我有一个休眠方法可以将一些数据保存到数据库中，它在本地服务器上工作正常，但是当它托管它时，它没有将结果插入到我托管的每个（我的数据库，Web 服务）的数据库中，但它没有插入值。但是当我在我的本地主机上尝试它时，它的工作正常有人可以告诉我为什么会这样
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
我得到的错误
