@JsonIgnoreProperties for ArrayList how to do?

Question

Java

Hello!
There are two entities in my tutorial project: Animal and Client. This is an animal and a master. Each entity has a link to another, that is, Animal has a Client field, and vice versa. Entities are connected Many-to-One, an animal has only one owner, but one owner can have several animals.
The essence of the question is that I have a REST controller, and when I receive some kind of getClientById, I get a recursion where the client refers to the animal, and that, in turn, to the client, and so on in a circle.
I got around this with the @JsonIgnoreProperties annotation. But in the many-to-one case, everything works fine:

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "client_id", insertable = false, updatable = false)
@JsonIgnoreProperties("animal")
private Client client;

and in the opposite case, all shit does not work perfectly:

@OneToMany(fetch = FetchType.LAZY, mappedBy = "client", cascade = CascadeType.ALL)
@JsonIgnoreProperties(value = { "client", "complaints" })
private List<Animal> animals;

and I even kind of know why: JsonIgnoreProperties looks at the fields of the List, instead of the Animal fields for each list item.

Maybe someone knows and tell me how to get around this? Thanks in advance

Answer 1

it is necessary not to ignore, but to put @JsonBackReference and that's it. there will be no cyclic dependency
