java - 为什么这段代码在 netbeans 中抛出 ClassCastException 而在 eclipse 中运行良好

Question

//运行时异常 在netbeans中调用以下代码时会发生运行时异常。在 eclipse 中工作正常。

    public List<Ticket> findOpenTickets() {
            Session session = null;

            try {
                session = getSession();
                Criteria criteria = session.createCriteria(getReferenceClass());
                            criteria.add(Restrictions.eq(Ticket.PROP_CLOSED, Boolean.FALSE));
                List list = criteria.list();
                return list;
            } finally {
                closeSession(session);
            }
        }

异常堆栈跟踪是

我无法解决这个异常。因为一切似乎都很好，相同的代码在 Eclipse 中运行良好，但产生运行时异常。

检查你的 hibernate.dialect 是否正确？它必须是您的数据库的..
