我有一个Jboss，Seam，Hibernate和h2的应用程序。我写了一个简单的操作，用于从外部文件将数据导入数据库。
@Name("importAction")
@AutoCreate
@Scope(ScopeType.CONVERSATION)
@Transactional
public class ImportCosAction extends AbstractAction {
saveOrUpdate(member);
protected void saveOrUpdate(AbstractEntity entity) {
final Session session = getSession();
session.saveOrUpdate(entity);
flushSession();
}
它按预期的数量工作，但是，在某些时候我得到以下异常：

此错误表示您的代码正在使用不再有效的连接（即由于连接错误导致的关闭/销毁连接或由上游某些其他代码关闭缓存连接的应用程序的无效连接缓存）。在您的情况下，池中的连接ID为@3c4b0529。因此，您可以在TRACE级别日志记录中参考此信息，以查看是否可以找出连接关闭的原因（由于某些错误，例如DB终止连接或网络问题或应用程序代码错误地处理连接）。
您应该优化您的代码，以便不会花费很长时间来完成交易。另一个选项是为deploy/transaction-jboss-beans.xml bean增加TransactionManager的事务时间： -
.... 300 ....
默认值为5分钟（300秒）。增加此事务超时可能会有所帮助，但这实际上并不能解决根本原因，即您在应用程序中运行的长时间事务。增加事务处理时间的一个副作用是保持资源更长时间，从而对JBoss中其他服务的性能产生负面影响。
我希望您不打算在制作中使用h2。 h2不适用于持久性的生产用途。
您还应检查数据源设置，以确保未禁用idle-timeout-minutes（设置为0）。默认值为15分钟，如果您的连接在事务之间空闲的时间超过该时间段，则可以增加它。
最后，请确保您没有缓存任何数据源连接对象或语句，这些对象或语句可能会持续过时的连接或语句。
答案 1 :(得分：0)
最近我遇到了同样的问题，在调试之后我发现我在执行Statement之前关闭了连接，确保你的连接仍然是OPEN和VALID。
答案 2 :(得分：0)
我遇到了同样的问题。就我而言，问题是我尝试在仅执行读取操作的连接上调用 commit 或 rollback。
