带有休眠惰性初始化对象的Spring Data Rest HAL响应格式问题

如何解决带有休眠惰性初始化对象的Spring Data Rest HAL响应格式问题

技术堆栈：Spring Boot（2.3.1.RELEASE），Spring Data JPA，Sprign Data Rest（3.3.1 RELEASE），Hibernate（5.4.17 Final），Postgresql。我有上级实体 ProductEntity ：

@Data
@Entity
@Table(name = "product")
@EntityListeners(AuditingEntityListener.class)
public class ProductEntity {

    @NotNull
    @Id
    @EqualsAndHashCode.Exclude
    @Type(type = "pg-uuid")
    @GeneratedValue(generator = "uuid2")
    @GenericGenerator(name = "uuid2",strategy = "uuid2")
    private UUID id;

    @JsonProperty("productType")
    @ToString.Exclude
    @OnetoOne(mappedBy = "productEntity",cascade = CascadeType.ALL,fetch = FetchType.LAZY,orphanRemoval = true,optional = false)
    private ProductTypeEntity productTypeEntity;
}

结束子实体 ProductTypeEntity ：

@Data
@EqualsAndHashCode(callSuper = true)
@ToString(callSuper = true)
@Entity
@Table(name = "product_type")
@JsonIgnoreProperties({"hibernateLazyInitializer"})
public class ProductTypeEntity extends BaseEntity implements RootAware<ProductEntity> {
    
    @NotBlank
    @Size(max = 255)
    private String type;

    @NotBlank
    @Size(max = 255)
    private String brand;

    @OnetoOne(fetch = FetchType.LAZY,optional = false)
    @MapsId
    @JoinColumn(name = "id")
    @ToString.Exclude
    @EqualsAndHashCode.Exclude
    @JsonIgnore
    private ProductEntity productEntity;

    @Override
    public ProductEntity root() {
        return productEntity;
    }
}

最后有一个Spring Data REST存储库 ProductRepository ：

@RepositoryRestResource(collectionResourceRel = "products",path = "products")
public interface ProductRepository extends JpaRepository<ProductEntity,UUID> {

}

主要问题是当我请求 GET http：// localhost：8081 / api / v1 / products 时，我收到了其他字段 content 在 productType 下是完全多余的，并且无法对响应进行足够的解析：

{
    "_embedded": {
        "products": [
            {
                "productType": {
                    "content": {
                        "type": "type1","brand": "brand1"
                    }
                }
                "_links": {
                    "self": {
                        "href": "http://localhost:8081/api/v1/products/6b0e375e-4d2d-41af-b42f-989859652c81"
                    },"productEntity": {
                        "href": "http://localhost:8081/api/v1/products/6b0e375e-4d2d-41af-b42f-989859652c81"
                    }
                }
            }
        ]
    },"_links": {
        "self": {
            "href": "http://localhost:8081/api/v1/products"
        },"profile": {
            "href": "http://localhost:8081/api/v1/profile/products"
        }
    },"page": {
        "size": 20,"totalElements": 1,"totalPages": 1,"number": 0
    }
}

但是当我将productTypeEntity从 LAZY 更改为 EAGER 时：

@JsonProperty("productType")
@ToString.Exclude
@OnetoOne(mappedBy = "productEntity",fetch = FetchType.EAGER,optional = false)
private ProductTypeEntity productTypeEntity;

我收到正确的答复，但没有内容字段：

{
    "_embedded": {
        "products": [
            {
                "productType": {
                    "type": "type1","brand": "brand1","_links": {
                        "productEntity": {
                            "href": "http://localhost:8081/api/v1/products/6b0e375e-4d2d-41af-b42f-989859652c81"
                        }
                    }
                },"_links": {
                    "self": {
                        "href": "http://localhost:8081/api/v1/products/6b0e375e-4d2d-41af-b42f-989859652c81"
                    },"number": 0
    }
}

主要问题是此行为背后的原因是什么。我无法采用和使用它，因为我无法理解它的性质以及它是否可以解决。
