Entidade

⬇️ Lembrar de criar Getters and Setters + equals&hashcode com ID.

❗Nunca coloque um Set do relacionamento dentro do construtor.

@Entity
@Table(name = "tb_reply")
public class Reply {

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

    @Column(columnDefinition = "TEXT")
    private String body;

    @Column(columnDefinition = "TIMESTAMP WITHOUT TIME ZONE")
    private Instant moment;

    @ManyToOne
    @JoinColumn(name = "author_id")
    private User author;

    @ManyToOne
    @JoinColumn(name = "topic_id")
    private Topic topic;

    @ManyToMany
    @JoinTable(name = "tb_reply_likes",
            joinColumns = @JoinColumn(name = "reply_id"),
            inverseJoinColumns = @JoinColumn(name = "user_id")
    )
    private Set<User> likes = new HashSet<>();
