我在Play Framework中使用Hibernate编写了一个Application。我想用Envers库添加版本。
我有一个用户类。
@Entity
@Audited(withModifiedFlag=true)
public class User
控制器，用于更改用户的某些内容。
@Transactional
public static Result updateAccountStates(Long userId) {
User user = JPA.em().find(User.class, userId);
Integer prevStatus = user.status;
Form<AccountStateForm> form = Form.form(AccountStateForm.class).bindFromRequest();
form.get().applyTo(user);
return redirect(routes.Customers.account(userId));
}
我想向元数据添加有关谁更改了用户数据的信息。
@Entity
@RevisionEntity(UserRevisionListener.class)
public class UserRevisionEntity extends DefaultRevisionEntity {
@ManyToOne
public Staff staff;
}
public class UserRevisionListener implements RevisionListener {
@Override
public void newRevision(Object revisionEntity) {
UserRevisionEntity userEntity = (UserRevisionEntity) revisionEntity;
userEntity = SecurityUtils.getStaff(ctx());
}
}
每次用户更改我都会记录改变它的女巫会员。
我已将UserRevisionEntity模型添加到persistence.xml：
<class>models.UserRevisionEntity</class>
当我更改用户状态时，我得到：

由于未正确创建REV条目，因此无法创建用户修订版。
我不明白为什么会这样。当'newRevision'抛出异常时会发生这种情况，不应该这样做。
感谢您的帮助！
