Create a like entity named LikeObj.kt with the @Entity annotation to convert this class into an entity class. Here is the code of this model class:

@Entity
class LikeObj(mProfile: Profile) : Serializable {

    @Id
    @GeneratedValue
    var id: Long? = 0

    @ManyToOne
    @JoinColumn(name = "profile_id")
    @JsonIgnoreProperties("username","password","email","accCreatedTime","firstName","lastName",
            "contactNumber","dob","city","country")
    var profile: Profile? = mProfile
}

Here we have one element and one constructor. Here is the constructor:

@Entity
class LikeObj(profile: Profile) : Serializable {
   -----
   -----
}
