JPA双向关系-无限循环/循环引用

我的关系是双向的

@Entity
@Table(name = "facility")
public class Facility implements Serializable {

    @Id
    @GeneratedValue
    private Long id;

    @OneToMany(mappedBy = "facility")
    private Set<Amenity> amenities;
}

@Entity
@Table(name = "amenity")
public class Amenity  implements Serializable {
    @Id
    @GeneratedValue
    private Long id;

    @ManyToOne
    private Facility facility;
}

当然有一个循环引用，每个实体引用另一个实体。您使用什么来遍历对象树？无论您使用什么代码来构建JSON对象，都需要知道不要“返回”对象树。你能解释一下它是如何工作的吗？

[
    {
        "id": 1,
        "facilityName": "asdf",
        "facilityCode": "asdf",
        "amenities": [
            {
                "id": 15,
                "amenityType": "amenity 1",
                "facility": {
                    "id": 1,
                    "facilityName": "asdf",
                    "facilityCode": "asdf",
                    "amenities": [
                        {
