我有一个hibernate方法将一些数据保存到数据库中，它在本地服务器上正常工作但是当它托管它不插入结果到我托管的每个数据库（我的数据库，Web服务）但它没有插入valuse。但是当我在我的本地主机上尝试它的工作正常时，任何人都可以告诉我为什么会这样做
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
错误我正在

典型的交易应使用以下习语：
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();
}
