Hola:

Para insertar el objeto Issue uso el siguiente código:

Código C:

IssueService is = new IssueService();
        
Issue i1 = new Issue();
        
is.add(i1);
 

- Clase Issue

Código C:

@Entity
@Table(name = "table_issue")
public class Issue implements IIssue {
 
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "issueNumber", unique = true)
    private int issueNumber;
 
    @Column(name = "name")
    private String name;
 
    @Column(name = "email", unique = true)
    private String email;
 
    @Column(name = "description")
    private String description;
 
    @ManyToOne(cascade = CascadeType.PERSIST, targetEntity = Product.class)
    @JoinColumn(name = "code_p")
    private IProduct product;
 
    @ManyToOne(cascade = CascadeType.PERSIST, targetEntity = MaintenanceProcedure.class)
    @JoinColumn(name = "code_mp")
    private IMaintenanceProcedure maintenanceProcedure;
 
    @ManyToOne(cascade = CascadeType.PERSIST, targetEntity = Technician.class)
    @JoinColumn(name = "technicianNumber")
    private ITechnician technician;
 
    @Column(name = "response")
    private String response;
 
    @Column(name = "punctuation")
    private int punctuation;
 
    @ManyToMany(cascade = CascadeType.PERSIST, targetEntity = Issue.class)
    @JoinColumn(name = "issueNumber")
    private Set<IIssue> recordList = new HashSet<IIssue>();
