        index = 1
    )
    @JsonIdentityInfo(
        property = "id",
        generator = ObjectIdGenerators.PropertyGenerator.class
    )
    @JsonIdentityReference(
        alwaysAsId = true
    )   
    private IntegrationCategory subCategory;
    private Integer sortOrder;
}

此类将生成类似JSON的

"categories": [
        {
            "id": "8d62eb47-5491-4142-8b87-cde558165be8",
            "posId": "31000",
            "posCode": "31000",
            "title": "Coneys",
            "description": "Coneys",
            "root": true,
            "rootSortOrder": 1,
            "subCategories": [
                {
                    "subCategory": "72b2a181-8e76-4932-8201-56a847f95153",
                    "sortOrder": 1
                }
            ]
        },
        {
            "id": "72b2a181-8e76-4932-8201-56a847f95153",
            "posId": "31100",
            "posCode": "31100",
            "title": "Cheese Coney",
            "description": "Cheese Coney",
            "root": false
        },
...

序列化效果很好。当我尝试反序列化此JSON时，问题就开始了。

com.fasterxml.jackson.databind.deser.UnresolvedForwardReference: Could not resolve Object Id [72b2a181-8e76-4932-8201-56a847f95153] (for [simple type, class com.company.common.integration.protocol.digitalordering.model.IntegrationCategory]).at [Source: (StringReader); line: 1, column: 310] (through reference chain: com.company.common.integration.protocol.digitalordering.response.GetPosMenuResponse["menu"]->com.company.common.integration.protocol.digitalordering.MenuAggregator["categories"]->java.util.ArrayList[0]->com.company.common.integration.protocol.digitalordering.model.IntegrationCategory["subCategories"]->java.util.ArrayList[0]->com.company.common.integration.protocol.digitalordering.model.IntegrationSubCategoryInCategory["subCategory"])

问题似乎是杰克逊不知道类别“ Coneys”中具有“ Cheese Coneys”子类别的ID（UUID）的对象，对于Jackson来说是未知的，因为具有该UUID的类别“ Cheese Coneys”位于“类别Coneys”之下。 / p>

Jackson可以解决这种情况下的ID吗？我在做什么错了？
