Question

public void updateAwardWithoutFileUpload(String[] s) {
    Query q = em.createNamedQuery("Award.findByAwardid");
    q.setParameter("awardid", Integer.parseInt(s[0]));
    Award a = (Award) q.getSingleResult();

    a.setAwardTitle(s[1]);
    a.setAwardYear(s[2]);
    a.setAwardRecipientName(s[3]);
    a.setAwardRecipientType(s[4]);
    a.setAwardResult(s[5]);
    em.persist(a);
}

在em.persist（a）之后，我收到了由...引起的异常引起：javax.validation.ConstraintViolationException：在回调事件上执行自动Bean验证时违反了Bean验证约束：＆＃39; preUpdate＆＃39;。有关详细信息，请参阅嵌入式ConstraintViolations。

和

引起：javax.transaction.RollbackException：标记为回滚的事务。

能告诉我是什么原因吗？

与建议问题不同，我的例外是预先更新的，建议问题是prePresist
