org.hibernate.AssertionFailure

hibernate

我的线程执行时,有时会收到这个奇怪的错误。这可能与什么有关?

2011-Jun-25 09:05:22,339 ERROR AssertionFailure:45 - an assertion failure occured (this             may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)

我的插入代码

    Transaction tx = null;
    Session session = sessionFactory.openSession();
    tx = session.beginTransaction();

    int count = 0;
    try
    {
        for (Iterator itrList = statusToInsert.iterator(); itrList.hasNext();) 
        {
            try 
            {
                IRecord record = (IRecord) itrList.next();
                session.save(record);
                count++;
                if ( count % 10 == 0 ) 
                { 
                    session.flush();
                    session.clear();
                    tx.commit();
                    tx = session.beginTransaction();
                }

            }
            catch (Exception e) 
            {
                tx.commit();
                session.close();
                session = sessionFactory.openSession();
                tx = session.beginTransaction();
                StringWriter sw = new StringWriter(); 
                PrintWriter pw = new PrintWriter(sw); 
                e.printStackTrace(pw); 
                log.error(sw.toString());
            }
        }
    }
    catch (Exception e) {
        StringWriter sw = new StringWriter(); 
        PrintWriter pw = new PrintWriter(sw); 
        e.printStackTrace(pw); 
        log.error(sw.toString());
    }
    finally {
        tx.commit();
        session.close();
    }

问候,

问题是您的代码正在处理异常,这在99.9%的情况下是一件很不好的事情,并且正在发生以下情况:

与会话的交互之一在try块中失败,并引发异常。发生这种情况时,会话将处于无效状态,因为它处于不一致状态,因此不能用于 绝对任何内容
。但是您的代码与catch块中的会话进行交互,从而触发断言。

在会话发生异常之后,唯一安全的事情是回滚事务并关闭它。任何其他类型的交互都可能会生成另一个异常(在这种情况下为断言异常)。
