Question

在我们的一个生产环境中，我们首先在线程上连续出现hibernatestaleobject异常。这一直持续到我们重启服务器。

环境：oracle 10g，WAS 6.1，Hibernate 2.1

堆栈跟踪如下。

我们无法在任何其他环境中模拟此情况。

代码段：

    if(persistObj == null)
        return;

    Session session = sess; 
    try {
        if(session == null)
            session = HibernateUtil.getSession();

        if(LOG.isDebugEnabled() && 
           !(persistObj instanceof NonLoggable))
            log("update", persistObj);

        session.update(persistObj);

        if(flush)
            session.flush();

    } catch(StaleObjectStateException ex) {
        throw new HibernateStaleObjectException(ex);

    }

Answer 1

您在更新后重新获取persistObj吗？（您的代码没有显示）

如果没有，则会因为您更新persistObj而发生这种情况。更新完成后，您的类实例中有一个“旧”版本的persistObj。如果您想再次更新persistObj，则需要再次获取persistObj的“当前”版本。
