how to put entity associations in JSON (inside POST HTTP request) while performing CREATE operation of entity has association of another entity?

I am using Spring Boot as my backend framework and I have a PERSON entity which has a one-to-one relation with GENDER entity. I am using @RepositoryRestResource for PersonRepository and GenderRepository.

The GENDER table is already filled with two records of MALE and FEMALE and I have an angular form which creates a new PERSON.

In angular form, there is a list of genders with two items gotten from GenderRepository (male/female). how can I put the genderId in JSON of POST Request body to create a new Person.

I see that most of people use text/uri-list to update existing records however I want to set it while creating not updating.

You can do that by giving a link to the gender entity.

Person Entity


@Entity
public class Person {
    @Id
    @GeneratedValue
    private Long id;

    @OneToOne
    private Gender gender;

    //Other columns and getter/setters are removed for brevity
}

Gender Entity

@Entity
public class Gender {
    @Id
    @GeneratedValue
    private Long id;

    @Column
    private String gender;
}

The following POST request to localhost:8080/api/persons with Content-Type header set to application/json creates a new Person entity and sets it's gender to the Gender with the id of 1.

{
    "name": "Mahsum",
    "surname": "Demir",
    "gender": "http://localhost:8080/api/genders/1"
}
