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

@Entity
class Comment(text: String, postedBy: Profile) : Serializable {

    @Id
    @GeneratedValue
    var id: Long? = 0

    var text: String? = text

    @JsonIgnore
    @JsonProperty("accCreatedTime")
    var accCreatedTime: Instant? = Instant.now()

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

Here we have three elements and one constructor. Here is the constructor:

@Entity
class Comment(text: String, postedBy: Profile) : Serializable {
   -----
   -----
}
