我有一个奇怪的问题，它只发生在参考服务器上，我的本地环境中的相同代码按预期工作。阅读一些记录后，我正在尝试进行批量更新。

我写的JAVA代码是

public OrderDTO findRecurringOrder(Integer userId, Integer itemId) {
        Criteria criteria = getSession().createCriteria(OrderDTO.class)
                .createAlias("orderStatus", "s")
                .add(Restrictions.eq("s.id", Constants.ORDER_STATUS_ACTIVE))
                .add(Restrictions.eq("deleted", 0))
                .createAlias("baseUserByUserId", "u")
                .add(Restrictions.eq("u.id", userId))
                .createAlias("orderPeriod", "p")
                .add(Restrictions.ne("p.id", Constants.ORDER_PERIOD_ONCE))
                .createAlias("lines", "l")
                .createAlias("l.item", "i")
                .add(Restrictions.eq("i.id", itemId))
                .addOrder(Order.desc("id"))
                .setMaxResults(1);

        return findFirst(criteria);
    }

public T findFirst(Criteria criteria) {
        criteria.setFirstResult(0).setMaxResults(1);
        return (T) criteria.uniqueResult();

    }

我得到的错误堆栈跟踪是：

有什么建议吗，我真的对这个 Hibernate 异常知之甚少？

它看起来不像是休眠错误。看一下第一行：

groovy.lang.MissingMethodException: No signature of method: com.sapienter.jbilling.server.order.db.OrderLineDTO.validate() is applicable for argument types: (java.util.LinkedHashMap) values: [[deepValidate:false]]

显然，您在OrderLineDTO类型的对象中调用validate()并在只需要传递 (deepValidate:false) 时传递 Map ([deepValidate:false])。您可以在此处查看 validate 的其他用途。
