Recursivity with Spring and Jackson

Question

I need to create a model with tree entities, all of then have a reference between another, I need to serializate this to my AngularJS application, using Jackson's API but, when I hit the endpoint, the JSON that is returned is wrong. There's anyway to make this? A better way or a way to fix it?

Place class:

@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
@Entity(name = "od_places")
public class place {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column
    private String name;

    @Column
    private int number;

    @Column
    private int zone;

    @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true)
    @JoinColumn(name = "place_id")
    private List<Dweller> dwellers;

    @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true)
    @JoinColumn(name = "id")
    private List<Route> routes;

    @Column
    private Geometry geom;

    @Column
    private float x;

    @Column
    private float y;

    @Column
    private Date lastUpdate;

    @Column
    private Date regDate;

    @Column
    private boolean disabled;
}

Dweller class:

@Entity(name = "od_dweller")
public class Dweller {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column
    private String gender;

    @Column
    private boolean deficientient;

    @Column
    private String ageRange;

    @Column
    private String schooling;

    @Column
    private String ocupation;

    @ManyToOne
    private Place place;

    @Column
    private Date lastUpdate;

    @Column
    private Date regDate;

    @Column
    private boolean disabled;
}

Route class:

@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
@Entity(name = "od_routes")
public class Route {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column
    private String weekDay;

    @Column
    private int trip;

    @OneToOne(orphanRemoval = true)
    private Place origin;

    @Column
    private String departureTime;

    @OneToOne(orphanRemoval = true)
    private Place destiny;

    @Column
    private String arrivalTime;

    @OneToOne(orphanRemoval = true)
    private Dweller dweller;

    @Column
    private String reason;

    @Column
    private String travelMode;

    @Column
    private Date lastUpdate;

    @Column
    private Date regDate;

    @Column
    private boolean disabled;
}

A few things to make it clear: I really need the list on Place model because I want to every place I load to come with his routes. I'm working with Postgres. All the data is MOCK.

What I want: I want to solve this, make it better and learn why and how to make this works.

Answer 1

The answer that Nikolai Shevchenko gave on the comments worked for me!

"In your Place you have one-to-many relation with Route and Dweller while in Route and Dweller you have one-to-one relation (backward) with Place. So first you should properly design your tables. Also this link might be helpful with recursive Jackson references https://www.baeldung.com/jackson-bidirectional-relationships-and-infinite-recursion"
