我对Envers（历史创造者）在Mediator Class中的应用有疑问。

问题是，当关系中的对象更改值时，如何在中介类中应用审计。

例如，在我的 ProjectMediator 课程中，我遇到了这种情况：

@Entity
@NamedQueries({
        @NamedQuery(name = "ProjectMediator.findProjectMediatorByIdProject",
                    query = "SELECT pm FROM ProjectMediator pm WHERE pm.project.id = :idProject") 
                            })
@Audited
public class ProjetMediator implements Serializable {

    private static final long serialVersionUID = 1L;

    public static final String FIND_PROJECT_BY_ID_PROJECTMEDIATOR = "ProjectMediator.findProjectMediatorByIdProject";

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

    @OneToOne
    @JoinColumn(name="id_project")
    private Project project;


    @ManyToMany( targetEntity=Task.class, fetch=FetchType.LAZY )
    private List<Task> tasks;

    @ManyToMany( targetEntity=Activite.class, fetch=FetchType.LAZY )
    private List<Acitvity> activities;

    @ManyToMany( targetEntity=Phase.class, fetch=FetchType.LAZY )
    private List<Phase> phases;
   //get and sets }

而我需要在Phase对象改变值时创建一个history，所以history需要ProjectMediator的id、id Phase和data Phase。

任何人都知道如何创建类似的东西？

太感谢了！！
