Hibernate 在服务器上插入数据时出现问题

我有一个hibernate方法将一些数据保存到数据库中，它在本地服务器上工作正常，但当它托管时，它没有将结果插入到我托管的数据库中（我的数据库，web服务），但它没有插入值。但当我在本地主机上试用时，它的效果很好，有人能告诉我为什么吗

try {

            session.beginTransaction();

            LabOrder order = (LabOrder) session.get(LabOrder.class, oID);

            Lab lab = (Lab) session.get(Lab.class, lID);

            speciman.setOrderID(order);

            speciman.setLabID(lab);

            session.save(speciman);

            session.getTransaction().commit();

            session.close();

            return true;

        } catch (RuntimeException ex) {
            ex.getMessage();
        }

这是我用来保存数据的代码段

我犯了一个错误

典型的事务应使用以下习惯用法：

Session sess = factory.openSession();
 Transaction tx;
 try {
     tx = sess.beginTransaction();
     //do some work
     ...
     tx.commit();
 }
 catch (Exception e) {
     if (tx!=null) tx.rollback();
     throw e;
 }
 finally {
     sess.close();
 }

您的服务器日志中是否存在异常？是的，存在异常，但OP在执行

ex.getMessage（）时未打印该异常。这应该是
ex.printStacktrace（）如果您放置printStackTrace（）语句，在服务器上重新部署，并发送堆栈跟踪以进行更多调查，那就太好了。实际上，当我尝试执行该方法时，它说它已成功插入到db中，但在b值旁边没有插入，因此没有
ex.getMessage（）消息在服务器日志中有一个错误，显示
LabOrder=（LabOrder）session.get（LabOrder.class，oID）获取空指针异常，LabOrder类有很多外键，所以是否有方法获取LabOrder类，请帮助我的代码在本地主机上工作良好问题是当它部署到服务器时
